This study investigates therapeutic factors of a Family Support Group (FSG) intervention for family members of mentally ill offenders. Seventeen family members completed the 'Group Therapeutic Factors-Client Questionnaire' (GTF-CQ-28) during four sessions of two FSGs. Results indicate that family members experienced the following therapeutic factors over the course of treatment: the relational climate, interactional confirmation, expressing and experiencing mutual positive feelings, forgetting own problems, hope from seeing progress in others, guidance from therapists, and getting interpersonal feedback treatment. The therapeutic factors, including learning by observation, support from the group, and universality of problems, correlated with a decrease in selfblame, improved emotional well-being, and experiencing less loss of control over one's life, respectively. Further, family members were satisfied with what the FSG has provided for them personally and for the relation with their relative. Finally, clinical implications of the FSG are discussed. The study sheds light on valuable therapeutic factors within an FSG and the important role of therapists.
Key Points1 Family members who have a relative that is a mentally ill offender are often doubly stigmatised because of the latter's psychiatric problems and the criminal offences committed, which cause manyburdens that need to be addressed by others (friends, family members, or professionals). 2 Family Support Groups (FSGs) are based on Multi-Family Group therapy to support and empower family members of mentally ill offenders. 3 It is important for practitioners to know and focus on helpful therapeutic factors underlying an FSG including group support, similarity with others, and therapeutic guidance to empower and support family members in dealing with their situation. 4 Within forensic psychiatry there is a dearth of family interventions to support family members of mentally ill offenders, especially those that focus on family members, and this is also not yet addressed in research. 5 Focusing on treatment improvement is valuable in looking at the impact the FSG has on family members' coping strategies and burdens; FSG is a valuable therapy for family members to relieve burdens and to reduce feelings of self-blame.
