Multisystemic Therapy (MST)

MST is a pragmatic, goal-oriented, family- and community-based treatment that addresses the causes of serious anti-social behavior in youth who are at high risk for out-of-home placement. MST focuses on the factors associated with major behavioral problems in the key systems in youths’ lives: their families, their peer networks, their schools, and their neighborhoods. Using the strengths of each system to foster positive change, MST promotes behavior change in youths’ natural environments. MST mobilizes individual, family, and community resources to support and maintain behavioral change.

Multisystemic Therapy for Youth with Problem Sexual Behaviors (MST-PSB) is a clinical adaptation of MST that has been specifically designed and developed to treat youth (and their families) for problematic sexual behavior.
