Multisystemic Therapy (MST) is a scientifically proven intervention for at-risk youth. Therapists work in the home, school, and community and are on call 24/7 to provide caregivers with the tools they need to transform the lives of troubled youth. Research demonstrates that MST reduces criminal activity and other undesirable behavior. At the close of treatment, 87% of youth have no arrests. MST is continuing services during the COVID-19 pandemic through social distancing and telehealth methodologies such as telephone and/or video-based training and interventions. MST currently operates in 34 states and 15 countries with 2,500+ clinicians. Over 200,000 families have been positively impacted by MST. With 70+ studies, MST features the largest body of evidence, by far, of successful interventions for high-risk youth.
