Multisystemic Therapy (MST) is an intensive family- and community-based treatment, which combines aspects of cognitive, behavioral, and family therapies. The purpose of MST is to reduce juvenile delinquency and youth substance use and empower parents to manage future difficult behavior. Children with serious emotional disturbance are most often referred to MST by child welfare agencies, juvenile courts, and schools. MST therapists provide individualized treatment in a child’s home, school, or community for an average of five months. These therapist-led sessions aim to modify the youth’s environment to support lasting behavioral changes through goal-setting, weekly treatment tasks, and progress monitoring. MST is often conducted with court-involved youth as a requirement of their adjudication; however, the studies included in this analysis primarily focused on children with serious emotional disturbance either without or prior to adjudication.

 

Meta-analysis is a statistical method to combine the results from separate studies on a program, policy, or topic to estimate its effect on an outcome. WSIPP systematically evaluates all credible evaluations we can locate on each topic. The outcomes measured are the program impacts measured in the research literature (for example, impacts on crime or educational attainment). Treatment N represents the total number of individuals or units in the treatment group across the included studies.

An effect size (ES) is a standard metric that summarizes the degree to which a program or policy affects a measured outcome. If the effect size is positive, the outcome increases. If the effect size is negative, the outcome decreases. See Estimating Program Effects Using Effect Sizes for additional information on how we estimate effect sizes.

The effect size may be adjusted from the unadjusted effect size estimated in the meta-analysis. Historically, WSIPP adjusted effect sizes to some programs based on the methodological characteristics of the study. For programs reviewed in 2024 or later, we do not make additional adjustments, and we use the unadjusted effect size whenever we run a benefit-cost analysis.

Research shows the magnitude of effects may change over time. For those effect sizes, we estimate outcome-based adjustments, which we apply between the first time ES is estimated and the second time ES is estimated. More details about these adjustments can be found in our Technical Documentation.
