What Counts as Theory in Grounded Theory Research?
Why Is Theory Development Central to Grounded Theory?
Grounded theory was developed as an approach to generating theoretical explanations through systematic engagement with empirical material.
Glaser and Strauss's The Discovery of Grounded Theory emphasized the development of theory through comparative analysis rather than treating research exclusively as a process of testing existing explanations.
Later grounded theory traditions developed different philosophical orientations and analytical procedures, but theory development remains a defining methodological objective.
This distinguishes grounded theory from qualitative approaches whose primary purpose is to describe experiences, identify patterns, or interpret narratives without necessarily producing an integrated explanatory account.
Researchers should therefore establish whether grounded theory is appropriate for the research question before selecting it for its coding techniques.
What Does Theory Mean in Grounded Theory?
In grounded theory, theory generally refers to a conceptual explanation of a phenomenon or process developed through systematic analysis of empirical data.
It is not necessarily a grand theory intended to explain social behavior across every context.
A grounded theory may explain how people respond to a particular problem, how actions and interactions develop, or how conditions shape a social process.
For example, a theory of how instructors negotiate responsibility during AI-mediated assessment might explain how they recognize uncertainty, seek authority, adjust practices, and establish new expectations.
Theoretical value depends on how these concepts relate and what they explain.
Simply naming the stages does not establish a theory. The researcher must demonstrate why the stages or categories belong together, how the process operates, and what conditions influence it.
What Is a Substantive Grounded Theory?
A substantive grounded theory is developed in relation to a particular empirical area or substantive concern.
For example, a study might develop a theory explaining how first-year teachers negotiate classroom authority or how doctoral students manage repeated manuscript rejection.
The theory addresses a defined social or professional process rather than claiming universal applicability.
Glaser and Strauss distinguished substantive theory from formal theory. Formal theory addresses a more abstract conceptual area and may be developed through broader comparative work across substantive settings.
Most individual grounded theory research projects are more realistically oriented toward substantive theoretical contributions.
Researchers should not assume that a theory is inadequate because it is contextually situated or does not explain every possible variation of a process.
How Is a Grounded Theory Different From a List of Themes?
Themes identify patterns in qualitative material. A grounded theory develops conceptual categories and explains relationships among them.
Suppose a study of teachers' responses to AI identifies the following themes:
- Unclear institutional policies
- Concerns about professional responsibility
- Informal consultation with colleagues
- Changes in assessment practices
- Need for professional development
These themes may accurately summarize the interviews, but they do not yet explain how instructors negotiate responsibility.
A grounded theory analysis might investigate whether policy ambiguity leads instructors to seek informal authority, how professional risk shapes their decisions, and under what conditions new assessment practices become established.
These relationships would need to be developed through empirical comparison and theoretical analysis rather than assumed from the presence of the themes.
Descriptive themes
Patterns that organize what participants report or what the researcher interprets across qualitative material.
Grounded theoretical categories
Conceptually developed categories whose properties and relationships contribute to an explanatory account of the phenomenon.
The distinction is not that grounded theory uses more complicated terminology. The difference concerns conceptual integration and explanatory contribution.
What Is the Difference Between a Conceptual Framework, Model, and Theory?
Researchers sometimes use these terms interchangeably, but they do not necessarily refer to the same kind of analytical contribution.
A conceptual framework may organize relevant concepts or indicate how a researcher understands a problem. A model may represent proposed relationships or stages through a diagram or other structured representation.
A theory provides an explanatory account of relationships among concepts, including how or why a process operates under particular conditions.
These distinctions are not absolute. A conceptual model may communicate a grounded theory when its relationships are sufficiently developed and empirically supported.

The presence of arrows, boxes, or a named framework does not establish theory development. The explanatory relationships must be demonstrated analytically.
How Do Codes Become Categories and Categories Become Theory?
Grounded theory analysis commonly involves movement from close engagement with empirical incidents toward increasingly conceptual understanding.
Researchers compare incidents, develop codes, examine their similarities and differences, and refine categories through continued analysis.
Analytical memos help articulate category properties, possible relationships, and questions requiring further investigation.
Theoretical sampling then directs attention toward evidence capable of developing those categories and examining their relationships.
Eventually, the researcher seeks an integrated explanation that accounts for the process under investigation.
However, the exact sequence and terminology differ across grounded theory traditions.
Classic grounded theory emphasizes conceptual emergence and theoretical integration. Straussian approaches may use more explicitly articulated coding procedures. Constructivist grounded theory emphasizes interpretive construction and reflexive engagement with data.
Researchers should not assume that every grounded theory study must follow one universal sequence of open, axial, and selective coding.
What Makes a Category Theoretical Rather Than Merely Descriptive?
A descriptive category identifies an issue or type of experience. A theoretical category contributes to explaining a process through its properties, dimensions, conditions, and relationships with other categories.
For example, "institutional support" may be a descriptive category in a study of AI adoption.
Through grounded theory analysis, the researcher might develop a category such as "seeking authorization" to explain how instructors respond when responsibility for AI-mediated assessment is unclear.
The category could involve different forms of authorization, including formal policy consultation, informal advice, or independent justification.
The researcher would then investigate how this process relates to perceived professional risk, institutional authority, and subsequent assessment decisions.
These are hypothetical possibilities. They become theoretical findings only when supported through systematic comparison and analysis.
