Effectiveness of psychological treatments for violent offenders in custodial, community and forensic mental health settings: A systematic review and meta-analysis
Overview
This 2018 systematic review and meta-analysis examined psychological treatments for violent offenders across custodial, community, and forensic mental health settings. Analyzing 27 studies from 1993-2017, researchers found psychological treatments effective in reducing violent and general reoffending by approximately 10-11%. High-intensity, multi-component treatments including relapse prevention, role playing, and homework showed greatest impact. The review supports psychological interventions for violent offenders but notes limited high-quality studies in community and forensic settings.
