Theoretical Research: Definition, Methods + Examples

Theoretical research allows to explore and analyze a research topic by employing abstract theoretical structures and philosophical concepts.

Research is the careful study of a particular research problem or concern using the scientific method. A theory is essential for any research project because it gives it direction and helps prove or disprove something. Theoretical basis helps us figure out how things work and why we do certain things.

Theoretical research lets you examine and discuss a research object using philosophical ideas and abstract theoretical structures.

In theoretical research, you can’t look at the research object directly. With the help of research literature, your research aims to define and sketch out the chosen topic’s conceptual models, explanations, and structures.

LEARN ABOUT: Research Process Steps

This blog will cover theoretical research and why it is essential. In addition to that, we are going to go over some examples.

What is the theoretical research?

Theoretical research is the systematic examination of a set of beliefs and assumptions.

It aims to learn more about a subject and help us understand it better. The information gathered in this way is not used for anything in particular because this kind of research aims to learn more.

All professionals, like biologists, chemists, engineers, architects, philosophers, writers, sociologists, historians, etc., can do theoretical research. No matter what field you work in, theoretical research is the foundation for new ideas.

It tries to answer basic questions about people, which is why this kind of research is used in every field of knowledge.

For example , a researcher starts with the idea that we need to understand the world around us. To do this, he begins with a hypothesis and tests it through experiments that will help him develop new ideas. 

What is the theoretical framework?

A theoretical framework is a critical component in research that provides a structured foundation for investigating a specific topic or problem. It encompasses a set of interconnected theories, existing theories, and concepts that guide the entire research process. 

The theoretical framework introduces a comprehensive understanding of the subject matter. Also, the theoretical framework strengthens the research’s validity and specifies the key elements that will be explored. Furthermore, it connects different ideas and theories, forming a cohesive structure that underpins the research endeavor.

A complete theoretical framework consists of a network of theories, existing theories, and concepts that collectively shape the direction of a research study. 

The theoretical framework is the fundamental principle that will be explored, strengthens the research’s credibility by aligning it with established knowledge, specifies the variables under investigation, and connects different aspects of the research to create a unified approach.

Theoretical frameworks are the intellectual scaffolding upon which the research is constructed. It is the lens through which researchers view their subject, guiding their choice of methodologies, data collection, analysis, and interpretation. By incorporating existing theory, and established concepts, a theoretical framework not only grounds the research but also provides a coherent roadmap for exploring the intricacies of the chosen topic.

Benefits of theoretical research

Theoretical research yields a wealth of benefits across various fields, from social sciences to human resource development and political science. Here’s a breakdown of these benefits while incorporating the requested topics:

Predictive power

Theoretical models are the cornerstone of theoretical research. They grant us predictive power, enabling us to forecast intricate behaviors within complex systems, like societal interactions. In political science, for instance, a theoretical model helps anticipate potential outcomes of policy changes.

Understanding human behavior

Drawing from key social science theories, it assists us in deciphering human behavior and societal dynamics. For instance, in the context of human resource development, theories related to motivation and psychology provide insights into how to effectively manage a diverse workforce.

Optimizing workforce

In the realm of human resource development, insights gleaned from theoretical research, along with the research methods knowledge base, help create targeted training programs. By understanding various learning methodologies and psychological factors, organizations can optimize workforce training for better results.

Building on foundations

It doesn’t exist in isolation; it builds upon existing theories. For instance, within the human resource development handbook, theoretical research expands established concepts, refining their applicability to contemporary organizational challenges.

Ethical policy formulation

Within political science, theoretical research isn’t confined to governance structures. It extends to ethical considerations, aiding policymakers in creating policies that balance the collective good with individual rights, ensuring just and fair governance. 

Rigorous investigations

Theoretical research underscores the importance of research methods knowledge base. This knowledge equips researchers in theory-building research methods and other fields to design robust research methodologies, yielding accurate data and credible insights.

Long-term impact

Theoretical research leaves a lasting impact. The theoretical models and insights from key social science theories provide enduring frameworks for subsequent research, contributing to the cumulative growth of knowledge in these fields.

Innovation and practical applications

It doesn’t merely remain theoretical. It inspires innovation and practical applications. By merging insights from diverse theories and fields, practitioners in human resource development devise innovative strategies to foster employee growth and well-being.

Theoretical research method

Researchers follow so many methods when doing research. There are two types of theoretical research methods.

  • Scientific methods
  • Social science method 

Let’s explore them below:

theoretical-research-method

Scientific method

Scientific methods have some important points that you should know. Let’s figure them out below:

  • Observation: Any part you want to explain can be found through observation. It helps define the area of research.
  • Hypothesis: The hypothesis is the idea put into words, which helps us figure out what we see.
  • Experimentation: Hypotheses are tested through experiments to see if they are true. These experiments are different for each research.
  • Theory: When we create a theory, we do it because we believe it will explain hypotheses of higher probability.
  • Conclusions: Conclusions are the learnings we derive from our investigation.

Social science methods

There are different methods for social science theoretical research. It consists of polls, documentation, and statistical analysis.

  • Polls: It is a process whereby the researcher uses a topic-specific questionnaire to gather data. No changes are made to the environment or the phenomenon where the polls are conducted to get the most accurate results. QuestionPro live polls are a great way to get live audiences involved and engaged.
  • Documentation: Documentation is a helpful and valuable technique that helps the researcher learn more about the subject. It means visiting libraries or other specialized places, like documentation centers, to look at the existing bibliography. With the documentation, you can find out what came before the investigated topic and what other investigations have found. This step is important because it shows whether or not similar investigations have been done before and what the results were.
  • Statistic analysis : Statistics is a branch of math that looks at random events and differences. It follows the rules that are established by probability. It’s used a lot in sociology and language research. 

Examples of theoretical research

We talked about theoretical study methods in the previous part. We’ll give you some examples to help you understand it better.

Example 1: Theoretical research into the health benefits of hemp

The plant’s active principles are extracted and evaluated, and by studying their components, it is possible to determine what they contain and whether they can potentially serve as a medication.

Example 2: Linguistics research

Investigate to determine how many people in the Basque Country speak Basque. Surveys can be used to determine the number of native Basque speakers and those who speak Basque as a second language.

Example 3: Philosophical research

Research politics and ethics as they are presented in the writings of Hanna Arendt from a theoretical perspective.

LEARN ABOUT: 12 Best Tools for Researchers

From our above discussion, we learned about theoretical research and its methods and gave some examples. It explains things and leads to more knowledge for the sake of knowledge. This kind of research tries to find out more about a thing or an idea, but the results may take time to be helpful in the real world. 

This research is sometimes called basic research. Theoretical research is an important process that gives researchers valuable data with insight.

QuestionPro is a strong platform for managing your data. You can conduct simple surveys to more complex research using QuestionPro survey software.

At QuestionPro, we give researchers tools for collecting data, such as our survey software and a library of insights for any long-term study. Contact our expert team to find out more about it.

Theories, Theoretical Perspective & Theoretical Framework

Theories help us to understand the world by describing, explaining or predicting  how or why a phenomena occurs. Theories can have different levels of scope.  For example, macro level theories look at large global issues, while meso and micro level theories deal with context based or individual issues, respectively ( Salmons , 2019). 

Theoretical Perspective

Your theoretical perspective is the lens with which you view the world.  Theoretical perspective are based on different paradigms.  The research paradigm consists of Ontology (what is reality?); epistemology (how can I know reality?); theoretical perspective (which approach do I use to know something?); Methodology (how do I go about finding out?); Method (what techniques do you use to find out?) ( Patel , 2015)

This  chart may help you to articulate your own theoretical perspective

Theoretical Framework

Your theoretical framework won’t be defined in the literature, it has a specific purpose that is unique to your research project, which you develop based on its suitability to your research.  You will need to review key theories, and evidence from researchers in your area, around this subject in order to present and justify your own choice of theoretical framework. Your theoretical framework should;

  • Identify and justify your theoretical perspective or approach to research.
  • Illustrate your understanding of how theory, methodology and methods are connected.
  • Justify your choice of methodology and methods.
  • Inform readers and future researchers about your choice of research question and the type of results that can be expected from your research.
  • Identify the limitations of your research.
  • Illustrate how your research is connected to other research that shares your approaches

4.2 The Variety of Theories in Psychology

Learning objectives.

  • Describe three dimensions along which theories in psychology vary.
  • Give examples of several different types of theories in psychology.

Researchers in psychology have found that many different types of theories can help them to organize phenomena, predict what will happen in new situations, and generate new research. It is important for beginning researchers to be aware of the different types so that they recognize theories when they see them in the research literature. (They are not always clearly labeled as “theories.”) It is also important for them to see that some types of theories are well within their ability to understand, use, and even construct. In this section, we look at the variety of psychological theories in terms of three important dimensions: formality, scope, and theoretical approach.

Psychological theories vary widely in their formality —the extent to which the components of the theory and the relationships among them are specified clearly and in detail. At the informal end of this dimension are theories that consist of simple verbal descriptions of a few important components and relationships. The habituation theory of expressive-writing effects on health is relatively informal in this sense. So is the drive theory of social facilitation and inhibition. At the more precise, formal end of this dimension are theories that are expressed in terms of mathematical equations or computer programs.

Formal Theories in Psychology

People who are not familiar with scientific psychology are sometimes surprised to learn that psychological theories can take the form of mathematical equations and computer programs. The following formal theories are among the best known and most successful in the field.

  • ACT-R. A comprehensive theory of human cognition that is akin to a programming language, within which more specific models can be created. See http://act-r.psy.cmu.edu .
  • Prospect theory. A formal theory of decision making under uncertainty. Psychologist Daniel Kahneman won the Nobel Prize in economics based in part on prospect theory. Read about Kahneman’s Nobel Prize work at http://www.nobelprize.org/nobel_prizes/economics/laureates/2002/kahneman-autobio.html .
  • Rescorla-Wagner model. A theory of classical conditioning that features an equation describing how the strength of the association between unconditioned and conditioned stimuli changes when the two are paired. For more on this formal theory—including an interactive version—see http://psych.hanover.edu/javatest/rescrolawagner .

Both informal and formal theories have their place in psychological research. Informal theories tend to be easier to create and to understand but less precise in their predictions, which can make them more difficult to test. They are especially appropriate, however, in the early stages of research when the phenomena of interest have not yet been described in detail. Formal theories tend to be more difficult to create and to understand—sometimes requiring a certain amount of mathematical or computer programming background—but they also tend to be more precise in their predictions and therefore easier to test. They are especially appropriate in the later stages of research when the phenomena of interest have been described in detail

Theories in psychology also vary widely in their scope —the number and diversity of the phenomena they explain or interpret. Many early psychological theories were extremely broad in that they attempted to interpret essentially all human behavior. Freud and his followers, for example, applied his theory not only to understanding psychological disorders but also to slips of the tongue and other everyday errors, dreaming, sexuality, art, politics, and even civilization itself (Fine, 1979). Such theories have fallen out of favor in scientific psychology, however, because they tend to be imprecise and difficult to test. In addition, they have not been particularly successful at organizing or predicting the range and complexity of human behavior at the level of detail that scientific researchers usually seek.

Still, contemporary theories in psychology can vary in their scope. At the broad end of this dimension are theories that apply to many diverse phenomena. Cognitive dissonance theory, for example, assumes that when people hold inconsistent beliefs, this creates mental discomfort that they are motivated to reduce by changing one or both of the beliefs. This theory has been applied to a wide variety of phenomena, including the persistence of irrational beliefs and behaviors (e.g., smoking), the effectiveness of certain persuasion and sales techniques (e.g., asking for a small favor before asking for a big one), and even placebo effects. At the narrow end of this dimension are theories that apply to a small number of closely related phenomena. Consider, for example, a very specific quantitative ability called subitizing. This refers to people’s ability to quickly and accurately perceive the number of objects in a scene without counting them—as long as the number is four or fewer. Several theories have been proposed to explain subitizing. Among them is the idea that small numbers of objects are associated with easily recognizable patterns. For example, people know immediately that there are three objects in a scene because the three objects tend to form a “triangle” and it is this pattern that is quickly perceived (Logan & Sbrodoff, 2003).

As with informal and formal theories, both broad and narrow theories have their place in psychological research. Broad theories organize more phenomena but tend to be less formal and less precise in their predictions. Narrow theories organize fewer phenomena but tend to be more formal and more precise in their predictions.

Theoretical Approach

In addition to varying in formality and scope, theories in psychology vary widely in the kinds of theoretical ideas they are constructed from. We will refer to this as the theoretical approach .

Functional theories explain psychological phenomena in terms of their function or purpose. For example, one prominent theory of repeated self-injury (e.g., cutting) is that people do it because it produces a short-term reduction in the intensity of negative emotions that they are feeling (Tantam & Huband, 2009). Note that this theory does not focus on how this happens, but on the function of self-injury for the people who engage in it. Theories from the perspective of evolutionary psychology also tend to be functional—assuming that human behavior has evolved to solve specific adaptive problems faced by our distant ancestors. Consider the phenomenon of sex differences in human mating strategies (Buss & Schmitt, 1993). Men are somewhat more likely than women to seek short-term partners and to value physical attractiveness over material resources in a mate. Women are somewhat more likely than men to seek long-term partners and to value material resources over physical attractiveness in a mate. But why? The standard evolutionary theory holds that because the male investment in becoming a parent is relatively small, men reproduce more successfully by seeking several short-term partners who are young and healthy (which is signaled by physical attractiveness). But because the female investment in becoming a parent is quite large, women reproduce more successfully by seeking a long-term partner who has resources to contribute to raising the child.

Mechanistic theories , on the other hand, focus on specific variables, structures, and processes, and how they interact to produce the phenomena. The drive theory of social facilitation and inhibition and the multistore model of human memory are mechanistic theories in this sense. Figure 4.4 “Simplified Representation of One Contemporary Theory of Hypochondriasis” represents another example—a contemporary cognitive theory of hypochondriasis—an extreme form of health anxiety in which people misinterpret ordinary bodily symptoms (e.g., headaches) as signs of a serious illness (e.g., a brain tumor; Williams, 2004). This theory specifies several key variables and the relationships among them. Specifically, people who are high in the personality trait of neuroticism (also called negative emotionality) start to pay excessive attention to negative health information—especially if they have had a significant illness experience as a child (e.g., a seriously ill parent). This attention to negative health information then leads to health anxiety and hypochondriasis, especially among people who are low in effortful control, which is the ability to shift attention away from negative thoughts and feelings.

Figure 4.4 Simplified Representation of One Contemporary Theory of Hypochondriasis

Simplified Representation of One Contemporary Theory of Hypochondriasis

This theory focuses on key variables and the relationships among them.

Mechanistic theories can also be expressed in terms of biological structures and processes. With advances in genetics and neuroscience, such theories are becoming increasingly common in psychology. For example, researchers are currently constructing and testing theories that specify the brain structures associated with the storage and rehearsal of information in the short-term store, the transfer of information to the long-term store, and so on. Theories of psychological disorders are also increasingly likely to focus on biological mechanisms. Schizophrenia, for example, has been explained in terms of several biological theories, including theories that focus on genetics, neurotransmitters, brain structures, and even prenatal exposure to infections.

Finally, there are also theoretical approaches that provide organization without necessarily providing a functional or mechanistic explanation. These include stage theories , which specify a series of stages that people pass through as they develop or adapt to their environment. Famous stage theories include Abraham Maslow’s hierarchy of needs and Jean Piaget’s theory of cognitive development. Typologies provide organization by categorizing people or behavior into distinct types. These include theories that identify several basic emotions (e.g., happiness, sadness, fear, surprise, anger, and disgust), several distinct types of intelligence (e.g., spatial, linguistic, mathematical, kinesthetic, musical, interpersonal, and intrapersonal), and distinct types of personalities (e.g., Type A vs. Type B).

Researchers in psychology have found that there is a place for all these theoretical approaches. In fact, multiple approaches are probably necessary to provide a complete understanding of any set of phenomena. A complete understanding of emotions, for example, is likely to require identifying the basic emotions that people experience, explaining why we have those emotions, and describing how those emotions work in terms of underlying psychological and biological variables, structures, and processes.

Key Takeaway

  • Theories in psychology vary widely in terms of their formality, scope, and theoretical approach. The different types of theories all play important roles in psychological research.
  • Practice: Find an empirical research report in a professional journal, identify a theory that the researchers present, and then describe the theory in terms of its formality (informal vs. formal), scope (broad vs. narrow), and theoretical approach (functional, mechanistic, etc.).
  • Discussion: Do you think there will ever be a single theory that explains all psychological disorders? Why or why not?

Researching Frameworks

Researching Frameworks: Locating Theoretical and Conceptual Frameworks

Research frameworks provide a foundation for your study and keeps it focused and concise. Think of a framework as a roadmap or blueprint for developing your study and supporting research.

This short video series will help you help you identify, locate, and retrieve theoretical and conceptual frameworks through the library databases and/or Google.

Theoretical Frameworks

Theoretical frameworks provide a particular perspective, or lens, through which to examine a topic. There are many different lenses, such as psychological theories, social theories, organizational theories and economic theories, which may be used to define concepts and explain phenomena. Sometimes these frameworks may come from an area outside of your immediate academic discipline. Using a theoretical framework for your dissertation can help you to better analyze past events by providing a particular set of questions to ask, and a particular perspective to use when examining your topic.

