The Effectiveness of Intimate Partner Violence Interventions by the Police, Prosecutors, and Courts

The criminal justice system (CJS), comprising police, prosecutors, and courts, is pivotal in preventing intimate partner violence (IPV). However, challenges persist in effectively protecting victims, with high post-reporting recidivism rates. This systematic review aims to identify CJS interventions targeting IPV recurrence and to assess their effectiveness. Eleven articles meeting inclusion criteria were categorized into three themes: police (five articles), prosecutor (zero articles), and court (six articles). While overall findings lack conclusive evidence on intervention effectiveness, they suggest potential in reducing IPV recidivism among specific perpetrator sub-groups. The review underscores the need to consider contextual factors when evaluating interventions like arrest for IPV prevention. Challenges in identifying evidence-based practices within the CJS persist, necessitating ongoing evaluation research and investment in evidence-based strategies to inform policy and practice effectively.
