The Relationship Between Theory and Qualitative Research Is Methodologically Diverse
Qualitative research is not inherently theory-free
The idea that qualitative research simply collects participants' experiences without theoretical influence is difficult to sustain.
Researchers make decisions about what phenomenon to investigate, what questions to ask, whom to interview or observe, what counts as relevant evidence, how concepts are understood, and how findings should be interpreted. Those decisions are influenced by disciplinary knowledge, methodological assumptions, epistemological commitments, previous literature, and sometimes explicit theory.
Collins and Stockton argue that theory can permeate many aspects of qualitative research even when researchers do not fully recognize its influence. They also describe theoretical frameworks as potentially providing focus, connection with existing scholarship, critical perspective, and support for interpretation.
The issue is therefore not whether qualitative researchers can somehow remove every theoretical influence. It is whether those influences are recognized and used in ways that remain coherent with the methodology.
A theoretical framework can guide a qualitative study from the beginning
Some qualitative studies explicitly select a theoretical perspective before data collection.
The framework may help formulate the research question, identify phenomena requiring attention, inform sampling decisions, shape interview or observation prompts, influence coding, and provide concepts for interpreting findings.
Green, for example, describes qualitative case study research in which a conceptual framework was used to determine research questions and provide direction to interviews and discussions. This illustrates that using a framework from the beginning is not inherently incompatible with qualitative inquiry.
In such a design, the researcher should explain what the theory actually does in the study rather than merely naming it in the literature review.
Theory can function as a lens rather than a prediction system
Theory does not have to produce hypotheses to contribute to qualitative research.
A theoretical lens can foreground particular aspects of experience, interaction, institutions, identity, culture, power, learning, or another phenomenon. It provides concepts through which researchers can ask questions and interpret meaning.
For example, a researcher investigating student experiences of generative AI might use a theoretical perspective concerned with agency. The theory could sensitize the researcher to how students describe control, choice, responsibility, and constraint without requiring a prediction such as “greater agency will cause greater AI use.”
This is one reason applying theory in qualitative inquiry should not automatically be equated with quantitative-style theory testing.
Theory can provide sensitizing concepts
A particularly useful distinction in qualitative inquiry is between concepts that sensitize researchers and categories that rigidly determine the analysis.
A sensitizing concept suggests what may be worth noticing. It provides orientation without specifying exactly what empirical instances must look like.
Suppose previous theory suggests that professional identity may matter when teachers decide whether to use generative AI. Researchers might enter interviews attentive to how participants discuss what a “good teacher” should or should not delegate to AI. Yet participants might introduce entirely different considerations, such as assessment fairness, institutional surveillance, or emotional discomfort.
If those unexpected ideas remain visible and analytically important, theory is helping researchers look without completely deciding what they will see.
Theoretical frameworks can also narrow what researchers notice
The focusing power of theory is simultaneously its strength and its risk.
Collins and Stockton explicitly caution that overreliance on theory can limit researchers' ability to see emergent findings. More recent critical discussion of conceptual frameworks in qualitative health research similarly warns that frameworks can become prescriptions for data collection and analysis and may replace deeper engagement with the data.
This problem becomes especially important when every interview question comes directly from theoretical constructs, every code is predetermined, and observations outside the framework are treated as irrelevant.
Watch Out
If your theoretical framework determines in advance what participants are allowed to mean, the framework may be doing too much. Qualitative analysis should not become an exercise in locating quotations for boxes that were already drawn before anyone was interviewed.
The methodology should influence when theory enters
Different qualitative traditions position theory differently.
A critical qualitative study may adopt an explicit theoretical perspective from the beginning because the theory is central to how the researcher understands the phenomenon. A qualitative case study may use a conceptual framework to focus inquiry across cases. Other approaches may place greater emphasis on inductive development and limit predetermined theoretical categories.
Green notes that some qualitative methods do not overtly use a theoretical or conceptual framework in the research design even though theoretical assumptions may remain implicit in the methodological approach.
Consequently, the question whether every study needs a theoretical or conceptual framework cannot be resolved independently of methodology.
Grounded theory requires particular care
Grounded theory is frequently invoked in discussions about whether qualitative research should begin with an established theory.
Its purpose is not simply to collect qualitative data and identify themes. Grounded theory methodologies are oriented toward developing theoretical explanation through systematic and iterative engagement with data.
That makes the role of prior theory especially important. A highly prescriptive framework imposed before data collection could undermine a study that claims to develop its explanatory categories through grounded theory procedures.