Traditionally, Ph.D. and Applied Degree research must include relevant theoretical framework(s) to frame, or inform, every aspect of the dissertation. Further, Ph.D. dissertations should make an original contribution to the field by adding support for the theory, or, conversely, demonstrating ways in which the theory may not be as explanatory as originally thought. You can learn more about the theoretical framework requirements in the NU Dissertation Center .

It can be difficult to find scholarly work that takes a particular theoretical approach because articles, books, and book chapters are typically described according to the topics they tackle rather than the methods they use to tackle them. Further, there is no single database or search technique for locating theoretical information. However, the suggestions below provide techniques for locating possible theoretical frameworks and theorists in the Library databases. In addition to your Library research, you should discuss possible theories your Dissertation Chair to ensure they align with your study. Also, keep in mind that you will probably find and discard several potential theoretical frameworks before one is finally chosen.

  • The Theoretical Framework Guide from the NU Center for Teaching and Learning
  • Theoretical Frameworks Entry from the The SAGE Encyclopedia of Qualitative Research Methods
  • Theoretical Frameworks in Qualitative Research Book effectively explains, through discussion and example, what a theoretical framework is, how it is used in qualitative research, and the effects it has on the research process.

Conceptual Frameworks

A conceptual framework provides the concept or set of related concepts supporting the basis or foundation of a study. It creates a conceptual model for possible strategies or courses of action identified as important for researching a particular problem or issue. While a conceptual framework is often referred to interchangeably with a theoretical framework, it maintains a distinct purpose. A conceptual framework is used to clarify concepts, organize ideas, and identify relationships with which to frame a study. Concepts are logically developed and organized to support an overall framework and often exhibited graphically within dissertation research. Note that a dissertation may include both a theoretical framework and a conceptual framework.

The suggestions below provide techniques for locating possible conceptual frameworks in the Library databases. Note when examples may use the term "theoretical framework," you may change your search terms to "conceptual framework." In addition to your Library research, you should discuss possible frameworks your Dissertation Chair to ensure they align with your study. Also, keep in mind that you will probably find and discard several potential conceptual frameworks before one is finally chosen.

Use the Library’s e-book databases to gather background information on a particular theory or theorist. Since the e-book databases will contain fewer resources than a database containing thousands of scholarly journal articles, it is best to keep your search terms a little more broad.

For example, a search for education theory in the Ebook Central database results in many relevant e-books, as shown below. Expanding the Table of Contents will provide additional details about the e-book.

Ebook Central search results screen showing books related to education theories.

Encyclopedias and handbooks will also provide reliable background information on particular theories. For example, a search for cognitive developmental theory in the Credo Reference database results in a number of reference entries which discuss the history of the theory, identify relevant theorists, and cite seminal research studies.

Credo Reference search results screen for cognitive developmental theory.

You may search for theorists and theoretical information using Google and Google Scholar , as well. However, please keep in mind that you will need to be more discriminating when it comes to using material found on open access websites. We recommend reviewing the Website Evaluation guidelines when considering online sources.

One method that may be used in Google is limiting your search by a particular domain name. If a website ends in .org, .gov, or .edu, it is more likely to be a scholarly source. If it ends in .com or .net it is less likely to be a scholarly source. In the search below, for example, we have limited our search for "leadership theories" to just those websites ending with .edu. You may also find this domain limiter under Tools>Advanced Search.

Note: Limiting to a particular domain is not necessary in Google Scholar, as all results in Google Scholar may be considered scholarly. This may include articles, theses, books, abstracts and court opinions, material from academic publishers, professional societies, online repositories, universities and other web sites.

Purpose: A key multidisciplinary database for most topics. It is one of the library’s main search engines and the most comprehensive single search. 

Note: Certain library databases and publisher content are not searchable in NavigatorSearch, and individual databases may need to be searched to retrieve information due to unique content. NavigatorSearch can be found at https://resources.nu.edu .

On the NavigatorSearchscreen, include theor* as one your search terms, as shown below. It will retrieve results that include one of the following keywords: theory, theories, theoretical, theorist, or theorists . It is important to keep in mind, however, that this is not a foolproof method for locating theoretical frameworks. Scholars will often cite theory or theorists in order to refute them, or because they are saying something that's tangentially related, or they may even just refer to theory briefly in passing. In our example, we have selected the field for AB Abstract because if theory is mentioned within the abstract, the study is more likely to take a theoretical approach.

Theories and Frameworks: Theories and Frameworks

Theoretical & conceptual frameworks.

The terms theoretical framework and conceptual framework are often used interchangeably to mean the same thing. Although they are both used to understand a research problem and guide the development, collection, and analysis of research, it's important to understand the difference between the two. When working on coursework or dissertation research, make sure to clarify what is being asked and any specific course or program requirements. 

Theoretical framework 

A theoretical framework is a single formal theory. When a study is designed around a theoretical framework, the theory is the primary means in which the research problem is understood and investigated. Although theoretical frameworks tend to be used in quantitative studies, you will also see this approach in qualitative research.  

Conceptual framework

A conceptual framework includes one or more formal theories (in part or whole) as well as other concepts and empirical findings from the literature. It is used to show relationships among these ideas and how they relate to the research study. Conceptual frameworks are commonly seen in qualitative research in the social and behavioral sciences, for example, because often one theory cannot fully address the phenomena being studied.

Types of Research – Explained with Examples

Picture of DiscoverPhDs

Types of Research Design

Types of Research

Research is about using established methods to investigate a problem or question in detail with the aim of generating new knowledge about it.

It is a vital tool for scientific advancement because it allows researchers to prove or refute hypotheses based on clearly defined parameters, environments and assumptions. Due to this, it enables us to confidently contribute to knowledge as it allows research to be verified and replicated.

Knowing the types of research and what each of them focuses on will allow you to better plan your project, utilises the most appropriate methodologies and techniques and better communicate your findings to other researchers and supervisors.

Classification of Types of Research

There are various types of research that are classified according to their objective, depth of study, analysed data, time required to study the phenomenon and other factors. It’s important to note that a research project will not be limited to one type of research, but will likely use several.

According to its Purpose

Theoretical research.

Theoretical research, also referred to as pure or basic research, focuses on generating knowledge , regardless of its practical application. Here, data collection is used to generate new general concepts for a better understanding of a particular field or to answer a theoretical research question.

Results of this kind are usually oriented towards the formulation of theories and are usually based on documentary analysis, the development of mathematical formulas and the reflection of high-level researchers.

Applied Research

Here, the goal is to find strategies that can be used to address a specific research problem. Applied research draws on theory to generate practical scientific knowledge, and its use is very common in STEM fields such as engineering, computer science and medicine.

This type of research is subdivided into two types:

  • Technological applied research : looks towards improving efficiency in a particular productive sector through the improvement of processes or machinery related to said productive processes.
  • Scientific applied research : has predictive purposes. Through this type of research design, we can measure certain variables to predict behaviours useful to the goods and services sector, such as consumption patterns and viability of commercial projects.

Methodology Research

According to your Depth of Scope

Exploratory research.

Exploratory research is used for the preliminary investigation of a subject that is not yet well understood or sufficiently researched. It serves to establish a frame of reference and a hypothesis from which an in-depth study can be developed that will enable conclusive results to be generated.

Because exploratory research is based on the study of little-studied phenomena, it relies less on theory and more on the collection of data to identify patterns that explain these phenomena.

Descriptive Research

The primary objective of descriptive research is to define the characteristics of a particular phenomenon without necessarily investigating the causes that produce it.

In this type of research, the researcher must take particular care not to intervene in the observed object or phenomenon, as its behaviour may change if an external factor is involved.

Explanatory Research

Explanatory research is the most common type of research method and is responsible for establishing cause-and-effect relationships that allow generalisations to be extended to similar realities. It is closely related to descriptive research, although it provides additional information about the observed object and its interactions with the environment.

Correlational Research

The purpose of this type of scientific research is to identify the relationship between two or more variables. A correlational study aims to determine whether a variable changes, how much the other elements of the observed system change.

According to the Type of Data Used

Qualitative research.

Qualitative methods are often used in the social sciences to collect, compare and interpret information, has a linguistic-semiotic basis and is used in techniques such as discourse analysis, interviews, surveys, records and participant observations.

In order to use statistical methods to validate their results, the observations collected must be evaluated numerically. Qualitative research, however, tends to be subjective, since not all data can be fully controlled. Therefore, this type of research design is better suited to extracting meaning from an event or phenomenon (the ‘why’) than its cause (the ‘how’).

Quantitative Research

Quantitative research study delves into a phenomena through quantitative data collection and using mathematical, statistical and computer-aided tools to measure them . This allows generalised conclusions to be projected over time.

Types of Research Methodology

According to the Degree of Manipulation of Variables

Experimental research.

It is about designing or replicating a phenomenon whose variables are manipulated under strictly controlled conditions in order to identify or discover its effect on another independent variable or object. The phenomenon to be studied is measured through study and control groups, and according to the guidelines of the scientific method.

Non-Experimental Research

Also known as an observational study, it focuses on the analysis of a phenomenon in its natural context. As such, the researcher does not intervene directly, but limits their involvement to measuring the variables required for the study. Due to its observational nature, it is often used in descriptive research.

Quasi-Experimental Research

It controls only some variables of the phenomenon under investigation and is therefore not entirely experimental. In this case, the study and the focus group cannot be randomly selected, but are chosen from existing groups or populations . This is to ensure the collected data is relevant and that the knowledge, perspectives and opinions of the population can be incorporated into the study.

According to the Type of Inference

Deductive investigation.

In this type of research, reality is explained by general laws that point to certain conclusions; conclusions are expected to be part of the premise of the research problem and considered correct if the premise is valid and the inductive method is applied correctly.

Inductive Research

In this type of research, knowledge is generated from an observation to achieve a generalisation. It is based on the collection of specific data to develop new theories.

Hypothetical-Deductive Investigation

It is based on observing reality to make a hypothesis, then use deduction to obtain a conclusion and finally verify or reject it through experience.

Descriptive Research Design

According to the Time in Which it is Carried Out

Longitudinal study (also referred to as diachronic research).

It is the monitoring of the same event, individual or group over a defined period of time. It aims to track changes in a number of variables and see how they evolve over time. It is often used in medical, psychological and social areas .

Cross-Sectional Study (also referred to as Synchronous Research)

Cross-sectional research design is used to observe phenomena, an individual or a group of research subjects at a given time.

According to The Sources of Information

Primary research.

This fundamental research type is defined by the fact that the data is collected directly from the source, that is, it consists of primary, first-hand information.

Secondary research

Unlike primary research, secondary research is developed with information from secondary sources, which are generally based on scientific literature and other documents compiled by another researcher.

Action Research Methods

According to How the Data is Obtained

Documentary (cabinet).

Documentary research, or secondary sources, is based on a systematic review of existing sources of information on a particular subject. This type of scientific research is commonly used when undertaking literature reviews or producing a case study.

Field research study involves the direct collection of information at the location where the observed phenomenon occurs.

From Laboratory

Laboratory research is carried out in a controlled environment in order to isolate a dependent variable and establish its relationship with other variables through scientific methods.

Mixed-Method: Documentary, Field and/or Laboratory

Mixed research methodologies combine results from both secondary (documentary) sources and primary sources through field or laboratory research.

Theories are formulated to explain, predict, and understand phenomena and, in many cases, to challenge and extend existing knowledge within the limits of critical bounded assumptions or predictions of behavior. The theoretical framework is the structure that can hold or support a theory of a research study. The theoretical framework encompasses not just the theory, but the narrative explanation about how the researcher engages in using the theory and its underlying assumptions to investigate the research problem. It is the structure of your paper that summarizes concepts, ideas, and theories derived from prior research studies and which was synthesized in order to form a conceptual basis for your analysis and interpretation of meaning found within your research.

Importance of Theory and a Theoretical Framework

Theories can be unfamiliar to the beginning researcher because they are rarely applied in high school social studies curriculum and, as a result, can come across as unfamiliar and imprecise when first introduced as part of a writing assignment. However, in their most simplified form, a theory is simply a set of assumptions or predictions about something you think will happen based on existing evidence and that can be tested to see if those outcomes turn out to be true. Of course, it is slightly more deliberate than that, therefore, summarized from Kivunja (2018, p. 46), here are the essential characteristics of a theory.

  • It is logical and coherent
  • It has clear definitions of terms or variables, and has boundary conditions [i.e., it is not an open-ended statement]
  • It has a domain where it applies
  • It has clearly described relationships among variables
  • It describes, explains, and makes specific predictions
  • It comprises of concepts, themes, principles, and constructs
  • It must have been based on empirical data [i.e., it is not a guess]
  • It must have made claims that are subject to testing, been tested and verified
  • It must be clear and concise
  • Its assertions or predictions must be different and better than those in existing theories
  • Its predictions must be general enough to be applicable to and understood within multiple contexts
  • Its assertions or predictions are relevant, and if applied as predicted, will result in the predicted outcome
  • The assertions and predictions are not immutable, but subject to revision and improvement as researchers use the theory to make sense of phenomena
  • Its concepts and principles explain what is going on and why
  • Its concepts and principles are substantive enough to enable us to predict a future

Given these characteristics, a theory can best be understood as the foundation from which you investigate assumptions or predictions derived from previous studies about the research problem, but in a way that leads to new knowledge and understanding as well as, in some cases, discovering how to improve the relevance of the theory itself or to argue that the theory is outdated and a new theory needs to be formulated based on new evidence.

A theoretical framework consists of concepts and, together with their definitions and reference to relevant scholarly literature, existing theory that is used for your particular study. The theoretical framework must demonstrate an understanding of theories and concepts that are relevant to the topic of your research paper and that relate to the broader areas of knowledge being considered.

The theoretical framework is most often not something readily found within the literature . You must review course readings and pertinent research studies for theories and analytic models that are relevant to the research problem you are investigating. The selection of a theory should depend on its appropriateness, ease of application, and explanatory power.

The theoretical framework strengthens the study in the following ways :

  • An explicit statement of  theoretical assumptions permits the reader to evaluate them critically.
  • The theoretical framework connects the researcher to existing knowledge. Guided by a relevant theory, you are given a basis for your hypotheses and choice of research methods.
  • Articulating the theoretical assumptions of a research study forces you to address questions of why and how. It permits you to intellectually transition from simply describing a phenomenon you have observed to generalizing about various aspects of that phenomenon.
  • Having a theory helps you identify the limits to those generalizations. A theoretical framework specifies which key variables influence a phenomenon of interest and highlights the need to examine how those key variables might differ and under what circumstances.
  • The theoretical framework adds context around the theory itself based on how scholars had previously tested the theory in relation their overall research design [i.e., purpose of the study, methods of collecting data or information, methods of analysis, the time frame in which information is collected, study setting, and the methodological strategy used to conduct the research].

By virtue of its applicative nature, good theory in the social sciences is of value precisely because it fulfills one primary purpose: to explain the meaning, nature, and challenges associated with a phenomenon, often experienced but unexplained in the world in which we live, so that we may use that knowledge and understanding to act in more informed and effective ways.

Strategies for Developing the Theoretical Framework

I.  Developing the Framework

Here are some strategies to develop of an effective theoretical framework:

  • Examine your thesis title and research problem . The research problem anchors your entire study and forms the basis from which you construct your theoretical framework.
  • Brainstorm about what you consider to be the key variables in your research . Answer the question, "What factors contribute to the presumed effect?"
  • Review related literature to find how scholars have addressed your research problem. Identify the assumptions from which the author(s) addressed the problem.
  • List  the constructs and variables that might be relevant to your study. Group these variables into independent and dependent categories.
  • Review key social science theories that are introduced to you in your course readings and choose the theory that can best explain the relationships between the key variables in your study [note the Writing Tip on this page].
  • Discuss the assumptions or propositions of this theory and point out their relevance to your research.

A theoretical framework is used to limit the scope of the relevant data by focusing on specific variables and defining the specific viewpoint [framework] that the researcher will take in analyzing and interpreting the data to be gathered. It also facilitates the understanding of concepts and variables according to given definitions and builds new knowledge by validating or challenging theoretical assumptions.

II.  Purpose

Think of theories as the conceptual basis for understanding, analyzing, and designing ways to investigate relationships within social systems. To that end, the following roles served by a theory can help guide the development of your framework.

  • Means by which new research data can be interpreted and coded for future use,
  • Response to new problems that have no previously identified solutions strategy,
  • Means for identifying and defining research problems,
  • Means for prescribing or evaluating solutions to research problems,
  • Ways of discerning certain facts among the accumulated knowledge that are important and which facts are not,
  • Means of giving old data new interpretations and new meaning,
  • Means by which to identify important new issues and prescribe the most critical research questions that need to be answered to maximize understanding of the issue,
  • Means of providing members of a professional discipline with a common language and a frame of reference for defining the boundaries of their profession, and
  • Means to guide and inform research so that it can, in turn, guide research efforts and improve professional practice.

