สรุป	Field-based grounded theory integrates sustained fieldwork — participant observation, field notes, and naturalistic data collection — with the iterative coding and theoretical sampling procedures of classic grounded theory. Where standard grounded theory typically relies on interview transcripts, the field-based variant anchors theory generation in direct, prolonged observation of naturally occurring social processes in context. The result is a substantive theory that is grounded in both what people say and what they actually do in their everyday settings.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.	Narrative analysis is a qualitative research method, synthesised canonically by Catherine Kohler Riessman (2008), that examines how individuals storise their lived experiences and construct meaning through the telling. Drawing on life history, biographical, and narrative inquiry traditions, it treats the story itself — not just its content — as the unit of analysis, attending to temporal sequence, plot structure, and the social context in which a narrative is produced.
