A theoretical framework uses an established theory or theories to explain or interpret the research problem. A conceptual framework sets out the study’s key concepts and proposed relationships, drawing on relevant theory, evidence and the researcher’s reasoned choices. Terminology overlaps across disciplines and institutions, so this distinction is a useful working convention rather than a universally enforced rule.
Reading relevant literature helps you identify explanations, define concepts and justify relationships. AnswerThis’s AI literature review generator retrieves scholarly records and available abstracts to draft an outline and one cited opening paragraph, with linked sources and search scope. Use this preview to organize initial reading: examine how relevant papers apply theories and define concepts, then read their full texts before deciding what belongs in your framework. AnswerThis supports that literature-grounded starting point, while you select the explanatory perspective and justify the study-specific connections.
TL;DR
A theoretical framework explains how selected theory informs your investigation, rather than merely summarizing a theorist.
A conceptual framework connects the concepts relevant to your question and explains why they belong together.
Either can use a diagram, support qualitative research or draw on several theoretical sources.
Define concepts, justify relationships and connect the framework to evidence and analysis.
Theoretical vs conceptual framework: key differences
Think of the distinction as explanatory perspective versus study-specific organization. A theoretical framework example might use Self-Determination Theory to interpret students’ motivation. A conceptual framework example might connect perceived autonomy support, internet access and engagement in a particular learning setting.
These functions can coexist. A conceptual framework can incorporate theory without becoming a new theory. Either framework can combine compatible explanations or support qualitative research.
Main purpose

Conceptual framework: Organizes the study’s concepts and proposed relationships.
Starting point
Theoretical framework: An explanatory perspective suited to the question.
Conceptual framework: The question, relevant theory, evidence and reasoned choices.
What it contains
Theoretical framework: Selected constructs, assumptions and their application.
Conceptual framework: Defined concepts, boundaries and justified connections.
How it guides the study
Theoretical framework: Directs questions, interpretation and potentially measurement.
Conceptual framework: Connects what will be investigated with evidence needed.
Presentation
Theoretical framework: An applied written argument, optionally with a diagram.
Conceptual framework: A written explanation, optionally with a relationship map.
Change during research
Theoretical framework: Application or assumptions may be reconsidered transparently.
Conceptual framework: Concepts and links may be refined as understanding develops.
The USC Libraries guidance on theoretical frameworks emphasizes explaining how a researcher uses theory and its assumptions to investigate a problem. That application is the essential work: naming a theory does not yet show what it contributes.
Theoretical framework examples by field
The applications and sample paragraphs below are illustrative proposals, not published studies or findings. Their country settings define potential sites, not national characteristics. Each project would need to examine contextual fit, access and suitable measures before proceeding.
Education: Self-Determination Theory
Edward L. Deci and Richard M. Ryan’s foundational book, Intrinsic Motivation and Self-Determination in Human Behavior (1985), developed Self-Determination Theory. Later formulations elaborate its account of autonomy, competence and relatedness, including Ryan and Deci’s 2000 article in American Psychologist, 55(1), 68–78. The three-need account should not be treated as if every detail appeared fully formed at one date.
Autonomy concerns acting with volition, not simply working alone or receiving choices. Competence concerns feeling effective; relatedness concerns connection and belonging. Rewards and options are features of an environment, not substitutes for these experiences.
Illustrative question: How do postgraduate students at a university in India describe supervision practices in relation to autonomy, competence and relatedness?
Interviews could explore feedback and decision-making, with the constructs guiding interpretation rather than fixing categories.
Sample framework paragraph:
This proposed study uses Self-Determination Theory to examine postgraduate students’ accounts of supervision at a university in India. Autonomy, competence and relatedness will guide interview prompts about decision-making, feedback and supervisory relationships. The analysis will distinguish opportunities offered by supervisors from students’ experiences of those opportunities. These constructs provide an interpretive starting point, not predetermined findings. Accounts that challenge the framework will remain visible, and the study will examine how students understand the constructs in their setting.
