A marketing dissertation at a UK business school normally rests on one of nine theories: the theory of planned behaviour, the technology acceptance model or UTAUT, the stimulus–organism–response model, customer-based brand equity, commitment–trust theory, SERVQUAL, the elaboration likelihood model, service-dominant logic or Hofstede’s cultural dimensions. Pick the one whose variables you can actually measure with the sample you can reach, and the framework chapter writes itself.

This guide is for UK undergraduate and MSc students in marketing, digital marketing, consumer behaviour and international business who have a topic and a supervisor but no theory. It sets out what each framework explains, the data it needs, the criticism a marker expects you to know, and which to choose. It is the marketing companion to our comparison of theoretical frameworks for an education dissertation, and the logic of choosing is the same: a theory is a lens, not a decoration.

What does a theoretical framework do in a marketing dissertation?

It supplies the variables. “What influences students to buy second-hand clothes online” has no variables until a theory names them; the theory of planned behaviour turns it into attitude, subjective norm, perceived behavioural control and intention, each measurable with published items. The framework also supplies the hypotheses, because the theory says which variable predicts which, and the discussion, because your findings either fit the theory or push against it. Markers read the framework chapter to check that the constructs in your questionnaire were derived from somewhere rather than invented; a questionnaire with no theory behind it is the commonest reason a marketing dissertation drops a band on methodology.

Which theory explains why consumers intend to buy?

The theory of planned behaviour, published by Icek Ajzen in 1991 in Organizational Behavior and Human Decision Processes, is the most used framework in UK marketing dissertations: it is fully specified, its constructs come with validated item wording, and it fits any question of the form “why do people intend to do X”. Attitude toward the behaviour, subjective norm and perceived behavioural control predict intention; intention and control predict behaviour.

Data it needs: a cross-sectional survey, typically 150 to 250 respondents, three to five Likert items per construct. The criticism markers expect you to know is that the model explains intention far better than behaviour, and that it has been formally declared exhausted for health behaviour: Sniehotta, Presseau and Araújo-Soares’ 2014 paper in Health Psychology Review is titled “Time to retire the theory of planned behaviour”. Cite it, then justify the model for a purchase-intention study, usually by adding a fourth construct such as perceived value and testing whether it improves the prediction.

Which theory fits apps, e-commerce and anything digital?

The technology acceptance model from Fred Davis’s 1989 paper in MIS Quarterly reduces adoption to two beliefs, perceived usefulness and perceived ease of use, which predict attitude and intention to use. Its 2003 successor, the unified theory of acceptance and use of technology by Venkatesh, Morris, Davis and Davis in the same journal, adds social influence, facilitating conditions and four moderators.

Use TAM for adoption of a specific technology: a retailer’s app, a chatbot, augmented-reality try-on. Use UTAUT when the sample can test moderation, usually 250 or more. Both are so heavily used that the marker will want to see what you added: a context-specific construct such as perceived privacy risk, or an untested population. The standing criticism is parsimony at the cost of explanation; TAM says usefulness matters, not why a given app is perceived as useful.

Which theory explains atmospherics, packaging and social media cues?

The stimulus–organism–response model comes from Mehrabian and Russell’s 1974 environmental psychology and was restated for consumer research by Jacob Jacoby in 2002 in the Journal of Consumer Psychology. A stimulus (store music, website layout, an influencer’s post, sustainable packaging) produces an internal state (pleasure, arousal, trust), which produces an approach or avoidance response (dwell time, purchase, sharing).

It is the most flexible framework on this list, which is its strength and its danger. It fits experiments and surveys; an online experiment with two conditions and 60 to 100 participants is a legitimate undergraduate study. The criticism is that S-O-R is a skeleton: it says there is a mediator but not what it is, so name the organism variables from a second, more specific literature. A dissertation that says only “S-O-R” has not chosen a framework yet.

Which theory should a branding dissertation use?

Customer-based brand equity is Kevin Lane Keller’s 1993 model from the Journal of Marketing: brand equity is the differential effect of brand knowledge on consumer response, and brand knowledge is brand awareness plus brand image (the associations held in memory). David Aaker’s 1991 book Managing Brand Equity gives the parallel five-asset model of awareness, associations, perceived quality, loyalty and other proprietary assets. Use Keller for consumer-side questions and Aaker when the study is about a firm’s brand management.

Data it needs: a survey of consumers of one or two named brands measuring awareness, associations, perceived quality and loyalty with scales from the applied literature. The concepts are intuitive, which is why brand equity dissertations score well on framework and poorly on findings: the model is descriptive, so ask something the data can answer, such as whether one association predicts loyalty more than another, rather than simply mapping the brand.

Which theory explains loyalty and relationships?

The commitment–trust theory of relationship marketing, from Morgan and Hunt’s 1994 paper in the Journal of Marketing, holds that commitment and trust mediate between a firm’s behaviour (shared values, communication, opportunistic behaviour) and outcomes such as propensity to leave and cooperation. Use it for loyalty schemes, subscription retention, B2B supplier relationships or the trust problem in influencer marketing.

Data it needs: a survey of existing customers, or a B2B sample reached through a placement, measuring trust and commitment with established scales, typically 120 to 200 respondents. The marker will look for a fresh context rather than a replication. The criticism is that the theory was built on channel relationships between firms and travels imperfectly to consumer contexts where switching is cheap.

Which theory fits a service quality dissertation?

SERVQUAL, from Parasuraman, Zeithaml and Berry’s 1988 paper in the Journal of Retailing, measures the gap between expected and perceived service on five dimensions: tangibles, reliability, responsiveness, assurance and empathy. It comes with a 22-item instrument and fits hospitality, banking, higher education, healthcare and retail.