Structure and Writing Style

The theoretical framework may be rooted in a specific theory , in which case, your work is expected to test the validity of that existing theory in relation to specific events, issues, or phenomena. Many social science research papers fit into this rubric. For example, Peripheral Realism Theory, which categorizes perceived differences among nation-states as those that give orders, those that obey, and those that rebel, could be used as a means for understanding conflicted relationships among countries in Africa. A test of this theory could be the following: Does Peripheral Realism Theory help explain intra-state actions, such as, the disputed split between southern and northern Sudan that led to the creation of two nations?

However, you may not always be asked by your professor to test a specific theory in your paper, but to develop your own framework from which your analysis of the research problem is derived . Based upon the above example, it is perhaps easiest to understand the nature and function of a theoretical framework if it is viewed as an answer to two basic questions:

  • What is the research problem/question? [e.g., "How should the individual and the state relate during periods of conflict?"]
  • Why is your approach a feasible solution? [i.e., justify the application of your choice of a particular theory and explain why alternative constructs were rejected. I could choose instead to test Instrumentalist or Circumstantialists models developed among ethnic conflict theorists that rely upon socio-economic-political factors to explain individual-state relations and to apply this theoretical model to periods of war between nations].

The answers to these questions come from a thorough review of the literature and your course readings [summarized and analyzed in the next section of your paper] and the gaps in the research that emerge from the review process. With this in mind, a complete theoretical framework will likely not emerge until after you have completed a thorough review of the literature .

Just as a research problem in your paper requires contextualization and background information, a theory requires a framework for understanding its application to the topic being investigated. When writing and revising this part of your research paper, keep in mind the following:

  • Clearly describe the framework, concepts, models, or specific theories that underpin your study . This includes noting who the key theorists are in the field who have conducted research on the problem you are investigating and, when necessary, the historical context that supports the formulation of that theory. This latter element is particularly important if the theory is relatively unknown or it is borrowed from another discipline.
  • Position your theoretical framework within a broader context of related frameworks, concepts, models, or theories . As noted in the example above, there will likely be several concepts, theories, or models that can be used to help develop a framework for understanding the research problem. Therefore, note why the theory you've chosen is the appropriate one.
  • The present tense is used when writing about theory. Although the past tense can be used to describe the history of a theory or the role of key theorists, the construction of your theoretical framework is happening now.
  • You should make your theoretical assumptions as explicit as possible . Later, your discussion of methodology should be linked back to this theoretical framework.
  • Don’t just take what the theory says as a given! Reality is never accurately represented in such a simplistic way; if you imply that it can be, you fundamentally distort a reader's ability to understand the findings that emerge. Given this, always note the limitations of the theoretical framework you've chosen [i.e., what parts of the research problem require further investigation because the theory inadequately explains a certain phenomena].

Writing Tip

Borrowing Theoretical Constructs from Other Disciplines

An increasingly important trend in the social and behavioral sciences is to think about and attempt to understand research problems from an interdisciplinary perspective. One way to do this is to not rely exclusively on the theories developed within your particular discipline, but to think about how an issue might be informed by theories developed in other disciplines. For example, if you are a political science student studying the rhetorical strategies used by female incumbents in state legislature campaigns, theories about the use of language could be derived, not only from political science, but linguistics, communication studies, philosophy, psychology, and, in this particular case, feminist studies. Building theoretical frameworks based on the postulates and hypotheses developed in other disciplinary contexts can be both enlightening and an effective way to be more engaged in the research topic.

Another Writing Tip

Don't Undertheorize!

Do not leave the theory hanging out there in the introduction never to be mentioned again. Undertheorizing weakens your paper. The theoretical framework you describe should guide your study throughout the paper. Be sure to always connect theory to the review of pertinent literature and to explain in the discussion part of your paper how the theoretical framework you chose supports analysis of the research problem or, if appropriate, how the theoretical framework was found to be inadequate in explaining the phenomenon you were investigating. In that case, don't be afraid to propose your own theory based on your findings.

What's a Theory? What's a Hypothesis?

The terms theory and hypothesis are often used interchangeably in newspapers and popular magazines and in non-academic settings. However, the difference between theory and hypothesis in scholarly research is important, particularly when using an experimental design. A theory is a well-established principle that has been developed to explain some aspect of the natural world. Theories arise from repeated observation and testing and incorporates facts, laws, predictions, and tested assumptions that are widely accepted [e.g., rational choice theory; grounded theory; critical race theory].

A hypothesis is a specific, testable prediction about what you expect to happen in your study. For example, an experiment designed to look at the relationship between study habits and test anxiety might have a hypothesis that states, "We predict that students with better study habits will suffer less test anxiety." Unless your study is exploratory in nature, your hypothesis should always explain what you expect to happen during the course of your research.

The key distinctions are:

  • A theory predicts events in a broad, general context;  a hypothesis makes a specific prediction about a specified set of circumstances.
  • A theory has been extensively tested and is generally accepted among a set of scholars; a hypothesis is a speculative guess that has yet to be tested.

Still Yet Another Writing Tip

Be Prepared to Challenge the Validity of an Existing Theory

Theories are meant to be tested and their underlying assumptions challenged; they are not rigid or intransigent, but are meant to set forth general principles for explaining phenomena or predicting outcomes. Given this, testing theoretical assumptions is an important way that knowledge in any discipline develops and grows. If you're asked to apply an existing theory to a research problem, the analysis will likely include the expectation by your professor that you should offer modifications to the theory based on your research findings.

Indications that theoretical assumptions may need to be modified can include the following:

  • Your findings suggest that the theory does not explain or account for current conditions or circumstances or the passage of time,
  • The study reveals a finding that is incompatible with what the theory attempts to explain or predict, or
  • Your analysis reveals that the theory overly generalizes behaviors or actions without taking into consideration specific factors revealed from your analysis [e.g., factors related to culture, nationality, history, gender, ethnicity, age, geographic location, legal norms or customs , religion, social class, socioeconomic status, etc.].

Methodology

Research Methods | Definitions, Types, Examples

Research methods are specific procedures for collecting and analyzing data. Developing your research methods is an integral part of your research design . When planning your methods, there are two key decisions you will make.

First, decide how you will collect data . Your methods depend on what type of data you need to answer your research question :

  • Qualitative vs. quantitative : Will your data take the form of words or numbers?
  • Primary vs. secondary : Will you collect original data yourself, or will you use data that has already been collected by someone else?
  • Descriptive vs. experimental : Will you take measurements of something as it is, or will you perform an experiment?

Second, decide how you will analyze the data .

  • For quantitative data, you can use statistical analysis methods to test relationships between variables.
  • For qualitative data, you can use methods such as thematic analysis to interpret patterns and meanings in the data.

Data is the information that you collect for the purposes of answering your research question . The type of data you need depends on the aims of your research.

Qualitative vs. quantitative data

Your choice of qualitative or quantitative data collection depends on the type of knowledge you want to develop.

For questions about ideas, experiences and meanings, or to study something that can’t be described numerically, collect qualitative data .

If you want to develop a more mechanistic understanding of a topic, or your research involves hypothesis testing , collect quantitative data .

Quantitative .

You can also take a mixed methods approach , where you use both qualitative and quantitative research methods.

Primary vs. secondary research

Primary research is any original data that you collect yourself for the purposes of answering your research question (e.g. through surveys , observations and experiments ). Secondary research is data that has already been collected by other researchers (e.g. in a government census or previous scientific studies).

If you are exploring a novel research question, you’ll probably need to collect primary data . But if you want to synthesize existing knowledge, analyze historical trends, or identify patterns on a large scale, secondary data might be a better choice.

Descriptive vs. experimental data

In descriptive research , you collect data about your study subject without intervening. The validity of your research will depend on your sampling method .

In experimental research , you systematically intervene in a process and measure the outcome. The validity of your research will depend on your experimental design .

To conduct an experiment, you need to be able to vary your independent variable , precisely measure your dependent variable, and control for confounding variables . If it’s practically and ethically possible, this method is the best choice for answering questions about cause and effect.

Research methods for collecting data
Research method Primary or secondary? Qualitative or quantitative? When to use
Primary Quantitative To test cause-and-effect relationships.
Primary Quantitative To understand general characteristics of a population.
Interview/focus group Primary Qualitative To gain more in-depth understanding of a topic.
Observation Primary Either To understand how something occurs in its natural setting.
Secondary Either To situate your research in an existing body of work, or to evaluate trends within a research topic.
Either Either To gain an in-depth understanding of a specific group or context, or when you don’t have the resources for a large study.

Your data analysis methods will depend on the type of data you collect and how you prepare it for analysis.

Data can often be analyzed both quantitatively and qualitatively. For example, survey responses could be analyzed qualitatively by studying the meanings of responses or quantitatively by studying the frequencies of responses.

Qualitative analysis methods

Qualitative analysis is used to understand words, ideas, and experiences. You can use it to interpret data that was collected:

  • From open-ended surveys and interviews , literature reviews , case studies , ethnographies , and other sources that use text rather than numbers.
  • Using non-probability sampling methods .

Qualitative analysis tends to be quite flexible and relies on the researcher’s judgement, so you have to reflect carefully on your choices and assumptions and be careful to avoid research bias .

Quantitative analysis methods

Quantitative analysis uses numbers and statistics to understand frequencies, averages and correlations (in descriptive studies) or cause-and-effect relationships (in experiments).

You can use quantitative analysis to interpret data that was collected either:

  • During an experiment .
  • Using probability sampling methods .

Because the data is collected and analyzed in a statistically valid way, the results of quantitative analysis can be easily standardized and shared among researchers.

Research methods for analyzing data
Research method Qualitative or quantitative? When to use
Quantitative To analyze data collected in a statistically valid manner (e.g. from experiments, surveys, and observations).
Meta-analysis Quantitative To statistically analyze the results of a large collection of studies.

Can only be applied to studies that collected data in a statistically valid manner.

Qualitative To analyze data collected from interviews, , or textual sources.

To understand general themes in the data and how they are communicated.

Either To analyze large volumes of textual or visual data collected from surveys, literature reviews, or other sources.

Can be quantitative (i.e. frequencies of words) or qualitative (i.e. meanings of words).

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Quantitative methods allow you to systematically measure variables and test hypotheses . Qualitative methods allow you to explore concepts and experiences in more detail.

In mixed methods research , you use both qualitative and quantitative data collection and analysis methods to answer your research question .

A sample is a subset of individuals from a larger population . Sampling means selecting the group that you will actually collect data from in your research. For example, if you are researching the opinions of students in your university, you could survey a sample of 100 students.

In statistics, sampling allows you to test a hypothesis about the characteristics of a population.

The research methods you use depend on the type of data you need to answer your research question .

  • If you want to measure something or test a hypothesis , use quantitative methods . If you want to explore ideas, thoughts and meanings, use qualitative methods .
  • If you want to analyze a large amount of readily-available data, use secondary data. If you want data specific to your purposes with control over how it is generated, collect primary data.
  • If you want to establish cause-and-effect relationships between variables , use experimental methods. If you want to understand the characteristics of a research subject, use descriptive methods.

Methodology refers to the overarching strategy and rationale of your research project . It involves studying the methods used in your field and the theories or principles behind them, in order to develop an approach that matches your objectives.

Methods are the specific tools and procedures you use to collect and analyze data (for example, experiments, surveys , and statistical tests ).

In shorter scientific papers, where the aim is to report the findings of a specific study, you might simply describe what you did in a methods section .

In a longer or more complex research project, such as a thesis or dissertation , you will probably include a methodology section , where you explain your approach to answering the research questions and cite relevant sources to support your choice of methods.

4 Theories in scientific research

As we know from previous chapters, science is knowledge represented as a collection of ‘theories’ derived using the scientific method. In this chapter, we will examine what a theory is, why we need theories in research, the building blocks of a theory, how to evaluate theories, how can we apply theories in research, and also present illustrative examples of five theories frequently used in social science research.

Theories are explanations of a natural or social behaviour, event, or phenomenon. More formally, a scientific theory is a system of constructs (concepts) and propositions (relationships between those constructs) that collectively presents a logical, systematic, and coherent explanation of a phenomenon of interest within some assumptions and boundary conditions (Bacharach 1989). [1]

Theories should explain why things happen, rather than just describe or predict. Note that it is possible to predict events or behaviours using a set of predictors, without necessarily explaining why such events are taking place. For instance, market analysts predict fluctuations in the stock market based on market announcements, earnings reports of major companies, and new data from the Federal Reserve and other agencies, based on previously observed correlations . Prediction requires only correlations. In contrast, explanations require causations , or understanding of cause-effect relationships. Establishing causation requires three conditions: one, correlations between two constructs, two, temporal precedence (the cause must precede the effect in time), and three, rejection of alternative hypotheses (through testing). Scientific theories are different from theological, philosophical, or other explanations in that scientific theories can be empirically tested using scientific methods.

Explanations can be idiographic or nomothetic. Idiographic explanations are those that explain a single situation or event in idiosyncratic detail. For example, you did poorly on an exam because: you forgot that you had an exam on that day, you arrived late to the exam due to a traffic jam, you panicked midway through the exam, you had to work late the previous evening and could not study for the exam, or even your dog ate your textbook. The explanations may be detailed, accurate, and valid, but they may not apply to other similar situations, even involving the same person, and are hence not generalisable. In contrast, nomothetic explanations seek to explain a class of situations or events rather than a specific situation or event. For example, students who do poorly in exams do so because they did not spend adequate time preparing for exams or because they suffer from nervousness, attention-deficit, or some other medical disorder. Because nomothetic explanations are designed to be generalisable across situations, events, or people, they tend to be less precise, less complete, and less detailed. However, they explain economically, using only a few explanatory variables. Because theories are also intended to serve as generalised explanations for patterns of events, behaviours, or phenomena, theoretical explanations are generally nomothetic in nature.

While understanding theories, it is also important to understand what theories are not. A theory is not data, facts, typologies, taxonomies, or empirical findings. A collection of facts is not a theory, just as a pile of stones is not a house. Likewise, a collection of constructs (e.g., a typology of constructs) is not a theory, because theories must go well beyond constructs to include propositions, explanations, and boundary conditions. Data, facts, and findings operate at the empirical or observational level, while theories operate at a conceptual level and are based on logic rather than observations.

There are many benefits to using theories in research. First, theories provide the underlying logic for the occurrence of natural or social phenomena by explaining the key drivers and outcomes of the target phenomenon, and the underlying processes responsible for driving that phenomenon. Second, they aid in sense-making by helping us synthesise prior empirical findings within a theoretical framework and reconcile contradictory findings by discovering contingent factors influencing the relationship between two constructs in different studies. Third, theories provide guidance for future research by helping identify constructs and relationships that are worthy of further research. Fourth, theories can contribute to cumulative knowledge building by bridging gaps between other theories and by causing existing theories to be re-evaluated in a new light.

However, theories can also have their own share of limitations. As simplified explanations of reality, theories may not always provide adequate explanations of the phenomenon of interest based on a limited set of constructs and relationships. Theories are designed to be simple and parsimonious explanations, while reality may be significantly more complex. Furthermore, theories may impose blinders or limit researchers’ ‘range of vision’, causing them to miss out on important concepts that are not defined by the theory.

Building blocks of a theory

David Whetten (1989) [2] suggests that there are four building blocks of a theory: constructs, propositions, logic, and boundary conditions/assumptions. Constructs capture the ‘what’ of theories (i.e., what concepts are important for explaining a phenomenon?), propositions capture the ‘how’ (i.e., how are these concepts related to each other?), logic represents the ‘why’ (i.e., why are these concepts related?), and boundary conditions/assumptions examines the ‘who, when, and where’ (i.e., under what circumstances will these concepts and relationships work?). Though constructs and propositions were previously discussed in Chapter 2, we describe them again here for the sake of completeness.

Constructs are abstract concepts specified at a high level of abstraction that are chosen specifically to explain the phenomenon of interest. Recall from Chapter 2 that constructs may be unidimensional (i.e., embody a single concept), such as weight or age, or multi-dimensional (i.e., embody multiple underlying concepts), such as personality or culture. While some constructs, such as age, education, and firm size, are easy to understand, others, such as creativity, prejudice, and organisational agility, may be more complex and abstruse, and still others such as trust, attitude, and learning may represent temporal tendencies rather than steady states. Nevertheless, all constructs must have clear and unambiguous operational definitions that should specify exactly how the construct will be measured and at what level of analysis (individual, group, organisational, etc.). Measurable representations of abstract constructs are called variables . For instance, IQ score is a variable that is purported to measure an abstract construct called ‘intelligence’. As noted earlier, scientific research proceeds along two planes: a theoretical plane and an empirical plane. Constructs are conceptualised at the theoretical plane, while variables are operationalised and measured at the empirical (observational) plane. Furthermore, variables may be independent, dependent, mediating, or moderating, as discussed in Chapter 2. The distinction between constructs (conceptualised at the theoretical level) and variables (measured at the empirical level) is shown in Figure 4.1.

Distinction between theoretical and empirical concepts

Propositions are associations postulated between constructs based on deductive logic. Propositions are stated in declarative form and should ideally indicate a cause-effect relationship (e.g., if X occurs, then Y will follow). Note that propositions may be conjectural but must be testable, and should be rejected if they are not supported by empirical observations. However, like constructs, propositions are stated at the theoretical level, and they can only be tested by examining the corresponding relationship between measurable variables of those constructs. The empirical formulation of propositions, stated as relationships between variables, are called hypotheses . The distinction between propositions (formulated at the theoretical level) and hypotheses (tested at the empirical level) is depicted in Figure 4.1.

