What distinguishes the method of grounded theory from other qualitative research methods?

Grounded theory is distinct because it emphasizes the development of theory directly from the data that is collected during the research process. This method allows researchers to emerge with conceptual frameworks or theories grounded in the reality of the studied phenomenon, as opposed to starting with an existing theory and attempting to fit the data into it. This iterative process involves collecting data, coding it, and constantly comparing new findings with existing data to refine and develop theoretical insights throughout the study.

In contrast, relying on pre-existing theories is characteristic of other qualitative methods, which may start with established frameworks and apply them to analyze various data. The notion that grounded theory requires large sample sizes is not accurate, as it often utilizes a more focused, selective sampling strategy to develop rich, in-depth understanding, and it adapts sample size based on data saturation. Finally, grounded theory focuses on qualitative data, not quantitative measurements, which does not align with its core principles that aim to explore and understand complex social phenomena through subjective interpretations and meanings.
