สรุป	Longitudinal ethnography is a qualitative research design in which a researcher conducts sustained, repeated fieldwork with the same community, organisation, or group across an extended period — months to decades. By returning to the field at multiple time points, the researcher captures how social processes, meanings, and structures evolve, making it the only qualitative method capable of directly observing change and continuity in lived experience.	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.