The third building block of a theory is the logic that provides the basis for justifying the propositions as postulated. Logic acts like a ‘glue’ that connects the theoretical constructs and provides meaning and relevance to the relationships between these constructs. Logic also represents the ‘explanation’ that lies at the core of a theory. Without logic, propositions will be ad hoc, arbitrary, and meaningless, and cannot be tied into the cohesive ‘system of propositions’ that is the heart of any theory.

Finally, all theories are constrained by assumptions about values, time, and space, and boundary conditions that govern where the theory can be applied and where it cannot be applied. For example, many economic theories assume that human beings are rational (or boundedly rational) and employ utility maximisation based on cost and benefit expectations as a way of understand human behaviour. In contrast, political science theories assume that people are more political than rational, and try to position themselves in their professional or personal environment in a way that maximises their power and control over others. Given the nature of their underlying assumptions, economic and political theories are not directly comparable, and researchers should not use economic theories if their objective is to understand the power structure or its evolution in an organisation. Likewise, theories may have implicit cultural assumptions (e.g., whether they apply to individualistic or collective cultures), temporal assumptions (e.g., whether they apply to early stages or later stages of human behaviour), and spatial assumptions (e.g., whether they apply to certain localities but not to others). If a theory is to be properly used or tested, all of the implicit assumptions that form the boundaries of that theory must be properly understood. Unfortunately, theorists rarely state their implicit assumptions clearly, which leads to frequent misapplications of theories to problem situations in research.

Attributes of a good theory

Theories are simplified and often partial explanations of complex social reality. As such, there can be good explanations or poor explanations, and consequently, there can be good theories or poor theories. How can we evaluate the ‘goodness’ of a given theory? Different criteria have been proposed by different researchers, the more important of which are listed below:

Logical consistency: Are the theoretical constructs, propositions, boundary conditions, and assumptions logically consistent with each other? If some of these ‘building blocks’ of a theory are inconsistent with each other (e.g., a theory assumes rationality, but some constructs represent non-rational concepts), then the theory is a poor theory.

Explanatory power: How much does a given theory explain (or predict) reality? Good theories obviously explain the target phenomenon better than rival theories, as often measured by variance explained (R-squared) value in regression equations.

Falsifiability: British philosopher Karl Popper stated in the 1940s that for theories to be valid, they must be falsifiable. Falsifiability ensures that the theory is potentially disprovable, if empirical data does not match with theoretical propositions, which allows for their empirical testing by researchers. In other words, theories cannot be theories unless they can be empirically testable. Tautological statements, such as ‘a day with high temperatures is a hot day’ are not empirically testable because a hot day is defined (and measured) as a day with high temperatures, and hence, such statements cannot be viewed as a theoretical proposition. Falsifiability requires the presence of rival explanations, it ensures that the constructs are adequately measurable, and so forth. However, note that saying that a theory is falsifiable is not the same as saying that a theory should be falsified. If a theory is indeed falsified based on empirical evidence, then it was probably a poor theory to begin with.

Parsimony: Parsimony examines how much of a phenomenon is explained with how few variables. The concept is attributed to fourteenth century English logician Father William of Ockham (and hence called ‘Ockham’s razor’ or ‘Occam’s razor’), which states that among competing explanations that sufficiently explain the observed evidence, the simplest theory (i.e., one that uses the smallest number of variables or makes the fewest assumptions) is the best. Explanation of a complex social phenomenon can always be increased by adding more and more constructs. However, such an approach defeats the purpose of having a theory, which is intended to be a ‘simplified’ and generalisable explanation of reality. Parsimony relates to the degrees of freedom in a given theory. Parsimonious theories have higher degrees of freedom, which allow them to be more easily generalised to other contexts, settings, and populations.

Approaches to theorising

How do researchers build theories? Steinfeld and Fulk (1990) [3] recommend four such approaches. The first approach is to build theories inductively based on observed patterns of events or behaviours. Such an approach is often called ‘grounded theory building’, because the theory is grounded in empirical observations. This technique is heavily dependent on the observational and interpretive abilities of the researcher, and the resulting theory may be subjective and non-confirmable. Furthermore, observing certain patterns of events will not necessarily make a theory, unless the researcher is able to provide consistent explanations for the observed patterns. We will discuss the grounded theory approach in a later chapter on qualitative research.

The second approach to theory building is to conduct a bottom-up conceptual analysis to identify different sets of predictors relevant to the phenomenon of interest using a predefined framework. One such framework may be a simple input-process-output framework, where the researcher may look for different categories of inputs, such as individual, organisational, and/or technological factors potentially related to the phenomenon of interest (the output), and describe the underlying processes that link these factors to the target phenomenon. This is also an inductive approach that relies heavily on the inductive abilities of the researcher, and interpretation may be biased by researcher’s prior knowledge of the phenomenon being studied.

The third approach to theorising is to extend or modify existing theories to explain a new context, such as by extending theories of individual learning to explain organisational learning. While making such an extension, certain concepts, propositions, and/or boundary conditions of the old theory may be retained and others modified to fit the new context. This deductive approach leverages the rich inventory of social science theories developed by prior theoreticians, and is an efficient way of building new theories by expanding on existing ones.

The fourth approach is to apply existing theories in entirely new contexts by drawing upon the structural similarities between the two contexts. This approach relies on reasoning by analogy, and is probably the most creative way of theorising using a deductive approach. For instance, Markus (1987) [4] used analogic similarities between a nuclear explosion and uncontrolled growth of networks or network-based businesses to propose a critical mass theory of network growth. Just as a nuclear explosion requires a critical mass of radioactive material to sustain a nuclear explosion, Markus suggested that a network requires a critical mass of users to sustain its growth, and without such critical mass, users may leave the network, causing an eventual demise of the network.

Examples of social science theories

In this section, we present brief overviews of a few illustrative theories from different social science disciplines. These theories explain different types of social behaviors, using a set of constructs, propositions, boundary conditions, assumptions, and underlying logic. Note that the following represents just a simplistic introduction to these theories. Readers are advised to consult the original sources of these theories for more details and insights on each theory.

Agency theory. Agency theory (also called principal-agent theory), a classic theory in the organisational economics literature, was originally proposed by Ross (1973) [5] to explain two-party relationships—such as those between an employer and its employees, between organisational executives and shareholders, and between buyers and sellers—whose goals are not congruent with each other. The goal of agency theory is to specify optimal contracts and the conditions under which such contracts may help minimise the effect of goal incongruence. The core assumptions of this theory are that human beings are self-interested individuals, boundedly rational, and risk-averse, and the theory can be applied at the individual or organisational level.

The two parties in this theory are the principal and the agent—the principal employs the agent to perform certain tasks on its behalf. While the principal’s goal is quick and effective completion of the assigned task, the agent’s goal may be working at its own pace, avoiding risks, and seeking self-interest—such as personal pay—over corporate interests, hence, the goal incongruence. Compounding the nature of the problem may be information asymmetry problems caused by the principal’s inability to adequately observe the agent’s behaviour or accurately evaluate the agent’s skill sets. Such asymmetry may lead to agency problems where the agent may not put forth the effort needed to get the task done (the moral hazard problem) or may misrepresent its expertise or skills to get the job but not perform as expected (the adverse selection problem). Typical contracts that are behaviour-based, such as a monthly salary, cannot overcome these problems. Hence, agency theory recommends using outcome-based contracts, such as commissions or a fee payable upon task completion, or mixed contracts that combine behaviour-based and outcome-based incentives. An employee stock option plan is an example of an outcome-based contract, while employee pay is a behaviour-based contract. Agency theory also recommends tools that principals may employ to improve the efficacy of behaviour-based contracts, such as investing in monitoring mechanisms—e.g. hiring supervisors—to counter the information asymmetry caused by moral hazard, designing renewable contracts contingent on the agent’s performance (performance assessment makes the contract partially outcome-based), or by improving the structure of the assigned task to make it more programmable and therefore more observable.

Theory of planned behaviour. Postulated by Azjen (1991), [6] the theory of planned behaviour (TPB) is a generalised theory of human behaviour in social psychology literature that can be used to study a wide range of individual behaviours. It presumes that individual behaviour represents conscious reasoned choice, and is shaped by cognitive thinking and social pressures. The theory postulates that behaviours are based on one’s intention regarding that behaviour, which in turn is a function of the person’s attitude toward the behaviour, subjective norm regarding that behaviour, and perception of control over that behaviour (see Figure 4.2). Attitude is defined as the individual’s overall positive or negative feelings about performing the behaviour in question, which may be assessed as a summation of one’s beliefs regarding the different consequences of that behaviour, weighted by the desirability of those consequences. Subjective norm refers to one’s perception of whether people important to that person expect the person to perform the intended behaviour, and is represented as a weighted combination of the expected norms of different referent groups such as friends, colleagues, or supervisors at work. Behavioural control is one’s perception of internal or external controls constraining the behaviour in question. Internal controls may include the person’s ability to perform the intended behaviour (self-efficacy), while external control refers to the availability of external resources needed to perform that behaviour (facilitating conditions). TPB also suggests that sometimes people may intend to perform a given behaviour but lack the resources needed to do so, and therefore posits that behavioural control can have a direct effect on behaviour, in addition to the indirect effect mediated by intention.

TPB is an extension of an earlier theory called the theory of reasoned action, which included attitude and subjective norm as key drivers of intention, but not behavioural control. The latter construct was added by Ajzen in TPB to account for circumstances when people may have incomplete control over their own behaviours (such as not having high-speed Internet access for web surfing).

Innovation diffusion theory. Innovation diffusion theory (IDT) is a seminal theory in the communications literature that explains how innovations are adopted within a population of potential adopters. The concept was first studied by French sociologist Gabriel Tarde, but the theory was developed by Everett Rogers in 1962 based on observations of 508 diffusion studies. The four key elements in this theory are: innovation, communication channels, time, and social system. Innovations may include new technologies, new practices, or new ideas, and adopters may be individuals or organisations. At the macro (population) level, IDT views innovation diffusion as a process of communication where people in a social system learn about a new innovation and its potential benefits through communication channels—such as mass media or prior adopters— and are persuaded to adopt it. Diffusion is a temporal process—the diffusion process starts off slow among a few early adopters, then picks up speed as the innovation is adopted by the mainstream population, and finally slows down as the adopter population reaches saturation. The cumulative adoption pattern is therefore an s-shaped curve, as shown in Figure 4.3, and the adopter distribution represents a normal distribution. All adopters are not identical, and adopters can be classified into innovators, early adopters, early majority, late majority, and laggards based on the time of their adoption. The rate of diffusion also depends on characteristics of the social system such as the presence of opinion leaders (experts whose opinions are valued by others) and change agents (people who influence others’ behaviours).

At the micro (adopter) level, Rogers (1995) [7] suggests that innovation adoption is a process consisting of five stages: one, knowledge : when adopters first learn about an innovation from mass-media or interpersonal channels, two, persuasion : when they are persuaded by prior adopters to try the innovation, three, decision : their decision to accept or reject the innovation, four,: their initial utilisation of the innovation, and five, confirmation : their decision to continue using it to its fullest potential (see Figure 4.4). Five innovation characteristics are presumed to shape adopters’ innovation adoption decisions: one, relative advantage : the expected benefits of an innovation relative to prior innovations, two, compatibility : the extent to which the innovation fits with the adopter’s work habits, beliefs, and values, three, complexity : the extent to which the innovation is difficult to learn and use, four, trialability : the extent to which the innovation can be tested on a trial basis, and five, observability : the extent to which the results of using the innovation can be clearly observed. The last two characteristics have since been dropped from many innovation studies. Complexity is negatively correlated to innovation adoption, while the other four factors are positively correlated. Innovation adoption also depends on personal factors such as the adopter’s risk-taking propensity, education level, cosmopolitanism, and communication influence. Early adopters are venturesome, well educated, and rely more on mass media for information about the innovation, while later adopters rely more on interpersonal sources—such as friends and family—as their primary source of information. IDT has been criticised for having a ‘pro-innovation bias’—that is for presuming that all innovations are beneficial and will be eventually diffused across the entire population, and because it does not allow for inefficient innovations such as fads or fashions to die off quickly without being adopted by the entire population or being replaced by better innovations.

Elaboration likelihood model . Developed by Petty and Cacioppo (1986), [8] the elaboration likelihood model (ELM) is a dual-process theory of attitude formation or change in psychology literature. It explains how individuals can be influenced to change their attitude toward a certain object, event, or behaviour and the relative efficacy of such change strategies. The ELM posits that one’s attitude may be shaped by two ‘routes’ of influence: the central route and the peripheral route, which differ in the amount of thoughtful information processing or ‘elaboration required of people (see Figure 4.5). The central route requires a person to think about issue-related arguments in an informational message and carefully scrutinise the merits and relevance of those arguments, before forming an informed judgment about the target object. In the peripheral route, subjects rely on external ‘cues’ such as number of prior users, endorsements from experts, or likeability of the endorser, rather than on the quality of arguments, in framing their attitude towards the target object. The latter route is less cognitively demanding, and the routes of attitude change are typically operationalised in the ELM using the argument quality and peripheral cues constructs respectively.

Elaboration likelihood model

Whether people will be influenced by the central or peripheral routes depends upon their ability and motivation to elaborate the central merits of an argument. This ability and motivation to elaborate is called elaboration likelihood . People in a state of high elaboration likelihood (high ability and high motivation) are more likely to thoughtfully process the information presented and are therefore more influenced by argument quality, while those in the low elaboration likelihood state are more motivated by peripheral cues. Elaboration likelihood is a situational characteristic and not a personal trait. For instance, a doctor may employ the central route for diagnosing and treating a medical ailment (by virtue of his or her expertise of the subject), but may rely on peripheral cues from auto mechanics to understand the problems with his car. As such, the theory has widespread implications about how to enact attitude change toward new products or ideas and even social change.

General deterrence theory. Two utilitarian philosophers of the eighteenth century, Cesare Beccaria and Jeremy Bentham, formulated general deterrence theory (GDT) as both an explanation of crime and a method for reducing it. GDT examines why certain individuals engage in deviant, anti-social, or criminal behaviours. This theory holds that people are fundamentally rational (for both conforming and deviant behaviours), and that they freely choose deviant behaviours based on a rational cost-benefit calculation. Because people naturally choose utility-maximising behaviours, deviant choices that engender personal gain or pleasure can be controlled by increasing the costs of such behaviours in the form of punishments (countermeasures) as well as increasing the probability of apprehension. Swiftness, severity, and certainty of punishments are the key constructs in GDT.

While classical positivist research in criminology seeks generalised causes of criminal behaviours, such as poverty, lack of education, psychological conditions, and recommends strategies to rehabilitate criminals, such as by providing them job training and medical treatment, GDT focuses on the criminal decision-making process and situational factors that influence that process. Hence, a criminal’s personal situation—such as his personal values, his affluence, and his need for money—and the environmental context—such as how protected the target is, how efficient the local police are, how likely criminals are to be apprehended—play key roles in this decision-making process. The focus of GDT is not how to rehabilitate criminals and avert future criminal behaviours, but how to make criminal activities less attractive and therefore prevent crimes. To that end, ‘target hardening’ such as installing deadbolts and building self-defence skills, legal deterrents such as eliminating parole for certain crimes, ‘three strikes law’ (mandatory incarceration for three offences, even if the offences are minor and not worth imprisonment), and the death penalty, increasing the chances of apprehension using means such as neighbourhood watch programs, special task forces on drugs or gang-related crimes, and increased police patrols, and educational programs such as highly visible notices such as ‘Trespassers will be prosecuted’ are effective in preventing crimes. This theory has interesting implications not only for traditional crimes, but also for contemporary white-collar crimes such as insider trading, software piracy, and illegal sharing of music.

Research  is the systematic investigation of a subject, topic, or question. 

Data  is the information gathered during research.

Fieldwork  is the collection of data in its natural environment.

A white paper is a report or guide that synthesizes a complex topic or question and the state of information and ideas about it.

Scholarship  is, broadly, the activity of a scholar. More specifically though, the term refers to the writings of scholars which result from their research. The scholarship of a field or discipline are the books, articles, etc. which have been written on the field or discipline, or on a specific subject, topic, or question in the field or discipline.  

What is a theory?

A  theory  is the conceptual basis of a subject or area of study. It is the ideas which underlie how something is understood and the framework within which it is studied.  

What is a method?

A  method  is the process or tool used to collect data.

There are three method types: qualitative, quantitative, and historical. Likewise, some research uses mixed methods.

Qualitative research  is interested in the specific. It studies things in their natural settings, attempting to make sense of, or interpret, phenomena in terms of the meanings people bring to them, endeavoring to understand human behavior from the perspective of the individual.

Qualitative methods  collect data through observation. Qualitative methods include text analysis, interviews, focus groups, observation, record keeping, ethnographic research, case study research.

Qualitative data is descriptive. Qualitative data cannot be precisely measured and is, rather, analyzed for patterns and themes using coding. Qualitative data includes narratives, recordings, photographs, oral histories, etc.

