Impact evaluation and economic benefit analysis of a domestic violence and abuse UK police intervention.
Frontiers in psychology(2023)
摘要
This study evaluated the impact and economic benefit of Cautioning and Relationship Abuse (CARA), an intervention which aims to reduce re-offending of first-time low-level domestic violence and abuse perpetrators. The analysis was based on two samples drawn from separate UK police force areas. CARA's impact was assessed using a matched sample of similar offenders from a time when CARA was not available. The matching was based on a host of offender and victim characteristics and machine learning methods were employed. The results show that the CARA intervention has a significant impact on the amount of recidivism but no significant reduction in the severity of the crimes. The benefit-cost ratio in both police force areas is greater than one and estimated to be 2.75 and 11.1, respectively, across the two police force areas. Thus, for each pound (£) invested in CARA, there is an economic benefit of 2.75-11.1 pounds, annually.