The key movement is from identifying a topic toward explaining what is happening and how it relates to the broader process.
Does Grounded Theory Require a Core Category?
The role of a core category depends on the grounded theory tradition.
Classic grounded theory places considerable emphasis on identifying a core category that integrates other categories and helps explain the central concern or process.
Other approaches also emphasize theoretical integration, although they may conceptualize the central organizing category differently.
A researcher should not invent a core category simply because a methodology chapter expects one.
The central category should be developed through analysis and demonstrate explanatory relevance to the other categories.
Likewise, identifying one frequently mentioned theme does not automatically establish it as the core category.
The relevant question is whether the category helps integrate and explain the emerging theoretical account.
Why Is Theoretical Sampling Necessary for Theory Development?
Theoretical sampling allows researchers to pursue questions generated by emerging analysis.
Suppose an initial category suggests that instructors seek informal advice when institutional AI policies are unclear.
The researcher might seek additional participants or situations involving clearer policies to examine whether the same process occurs under different conditions.
This comparison could refine the category or challenge the emerging explanation.
Theoretical sampling is therefore not merely a recruitment strategy. It is part of the process through which theoretical categories are developed.
A study that collects all interviews according to a fixed plan and conducts analysis only afterward may have limited opportunity to pursue emerging theoretical relationships.
Researchers should explain how theoretical sampling contributes to category development rather than treating it as a synonym for purposive recruitment.
What Does Constant Comparison Contribute to Theory Development?
Constant comparison supports the development of conceptual distinctions and relationships.
Researchers compare incidents within and across accounts, examine differences in how categories appear, and investigate conditions that may influence actions or interactions.
For example, an instructor who independently changes assessment practices may be compared with another who seeks departmental authorization.
The researcher might investigate whether the difference relates to professional status, perceived risk, policy clarity, or other conditions suggested by the data.
Such comparisons can help refine categories and develop a more explanatory account.
Constant comparison should not be reduced to checking whether multiple participants report the same issue.
Its contribution lies in progressively developing conceptual understanding.
How Important Is Memo-Writing for Producing a Theory?
Memo-writing is central to the analytical development of grounded theory.
Memos allow researchers to record emerging concepts, examine relationships, question assumptions, and identify directions for further data collection.
For example, a memo may explore whether "seeking authorization" is a response to institutional uncertainty or part of a broader process of negotiating professional accountability.
Later comparisons may support, refine, or challenge that interpretation.
Without sustained analytical memo-writing, researchers may struggle to explain how they moved from initial codes to an integrated theory.
Memos are not simply records of interview dates or procedural activities. They are working documents through which theoretical reasoning develops.
What If the Study Produces Only a Preliminary Theory?
Not every grounded theory project achieves the same degree of conceptual development.
Practical constraints, limited access to participants, insufficient variation in the data, or emerging analytical questions may prevent a study from developing a fully integrated explanation.
In such cases, researchers should distinguish between a preliminary theoretical account and a completed grounded theory.
A preliminary account may identify promising categories and possible relationships while acknowledging that further theoretical sampling and comparison are needed.
Such work can still contribute to knowledge when its limitations are clearly reported.
However, describing a set of underdeveloped categories as a fully established theory would overstate the findings.
Researchers should explain what has been developed, what remains uncertain, and what additional investigation would be needed.
Can a Grounded Theory Study Fail to Produce a Theory?
Yes. Research projects do not always achieve their intended methodological outcomes.
A study may begin with a grounded theory design but fail to develop sufficiently integrated theoretical categories.
This may occur because the research question was too descriptive, data collection did not respond to emerging categories, or the analysis stopped after initial coding.
It may also occur because the available evidence does not support the proposed explanatory relationships.
The appropriate response is not to invent a theory or attach a theoretical label to ordinary themes.
Researchers should report the actual analytical contribution and consider whether the study is better characterized as exploratory qualitative research, qualitative description, or research informed by grounded theory techniques.
Such a decision should be transparent and consistent with the procedures followed.
Does Theoretical Saturation Guarantee That a Theory Is Complete?
No. Theoretical saturation is an important concept in grounded theory, but it should not be treated as a mechanical guarantee of theoretical completeness.
Different grounded theory traditions conceptualize saturation differently. Researchers may consider whether categories are sufficiently developed, whether their properties and relationships have been explored, and whether additional comparisons are producing significant theoretical insights.
Simply reaching a point where no new interview topics appear is not equivalent to theoretical saturation.
Nor does the declaration of saturation establish that the resulting theory is coherent or adequately grounded.
Researchers should explain what was assessed and how the stopping decision relates to the selected methodology.
Theoretical adequacy depends on the quality of category development and integration, not merely on the number of interviews completed.
How Should a Grounded Theory Be Presented in the Findings?
The findings should communicate the explanatory account rather than simply reproduce a coding framework.
A grounded theory report may present a central process, its conceptual categories, relationships among categories, and the conditions under which the process varies.
A diagram can be useful when it clarifies those relationships, but the accompanying explanation remains essential.
Researchers should demonstrate how the categories were developed through analysis and provide empirical material supporting the interpretation.
The report should also acknowledge contextual boundaries and areas of uncertainty.
For example, a theory developed from university instructors' accounts of AI-mediated assessment should not automatically be presented as explaining every form of AI adoption across education.
The explanatory scope must remain proportionate to the empirical and analytical basis of the study.