Quantitative research  is interested in the general. It studies general laws of behavior and phenomena across different settings and contexts. This type of research endeavors to form conclusions about social phenomena, collecting data to test a theory and ultimately support or reject it.

Quantitative methods  collect data through measuring. Quantitative methods include experiments, surveys, questionnaires, statistical modeling, social networks, and demography.

Quantitative data  is numerical and statistical. It is data that can either be counted or compared on a numeric scale. Quantitative data includes statistical information. 

Historical research  is interested in the past. It reviews and interprets existing data to describe, explain, and understand past actions or events.

Historical methods  collect and analyze existing data and analyze it. Historical methods include text analysis, cultural analysis, visual analysis, archival research.

Historical data  is data which was created in the past. Historical data includes scholarship, records, artifacts.  

A methodology  is the rationale for the research approach and the methods used. It is based upon the theories underlying the field or discipline of the research.

Cultural Studies

Folklore studies, literary studies.

Literary Studies, also called Literary Criticism, is the study of the written works of cultures, societies, groups, and individuals. Literary Studies examines the place of literature in society, and explores how we conceptualize and describe the world and ourselves.  

Literary Theories

There are a number of different theories about literature, why and how it is created. These theories influence how a work of literature is analyzed, interpreted, and understood. Literary Studies most often uses the method of textual analysis.

Cover Art

Linguistic Studies

Linguistics is the study of languages and their structures. Linguistic Studies examines how language is created and constructed, how it functions and is learned, and how we conceptualize and structure our world through our words.   

Language Theories

There are different theories about the creation and purpose of language. Some theories state that language is the result of the nature of society, while others emphasize the role of humans in constructing meaning. Linguistic Studies use methods such as textual analysis, ethnographic research, statistical modeling.

Cover Art

History Studies

History is the study of events, and their related ideas, individuals, and objects. History Studies examines how moments in time are connected, and how we make sense of things that happen.

Historiography  is the study of how historians have interpreted and written about historical events, in essence, how they perceive history itself. Traditionally, a historiography was a name for a history, literally a specific "writing of history".  

History Theories

There are many different theories about if and how events are related to one another, and these theories have influenced how history has been written about over the centuries. History Studies use methods such as textual analysis and archival research.

A related theory to history theories is Memory Theory , which considers how collective and individual memory is created and preserved. Memory Studies examines the ways in which events are recorded and remembered, or, alternatively, forgotten, and how we choose to create and remember (or forget) our past.

Cover Art

Anthropological Studies

Anthropology is the study of human societies, their behaviors and cultures. Anthropological Studies examine how societies are formed and function, and the many aspects which form our identities.

Social Anthropology  examines human behavior. Sometimes this sub-field is combined with Cultural Anthropology as Sociocultural Anthropology.

Cultural Anthropology  examines the cultures, or various beliefs and practices, of societies. Sometimes this sub-field is combined with Social Anthropology as Sociocultural Anthropology.

Physical Anthropology , also called Biological Anthropology, examines the biology of humans and how they interact with their environment.

Linguistic Anthropology  examines the place of language in shaping social life.

Archaeology  examines the material culture, or the objects, of humans. It is considered a sub-field of Anthropology in the United States, and a sub-field of History in other parts of the world.  

Ethnography is the study of a specific society using the methods of observation and immersion, or talking and living with individuals in order to understand them.   

Anthropological Theories

The is a long tradition of theories about how societies organize themselves and how they function. These theories determine how cultural beliefs and practices are understood, in essence, how we understand ourselves and others. Anthropology Studies use methods such as interviews, focus groups, observation, ethnographic research, and record keeping, as well as textual analysis and archival research.

Cover Art

Sociological Studies

Sociology is the study of societies, their behaviors, relationships, and interactions. It examines social order and social changes, trying to understand how and why we organize ourselves and relate to one another.

Historical Sociology   is the study of the behaviors and organization of societies of the past.   

Sociological Theories

There are different theories about how societies are structured and why they act the way they do. Sociological Studies often use the methods of surveys, experiments, ethnographic research, and textual analysis.

Sociological theories are theories about how the mechanics of societies function, whereas  Social Theory  encompasses more broadly theories which explain how societies think and act.

Cover Art

Geography Studies

Geography is the study of land, inhabitants, and natural phenomena. It examines the relationship between humans and their environment, and helps us to understand our relationship with the world. 

Human Geography  examines humans and their communities, and their relationships with place, space, and environment.

Physical Geography  examines the processes and patterns of environments, such as their atmosphere, hydrosphere, biosphere, and geosphere.

Cartography  is both the study of and the science and art of map-making. It reveals how we view and conceptualize the world and our relationship to it and to others.   

Geography Theories

There are a number of theories as to the relationship between humans and their environments, many of which are shared with the fields of Anthropology and Sociology. Geography Studies use a variety of research methods, including interviews, surveys, observation, and GIS or spatial analysis.

Cover Art

Cultural Studies is the study and analysis of culture. It is a cross-disciplinary field which examines the various aspects of a society, in order to understand how we form our identities. 

Culture  is the ideas, behaviors, customs, and objects of a region, society, group, or individual. 

Material culture   are the physical objects of a culture, such as tools, domestic objects, religious objects, works of art.  

Cultural Theories

Cultural theories draw upon theories in a variety of fields, including literary theories, semiotics, history theories, anthropological theories, social theories, museum studies, art history, and media studies. Cultural theories influence how we analyze and interpret the culture of societies. Cultural Studies tends to use methods such as interviews, observation, ethnographic research, record keeping, archival research, textual analysis, visual analysis.

Cover Art

Folklore Studies, also known as Folkloristics, is the study of the expressions of culture, particularly the practices and products of a society. Folklore Studies examines the things we make to understand how they make us.

Folklore  has been traditionally considered, narrowly, as the oral tales of a society. More broadly, the term refers to all aspects of a culture – beliefs, traditions, norms, behaviors, language, literature, jokes, music, art, foodways, tools, objects, etc.  

Folklore Theories

A number of theories have emerged over the years about how societies create themselves, and these theories influence how we view and understand the things which societies create. Folklore Studies use methods such as interviews, focus groups, observation, ethnographic research, and record keeping, as well as textual analysis, visual analysis and archival research.

Arts Studies

The arts are a range of disciplines which study, create, and engage with human expression. The arts include,

  • Architecture -- Design
  • Visual Arts -- Drawing, Painting, Illustration, Sculpting, Ceramics, Photography, Film
  • Literary Arts -- Fiction, Drama, Poetry, Creative Writing, Storytelling
  • Performance Arts -- Music, Dance, Theatre
  • Textile Arts -- Fashion
  • Craft -- Weaving, Woodwork, Paperwork, Glasswork, Jewelry-making
  • Culinary Arts -- Cooking, Baking, Chocolate-making, Brewing, Wine-making
  • Art History and Criticism

The arts are a collection of areas of studies which combine technical skills and creativity to produce objects which convey human experience.

Architecture  is the study and design of structures. It examines both the utilitarian and the sociological aspects of space, and the relationship between constructed space and humans. 

Art History  is the study and analysis of visual arts. 

Musicology  is the study and analysis of music.

Performance   is the study and the practice of art is time and space. 

Film & Media Studies  is the study of art which employs technologies.   

Art Theories

There are as many theories about the arts as there are areas of arts. These theories affect how we understand the identity and the agency of the artist, the meaning of the art, and the relationship between the art and society. Arts fields often employ textual and visual analysis research methods, as well as observation and experimentation. 

Cover Art

Folklorists study people's lives and thus they are responsible to preserve and protect culture. Folklorists are professionals and researchers and thus they have a responsibility to the field to uphold standards of behavior and work. Finally, folklorists interact with individuals and are responsible to uphold human rights. Though there is little direct legislation governing folklore studies, there are numerous laws concerning human rights and information, as well as professional standards in the field of cultural heritage preservation.

Background:

Grounded theory is a well-known methodology employed in many research studies. Qualitative and quantitative data generation techniques can be used in a grounded theory study. Grounded theory sets out to discover or construct theory from data, systematically obtained and analysed using comparative analysis. While grounded theory is inherently flexible, it is a complex methodology. Thus, novice researchers strive to understand the discourse and the practical application of grounded theory concepts and processes.

The aim of this article is to provide a contemporary research framework suitable to inform a grounded theory study.

This article provides an overview of grounded theory illustrated through a graphic representation of the processes and methods employed in conducting research using this methodology. The framework is presented as a diagrammatic representation of a research design and acts as a visual guide for the novice grounded theory researcher.

Discussion:

As grounded theory is not a linear process, the framework illustrates the interplay between the essential grounded theory methods and iterative and comparative actions involved. Each of the essential methods and processes that underpin grounded theory are defined in this article.

Conclusion:

Rather than an engagement in philosophical discussion or a debate of the different genres that can be used in grounded theory, this article illustrates how a framework for a research study design can be used to guide and inform the novice nurse researcher undertaking a study using grounded theory. Research findings and recommendations can contribute to policy or knowledge development, service provision and can reform thinking to initiate change in the substantive area of inquiry.

Introduction

The aim of all research is to advance, refine and expand a body of knowledge, establish facts and/or reach new conclusions using systematic inquiry and disciplined methods. 1 The research design is the plan or strategy researchers use to answer the research question, which is underpinned by philosophy, methodology and methods. 2 Birks 3 defines philosophy as ‘a view of the world encompassing the questions and mechanisms for finding answers that inform that view’ (p. 18). Researchers reflect their philosophical beliefs and interpretations of the world prior to commencing research. Methodology is the research design that shapes the selection of, and use of, particular data generation and analysis methods to answer the research question. 4 While a distinction between positivist research and interpretivist research occurs at the paradigm level, each methodology has explicit criteria for the collection, analysis and interpretation of data. 2 Grounded theory (GT) is a structured, yet flexible methodology. This methodology is appropriate when little is known about a phenomenon; the aim being to produce or construct an explanatory theory that uncovers a process inherent to the substantive area of inquiry. 5 – 7 One of the defining characteristics of GT is that it aims to generate theory that is grounded in the data. The following section provides an overview of GT – the history, main genres and essential methods and processes employed in the conduct of a GT study. This summary provides a foundation for a framework to demonstrate the interplay between the methods and processes inherent in a GT study as presented in the sections that follow.

Glaser and Strauss are recognised as the founders of grounded theory. Strauss was conversant in symbolic interactionism and Glaser in descriptive statistics. 8 – 10 Glaser and Strauss originally worked together in a study examining the experience of terminally ill patients who had differing knowledge of their health status. Some of these suspected they were dying and tried to confirm or disconfirm their suspicions. Others tried to understand by interpreting treatment by care providers and family members. Glaser and Strauss examined how the patients dealt with the knowledge they were dying and the reactions of healthcare staff caring for these patients. Throughout this collaboration, Glaser and Strauss questioned the appropriateness of using a scientific method of verification for this study. During this investigation, they developed the constant comparative method, a key element of grounded theory, while generating a theory of dying first described in Awareness of Dying (1965). The constant comparative method is deemed an original way of organising and analysing qualitative data.

Glaser and Strauss subsequently went on to write The Discovery of Grounded Theory: Strategies for Qualitative Research (1967). This seminal work explained how theory could be generated from data inductively. This process challenged the traditional method of testing or refining theory through deductive testing. Grounded theory provided an outlook that questioned the view of the time that quantitative methodology is the only valid, unbiased way to determine truths about the world. 11 Glaser and Strauss 5 challenged the belief that qualitative research lacked rigour and detailed the method of comparative analysis that enables the generation of theory. After publishing The Discovery of Grounded Theory , Strauss and Glaser went on to write independently, expressing divergent viewpoints in the application of grounded theory methods.

Glaser produced his book Theoretical Sensitivity (1978) and Strauss went on to publish Qualitative Analysis for Social Scientists (1987). Strauss and Corbin’s 12 publication Basics of Qualitative Research: Grounded Theory Procedures and Techniques resulted in a rebuttal by Glaser 13 over their application of grounded theory methods. However, philosophical perspectives have changed since Glaser’s positivist version and Strauss and Corbin’s post-positivism stance. 14 Grounded theory has since seen the emergence of additional philosophical perspectives that have influenced a change in methodological development over time. 15

Subsequent generations of grounded theorists have positioned themselves along a philosophical continuum, from Strauss and Corbin’s 12 theoretical perspective of symbolic interactionism, through to Charmaz’s 16 constructivist perspective. However, understanding how to position oneself philosophically can challenge novice researchers. Birks and Mills 6 provide a contemporary understanding of GT in their book Grounded theory: A Practical Guide. These Australian researchers have written in a way that appeals to the novice researcher. It is the contemporary writing, the way Birks and Mills present a non-partisan approach to GT that support the novice researcher to understand the philosophical and methodological concepts integral in conducting research. The development of GT is important to understand prior to selecting an approach that aligns with the researcher’s philosophical position and the purpose of the research study. As the research progresses, seminal texts are referred back to time and again as understanding of concepts increases, much like the iterative processes inherent in the conduct of a GT study.

Genres: traditional, evolved and constructivist grounded theory

Grounded theory has several distinct methodological genres: traditional GT associated with Glaser; evolved GT associated with Strauss, Corbin and Clarke; and constructivist GT associated with Charmaz. 6 , 17 Each variant is an extension and development of the original GT by Glaser and Strauss. The first of these genres is known as traditional or classic GT. Glaser 18 acknowledged that the goal of traditional GT is to generate a conceptual theory that accounts for a pattern of behaviour that is relevant and problematic for those involved. The second genre, evolved GT, is founded on symbolic interactionism and stems from work associated with Strauss, Corbin and Clarke. Symbolic interactionism is a sociological perspective that relies on the symbolic meaning people ascribe to the processes of social interaction. Symbolic interactionism addresses the subjective meaning people place on objects, behaviours or events based on what they believe is true. 19 , 20 Constructivist GT, the third genre developed and explicated by Charmaz, a symbolic interactionist, has its roots in constructivism. 8 , 16 Constructivist GT’s methodological underpinnings focus on how participants’ construct meaning in relation to the area of inquiry. 16 A constructivist co-constructs experience and meanings with participants. 21 While there are commonalities across all genres of GT, there are factors that distinguish differences between the approaches including the philosophical position of the researcher; the use of literature; and the approach to coding, analysis and theory development. Following on from Glaser and Strauss, several versions of GT have ensued.

Grounded theory represents both a method of inquiry and a resultant product of that inquiry. 7 , 22 Glaser and Holton 23 define GT as ‘a set of integrated conceptual hypotheses systematically generated to produce an inductive theory about a substantive area’ (p. 43). Strauss and Corbin 24 define GT as ‘theory that was derived from data, systematically gathered and analysed through the research process’ (p. 12). The researcher ‘begins with an area of study and allows the theory to emerge from the data’ (p. 12). Charmaz 16 defines GT as ‘a method of conducting qualitative research that focuses on creating conceptual frameworks or theories through building inductive analysis from the data’ (p. 187). However, Birks and Mills 6 refer to GT as a process by which theory is generated from the analysis of data. Theory is not discovered; rather, theory is constructed by the researcher who views the world through their own particular lens.

Research process

Before commencing any research study, the researcher must have a solid understanding of the research process. A well-developed outline of the study and an understanding of the important considerations in designing and undertaking a GT study are essential if the goals of the research are to be achieved. While it is important to have an understanding of how a methodology has developed, in order to move forward with research, a novice can align with a grounded theorist and follow an approach to GT. Using a framework to inform a research design can be a useful modus operandi.

The following section provides insight into the process of undertaking a GT research study. Figure 1 is a framework that summarises the interplay and movement between methods and processes that underpin the generation of a GT. As can be seen from this framework, and as detailed in the discussion that follows, the process of doing a GT research study is not linear, rather it is iterative and recursive.

Research design framework: summary of the interplay between the essential grounded theory methods and processes.

Grounded theory research involves the meticulous application of specific methods and processes. Methods are ‘systematic modes, procedures or tools used for collection and analysis of data’. 25 While GT studies can commence with a variety of sampling techniques, many commence with purposive sampling, followed by concurrent data generation and/or collection and data analysis, through various stages of coding, undertaken in conjunction with constant comparative analysis, theoretical sampling and memoing. Theoretical sampling is employed until theoretical saturation is reached. These methods and processes create an unfolding, iterative system of actions and interactions inherent in GT. 6 , 16 The methods interconnect and inform the recurrent elements in the research process as shown by the directional flow of the arrows and the encompassing brackets in Figure 1 . The framework denotes the process is both iterative and dynamic and is not one directional. Grounded theory methods are discussed in the following section.

Purposive sampling

As presented in Figure 1 , initial purposive sampling directs the collection and/or generation of data. Researchers purposively select participants and/or data sources that can answer the research question. 5 , 7 , 16 , 21 Concurrent data generation and/or data collection and analysis is fundamental to GT research design. 6 The researcher collects, codes and analyses this initial data before further data collection/generation is undertaken. Purposeful sampling provides the initial data that the researcher analyses. As will be discussed, theoretical sampling then commences from the codes and categories developed from the first data set. Theoretical sampling is used to identify and follow clues from the analysis, fill gaps, clarify uncertainties, check hunches and test interpretations as the study progresses.

