Focus group: implications for program evaluation of mental health services.

The focus group is a qualitative research method that involves group interaction based on a selected topic. It generally involves eight to 12 individuals who discuss a particular topic under the direction of a moderator who promotes interaction and guides the discussion on the topic of interest. This paper presents theoretical perspectives and a review of focus group methodology applied in related disciplines. A research project, which applied the focus group methodology, is described to illustrate important principles in utilizing this qualitative research technique. Information related to preparation for focus group sessions, structure, setting, participants, principles related to conducting the session and analysis are presented. The relevance of this methodology for research and practice in mental health also is discussed.
