How does the delivery of multisystemic therapy to adolescents and their families challenge practice in traditional services in the Criminal Justice System?

Multisystemic therapy (MST) is described and contrasted with practice in traditional services for young people who have committed crime, behaved anti‐socially, abused substances or suffered family conflict. The challenges to traditional services posed by MST are examined, including consideration of the process of engagement in therapy, the intensive individualised therapy delivered in the young person's own home or local community, and the quality assurance systems.