Constant comparative analysis

Constant comparative analysis is an analytical process used in GT for coding and category development. This process commences with the first data generated or collected and pervades the research process as presented in Figure 1 . Incidents are identified in the data and coded. 6 The initial stage of analysis compares incident to incident in each code. Initial codes are then compared to other codes. Codes are then collapsed into categories. This process means the researcher will compare incidents in a category with previous incidents, in both the same and different categories. 5 Future codes are compared and categories are compared with other categories. New data is then compared with data obtained earlier during the analysis phases. This iterative process involves inductive and deductive thinking. 16 Inductive, deductive and abductive reasoning can also be used in data analysis. 26

Constant comparative analysis generates increasingly more abstract concepts and theories through inductive processes. 16 In addition, abduction, defined as ‘a form of reasoning that begins with an examination of the data and the formation of a number of hypotheses that are then proved or disproved during the process of analysis … aids inductive conceptualization’. 6 Theoretical sampling coupled with constant comparative analysis raises the conceptual levels of data analysis and directs ongoing data collection or generation. 6

The constant comparative technique is used to find consistencies and differences, with the aim of continually refining concepts and theoretically relevant categories. This continual comparative iterative process that encompasses GT research sets it apart from a purely descriptive analysis. 8

Memo writing is an analytic process considered essential ‘in ensuring quality in grounded theory’. 6 Stern 27 offers the analogy that if data are the building blocks of the developing theory, then memos are the ‘mortar’ (p. 119). Memos are the storehouse of ideas generated and documented through interacting with data. 28 Thus, memos are reflective interpretive pieces that build a historic audit trail to document ideas, events and the thought processes inherent in the research process and developing thinking of the analyst. 6 Memos provide detailed records of the researchers’ thoughts, feelings and intuitive contemplations. 6

Lempert 29 considers memo writing crucial as memos prompt researchers to analyse and code data and develop codes into categories early in the coding process. Memos detail why and how decisions made related to sampling, coding, collapsing of codes, making of new codes, separating codes, producing a category and identifying relationships abstracted to a higher level of analysis. 6 Thus, memos are informal analytic notes about the data and the theoretical connections between categories. 23 Memoing is an ongoing activity that builds intellectual assets, fosters analytic momentum and informs the GT findings. 6 , 10

Generating/collecting data

A hallmark of GT is concurrent data generation/collection and analysis. In GT, researchers may utilise both qualitative and quantitative data as espoused by Glaser’s dictum; ‘all is data’. 30 While interviews are a common method of generating data, data sources can include focus groups, questionnaires, surveys, transcripts, letters, government reports, documents, grey literature, music, artefacts, videos, blogs and memos. 9 Elicited data are produced by participants in response to, or directed by, the researcher whereas extant data includes data that is already available such as documents and published literature. 6 , 31 While this is one interpretation of how elicited data are generated, other approaches to grounded theory recognise the agency of participants in the co-construction of data with the researcher. The relationship the researcher has with the data, how it is generated and collected, will determine the value it contributes to the development of the final GT. 6 The significance of this relationship extends into data analysis conducted by the researcher through the various stages of coding.

Coding is an analytical process used to identify concepts, similarities and conceptual reoccurrences in data. Coding is the pivotal link between collecting or generating data and developing a theory that explains the data. Charmaz 10 posits,

codes rely on interaction between researchers and their data. Codes consist of short labels that we construct as we interact with the data. Something kinaesthetic occurs when we are coding; we are mentally and physically active in the process. (p. 5)

In GT, coding can be categorised into iterative phases. Traditional, evolved and constructivist GT genres use different terminology to explain each coding phase ( Table 1 ).

Adapted from Birks and Mills. 6

Coding terminology in evolved GT refers to open (a procedure for developing categories of information), axial (an advanced procedure for interconnecting the categories) and selective coding (procedure for building a storyline from core codes that connects the categories), producing a discursive set of theoretical propositions. 6 , 12 , 32 Constructivist grounded theorists refer to initial, focused and theoretical coding. 9 Birks and Mills 6 use the terms initial, intermediate and advanced coding that link to low, medium and high-level conceptual analysis and development. The coding terms devised by Birks and Mills 6 were used for Figure 1 ; however, these can be altered to reflect the coding terminology used in the respective GT genres selected by the researcher.

Initial coding

Initial coding of data is the preliminary step in GT data analysis. 6 , 9 The purpose of initial coding is to start the process of fracturing the data to compare incident to incident and to look for similarities and differences in beginning patterns in the data. In initial coding, the researcher inductively generates as many codes as possible from early data. 16 Important words or groups of words are identified and labelled. In GT, codes identify social and psychological processes and actions as opposed to themes. Charmaz 16 emphasises keeping codes as similar to the data as possible and advocates embedding actions in the codes in an iterative coding process. Saldaña 33 agrees that codes that denote action, which he calls process codes, can be used interchangeably with gerunds (verbs ending in ing ). In vivo codes are often verbatim quotes from the participants’ words and are often used as the labels to capture the participant’s words as representative of a broader concept or process in the data. 6 Table 1 reflects variation in the terminology of codes used by grounded theorists.

Initial coding categorises and assigns meaning to the data, comparing incident-to-incident, labelling beginning patterns and beginning to look for comparisons between the codes. During initial coding, it is important to ask ‘what is this data a study of’. 18 What does the data assume, ‘suggest’ or ‘pronounce’ and ‘from whose point of view’ does this data come, whom does it represent or whose thoughts are they?. 16 What collectively might it represent? The process of documenting reactions, emotions and related actions enables researchers to explore, challenge and intensify their sensitivity to the data. 34 Early coding assists the researcher to identify the direction for further data gathering. After initial analysis, theoretical sampling is employed to direct collection of additional data that will inform the ‘developing theory’. 9 Initial coding advances into intermediate coding once categories begin to develop.

Theoretical sampling

The purpose of theoretical sampling is to allow the researcher to follow leads in the data by sampling new participants or material that provides relevant information. As depicted in Figure 1 , theoretical sampling is central to GT design, aids the evolving theory 5 , 7 , 16 and ensures the final developed theory is grounded in the data. 9 Theoretical sampling in GT is for the development of a theoretical category, as opposed to sampling for population representation. 10 Novice researchers need to acknowledge this difference if they are to achieve congruence within the methodology. Birks and Mills 6 define theoretical sampling as ‘the process of identifying and pursuing clues that arise during analysis in a grounded theory study’ (p. 68). During this process, additional information is sought to saturate categories under development. The analysis identifies relationships, highlights gaps in the existing data set and may reveal insight into what is not yet known. The exemplars in Box 1 highlight how theoretical sampling led to the inclusion of further data.

Examples of theoretical sampling.

In Chamberlain-Salaun GT study, ‘the initial purposive round of concurrent data generation and analysis generated codes around concepts of physical disability and how a person’s health condition influences the way experts interact with consumers. Based on initial codes and concepts the researcher decided to theoretically sample people with disabilities and or carers/parents of children with disabilities to pursue the concepts further’ (p. 77).
In Edwards grounded theory study, theoretical sampling led to the inclusion of the partners of women who had presented to the emergency department. ‘In one interview a woman spoke of being aware that the ED staff had not acknowledged her partner. This statement led me to ask other women during their interviews if they had similar experiences, and ultimately to interview the partners to gain their perspectives. The study originally intended to only focus on the women and the nursing staff who provided the care’ (p. 50).

Thus, theoretical sampling is used to focus and generate data to feed the iterative process of continual comparative analysis of the data. 6

Intermediate coding

Intermediate coding, identifying a core category, theoretical data saturation, constant comparative analysis, theoretical sensitivity and memoing occur in the next phase of the GT process. 6 Intermediate coding builds on the initial coding phase. Where initial coding fractures the data, intermediate coding begins to transform basic data into more abstract concepts allowing the theory to emerge from the data. During this analytic stage, a process of reviewing categories and identifying which ones, if any, can be subsumed beneath other categories occurs and the properties or dimension of the developed categories are refined. Properties refer to the characteristics that are common to all the concepts in the category and dimensions are the variations of a property. 37

At this stage, a core category starts to become evident as developed categories form around a core concept; relationships are identified between categories and the analysis is refined. Birks and Mills 6 affirm that diagramming can aid analysis in the intermediate coding phase. Grounded theorists interact closely with the data during this phase, continually reassessing meaning to ascertain ‘what is really going on’ in the data. 30 Theoretical saturation ensues when new data analysis does not provide additional material to existing theoretical categories, and the categories are sufficiently explained. 6

Advanced coding

Birks and Mills 6 described advanced coding as the ‘techniques used to facilitate integration of the final grounded theory’ (p. 177). These authors promote storyline technique (described in the following section) and theoretical coding as strategies for advancing analysis and theoretical integration. Advanced coding is essential to produce a theory that is grounded in the data and has explanatory power. 6 During the advanced coding phase, concepts that reach the stage of categories will be abstract, representing stories of many, reduced into highly conceptual terms. The findings are presented as a set of interrelated concepts as opposed to presenting themes. 28 Explanatory statements detail the relationships between categories and the central core category. 28

Storyline is a tool that can be used for theoretical integration. Birks and Mills 6 define storyline as ‘a strategy for facilitating integration, construction, formulation, and presentation of research findings through the production of a coherent grounded theory’ (p. 180). Storyline technique is first proposed with limited attention in Basics of Qualitative Research by Strauss and Corbin 12 and further developed by Birks et al. 38 as a tool for theoretical integration. The storyline is the conceptualisation of the core category. 6 This procedure builds a story that connects the categories and produces a discursive set of theoretical propositions. 24 Birks and Mills 6 contend that storyline can be ‘used to produce a comprehensive rendering of your grounded theory’ (p. 118). Birks et al. 38 had earlier concluded, ‘storyline enhances the development, presentation and comprehension of the outcomes of grounded theory research’ (p. 405). Once the storyline is developed, the GT is finalised using theoretical codes that ‘provide a framework for enhancing the explanatory power of the storyline and its potential as theory’. 6 Thus, storyline is the explication of the theory.

Theoretical coding occurs as the final culminating stage towards achieving a GT. 39 , 40 The purpose of theoretical coding is to integrate the substantive theory. 41 Saldaña 40 states, ‘theoretical coding integrates and synthesises the categories derived from coding and analysis to now create a theory’ (p. 224). Initial coding fractures the data while theoretical codes ‘weave the fractured story back together again into an organized whole theory’. 18 Advanced coding that integrates extant theory adds further explanatory power to the findings. 6 The examples in Box 2 describe the use of storyline as a technique.

Writing the storyline.

Baldwin describes in her GT study how ‘the process of writing the storyline allowed in-depth descriptions of the categories, and discussion of how the categories of (i) , (ii) and (iii) fit together to form the final theory: ’ (pp. 125–126). ‘The use of storyline as part of the finalisation of the theory from the data ensured that the final theory was grounded in the data’ (p. 201).
In Chamberlain-Salaun GT study, writing the storyline enabled the identification of ‘gaps in the developing theory and to clarify categories and concepts. To address the gaps the researcher iteratively returned to the data and to the field and refine the storyline. Once the storyline was developed raw data was incorporated to support the story in much the same way as dialogue is included in a storybook or novel’.

Theoretical sensitivity

As presented in Figure 1 , theoretical sensitivity encompasses the entire research process. Glaser and Strauss 5 initially described the term theoretical sensitivity in The Discovery of Grounded Theory. Theoretical sensitivity is the ability to know when you identify a data segment that is important to your theory. While Strauss and Corbin 12 describe theoretical sensitivity as the insight into what is meaningful and of significance in the data for theory development, Birks and Mills 6 define theoretical sensitivity as ‘the ability to recognise and extract from the data elements that have relevance for the emerging theory’ (p. 181). Conducting GT research requires a balance between keeping an open mind and the ability to identify elements of theoretical significance during data generation and/or collection and data analysis. 6

Several analytic tools and techniques can be used to enhance theoretical sensitivity and increase the grounded theorist’s sensitivity to theoretical constructs in the data. 28 Birks and Mills 6 state, ‘as a grounded theorist becomes immersed in the data, their level of theoretical sensitivity to analytic possibilities will increase’ (p. 12). Developing sensitivity as a grounded theorist and the application of theoretical sensitivity throughout the research process allows the analytical focus to be directed towards theory development and ultimately result in an integrated and abstract GT. 6 The example in Box 3 highlights how analytic tools are employed to increase theoretical sensitivity.

Theoretical sensitivity.

Hoare et al. described how the lead author ‘ in pursuit of heightened theoretical sensitivity in a grounded theory study of information use by nurses working in general practice in New Zealand’. The article described the analytic tools the researcher used ‘to increase theoretical sensitivity’ which included ‘reading the literature, open coding, category building, reflecting in memos followed by doubling back on data collection once further lines of inquiry are opened up’. The article offers ‘an example of how analytical tools are employed to theoretically sample emerging concepts’ (pp. 240–241).

The grounded theory

The meticulous application of essential GT methods refines the analysis resulting in the generation of an integrated, comprehensive GT that explains a process relating to a particular phenomenon. 6 The results of a GT study are communicated as a set of concepts, related to each other in an interrelated whole, and expressed in the production of a substantive theory. 5 , 7 , 16 A substantive theory is a theoretical interpretation or explanation of a studied phenomenon 6 , 17 Thus, the hallmark of grounded theory is the generation of theory ‘abstracted from, or grounded in, data generated and collected by the researcher’. 6 However, to ensure quality in research requires the application of rigour throughout the research process.

Quality and rigour

The quality of a grounded theory can be related to three distinct areas underpinned by (1) the researcher’s expertise, knowledge and research skills; (2) methodological congruence with the research question; and (3) procedural precision in the use of methods. 6 Methodological congruence is substantiated when the philosophical position of the researcher is congruent with the research question and the methodological approach selected. 6 Data collection or generation and analytical conceptualisation need to be rigorous throughout the research process to secure excellence in the final grounded theory. 44

Procedural precision requires careful attention to maintaining a detailed audit trail, data management strategies and demonstrable procedural logic recorded using memos. 6 Organisation and management of research data, memos and literature can be assisted using software programs such as NVivo. An audit trail of decision-making, changes in the direction of the research and the rationale for decisions made are essential to ensure rigour in the final grounded theory. 6

This article offers a framework to assist novice researchers visualise the iterative processes that underpin a GT study. The fundamental process and methods used to generate an integrated grounded theory have been described. Novice researchers can adapt the framework presented to inform and guide the design of a GT study. This framework provides a useful guide to visualise the interplay between the methods and processes inherent in conducting GT. Research conducted ethically and with meticulous attention to process will ensure quality research outcomes that have relevance at the practice level.

How to Use Data Triangulation in Qualitative Research

' src=

In qualitative research, data triangulation means approaching a question from multiple perspectives. 

It involves using more than one data source or method to investigate a theory or corroborate a finding. 

For something with such a mathematical-sounding name, it’s a pretty simple concept. But it’s a powerful one, too. Ask a group of five boaters why their watercraft sank in the sea and you’ll get five slightly different stories. Each individual tale holds the bias of its teller. Taken together, though, the individual accounts form a deeper and more accurate picture of what went wrong.

This logic applies to qualitative research. Since qualitative data isn’t as cut-and-dry as quantitative data , you need more than one perspective, data type, and method to shore it up. 

With triangulation, you give the results a stronger platform to stand on. 

When to Use Data Triangulation with Qualitative Data

If you ask me, there’s never a bad time to do data triangulation when you’re working with qualitative data. 

From a researcher’s point of view, triangulation can help you verify key details and strengthen your findings—and your argument.

And if you’re someone who uses qualitative data to inform your business decisions, gathering data from multiple sources is smart. It can help you make critical choices with a level of confidence you wouldn’t (and shouldn’t) have if you relied on just one source. 

In a 2014 journal article published in the Oncology Nursing Forum titled, “ The use of triangulation in qualitative research ,” authors Nancy Carter, et al., lay out two views of data triangulation. 

They argue that it’s both “the use of multiple methods or data sources in qualitative research to develop a comprehensive understanding of phenomena” and “a qualitative research strategy to test validity through the convergence of information from different sources.”

Put into simpler words, qualitative data triangulation helps us:

  • Gain a fuller understanding of a research topic or argument
  • Put our research to the test by comparing and contrasting it with different sources on the same topic

Well-rounded arguments benefit everyone, all the time. 

So if you’ve been on the fence about whether to draw sources from more than one place or use more than one method in your research, consider this your sign. 

Do it. 

How to Do Qualitative Data Triangulation 

Before you begin running qualitative data triangulation, it’s helpful to know the four types, as outlined by Carter et al.:

  • Method triangulation: Using two or more methods to gather data
  • Investigator triangulation: Relying on the involvement of more than one researcher to collect or analyze the data
  • Theory triangulation: Analyzing the data using different theoretical perspectives 
  • Data source triangulation: Drawing information from multiple data sources, including those from different times, places, and people

Knowing which type of triangulation to focus on can be tricky. 

We’ll explore each type in more detail and suggest questions to ask yourself when you’re tackling the beginning of the triangulation process. 

Method triangulation

Method triangulation means using a variety of research methods to study the same topic. In qualitative research, the most common data-gathering methods are:

  • Focus groups
  • Observation
  • Open-ended surveys or questionnaires

So, in qualitative research, method triangulation means gathering data using at least two of these methods. 

