สรุป	An unstructured interview is a qualitative data-collection method in which the researcher enters the conversation with a broad topic or grand-tour question rather than a fixed questionnaire, allowing the participant to direct the flow and depth of the discussion. The approach prioritises the participant's own conceptual categories and narrative logic over the researcher's pre-formed agenda, making it especially powerful for exploratory inquiry into unfamiliar or complex social phenomena.	Thematic Analysis (TA) is a qualitative research methodology for identifying, analyzing, and reporting patterns (themes) in qualitative data. Developed systematically by Virginia Braun and Victoria Clarke (2006), TA is flexible and accessible, applicable across diverse theoretical frameworks and data types, making it one of the most widely used qualitative methods in psychology, health research, and social sciences.
