Podsumowanie	A triangulated semi-structured interview strategy combines the flexibility of open-ended, guided interviewing with deliberate triangulation across multiple informant groups, data sources, or interview occasions. By applying the same semi-structured protocol to different participant perspectives — such as clients, providers, and managers — or by pairing interviews with documents and observations, the approach cross-validates emerging themes and reduces the risk that any single viewpoint dominates the findings. The result is richer, more credible qualitative data than a single-source interview study can deliver.	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.
