Family group conferences are usually organized in youth care settings, especially in cases of (sexual) abuse of children and domestic violence. Studies on the application of family group conferences in mental health practices are scarce, let alone in a setting even more specific, such as public mental health care. The present study reports on an exploratory study on the applicability of family group conferencing in public mental health care. Findings suggest that there are six reasons to start family group conference pilots in public mental health care. First, care providers who work in public mental health care often need to deal with clients who are not motivated in seeking help. Family group conferences could yield support or provide a plan, even without the presence of the client. Second, conferences might complement the repertoire of treatment options between voluntary help and coercive treatment. Third, clients in public mental health care often have a limited network. Conferences promote involvement, as they expand and restore relationships, and generate support. Fourth, conferences could succeed both in a crisis and in other non-critical situations. Sometimes pressure is needed for clients to accept help from their network (such as in the case of an imminent eviction), while in other situations, it is required that clients are stabilized before a conference can be organized (such as in the case of a psychotic episode). Fifth, clients who have negative experiences with care agencies and their representatives might be inclined to accept a conference because these agencies act in another (modest) role. Finally, the social network could elevate the work of professionals.
