สรุป	The multi-source focus group method extends the standard focus group design by deliberately recruiting participants from two or more distinct stakeholder groups — for example, clinicians and patients, teachers and students, or managers and frontline staff. Separate sessions are held for each source group using a shared discussion protocol, and the resulting data are analyzed both within each group and across groups to reveal convergences, tensions, and perspectives that no single-source design could uncover.	Focus group research is a qualitative data-collection method in which a trained moderator guides structured discussions with homogeneous groups of six to ten participants to explore ideas, attitudes, and perceptions on a defined topic. Developed from sociological roots in the 1940s and systematised for applied research by Krueger and Casey, the method leverages group interaction as a data source — revealing not just what people think, but how they negotiate and articulate views in a social setting.
