Grounded theory research typically involves how many individuals?

Grounded theory research typically involves engaging with a sample size that allows for in-depth analysis and the emergence of a substantive theory. This often means including around 20 to 30 individuals, as this range strikes a balance between gathering diverse perspectives and maintaining the ability to conduct thorough qualitative analysis.

In grounded theory, the goal is to develop a theory that is grounded in the data collected from participants. A sample size of 20 to 30 individuals is generally sufficient to identify patterns, explore relationships, and reach saturation—where no new information or themes emerge from further data collection. This quantity allows researchers to ensure a rich and nuanced understanding of the phenomenon being studied.

Smaller groups, such as 1 to 5 individuals, may not provide enough diversity of viewpoints to develop a robust theory, while significantly larger groups can complicate the analysis and detract from the detailed examination of individual experiences. Consequently, the choice of 20 to 30 individuals aligns well with the methodological tenets of grounded theory, where depth and richness are paramount.
