Multisystemic Therapy (MST)

 Multisystemic therapy (MST)

Multisystemic therapy (MST) is a family-and community-based treatment for youths presenting serious antisocial behavior and their families. Based on favorable long-term outcomes (e.g., reduced criminal behavior, drug use, and out-of-home placements) achieved in several rigorous evaluations, MST has received accolades from numerous federal (e.g., U.S. Surgeon General, National Institutes of Health, Center for Substance Abuse Treatment) and private (e.g., Annie E. Casey Foundation) entities and academic reviewers.

Favorable MST outcomes have been achieved by:

  • Addressing known risk factors, while building protective factors
  • Staying strength focused
  • Viewing caregivers as the keys to obtaining favorable outcomes for their youths
  • Using a home-based model of service delivery to overcome barriers to service access and provide treatment where problems actually occur – in home, school, and community settings
  • Surrounding practitioners with a strong and state-of-the-art quality assurance system to promote treatment fidelity
  • Integrating evidence-based intervention techniques, primarily from the behavior therapies, cognitive behavior therapies, and pragmatic family therapies
