title: [Qualitative research: an introduction to focus group methodology and its application].
abstract: The focus group interview, an increasingly popular method in qualitative research, is used to obtain information that is highly accurate and relevant through a dynamic group interactive technique. Focus groups are used to gather ideas, opinions, perceptions, attitudes, and beliefs based on participants experiences in a defined area of interest. Focus groups can be used during the preliminary or exploratory stage of a study; during the course of a study (e.g., to develop or evaluate a particular / interesting program of activities); or after a program has been completed (e.g., to assess impact or generate further avenues of research). Focus group interviews can be used either as a method in their own right or as a complement to other methods, especially to check triangulation and validity. While our study concluded that focus group interviews are an "easy and cost efficient" method to collect quality data, validity and relationship issues between focus group data and other data must be determined and considered in the results. This article introduces the background, definitions, focus group process, participants, interview guidelines, moderator responsibilities, and data collection and analysis related to the focus group methodology.
