[Focus group interview. A method of study and implementation].
INTRODUCTION: The aim of this article is to present the qualitative focus group interview as a useful method of evaluating psycho- and milieu therapeutic treatment. MATERIAL AND METHODS: We conducted two focus group interviews with former inpatients of a psychiatric ward specialising in group therapy. To enhance the quality of the data by triangulation, the staff, representing both milieu- and psychotherapists, were also interviewed. RESULTS: Analysis of the results revealed the following dominant themes: The continuation of the treatment was jeopardised by the existence of a welcome group. There was a need for further information as soon as the patient came into contact with the hospital. Moreover, an earlier and increased involvement of the family was required. After their own interview, the staff participated in deciding which results should lead to alterations in treatment procedures, thereby becoming involved in implementing the results. DISCUSSION: The focus group interview is a valuable method of evaluating psycho- and milieu therapeutic treatment. Interviewing the staff served as triangulation and eased the implementation of the results remarkably.