The criticism must be engaged with: the expectations-minus-perceptions difference score is statistically awkward, and Cronin and Taylor’s 1992 SERVPERF alternative argues that perceptions alone predict satisfaction better. SERVQUAL without SERVPERF signals a shallow literature review. Check the reliability of each dimension in your own sample and report it, using the thresholds in our guide to acceptable Cronbach’s alpha values, because the empathy and tangibles dimensions routinely underperform.

Which theory explains whether advertising persuades?

The elaboration likelihood model by Petty and Cacioppo (1986) proposes two routes to persuasion: a central route, where the audience processes the argument, and a peripheral route, where cues such as source attractiveness, number of likes or celebrity endorsement do the work. Motivation and ability decide which route operates. It is the natural framework for influencer marketing, sponsored-content disclosure, green claims or comparative advertising.

Data it needs: an online experiment manipulating argument quality and a peripheral cue in a 2 × 2 design, 80 to 120 participants, with a manipulation check. Pair it with Ohanian’s 1990 source-credibility scale when the cue is an endorser, and be ready for the question whether social media users ever process centrally at all.

Which theory suits a conceptual or qualitative marketing dissertation?

Service-dominant logic, set out by Vargo and Lusch in 2004 in the Journal of Marketing, reframes all exchange as service, with value co-created by the customer and the firm rather than embedded in a product. It is the framework of choice for MSc dissertations on co-creation, platforms, customer communities and sustainability, and it works with interviews, netnography and case studies where the previous theories demand a survey.

Its weakness is that it explains everything and predicts nothing: no variables to operationalise, no hypotheses to test, so a dissertation using it must be explicitly interpretive and say so in the methodology. The foundational premises have been revised repeatedly since 2004; cite the current set.

Which theory should an international marketing dissertation use?

Hofstede’s cultural dimensions, first published in 1980 and extended since, score national cultures on dimensions including power distance, individualism, masculinity, uncertainty avoidance, long-term orientation and indulgence. Two-country comparisons of advertising appeals or brand perceptions use the scores as the explanatory variable.

Use it only if you can sample in both countries. The criticism is severe and must appear in the chapter: McSweeney’s 2002 critique in Human Relations argues that the dimensions were derived from a single company’s employee survey and cannot represent national cultures. The safe design uses the dimensions as a heuristic and measures cultural values at the individual level with a validated scale rather than assigning respondents their country’s score.

How do you choose between them?

Two rules cut the list. If your data will be a questionnaire, the framework needs constructs with published items, which rules out service-dominant logic. If your sample will be under 100, choose an experiment over a survey model, because the power argument in our guide to sample size for an undergraduate dissertation applies with full force to a five-construct regression. The realistic response rate for a student survey is lower than most proposals assume; the figures in our analysis of business dissertation survey response rates should shape the framework decision, not follow it.

Where does the framework go, and how long should it be?

In most UK business schools the framework closes the literature review, 1,000 to 1,500 words of a 10,000-word dissertation, ending with a labelled figure of the model and a numbered list of hypotheses. The methodology then explains how each construct was measured and the discussion returns to each hypothesis. The methodology conventions for the survey designs above, including the ethics and access questions for a firm-based sample, are in our guide to the methodology chapter of a business dissertation. If the framework is still being chosen at proposal stage, the structure in our guide to writing a dissertation proposal shows where the theory statement sits.

Can you combine two frameworks?

Yes, but only in one direction: a general model extended with one construct from a second literature. TPB plus perceived value, TAM plus privacy risk, S-O-R with trust as the organism variable. Combining two full models produces a questionnaire nobody finishes and a regression with more predictors than your sample can support. Name the base theory, name the extension, and justify in one paragraph why the base alone is insufficient.

When the theory is chosen and the chapter is still blank

Tesify can build the theoretical framework section around the theory you have chosen, working from your research question, your constructs and the papers you have read, so the chapter moves from definition to model to hypotheses in the order a marker expects. The choice of theory, the argument and the reading stay yours and are 100% written by you; what you get is structure and momentum on the chapter students leave until last.

Frequently asked questions

What is the most common theoretical framework in marketing dissertations?

The theory of planned behaviour, followed closely by the technology acceptance model. Both are fully specified survey models with published scale items, which is why they dominate undergraduate work and why markers expect a contextual extension rather than a straight replication.

Do I need a theoretical framework for a qualitative marketing dissertation?

Yes, but it works differently: an interpretive study uses a framework such as service-dominant logic as a sensitising lens rather than a source of hypotheses, and the methodology must say so.

Can I use the 4Ps or SWOT as my theoretical framework?

No. The marketing mix and SWOT are planning tools, not theories; they describe decisions rather than explain behaviour. Markers treat a dissertation framed on them as having no framework at all.

How many theories should I discuss?

Review two or three briefly, then commit to one and justify it. A chapter that describes six theories and chooses none is a literature summary, not a framework.

Is SERVQUAL still acceptable in 2026?

Yes, provided you engage with the SERVPERF critique and report the reliability of each dimension in your own data. Using the 22 items without that discussion is the most common weakness in service quality dissertations.

Can I use Hofstede if my sample is only in the UK?

Only as a heuristic. With one country you cannot vary the national scores, so measure cultural values at the individual level with a validated scale and use Hofstede’s dimensions to interpret rather than to test.

Where do the hypotheses come from?

From the framework. Each path in the model becomes one hypothesis, worded so that a specific statistical test can support or fail to support it. If a hypothesis has no path in your model, either the model is incomplete or the hypothesis does not belong.

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

The theoretical framework is the established theory you adopt; the conceptual framework is your own model of how the constructs relate in your specific study, usually the theory plus your extension, drawn as a figure. UK business schools expect both, with the conceptual model at the end of the literature review.
