Individual Placement and Support for first episode psychosis

Adult Mental Health: Serious Mental Illness
  Literature review updated August 2017.

Studies in this review examined integrated treatment approaches for adolescents and young adults experiencing a first episode of psychosis. Intervention periods lasted between 9 and 24 months. Integrated treatment typically included making 3-4 of the following components available to patients: Assertive community treatment and case management, cognitive behavioral therapy for psychosis, social skills training, and family support/psychoeducation. Both treatment and comparison groups were offered anti-psychotic medication as indicated. In this review, integrative treatment is compared with treatment as usual through community mental health clinics.

META-ANALYSIS
CITATIONS

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.
