Family-inclusive approaches in the context of a dual diagnosis: A systematic review of relational and individual wellbeing outcomes

Résumé fourni par la source

OBJECTIVE: For many, ill mental health and alcohol or other drug problems go hand in hand, resulting in complex presentations requiring specialised approaches. This review summarises recent evidence on the efficacy of family-inclusive approaches in the treatment of patients with a dual diagnosis. METHOD: A systematic search of five databases from January 2000 to February 2026 yielded 12,776 records, with 28 meeting inclusion criteria. RESULTS: Included studies reported on two distinct cohorts: adolescents, presenting with a mental health diagnosis and substance use, and adult clients, predominantly in hospital care due to a severe mental health condition paired with serious substance use of often more than one substance. In both cohorts, most studies found family-inclusive treatment approaches performed as well or better than treatment-as-usual for underlying conditions and for global and family functioning (adolescents, adults), family conflict, parental skills and family communication (adolescents). DISCUSSION: The intertwining of two serious health conditions is particularly challenging for practitioners, families and clients alike. Our findings show that family-inclusive interventions not only improve relational wellbeing of clients with their families but also have a positive impact on both mental health and substance use related conditions. By identifying effective ways of integrating families in treatment and highlighting gaps and further needs, these findings may assist the field to further prioritise family-inclusive approaches, and the added leverage they offer in the life of those facing complex health challenges.
