Interpretive Grounded Theory
Also known as: interpretivist grounded theory, constructivist grounded theory, IGT, grounded theory — interpretivist strand
Interpretive grounded theory is a qualitative methodology that builds substantive theory inductively from data while working from an interpretivist epistemological stance. Developed most fully by Kathy Charmaz, it holds that researcher and participant co-construct meaning, that categories are created rather than discovered, and that the resulting theory is one plausible account among others rather than an objective rendering of social reality.

When to use it
Choose interpretive grounded theory when the research aim is to build a theoretical account of a process, experience, or social phenomenon from the ground up, and when the researcher works from an interpretivist or constructivist epistemology — acknowledging that knowledge is situated and meaning is co-constructed. It is appropriate for phenomena that lack adequate existing theory, or where available theories do not fit the population or context at hand. Data must be primarily textual (interview transcripts, field notes, documents); the method is not suited to numerical datasets. Do not choose it if the aim is to describe the frequency of themes, to test an existing theory, or to produce a narrative portrait rather than a theoretical model — phenomenology, case study, or thematic analysis will then be more appropriate.
Strengths & limitations
- Produces original theoretical accounts of social processes rather than merely describing themes.
- Iterative theoretical sampling keeps data collection tightly linked to emerging analysis, maximising conceptual yield.
- The interpretivist stance foregrounds reflexivity, making the researcher's influence on findings transparent rather than concealed.
- Well-suited to under-theorised phenomena where existing frameworks poorly fit the study population or context.
- Flexible across disciplines — used in health sciences, sociology, education, management, and social work.
- Generating a credible grounded theory requires substantial data, time, and analytic skill; it is not a quick method.
- Theoretical saturation — the endpoint criterion — is difficult to operationalise and is often under-achieved in practice.
- The resulting theory is context-specific and mid-range; it does not aspire to broad statistical generalisability.
- Decisions about coding and categorisation remain interpretive; two researchers working on the same data may produce different theories.
Frequently asked
What distinguishes interpretive grounded theory from constructivist grounded theory?
In most of the literature the two labels describe the same epistemological position — Charmaz's own term is 'constructivist grounded theory', and it is the canonical label. 'Interpretive grounded theory' is a broader descriptor used by researchers who affiliate with interpretivism without necessarily citing Charmaz directly. In practice, both terms signal a rejection of the objectivist assumptions of classic Glaserian grounded theory and an acceptance that the researcher actively shapes the categories produced.
How is interpretive grounded theory different from thematic analysis?
Both use inductive coding of qualitative data, but the goals differ. Thematic analysis aims to identify and describe patterns or themes across the dataset. Interpretive grounded theory aims to produce a theory — a conceptual explanation of a process or relationship, not just a list of themes. Grounded theory also requires theoretical sampling and memoing, neither of which is part of standard thematic analysis.
When has theoretical saturation been reached?
Saturation is reached when additional data collection and coding are no longer producing new conceptual categories or modifying the relationships among existing ones. In practice, researchers often set a provisional target (e.g., 20–30 interviews) and then conduct a few extra to confirm saturation. The interpretivist position acknowledges that saturation is a judgement call, not a mechanical endpoint.
Can I use software such as NVivo or ATLAS.ti?
Yes — qualitative data analysis software is widely used in grounded theory studies for managing data, storing memos, and organising codes. The software does not do the analytic or theoretical work; coding decisions, memo writing, and conceptual integration must be performed by the researcher. Software handles logistics; theory-building remains human work.
How large should the sample be?
Sample size is determined by theoretical sampling logic rather than a preset number. Most published interpretive grounded theory studies use between 15 and 40 participants, but the criterion is theoretical saturation, not a fixed n. Starting with a smaller purposive sample and expanding based on emerging conceptual needs is the methodologically appropriate approach.