But method triangulation can also mean looping in non-qualitative forms of data collection, like demographic information or responses to closed-question (yes-or-no and/or multiple-choice) surveys. Since we’re focusing on qualitative data here, though, we’ll save mixed-method triangulation for another day.

Right now, our lens is firmly focused on qualitative research.

Use method triangulation when:  

  • Leaning heavily on one method will only give you a partial view of your research question or topic. Say you’re sending out a survey to find what people find most stressful about in-person grocery shopping. You get some interesting answers, but you want to dig deeper. You decide to send a group of shoppers into a store with cash and a grocery list to observe their lived, in-the-moment experiences. Along with the survey responses, you now have a more complete picture of common grocery-shopping stressors. 
  • You need to cross-validate findings from different methods . Imagine you’re doing in-depth interviews with employees to understand their job satisfaction. At the same time, you want to see if these self-reported experiences align with behaviors you can observe during the workday. You decide to pair the interviews with direct workplace observations. The goal? To see whether the employees’ daily actions match their satisfaction levels. If you see any inconsistencies, you can go over them with the interviewee for a more accurate picture of their experience. 

Investigator Triangulation 

The goal of investigator triangulation is to have more than one researcher (or team of researchers) analyze the same set of data. Like a peer review for a scholarly journal article, investigator triangulation helps reduce bias. This, in turn, strengthens the credibility of your research.

But you have to be careful not to invite researchers with your same opinions and biases to participate in this type of triangulation. You don’t want them to confirm everything you’ve researched. You want them to read it line by line, grappling with the information and pushing you to see it in a new light.

Reach out to people in different—but related—fields. Invite them to collaborate by analyzing your research and engaging with it from their own viewpoints. Listen carefully to what they have to say—don’t just dismiss it because you don’t see things the same way.

This is how you’ll get the most well-rounded analysis of your qualitative research.

Use investigator triangulation when: 

  • The research involves subjective interpretations or complex topics. If your data could be viewed differently depending on the researcher’s perspective, then you need fresh eyes to look at it. If you’re studying how patients perceive care in a hospital setting, for example, one researcher might focus on emotional aspects like empathy. Another might not consider this at all and instead focus on how efficient the care is. Both perspectives are important to your research.
  • The topic is sensitive or controversial. If you feel like your data is going to ignite a firestorm of controversy, you need extra eyes. Lots of them. The more scrutiny before the data gets published or used to inform a decision, the better. You want minimal personal bias—and maximum credibility .

Theory Triangulation 

With theory triangulation, you aren’t using different data collection methods or bringing in researchers with unique viewpoints. 

Instead, you’re changing the lens through which you see the data.

This approach challenges researchers to set aside their original theories for analyzing information. It invites them to use at least one additional, theoretical perspective when they sit down to interpret the data.

Researchers usually use theory triangulation when their topic spans more than one discipline. If you were studying human grocery shopping behavior, for instance, you could analyze the results through three lenses:

  • Psychological : Study how individual decision-making processes, emotions, and cognitive biases affect shopping choices. Does impulse buying play a role? What about decision fatigue?
  • Sociological : Examine the influence of social factors. Do cultural norms, peer pressure, or family dynamics affect shopping habits? Does social class impact purchasing behavior? If so, how?
  • Economic : Analyze the shoppers’ behavior through the lens of cost-benefit analysis, budget limits, and price sensitivity. How do incentives like discounts or promotions influence purchases—or not?

Basically, theory triangulation pushes you to consider things from viewpoints you hadn’t before. And it can make the results a lot meatier than if you relied on a single theory.

Use theory triangulation when: 

  • You are studying a complex topic that could use a few different theoretical perspectives to be understood. Say you’re looking at the factors behind employee motivation. You might use psychological theories like Maslow’s Hierarchy of Needs to explore intrinsic motivators. Next, you could use economic theories to study how external factors like financial incentives influence performance.
  • You want to compare or test the validity of multiple theories to see which framework best fits your data. Let’s imagine you’re studying educational outcomes. You could compare Constructivist Theory (focused on how students build knowledge) with Behaviorist Theory (focused on reinforcement and discipline), to see which one better explains student success.  

Data Source Triangulation 

With data source triangulation, your goal is to gather data from at least two sources, but probably more than that.

What does this look like in qualitative research?

It might mean gathering data from: 

  • Archival records
  • Textual analysis of policy/legal documents
  • Social media content
  • News articles, blogs, and other media content
  • The comments section of any forum, website, or blog
  • Case studies
  • Literature and artwork

The point of data source triangulation is to study one topic using these diverse data sources. (If you want to pull from quantitative data sources like web analytics and public databases, you can do that too.)

This is essentially another way to study your research question from multiple perspectives. But instead of a group of different researchers or a set of theories from multiple disciplines, those differing data sources are the other perspectives.

Use data source triangulation when:  

  • You need to collect data from different sources to gather perspectives on a topic—without direct interaction. For example, say you’re studying public perceptions of climate change. You want to capture the raw, unfiltered feelings and opinions behind this fraught topic. What better place to go than social media discussions, news articles (and their comments sections), and government reports? You’ll get tons of rich, probably brutally honest data without ever making your presence as a researcher known. 

You want to validate findings across existing qualitative data sources. Let’s say you’re studying stigmas on mental health issues. You’ve already used methodological triangulation to gather qualitative data from interviews and surveys. Now, you want to compare this data with themes from online forums, blog posts, and personal memoirs. The data found in these sources can help validate your findings—or bring up new questions and interesting discrepancies to explore.

Can AI talk us out of conspiracy theories?

MIT Sloan Office of Communications

Sep 13, 2024

New MIT Sloan research shows that conversations with large language models can successfully reduce belief in conspiracy theories.

CAMBRIDGE, Mass., September 12, 2024 – Have you ever tried to convince a conspiracy theorist that the moon landing wasn’t staged? You likely didn’t succeed, but ChatGPT might have better luck, according to research by  MIT Sloan School of Management professor David Rand and American University professor of psychology  Thomas Costello , who conducted the research during his postdoctoral position at MIT Sloan.

In a new paper “ Durably reducing conspiracy beliefs through dialogues with AI ” published in  Science,  the researchers show that large language models can effectively reduce individuals’ beliefs in conspiracy theories — and that these reductions last for at least 2 months — a finding that offers new insights into the psychological mechanisms behind the phenomenon as well as potential tools to fight the spread of conspiracies.  Going down the rabbit hole

Conspiracy theories — beliefs that certain events are the result of secret plots by influential actors — have long been a subject of fascination and concern. Their persistence in the face of counter-evidence has led to the conclusion that they fulfill deep-seated psychological needs, rendering them impervious to facts and logic. According to this conventional wisdom, once someone “ falls down the rabbit hole ,” it’s virtually impossible to pull them back out.

But for Rand, Costello, and their co-author professor  Gordon Pennycook from Cornell University, who have conducted extensive research on the spread and uptake of misinformation, that conclusion didn’t ring true. Instead, they suspected a simpler explanation was at play.

“We wondered if it was possible that people simply hadn’t been exposed to compelling evidence disproving their theories,” Rand explained. “Conspiracy theories come in many varieties — the specifics of the theory and the arguments used to support it differ from believer to believer. So if you are trying to disprove the conspiracy but haven’t heard these particular arguments, you won’t be prepared to rebut them.”

Effectively debunking conspiracy theories, in other words, would require two things: personalized arguments and access to vast quantities of information — both now readily available through generative AI.

Conspiracy conversations with GPT4

To test their theory, Costello, Pennycook, and Rand harnessed the power of GPT-4 Turbo, OpenAI’s most advanced large language model, to engage over 2,000 conspiracy believers in personalized, evidence-based dialogues.

The study employed a unique methodology that allowed for deep engagement with participants' individual beliefs. Participants were first asked to identify and describe a conspiracy theory they believed in using their own words, along with the evidence supporting their belief.

GPT-4 Turbo then used this information to generate a personalized summary of the participant's belief and initiate a dialogue. The AI was instructed to persuade users that their beliefs were untrue, adapting its strategy based on each participant’s unique arguments and evidence.

These conversations, lasting an average of 8.4 minutes, allowed the AI to directly address and refute the specific evidence supporting each individual’s conspiratorial beliefs, an approach that was impossible to test at scale prior to the technology’s development.

A significant — and durable — effect

The results of the intervention were striking. On average, the AI conversations reduced the average participant's belief in their chosen conspiracy theory by about 20%, and about 1 in 4 participants — all of whom believed the conspiracy beforehand — disavowed the conspiracy after the conversation. This impact proved durable, with the effect remaining undiminished even two months post-conversation.

The AI conversation’s effectiveness was not limited to specific types of conspiracy theories. It successfully challenged beliefs across a wide spectrum, including conspiracies that potentially hold strong political and social salience, like those involving COVID-19 and fraud during the 2020 U.S. presidential election.

While the intervention was less successful among participants who reported that the conspiracy was central to their worldview, it did still have an impact, with little variance across demographic groups.

Notably, the impact of the AI dialogues extended beyond mere changes in belief. Participants also demonstrated shifts in their behavioral intentions related to conspiracy theories. They reported being more likely to unfollow people espousing conspiracy theories online, and more willing to engage in conversations challenging those conspiratorial beliefs.

The opportunities and dangers of AI

Costello, Pennycook, and Rand are careful to point to the need for continued responsible AI deployment since the technology could potentially be used to convince users to believe in conspiracies as well as to abandon them.

Nevertheless, the potential for positive applications of AI to reduce belief in conspiracies is significant. For example, AI tools could be integrated into search engines to offer accurate information to users searching for conspiracy-related terms.

“This research indicates that evidence matters much more than we thought it did — so long as it is actually related to people’s beliefs,” Pennycook said. “This has implications far beyond just conspiracy theories: Any number of beliefs based on poor evidence could, in theory, be undermined using this approach.”

Beyond the specific findings of the study, its methodology also highlights the ways in which large language models could revolutionize social science research, said Costello, who noted that the researchers used GPT-4 Turbo to not only conduct conversations but also to screen respondents and analyze data.

“Psychology research used to depend on graduate students interviewing or conducting interventions on other students, which was inherently limiting,” Costello said. “Then, we moved to online survey and interview platforms that gave us scale but took away the nuance. Using artificial intelligence allows us to have both.”

These findings fundamentally challenge the notion that conspiracy believers are beyond the reach of reason. Instead, they suggest that many are open to changing their views when presented with compelling and personalized counter-evidence.

“Before we had access to AI, conspiracy research was largely observation and correlational, which led to theories about conspiracies filling psychological needs,” said Costello. “Our explanation is more mundane — much of the time, people just didn’t have the right information.”

Chapter 4: Theory in Psychology

4.2 the variety of theories in psychology, learning objectives.

  • Describe three dimensions along which theories in psychology vary.
  • Give examples of several different types of theories in psychology.

Researchers in psychology have found that many different types of theories can help them to organize phenomena, predict what will happen in new situations, and generate new research. It is important for beginning researchers to be aware of the different types so that they recognize theories when they see them in the research literature. (They are not always clearly labeled as “theories.”) It is also important for them to see that some types of theories are well within their ability to understand, use, and even construct. In this section, we look at the variety of psychological theories in terms of three important dimensions: formality, scope, and theoretical approach.

Psychological theories vary widely in their formality —the extent to which the components of the theory and the relationships among them are specified clearly and in detail. At the informal end of this dimension are theories that consist of simple verbal descriptions of a few important components and relationships. The habituation theory of expressive-writing effects on health is relatively informal in this sense. So is the drive theory of social facilitation and inhibition. At the more precise, formal end of this dimension are theories that are expressed in terms of mathematical equations or computer programs.

Formal Theories in Psychology

People who are not familiar with scientific psychology are sometimes surprised to learn that psychological theories can take the form of mathematical equations and computer programs. The following formal theories are among the best known and most successful in the field.

  • ACT-R. A comprehensive theory of human cognition that is akin to a programming language, within which more specific models can be created. See http://act-r.psy.cmu.edu .
  • Prospect theory. A formal theory of decision making under uncertainty. Psychologist Daniel Kahneman won the Nobel Prize in economics based in part on prospect theory. Read about Kahneman’s Nobel Prize work at http://www.nobelprize.org/nobel_prizes/economics/laureates/2002/kahneman-autobio.html .
  • Rescorla-Wagner model. A theory of classical conditioning that features an equation describing how the strength of the association between unconditioned and conditioned stimuli changes when the two are paired. For more on this formal theory—including an interactive version—see http://psych.hanover.edu/javatest/rescrolawagner .

Both informal and formal theories have their place in psychological research. Informal theories tend to be easier to create and to understand but less precise in their predictions, which can make them more difficult to test. They are especially appropriate, however, in the early stages of research when the phenomena of interest have not yet been described in detail. Formal theories tend to be more difficult to create and to understand—sometimes requiring a certain amount of mathematical or computer programming background—but they also tend to be more precise in their predictions and therefore easier to test. They are especially appropriate in the later stages of research when the phenomena of interest have been described in detail

Theories in psychology also vary widely in their scope —the number and diversity of the phenomena they explain or interpret. Many early psychological theories were extremely broad in that they attempted to interpret essentially all human behavior. Freud and his followers, for example, applied his theory not only to understanding psychological disorders but also to slips of the tongue and other everyday errors, dreaming, sexuality, art, politics, and even civilization itself (Fine, 1979). Such theories have fallen out of favor in scientific psychology, however, because they tend to be imprecise and difficult to test. In addition, they have not been particularly successful at organizing or predicting the range and complexity of human behavior at the level of detail that scientific researchers usually seek.

Still, contemporary theories in psychology can vary in their scope. At the broad end of this dimension are theories that apply to many diverse phenomena. Cognitive dissonance theory, for example, assumes that when people hold inconsistent beliefs, this creates mental discomfort that they are motivated to reduce by changing one or both of the beliefs. This theory has been applied to a wide variety of phenomena, including the persistence of irrational beliefs and behaviors (e.g., smoking), the effectiveness of certain persuasion and sales techniques (e.g., asking for a small favor before asking for a big one), and even placebo effects. At the narrow end of this dimension are theories that apply to a small number of closely related phenomena. Consider, for example, a very specific quantitative ability called subitizing. This refers to people’s ability to quickly and accurately perceive the number of objects in a scene without counting them—as long as the number is four or fewer. Several theories have been proposed to explain subitizing. Among them is the idea that small numbers of objects are associated with easily recognizable patterns. For example, people know immediately that there are three objects in a scene because the three objects tend to form a “triangle” and it is this pattern that is quickly perceived (Logan & Sbrodoff, 2003).

As with informal and formal theories, both broad and narrow theories have their place in psychological research. Broad theories organize more phenomena but tend to be less formal and less precise in their predictions. Narrow theories organize fewer phenomena but tend to be more formal and more precise in their predictions.

Theoretical Approach

In addition to varying in formality and scope, theories in psychology vary widely in the kinds of theoretical ideas they are constructed from. We will refer to this as the theoretical approach .

Functional theories explain psychological phenomena in terms of their function or purpose. For example, one prominent theory of repeated self-injury (e.g., cutting) is that people do it because it produces a short-term reduction in the intensity of negative emotions that they are feeling (Tantam & Huband, 2009). Note that this theory does not focus on how this happens, but on the function of self-injury for the people who engage in it. Theories from the perspective of evolutionary psychology also tend to be functional—assuming that human behavior has evolved to solve specific adaptive problems faced by our distant ancestors. Consider the phenomenon of sex differences in human mating strategies (Buss & Schmitt, 1993). Men are somewhat more likely than women to seek short-term partners and to value physical attractiveness over material resources in a mate. Women are somewhat more likely than men to seek long-term partners and to value material resources over physical attractiveness in a mate. But why? The standard evolutionary theory holds that because the male investment in becoming a parent is relatively small, men reproduce more successfully by seeking several short-term partners who are young and healthy (which is signaled by physical attractiveness). But because the female investment in becoming a parent is quite large, women reproduce more successfully by seeking a long-term partner who has resources to contribute to raising the child.

Mechanistic theories , on the other hand, focus on specific variables, structures, and processes, and how they interact to produce the phenomena. The drive theory of social facilitation and inhibition and the multistore model of human memory are mechanistic theories in this sense. Figure 4.4 “Simplified Representation of One Contemporary Theory of Hypochondriasis” represents another example—a contemporary cognitive theory of hypochondriasis—an extreme form of health anxiety in which people misinterpret ordinary bodily symptoms (e.g., headaches) as signs of a serious illness (e.g., a brain tumor; Williams, 2004). This theory specifies several key variables and the relationships among them. Specifically, people who are high in the personality trait of neuroticism (also called negative emotionality) start to pay excessive attention to negative health information—especially if they have had a significant illness experience as a child (e.g., a seriously ill parent). This attention to negative health information then leads to health anxiety and hypochondriasis, especially among people who are low in effortful control, which is the ability to shift attention away from negative thoughts and feelings.

Figure 4.4 Simplified Representation of One Contemporary Theory of Hypochondriasis

Simplified Representation of One Contemporary Theory of Hypochondriasis

This theory focuses on key variables and the relationships among them.

