خلاصه	Open coding is the first, exploratory phase of qualitative data analysis in which raw text — interviews, field notes, or documents — is broken into discrete segments and labelled with short descriptive codes. Developed within grounded theory by Glaser and Strauss and later elaborated by Strauss and Corbin, the procedure is deliberately open and inductive: the analyst reads line-by-line without imposing a predetermined framework, allowing concepts to emerge directly from the data. The resulting codes are then compared and grouped into provisional categories that become the building blocks for subsequent, more selective analysis.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.	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.
