Multisystemic therapy (MST) is an intensive, family-centered treatment approach designed to address the various factors influencing juvenile delinquency. It focuses on the interconnectedness of multiple systems in a young person's life, such as family, peers, school, and community, to create positive behavioral change. By working with the entire ecosystem surrounding the youth, MST aims to improve family relationships and enhance the youth's support systems to prevent further delinquent behavior.