Mechanistic theories can also be expressed in terms of biological structures and processes. With advances in genetics and neuroscience, such theories are becoming increasingly common in psychology. For example, researchers are currently constructing and testing theories that specify the brain structures associated with the storage and rehearsal of information in the short-term store, the transfer of information to the long-term store, and so on. Theories of psychological disorders are also increasingly likely to focus on biological mechanisms. Schizophrenia, for example, has been explained in terms of several biological theories, including theories that focus on genetics, neurotransmitters, brain structures, and even prenatal exposure to infections.

Finally, there are also theoretical approaches that provide organization without necessarily providing a functional or mechanistic explanation. These include stage theories , which specify a series of stages that people pass through as they develop or adapt to their environment. Famous stage theories include Abraham Maslow’s hierarchy of needs and Jean Piaget’s theory of cognitive development. Typologies provide organization by categorizing people or behavior into distinct types. These include theories that identify several basic emotions (e.g., happiness, sadness, fear, surprise, anger, and disgust), several distinct types of intelligence (e.g., spatial, linguistic, mathematical, kinesthetic, musical, interpersonal, and intrapersonal), and distinct types of personalities (e.g., Type A vs. Type B).

Researchers in psychology have found that there is a place for all these theoretical approaches. In fact, multiple approaches are probably necessary to provide a complete understanding of any set of phenomena. A complete understanding of emotions, for example, is likely to require identifying the basic emotions that people experience, explaining why we have those emotions, and describing how those emotions work in terms of underlying psychological and biological variables, structures, and processes.

Key Takeaway

  • Theories in psychology vary widely in terms of their formality, scope, and theoretical approach. The different types of theories all play important roles in psychological research.
  • Practice: Find an empirical research report in a professional journal, identify a theory that the researchers present, and then describe the theory in terms of its formality (informal vs. formal), scope (broad vs. narrow), and theoretical approach (functional, mechanistic, etc.).
  • Discussion: Do you think there will ever be a single theory that explains all psychological disorders? Why or why not?

Amyloid Plaques May Not Cause Alzheimer’s: New Research Challenges Decades-Old Theories

Alzheimers Dementia Brain Disease Concept

A study shows that rising levels of brain protein Aβ42, not the reduction of amyloid plaques, better explains the cognitive benefits of new Alzheimer’s drugs. This finding challenges the traditional focus on plaques in Alzheimer’s treatment.

A new study reveals that the rise in protein levels due to new Alzheimer’s drugs may explain the slowing of cognitive decline just as effectively as the reduction of amyloid plaques.

In a study that questions the effectiveness of newly approved monoclonal antibodies in reducing cognitive decline in Alzheimer’s patients by clearing amyloid, researchers from the University of Cincinnati discovered that an unintended rise in a critical brain protein’s levels correlates just as strongly with cognitive benefits.

Led by UC’s Alberto Espay, MD, the research was published in the journal Brain .

Study background

For decades, the prevailing theory in the field has stated that a protein made up of 42 amino acids called amyloid-beta 42 (Aβ42) hardens into clumps called amyloid plaques, and those plaques damage the brain, causing Alzheimer’s disease.

Espay and team have hypothesized that normal, soluble Aβ42 in the brain is crucial for neuron health and that the loss of Aβ42, rather than the buildup of plaques, drives Alzheimer’s. This includes published research that suggests dementia occurs not when plaque levels are high but when Aβ42 levels drop very low .

According to Espay’s research, the transformation of Aβ42 into plaques appears to be the brain’s normal response to biological, metabolic, or infectious stress.

Alberto Espay

“Most of us will accrue amyloid plaques in our brains as we age, and yet very few of us with plaques go on to develop dementia,” said Espay, professor of neurology in the UC College of Medicine and director and endowed chair of the James J. and Joan A. Gardner Family Center for Parkinson’s Disease and Movement Disorders at the UC Gardner Neuroscience Institute. “Yet the plaques remain the center of our attention in biomarker development and therapeutic strategies.”

Study details

Recently, several new monoclonal antibody medications designed to remove amyloid from the brain were approved after showing they lessened cognitive decline in clinical trials.

Espay and his colleagues noticed that these drugs unintentionally increased levels of Aβ42.

“Amyloid plaques don’t cause Alzheimer’s, but if the brain makes too much of it while defending against infections, toxins, or biological changes, it can’t produce enough Aβ42, causing its levels to drop below a critical threshold,” Espay explained. “That’s when dementia symptoms emerge.”

The team analyzed data from nearly 26,000 patients enrolled in 24 randomized clinical trials of these new antibody treatments, assessing cognitive impairment and differences in levels of Aβ42 before and after treatment. They found that higher levels of Aβ42 after treatment were independently associated with slower cognitive impairment and clinical decline.

“All stories have two sides — even the one we have told ourselves about how anti-amyloid treatments work: by lowering amyloid,” Espay said. “In fact, they also raise the levels of Aβ42. Even if this is unintended, it is why there may be a benefit. Our study shows that we can predict changes in cognitive outcomes in anti-amyloid trials at least as well by the increases in Aβ42 as by the decreases in amyloid.”

Espay said these findings fit well into his larger hypothesis about the root cause of Alzheimer’s, as increasing levels of Aβ42 appear to improve cognition.

“If the problem with Alzheimer’s is the loss of the normal protein, then increasing it should be beneficial, and this study showed that it is,” he said. “The story makes sense: Increasing Aβ42 levels to within the normal range is desirable.”

However, Espay believes these results also present a conundrum for clinicians because removing amyloid from the brain is toxic and may cause the brain to shrink faster after antibody treatment.

“Do we give patients an anti-protein treatment to increase their protein levels? I think the end, increasing Aβ42, doesn’t justify the means, decreasing amyloid,” Espay said. Therapies that directly increase Aβ42 levels without targeting amyloid are a focus of research for Espay and his group.

This means that all the research into plaques is barking up the wrong tree. This is what happens when science focuses on one theory and ignores others. As a medical anthropologist researcher I have studies brain circulation relative to sleep position, and this is essential for brain function. It is a biomechanical issue, not a biochemical issue, which is why most of medicine ignores the impact of sleep position on brain circulation, but Space Medicine researchers study this since astronauts in zero gravity experience a shift of fluid to the head, causing increased brain pressure, reduced brain circulation, and many brain problems, including migraines, eye pressure (glaucoma), and more. They simulate zero gravity on Earth by having people lie flat.

When you elevate the head of the bed 10-30 degrees, it reduced brain pressure and increases circulation. NASA scientists say 30 degree elevation is optimal for heart and brain circulation. We have discovered in our own research that this eliminated migraines, and is already used medically for treating glaucoma, sleep apnea, stroke, and we believe the long-term outcome is dementia/Alzheimer’s.

13:09:2034. About Israeli and Palestinian. Israel and Palestinian war and Conflicts did not started today. This war’s and Conflicts are few Thousands years old. This has been going on since Israeli left Egypt through the Red sea. Today I will like to apologise from Palestinian that am sorry for my involvement in this sagas. I thought as of that time I was making Wright decision. If I have any Forcite which most of times I have. I could have seen what might happen I could have let Israeli to stay in Egypt. Instead of assisted Moses and Israeli escape through the Red sea. I may have forgot some how that there’s people after the red sea living there. Or maybe I thought they may be able to live together in Peace but I was wrong. Since then till today always problems. No day passes by that I did not regret my decision. Let them go through the Red sea was not my only choices before that my plans was to settle them down in some part of West Africa between now called Nigeria and Sudan. Because I may have have some land in that part of the World that time. But before I came back to Egypt I see or know that they were on the move, then my only play was to assist them to cross the Red sea. Before I left to West. I may have told Moses that I will help them. After they cross the Red sea, I don’t know that Fero / Egyptian Army’s will follow them to the sea and into the Red sea. Any ways from then till today I regret my decision. Am sorry that I underestimate Human beings. My thinking then was Israeli don’t have any other usefulness for me in Egypt so I have to relocate them. When I met Israeli I did not remember where they were coming from and where they were going. Because the Israeli must be coming from somewhere and going to somewhere. If I or the Israeli know where they were going or where they were coming from I may have returned them back to there land. Now Israeli don’t have any other places to go back to and I don’t have access to those lands anymore. Now what? Thousands of years mistake or decision is now coming back to hunt me. No new land I can Allocate for my Jewish. Am stuck. No way out. In all this years I always thought one day both Israeli and Palestinian will be able to live together. I was wrong again. Thanks.

The Variety of Theories in Psychology

Learning objectives.

  • Describe three dimensions along which theories in psychology vary.
  • Give examples of several different types of theories in psychology.

Researchers in psychology have found that many different types of theories can help them to organize phenomena, predict what will happen in new situations, and generate new research. It is important for beginning researchers to be aware of the different types so that they recognize theories when they see them in the research literature. (They are not always clearly labeled as “theories.”) It is also important for them to see that some types of theories are well within their ability to understand, use, and even construct. In this section, we look at the variety of psychological theories in terms of three important dimensions: formality, scope, and theoretical approach.

Psychological theories vary widely in their  formality —the extent to which the components of the theory and the relationships among them are specified clearly and in detail. At the informal end of this dimension are theories that consist of simple verbal descriptions of a few important components and relationships. The habituation theory of expressive-writing effects on health is relatively informal in this sense. So is the drive theory of social facilitation and inhibition. At the more precise, formal end of this dimension are theories that are expressed in terms of mathematical equations or computer programs.

Formal Theories in Psychology

People who are not familiar with scientific psychology are sometimes surprised to learn that psychological theories can take the form of mathematical equations and computer programs. The following formal theories are among the best known and most successful in the field.

  • ACT-R .  A comprehensive theory of human cognition that is akin to a programming language, within which more specific models can be created. See  Carnegie Mellow University’s ACT-R site .
  • Prospect theory .  A formal theory of decision making under uncertainty. Psychologist Daniel Kahneman won the Nobel Prize in economics based in part on prospect theory, which he developed with Amos Tversky. Read about Kahneman’s Nobel Prize work .
  • Rescorla-Wagner model .  A theory of classical conditioning that features an equation describing how the strength of the association between unconditioned and conditioned stimuli changes when the two are paired. For more on this formal theory—including an interactive version—see  The Rescorla-Wagner Model of Classical Conditioning . Requires Java.

Both informal and formal theories have their place in psychological research. Informal theories tend to be easier to create and to understand but less precise in their predictions, which can make them more difficult to test. They are especially appropriate, however, in the early stages of research when the phenomena of interest have not yet been described in detail. Formal theories tend to be more difficult to create and to understand—sometimes requiring a certain amount of mathematical or computer programming background—but they also tend to be more precise in their predictions and therefore easier to test. They are especially appropriate in the later stages of research when the phenomena of interest have been described in detail.

Theories in psychology also vary widely in their  scope —the number and diversity of the phenomena they explain or interpret. Many early psychological theories were extremely broad in that they attempted to interpret essentially all human behaviour. Freud and his followers, for example, applied his theory not only to understanding psychological disorders but also to slips of the tongue and other everyday errors, dreaming, sexuality, art, politics, and even civilization itself (Fine, 1979) [1] .

Such theories have fallen out of favour in scientific psychology, however, because they tend to be imprecise and difficult to test. In addition, they have not been particularly successful at organizing or predicting the range and complexity of human behaviour at the level of detail that scientific researchers usually seek. These large theories that attempt to explain everything often end up being vague and can seldom make specific predictions.

Still, contemporary theories in psychology can vary in their scope. At the broad end of this dimension are theories that apply to many diverse phenomena. For example, cognitive dissonance theory proposed by Leon Festinger in 1956 assumes that when people hold inconsistent beliefs, this duality creates mental discomfort that they are motivated to reduce by changing one or both of the beliefs . This theory has been applied to a wide variety of phenomena, including the persistence of irrational beliefs and behaviours (e.g., smoking), the effectiveness of certain persuasion and sales techniques (e.g., asking for a small favour before asking for a big one), and even placebo effects. At the narrow end of this dimension are theories that apply to a small number of closely related phenomena. Consider, for example, a very specific quantitative ability called subitizing. This refers to people’s ability to quickly and accurately perceive the number of objects in a scene without counting them—as long as the number is four or fewer. Several theories have been proposed to explain subitizing. Among them is the idea that small numbers of objects are associated with easily recognizable patterns. For example, people know immediately that there are three objects in a scene because the three objects tend to form a “triangle” and it is this pattern that is quickly perceived (Logan & Sbrodoff, 2003) [2] .

As with informal and formal theories, both broad and narrow theories have their place in psychological research. Broad theories organize more phenomena but tend to be less formal and less precise in their predictions. Narrow theories organize fewer phenomena but tend to be more formal and more precise in their predictions.

Theoretical Approach

In addition to varying in formality and scope, theories in psychology vary widely in the kinds of theoretical ideas they are constructed from. We will refer to this fundamental aspect as their  theoretical approach .

Functional theories  explain psychological phenomena in terms of their function or purpose. For example, one prominent theory of repeated self-injury (e.g., cutting) is that people do it because it produces a short-term reduction in the intensity of negative emotions that they are feeling (Tantam & Huband, 2009) [3] . Note that this theory does not focus on how this reduction happens, but on the function of self-injury for the people who engage in it. Theories from the perspective of evolutionary psychology also tend to be functional—assuming that human behaviour has evolved to solve specific adaptive problems faced by our distant ancestors. Consider the phenomenon of sex differences in human mating strategies (Buss & Schmitt, 1993) [4] .

Men are somewhat more likely than women to seek short-term partners and to value physical attractiveness over material resources in a mate. Women are somewhat more likely than men to seek long-term partners and to value material resources over physical attractiveness in a mate. But why? The standard evolutionary theory holds that because the male investment in becoming a parent is relatively small, men reproduce more successfully by seeking several short-term partners who are young and healthy (which is signaled by physical attractiveness). But because the female investment in becoming a parent is quite large, women reproduce more successfully by seeking a long-term partner who has resources to contribute to raising the child.

Mechanistic theories , on the other hand, focus on specific variables, structures, and processes, and how they interact to produce the phenomena. These types of theories involve identifying a mechanism or explanation for the phenomenon and providing context for when or how intense the phenomenon happens. The drive theory of social facilitation and inhibition and the multistore model of human memory are mechanistic theories in this sense.  Figure 4.3 represents another example—a contemporary cognitive theory of hypochondriasis—an extreme form of health anxiety in which people misinterpret ordinary bodily symptoms (e.g., headaches) as signs of a serious illness (e.g., a brain tumor; Williams, 2004) [5] . This theory specifies several key variables and the relationships among them. Specifically, people who are high in the personality trait of neuroticism (also called negative emotionality) start to pay excessive attention to negative health information—especially if they have had a significant illness experience as a child (e.g., a seriously ill parent). This attention to negative health information then leads to health anxiety and hypochondriasis, especially among people who are low in effortful control, which is the ability to shift attention away from negative thoughts and feelings.

Figure 4.3 Simplified Representation of One Contemporary Theory of Hypochondriasis This theory focuses on key variables and the relationships among them.

Mechanistic theories can also be expressed in terms of biological structures and processes. With advances in genetics and neuroscience, such theories are becoming increasingly common in psychology and research is often criticized when it is does not contain a mechanism. For example, researchers are currently constructing and testing theories that specify the brain structures associated with the storage and rehearsal of information in the short-term store, the transfer of information to the long-term store, and so on. Theories of psychological disorders are also increasingly likely to focus on biological mechanisms. Schizophrenia, for example, has been explained in terms of several biological theories, including theories that focus on genetics, neurotransmitters, brain structures, and even prenatal exposure to infections. If functional theories provide the “why”, then mechanistic theories provide the “how”.

Finally, there are also theoretical approaches that provide organization without necessarily providing a functional or mechanistic explanation. These include stage theories , which specify a series of stages that people pass through as they develop or adapt to their environment. Famous stage theories include Abraham Maslow’s hierarchy of needs and Jean Piaget’s theory of cognitive development. A distinguishing factor of stage theories is that as people pass through the stages, they integrate their outcomes from previous stages to help them succeed in the next stage. In stage theories, progressing forward or stopping is the only option, because stage theories do not allow for reverting to previous stages.   Typologies  provide organization by categorizing people or behaviour into distinct types. These include theories that identify several basic emotions (e.g., happiness, sadness, fear, surprise, anger, and disgust), several distinct types of intelligence (e.g., spatial, linguistic, mathematical, kinesthetic, musical, interpersonal, and intrapersonal), and distinct types of personalities (e.g., Type A vs. Type B). Unlike stage theories, people do not progress through the typologies in any order or at all.

Researchers in psychology have found that there is a place for all these theoretical approaches. In fact, multiple approaches are probably necessary to provide a complete understanding of any set of phenomena. A complete understanding of emotions, for example, is likely to require identifying the basic emotions that people experience, explaining why we have those emotions, and describing how those emotions work in terms of underlying psychological and biological variables, structures, and processes.

Key Takeaway

  • Theories in psychology vary widely in terms of their formality, scope, and theoretical approach. The different types of theories all play important roles in psychological research.
  • Practice: Find an empirical research report in a professional journal, identify a theory that the researchers present, and then describe the theory in terms of its formality (informal vs. formal), scope (broad vs. narrow), and theoretical approach (functional, mechanistic, etc.).
  • Discussion: Do you think there will ever be a single theory that explains all psychological disorders? Why or why not?
