Multisystemic Therapy (MST) is a time-limited, intensive family intervention intended to stabilize the living arrangement, promote reunification, or prevent and reduce the utilization of out-of-home therapeutic resources. This approach focuses on the natural environment of the child and family and strives to change how the child functions within the context of his/her home, school, neighborhood and peer group. A major emphasis of MST is to empower the parents of caregivers with the skills and resources needed to become independent in addressing the difficulties that arise in raising adolescents, and to assist the youth in developing life-long coping skills. Therapists are on-call for their families 7 days per week around the clock. Each therapist carries a small caseload (4 to 6 families at any one time). For weekends, a 24-hour on-call system is active, with supervisory staff on as back-up to support the primary on-call therapist.