Public health: Health Belief Model
The Health Belief Model developed through applied work by US Public Health Service researchers in the 1950s, including Godfrey Hochbaum, Irwin Rosenstock and Stephen Kegeles. Rosenstock’s “Historical Origins of the Health Belief Model” (1974), Health Education Monographs, 2(4), 328–335, is a historical account, not the model’s single origin date.
Perceived susceptibility concerns personal risk, severity concerns consequences, benefits concern expected advantages of action, and barriers concern perceived obstacles. Cues to action are prompts that may trigger action. Self-efficacy concerns perceived capability to perform it; Rosenstock, Victor Strecher and Marshall Becker explicitly incorporated it in “Social learning theory and the Health Belief Model” (1988), Health Education Quarterly, 15(2), 175–183.
Illustrative question: How do adults invited to blood-pressure screening at a clinic in Kenya describe their decisions about attending?
Interviews could distinguish screening beliefs from practical constraints. An established model can inform a theoretical framework without becoming a theory.
Sample framework paragraph:
This proposed study uses the Health Belief Model to organize accounts of blood-pressure screening decisions at a clinic in Kenya. Interviews will explore perceived susceptibility and severity, expected benefits, barriers, cues to action and self-efficacy. The analysis will distinguish beliefs about screening from practical constraints reported by participants. The model offers a vocabulary for examining decisions, but it will not be used to assume that nonattendance reflects low motivation or that individual beliefs explain all service-access problems.
Information systems or business: Technology Acceptance Model
Fred D. Davis’s “Perceived Usefulness, Perceived Ease of Use, and User Acceptance of Information Technology” (1989), MIS Quarterly, 13(3), 319–340, provides a foundational publication on the Technology Acceptance Model’s central beliefs. It is distinct from the related 1989 Management Science paper by Davis, Richard Bagozzi and Paul Warshaw comparing two models.
Perceived usefulness concerns whether using a system is expected to improve work performance. Perceived ease of use concerns expected freedom from effort. A system can seem easy without seeming useful, so these constructs need separate questions and measures.
Illustrative question: How are perceived usefulness and perceived ease of use associated with research-software use among postgraduate students at a university in Malaysia?
A proposed survey could measure both beliefs separately, with consented usage records providing a distinct behavioral measure. Social influence or trust would require an explicit extension, not silent attribution to the original formulation.
Sample framework paragraph:
This proposed study draws on the Technology Acceptance Model to examine research-software use among postgraduate students at a university in Malaysia. Perceived usefulness and perceived ease of use will be defined separately and examined alongside recorded use where access permits. The framework will guide questionnaire selection and interpretation without treating favorable beliefs as equivalent to actual use. Institutional requirements and access conditions will be documented as context rather than silently added to the original model.
Psychology or professional learning: Social Cognitive Theory
Albert Bandura’s Social Foundations of Thought and Action: A Social Cognitive Theory (1986, Prentice-Hall) articulated Social Cognitive Theory, building on earlier work including Social Learning Theory (1977). The 1986 formulation is not simply another title for the earlier book.
Its reciprocal perspective connects personal factors, behavior and environment. Self-efficacy is belief in capability for a particular activity, while outcome expectations concern anticipated consequences. Observing others and regulating one’s actions also matter; the theory is not just a statement that confident people perform better.
Illustrative question: How do newly qualified teachers in a United Kingdom mentoring program describe interactions among feedback, teaching practice and task-specific self-efficacy?
Repeated interviews, observations and reflective accounts could examine how those elements develop together. A single confidence survey would not capture reciprocal processes across time.
Sample framework paragraph:
This proposed study uses Social Cognitive Theory to investigate professional learning within a United Kingdom mentoring program. Task-specific self-efficacy, teaching behavior and the mentoring environment will organize repeated interviews and observations. The analysis will examine whether participants describe changes in one element alongside changes in others, including unexpected patterns. Observation of mentors and opportunities to practice will be considered without reducing learning to confidence alone. Reciprocal influence remains an explanatory proposition, not an effect established by these accounts.
