Economic Impact of the Statewide Implementation of an Evidence-Based Treatment: Multisystemic Therapy in New Mexico.

Several states have made considerable investments into large-scale implementation of evidence-based treatments (EBTs), yet little is known about key success indicators for these implementation efforts such as cost and sustainability. To that end, the present study examined the economic impact of statewide implementation of multisystemic therapy (MST; Henggeler, Schoenwald, Borduin, Rowland, & Cuningham, 2009), a family- and community-based behavioral EBT for serious juvenile offenders in New Mexico. Participants were 1,869 youth who received MST across 23 teams during the study period.
