Sintesi	A face-to-face focus group is a structured, moderated group discussion conducted in a shared physical space, typically with 6–10 participants who are selected because they share a relevant characteristic. The moderator follows a semi-structured topic guide to elicit opinions, perceptions, and experiences. Unlike surveys, focus groups capture social interaction — agreement, disagreement, and the group dynamics through which attitudes are formed and expressed.	A face-to-face semi-structured interview is a qualitative data collection technique in which a researcher meets a participant in person and follows a prepared topic guide of open-ended questions while retaining the flexibility to probe, reorder, and explore emerging themes. It combines the consistency of a predetermined agenda with the depth and responsiveness of an open dialogue, making it one of the most widely used methods in qualitative and mixed-methods research across the social, health, and educational sciences.
