Focus group interview (FGI) is a research technique based on the discussion of 8 - 12 people which utilizes the effects of group dynamics. During a joint discussion on the subject participants inspire, direct, and encourage one another to express their opinions, thereby allowing for receiving more information. The meeting is led by the moderator whose role is to guide the course of the discussion according to a script prepared before. During the meeting, participants refer to their personal experience and are treated as experts in a given field. The meeting is recorded and a transcription is created out of its recording. Then it becomes the subject of analysis.