How to write a theoretical framework
Select for explanatory fit, then turn that explanation into an applied argument.
Define the problem and question. State what requires explanation or interpretation. A topic such as online learning does not yet identify whether your concern is participation, motivation or access.
Review relevant explanations. Compare theories used for similar questions and read their foundational accounts. The guide to how to write a literature review explains how to synthesize evidence rather than accumulate summaries.
Select for explanatory fit. Explain what the chosen theory helps you understand and why alternatives are less suitable. Popularity and citation counts are not evidence of fit. If combining theories, explain compatibility and what each contributes.
Define relevant constructs. Select the concepts needed for your question, distinguish overlapping terms and cite the formulation you actually use. Explain any adaptation rather than presenting it as original terminology.
Connect framework and method. Show how constructs inform recruitment, prompts, measures, coding or interpretation. Specify what evidence could challenge your reading as well as support it.
Address contextual fit and limitations. Consider language, institutional arrangements and assumptions about action or experience. Explain what the framework leaves outside its scope.
Applying a framework is not automatically testing the theory itself. Using autonomy to interpret interviews applies a construct; evaluating a specified theoretical proposition requires evidence and an analysis designed for that purpose. State which task your project undertakes.
How to build a conceptual framework
A conceptual framework makes your study-specific reasoning visible. Consider this worked question: How are access to stable internet and perceived autonomy support associated with online learning engagement among postgraduate students in a defined university setting?
1. Define the question and units of analysis
Treat individual postgraduate students as the units and specify the university, learning format and observation period in the protocol. This bounds the proposed project without assuming conditions across an entire country or institution.
2. Identify concepts from theory and relevant evidence
Perceived autonomy support draws on Self-Determination Theory’s account of supportive learning environments. Stable internet access enters as a contextual resource relevant to participation. Literature review must justify its inclusion rather than treating a plausible connection as an established result.
3. Define the concepts in this study
Decide whether engagement means participation, sustained effort, cognitive involvement or a justified combination. Define stable access in relation to the learning activities students need to undertake. Keep perceived autonomy support distinct from autonomy itself: one concerns the environment as experienced, the other concerns volition.
4. Propose relationships and explain their rationale
Stable access may enable participation in online tasks, while autonomy-supportive teaching may relate to students’ engagement. These are propositions to examine, not conclusions. The following compact relationship map provides a readable alternative to a graphical diagram.
Illustrative conceptual-framework relationship map
Stable internet access → Online learning engagement
Meaning of the arrow: Examine the association between access and engagement.
Perceived autonomy support → Online learning engagement
Meaning of the arrow: Examine the association between perceived support and engagement.
Illustrative conceptual framework. Arrows represent proposed relationships, not established causal effects.
Here, arrows identify associations to examine, not established causal direction. Always define their meaning.
Example framework paragraph:
This proposed study examines stable internet access and perceived autonomy support in relation to postgraduate students’ online learning engagement. Autonomy support supplies a theory-informed concept concerning students’ learning environment, while internet access represents a contextual resource. The framework proposes two associations for investigation within the defined university setting. It does not assume either association exists or that the framework captures every influence on engagement. Evidence will inform whether these relationships remain useful and how their interpretation should be bounded.
Stable internet access
Meaning in this study: Reliability of connection for specified online learning activities during the observation period.
Possible evidence: Defined interruption reports or consented connection records where available.
Perceived autonomy support
Meaning in this study: Students’ perceptions that teaching acknowledges their perspective and supports volitional participation.
Possible evidence: Appropriately adapted questionnaire items and accounts of teaching interactions.
Online learning engagement
Meaning in this study: The selected dimensions of participation or involvement in the course.
