خلاصه	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.	Participant observation is a qualitative research method in which the researcher embeds themselves within a community, organization, or social setting for an extended period, engaging in the activities and relationships of the group while systematically observing and documenting behavior, interactions, and cultural meaning. Pioneered by Malinowski in the 1920s and developed in anthropology, the method has been adopted across sociology, education, health sciences, and organizational research. The researcher functions as both insider (participating in group activities) and outsider (maintaining analytical distance), generating thick description—rich accounts of context, behavior, and meaning that reveal how people actually live and interact.
