Theoretical framework vs conceptual framework: the difference, with examples

This guide is for students writing a thesis, dissertation or proposal who have been asked to "add a framework". It is part of our planning series; the hub is how to write a research question.

What is a theoretical framework?

A theoretical framework is a set of concepts and premises, developed from one or more existing theories, that a researcher uses to scaffold a study. Varpio and colleagues define it this way in Academic Medicine [1], and describe it as the work a researcher does to use a theory in a specific study.

A theory comes first. A theory is a set of logically related propositions that describe the relationships among concepts and help explain the world [1]. Examples you may meet: the theory of planned behavior in health and psychology [2], the technology acceptance model in information systems and business [3], and self-efficacy theory in education [4].

Grant and Osanloo compare the theoretical framework to the blueprint for a house: it guides the problem statement, the purpose, the questions, the design and the analysis [5].

What is a conceptual framework?

In most theses, a conceptual framework is the researcher's own map of the key concepts or variables in a study and the presumed relationships between them, shown in words, a diagram, or both. This matches Miles and Huberman's widely used description of a conceptual framework as the main things to be studied and the relationships among them [6].

Be aware that the term has a second, broader meaning. Varpio and colleagues define the conceptual framework as the justification for why a study should be done: what is known, the gap, and the methods that follow [1]. Both meanings are used. Check which one your department means before you write.

Theoretical framework vs conceptual framework: side by side

The short version: the theory gives the logic, the conceptual framework applies it to your study.

When does a study need which framework?

Use these decision rules:

• Quantitative, hypothesis-testing study: usually both. Name the theory, then draw the variables and the hypothesized paths. Varpio and colleagues note that in deductive research the theory is usually the starting point and the framework is written before data collection [1].
• Study with no single guiding theory: a conceptual framework built from earlier empirical studies. Explain why no existing theory fits.
• Qualitative study using a theory as a lens: a theoretical framework, used to shape questions or interpret data. A conceptual framework is optional and may be revised as you analyze.
• Grounded theory or fully inductive study: often neither at the start, because building theory is the output. Say this explicitly so examiners do not read it as a gap.

How to build a framework and draw the diagram

Follow these steps once you have a research question.

1. List the concepts in your question and sub-questions: the outcome, the main factors, and anything that might change the relationship.
2. Find theories that explain the relationships. Search for review papers on your outcome and note which theories they use. Pick the one that fits your question best, or combine two and say why.
3. Map theory constructs to your concepts. Make a table: construct, your definition, how you will measure or observe it.
4. Draw the diagram. Put the outcome on the right, causes or predictors on the left, and mediators in between. Draw a moderator as an arrow pointing at another arrow. Number each arrow; each number should match a hypothesis or sub-question.
5. Write the narrative. For each box, a definition and a citation. For each arrow, the reasoning and the evidence.
6. Test the fit. Every box should be measured or explored in your methodology. Every hypothesis should map to an arrow. Remove anything you will not study.

Keep the diagram simple: five to eight boxes is enough for most master's studies. A text diagram is fine for a first draft: Attitude → Intention → Behavior.

Three examples of theoretical and conceptual frameworks

These examples were written for this guide. The theories are real and cited; the studies are illustrations.

Example 1, health: vaccination intention among nurses

• Theoretical framework: the theory of planned behavior, which holds that attitude, subjective norms and perceived behavioral control shape intention, and intention shapes behavior [2].
• Conceptual framework: Attitude toward the seasonal flu vaccine (H1), perceived norms among ward colleagues (H2) and perceived ease of getting vaccinated at work (H3) each predict intention to be vaccinated; intention predicts vaccination status recorded by occupational health (H4). Shift pattern is added as a control.
• Diagram: three boxes on the left, arrows H1 to H3 into "Intention", arrow H4 into "Vaccinated (yes or no)".

