Engaging multiproblem families in treatment: lessons learned throughout the development of multisystemic therapy.

Multisystemic therapy (MST) is a family-based treatment model that has achieved high rates of treatment completion with youths who present serious clinical problems, and their families. The success of MST in engaging challenging families in treatment is due to programmatic commitments to family collaboration and partnership as well as to a conceptual process that delineates barriers to family engagement, develops and implements strategies to overcome these barriers, and evaluates the success of these strategies. This article provides an overview of the nonspecific/universal engagement strategies used by MST therapists, frequently observed barriers to achieving therapist-family engagement, and specific strategies to overcome a sampling of these barriers.
