This document discusses different qualitative research methodologies and choosing the appropriate one. It considers phenomenology, ethnography, and grounded theory as options. Grounded theory is selected for a study on how South Asians choose and prioritize lifestyle changes because it aims to explain how social circumstances influence behaviors and experiences, moving beyond just describing experiences. The document also discusses choosing between different versions of grounded theory, ultimately selecting Charmaz's approach due its compatibility with the study through concepts like multiple realities, the literature review, and ensuring participant voices are included.