Possible evidence: Suitable engagement measures, activity records and contextual accounts.
Internet access is not an original Self-Determination Theory construct. Its place in this framework requires a separate rationale. Proposed measures also need suitable definitions, evidence of validity for their intended use and contextual checking; platform logins alone should not stand in for all engagement.
5. Decide what evidence addresses the relationships
Align access, support and engagement measures over compatible periods. A questionnaire could estimate associations, while interviews could explore how students describe the proposed connections. Access permissions, missing records and differences between reported experience and recorded behavior affect interpretation.
6. Revise with a stated reason
Pilot work may reveal unclear concepts or unsuitable measures. Record revisions and distinguish pre-analysis changes from later interpretations. Do not add variables merely to make the framework look sophisticated.
Where do these frameworks go in a thesis?
Common placements include a dedicated framework section or chapter, a section within the literature review, or an account immediately after it. Institutional guidance and disciplinary conventions determine placement. There is no universal chapter number, word count or requirement to include both frameworks separately.
The literature review evaluates and synthesizes relevant research. The framework identifies the concepts and explanatory perspective guiding this study. Methodology then explains and justifies how the question will be investigated. These roles overlap in writing, but each must remain traceable.
Connect the framework to methodology through construct definitions, evidence and analysis, rather than leaving it in an isolated chapter. The guide to research methodology examples provides an entry point for considering different approaches. Select methods because they address the question, not because a framework label appears to require a survey or interviews.
Common framework mistakes
Naming without applying. Replace a theorist’s biography with an explanation of which constructs guide your study and how they enter evidence collection or interpretation.
Choosing through popularity. Compare explanatory fit and assumptions. Explain why the selected perspective addresses your problem better than plausible alternatives.
Drawing unexplained arrows. State what each connection means and provide its rationale. A neat diagram cannot supply missing theoretical or empirical support.
Combining incompatible constructs. Identify their source, definition and role. Explain how different perspectives fit together instead of assembling an unconnected list.
Turning proposals into causal findings. Match claims to design and evidence. Distinguish theoretical explanations from associations estimated in an observational project.
Keeping disconnected concepts. Remove concepts that do not contribute to the question or explain why evidence cannot address them. Every retained element should have a clear analytical role.
FAQs
What is the difference between a theoretical and a conceptual framework?
A theoretical framework applies established theory or models to explain or interpret a problem. A conceptual framework organizes a study’s concepts and proposed relationships using theory, evidence and reasoned choices. This working distinction helps clarify purpose, but institutions and disciplines sometimes use the labels differently or combine their functions.
Do I need both frameworks in my thesis?
Not necessarily. One integrated account may explain the theoretical perspective and the study-specific concepts sufficiently. Check your department’s guidance and discuss expectations with your supervisor. The important requirement is a justified connection between the question, concepts, evidence and interpretation, not two chapters repeating the same argument under different labels.
Can a conceptual framework use an existing theory?
Yes. Established theory can provide concepts and explanations while the conceptual framework specifies their role in this project. Other evidence or contextual resources may also belong. Identify their origins and justify the connections, rather than implying that every element comes from the theory or that the combined framework is itself a new theory.
Does a framework need a diagram?
No. A clear written account can define constructs, assumptions and relationships without a visual. A diagram or compact relationship table helps when readers need to see several connections together. It should accompany an explanation of the links, not replace it, and should remain readable at the size used in the thesis.
Can qualitative research use a theoretical framework?
Yes. Theory can inform qualitative questions, sampling, interview prompts and interpretation. Researchers should explain whether concepts guide initial coding, act as sensitizing ideas or enter later interpretation. They should also retain evidence that challenges the framework, rather than forcing every account into predefined categories or assuming all qualitative approaches use theory identically.
Write your research question, identify the concepts needed to address it, and explain why the selected theory or proposed relationships help guide the investigation. Then check that each concept connects to evidence you can obtain and analyze.