Example 2, business: small firms adopting e-invoicing

• Theoretical framework: the technology acceptance model, in which perceived usefulness and perceived ease of use shape the intention to use a technology [3].
• Conceptual framework: In owner-managed firms with fewer than 50 staff, perceived usefulness and ease of use predict intention to adopt e-invoicing; the owner's age moderates the ease-of-use path; a government mandate is shown as an external factor acting on usefulness.
• Diagram: two predictors, one outcome, a moderator arrow pointing at the ease-of-use path.

Example 3, education: math self-efficacy and achievement

• Theoretical framework: Bandura's self-efficacy theory, which proposes that people's beliefs about their capability affect their effort and persistence [4].
• Conceptual framework (qualitative): In a study of grade 9 students who moved from failing to passing math, the framework lists four sources of self-efficacy from the theory as sensitizing concepts for the interview guide: mastery experiences, watching peers succeed, encouragement, and how students read their own anxiety. The analysis stays open to themes outside these four.
• Diagram: four sources around a central box labeled "Math self-efficacy", with a dashed arrow to "Persistence and achievement" because the study explores rather than tests it.

Where does the framework go in a thesis?

The framework usually sits at the end of the literature review chapter, or in a separate section or chapter between the literature review and the methodology. It should then reappear in two places: the methodology, where it justifies what you measure, and the discussion, where you interpret findings against it. If your thesis outline does not yet have a home for it, our thesis outline guide shows typical chapter structures.

Common mistakes

• Listing theories without choosing. Describing five theories and using none. Pick one or two and justify the choice.
• A diagram nobody tests. Boxes that never appear in your measures or analysis.
• Confusing a model with a theory. A diagram from one earlier study is not a theory unless it has been developed and tested as one.
• Ignoring the departmental meaning. Some programs use "conceptual framework" in the broader sense. Ask.

Build a framework in AI for Research

The Theoretical framework module in the Thesis Suite takes your topic or question and returns two to four candidate theories, each with its core idea and how it has been used (cited); the theory or combination it recommends and why; a constructs table (construct, definition, how to measure or observe it); the propositions with a simple text diagram such as A → B → C; and the limits of the framework. It costs 3 credits.

• Check the theory is used in your field with Find Papers (0 credits): search the theory's name with your outcome and filter for reviews.
• Read the original theory paper in My Library and ask questions of the PDF with page citations. See chat with PDF.
• Turn the arrows into hypotheses with the Hypotheses module (3 credits).
• Draw the final diagram yourself in your editor or a drawing tool. The module gives a text diagram, not a finished figure.

The free plan has 45 credits a month; see pricing. The module suggests; you and your supervisor decide which theory fits.

FAQ

What is the main difference between a theoretical and a conceptual framework?

A theoretical framework is built from one or more existing, named theories and explains why the things you study should be related. A conceptual framework is your own map of the specific concepts or variables in your study and how you expect them to connect, often shown as a diagram. The theory supplies the reasoning; the conceptual framework applies it to your question, setting and measures.

Do I need both a theoretical and a conceptual framework?

Not always. Many quantitative theses have both: a theory, then a diagram of the variables drawn from it. A study with no single guiding theory may have only a conceptual framework built from earlier research. Some qualitative designs, such as grounded theory, start with neither and build theory from the data. Your department's handbook and your supervisor decide what is expected, so ask early.

Where does the framework go in a thesis?

In most theses the framework appears at the end of the literature review chapter, or in its own section or chapter between the literature review and the methodology. Some programs put a short version in the introduction. Wherever it sits, the framework should be referred to again in the methodology (to justify measures) and in the discussion (to interpret findings).

Can a conceptual framework be a diagram only?

No. A diagram helps, but it needs text that defines each concept, explains each arrow and cites the theory or studies behind it. Examiners read the text to judge whether the relationships are justified. A diagram without explanation leaves them guessing what the arrows mean and whether you will measure each box.

Is the conceptual framework the same as the literature review?

No, but it grows out of it. The literature review surveys and critiques what is known. The conceptual framework selects the concepts and relationships from that review that your study will examine and arranges them into a model. Some authors use the term more broadly, for the whole argument for why the study is needed, which includes the review and the gap.
