Multisystemic treatment (MST) Evidence – Based Treatment
The primary goals of MST are to:
- Reduce youth criminal behavior
- Reduce antisocial behavior, including substance abuse
- Achieve these outcomes at a cost savings by decreasing incarceration and out-of-home placement rates
Based on the philosophy that the most effective and ethical route to help youth is through helping their families, MST views parents or guardians as valuable resources, even when they have serious and multiple needs of their own. A "multisystemic" approach, however, views these youth as involved in a network of interconnected systems that includes individual, family, and extra-familial (e.g., peer, school, neighborhood) factors, and recognizes that intervention is needed across these systems.