At the same time, researchers do not enter grounded theory research without knowledge. Different grounded theory traditions handle prior literature, theoretical sensitivity, and existing concepts differently. The researcher should therefore follow the methodological tradition being used rather than relying on the simplistic instruction that grounded theory must either completely ignore theory or begin with a conventional theoretical framework.
Phenomenological research may use theory differently
Phenomenological traditions are concerned with experience and meaning, but they differ philosophically and methodologically. Some approaches emphasize careful attention to participants' lived experience without imposing an external explanatory framework too early. Others are informed by substantial philosophical traditions that shape how experience itself is understood.
Calling such work “theory-free” can therefore be misleading.
The researcher needs to distinguish a formal theoretical framework used to categorize the phenomenon from the philosophical and methodological assumptions underpinning the inquiry.
Critical and feminist approaches may make theory central
Other qualitative traditions explicitly employ theoretical perspectives because the research aims to examine structures and relations that may not be visible through surface description alone.
Critical, feminist, postcolonial, sociocultural, and related theoretical perspectives can influence what questions are considered consequential, whose experiences receive attention, and how apparently ordinary practices are interpreted.
Here, avoiding theory in the name of neutrality may itself conceal assumptions.
The relevant quality criterion is not whether theory disappears, but whether researchers make their theoretical position visible and use it reflexively.
Theory can enter primarily during analysis or interpretation
Not every study needs to commit strongly to one theoretical framework before data collection.
Researchers may begin with relatively open inquiry, develop empirical categories, and later examine how those findings relate to existing theoretical explanations. Theory can then help interpret patterns, explain surprising findings, compare cases, or connect the study with broader scholarship.
This can be particularly useful when the phenomenon is poorly understood and early theoretical specification might prematurely narrow inquiry.
Such work may be exploratory while still being theoretically informed. The crucial issue is transparency about when theory entered and how it affected the analysis.
Inductive analysis does not mean researchers have no prior concepts
Induction is sometimes presented as though researchers simply allow concepts to rise untouched from the data.
Qualitative analysis is more interpretive than that image suggests. Researchers decide what constitutes similarity and difference, how codes are named, which patterns matter, and how observations relate to broader concepts.
Reflexivity therefore matters. Rather than claiming to possess no theoretical assumptions, researchers can examine how their prior knowledge and conceptual commitments influence interpretation.
This is also why theory can enter iteratively. Researchers may move between empirical observations and existing explanations, revising both their interpretation of the data and their understanding of the theory.
A framework should influence the study if you claim that it guides the study
If you explicitly call something your theoretical framework, readers should normally be able to identify its role beyond the literature review.
Does it shape the research questions? Sampling? Interview guide? Observations? Coding? Interpretation? Discussion?
It does not need to control all of these. But if none of them changes because of the framework, its claimed role deserves reconsideration.
Green's discussion is instructive because the framework described in that qualitative case study was connected to research questions and data collection rather than being confined to a ceremonial framework section.
Theory should not erase findings that contradict it
Qualitative data may reveal experiences or processes that the selected theory cannot explain.
Those discrepancies can be theoretically valuable.
A theoretical concept may need refinement. The phenomenon may operate differently in the context studied. Another theoretical perspective may provide a stronger explanation. Participants may distinguish ideas that the theory treats as equivalent.
The researcher should therefore remain open to evidence that challenges the theoretical framework rather than treating theoretical conformity as a quality criterion.
A conceptual framework may sometimes be more appropriate
A qualitative study may draw on several concepts and bodies of literature without adopting one established explanatory theory.
A researcher-developed conceptual framework can organize those ideas and make the intellectual basis of the study explicit. Green's discussion also illustrates how conceptual frameworks can be incorporated throughout qualitative research and potentially contribute to subsequent conceptual development.
The distinction between theoretical and conceptual frameworks is not perfectly standardized, so researchers should define how they use the terminology and follow relevant disciplinary conventions.
Institutional requirements still matter
Your thesis handbook may require a theoretical framework even when your methodology would ordinarily use theory more flexibly.
That requirement cannot simply be ignored.
Discuss with your supervisor how the requirement is interpreted within your program. In some cases, the methodological or philosophical grounding of the study may satisfy part of what the institution calls a framework. In others, a conceptual or theoretical framework must be presented explicitly.
The objective should be to meet the reporting requirement without falsely claiming that a predetermined theory governed methodological decisions when it did not.
