Theoretical Framework vs Conceptual Framework

Your advisor asks for a theoretical framework, your template asks for a conceptual framework, and half the sources you read treat the two terms as the same thing. Mix them up and a whole section of your dissertation can end up doing the wrong job.

In our experience coaching 10,000+ students, the difference is simpler than the jargon makes it look. In this post, I’ll show you what each framework does, how one grows out of the other, and whether you need both, using real frameworks from completed dissertations.

The difference at a glance

The simplest way to remember the difference: one framework is borrowed from the literature, and the other you build for your own study, usually on top of the first. Side by side:

	Theoretical framework	Conceptual framework
What it is	An established theory (or a few) your study builds on	Your map of the concepts or variables in your study and how you expect them to relate
Where it comes from	The literature: someone else developed it	You build it, from theory and previous studies
Usual form	A written discussion	Often a diagram of boxes and arrows, plus a written explanation
The question it answers	What lens am I looking through?	What do I expect to find, and how do the pieces connect?
Where it usually goes	Varies by program; often developed in the literature review	Alongside or just after the theory, wherever that sits

That’s the clean version. In practice the terms get used loosely, so whether you need both (covered below) matters as much as the definitions.

What is a theoretical framework?

A theoretical framework is the established theory, or small set of theories, that your study is built on. It gives you a lens: the concepts, assumptions and explanations you’ll use to design the study and to make sense of what you find.

You don’t invent it. You choose it from the literature, then justify the choice: why this theory suits your research questions, and how much of it you’re adopting. You rarely need the whole theory. Most studies take the parts that matter to them and say which parts those are.

In practice, stating a theoretical framework can be short. Here’s a PhD in information science doing it, reason included, in a single sentence:

Notice the word “because”. Chen names the perspective, then says why it fits: it accounts for the thing the study cares about, the role of information in career decisions. That’s the core of a theoretical framework statement, and one sentence is enough to open it. For five more real theoretical frameworks, with our comments on each, see theoretical framework examples.

What is a conceptual framework?

A conceptual framework is your own map of the concepts or variables in your study and how you expect them to relate. It’s often drawn as a diagram, with boxes for the constructs or variables and arrows for the relationships you expect between them.

In a quantitative study, each arrow is usually a hypothesis, and each one should trace back to a theory or to previous studies. That’s why your hypotheses come straight out of the conceptual framework, and why an arrow nobody has argued for is just a guess.

To see what that looks like, here’s the conceptual framework from my own master’s dissertation, which looked at what drives a client’s trust in an online broker:

The left-hand column holds the study’s independent variables, split into the client’s own traits and their perceptions of the broker; the right-hand box is the one outcome the study set out to explain. The study’s whole argument fits on one page, and every arrow is a hypothesis it set out to test.

Written down, a conceptual framework can be just as plain. Here’s how a doctoral study in finance describes its own:

Independent variable, dependent variables, control variables: the role of each is named outright. That’s the written half of a conceptual framework, and your diagram should say the same thing in boxes and arrows.

How they fit together

The two frameworks aren’t rivals. In most quantitative studies, the theory comes first and the conceptual framework is built out of it. The theory tells you which concepts matter, and your framework turns them into variables you can measure and relationships you can test.

This master’s thesis at Cornell shows the hand-off clearly. It opens with its theory, then turns that theory into things it can measure:

Those two attitudes then become boxes in the study’s research model, which is its conceptual framework:

Read the figure left to right and you have the whole relationship in one picture. The theory explains why usefulness and playfulness should matter; the conceptual framework says exactly how they matter in this study, and turns each claim into a hypothesis the data can support or reject. If you can’t draw a line from your theory to your model, one of them needs more work.

Do you need both?

If the two work together that neatly, do you need both? Often, no. Plenty of studies work with one: a qualitative study might need only a theoretical lens, and some quantitative studies present their theory and their model as a single framework. Some programs, though, require both as separate sections, so check your program’s guidelines first.

Part of the confusion is that the terms aren’t used consistently, even by academics. Writing about dissertation research, Grant and Osanloo put it bluntly:

Note who’s confused: students and committee members. A 2020 paper in Academic Medicine adds that the terms “are used in different ways in different research approaches”. So if your advisor (supervisor, in the UK) uses either term differently from this post, ask what they mean, and write to their definition.

Where does each one go?

There’s no single answer, because programs differ. A common pattern is to introduce whichever framework you’re using (theoretical, conceptual or both) briefly in Chapter 1, then develop it in the literature review, where the theory and studies behind it are discussed. Other programs want a separate section or chapter for it. Past dissertations from your department will show you the local convention.

If you have both, the theoretical framework usually comes first, and the conceptual framework follows from it, often ending with the hypotheses it implies.

What doesn’t vary is that neither framework can stay where you introduce it. Grant and Osanloo describe students who “briefly make mention of a theoretical framework at the start of the dissertation and never return to it throughout the rest of the document”. Point back to them in your methodology, where they justify what you measured and how, and in your discussion, where you interpret your findings against them.

What about qualitative studies?

Qualitative studies use frameworks differently. Many start with a theoretical lens that shapes what they look at, but no diagram of variables and hypotheses. There’s a real difference between a framework that informs your analysis and one that dictates it: if every interview question and every code comes straight from the framework, your study has become deductive, whether you meant it to or not.

Some strongly inductive studies start with no framework at all and let theory come out of the data. Grant and Osanloo note that in a less structured qualitative design, “the theoretical framework often emerges in the data analysis phase.” That’s legitimate, as long as you say so and explain why.

Where students go wrong

Most framework problems we see are one of a handful. Here are the ones I usually look out for.

Listing theories instead of using one. A theoretical framework isn’t a tour of every theory you read. Pick one or two, give each a job, and show how it shapes your study.

Drawing arrows nobody has argued for. Every relationship in your conceptual framework needs support from theory or previous studies. If you can’t give a reason for an arrow, justify it or cut it.

Proposing relationships you never test. Every arrow in your conceptual framework is a promise your analysis has to keep. If your study doesn’t examine a relationship, it shouldn’t be on the diagram.

Confusing your framework with your research philosophy. Your paradigm (positivism or interpretivism, say) is your stance on knowledge; your theoretical framework is the theory you study through. They’re different things, and each needs its own treatment.

Adopting a whole theory by default. You can take the parts of a theory that fit your study and leave the rest, as long as you say which parts and why.

Get these right and the rest of your dissertation has something solid to stand on.

Still have questions?

How do I choose a theoretical framework?

Start from your research questions, not from a list of theories. Look at what the key studies in your area use, shortlist the theories that explain the relationships or experiences you’re studying, and choose the one that fits your questions most closely. Your advisor may have preferences, and some programs keep a list of approved theories, so ask early.

Is a conceptual framework the same as a model?

Often, yes. Many studies call their diagram a conceptual model or a research model; Verdiguel’s thesis calls its version an “Overall Research Model”. What matters is the job it does: mapping your variables and the relationships you expect. Some fields use “model” for something more formal, so follow your program’s usage.

Can I create my own conceptual framework?

Yes, that’s the point of one. You build it for your study, but not from nothing: each concept and each relationship should come from theory or previous research. Combining parts of several theories is fine, as long as you explain why each part is there.

Does a conceptual framework need hypotheses?

In a quantitative study, usually yes, because each arrow is a relationship you’ll test. A qualitative conceptual framework is different: it sets out the concepts you expect to matter and how they might connect, without predictions to test.

Can I use a theory from another field?

Yes, and it’s common. Management studies often borrow from psychology, and nursing studies from behavioral science. Explain why the theory transfers to your setting, and cite studies that have used it there if you can.
