Effectiveness of a Prison-Based Treatment Program for Male Perpetrators of Intimate Partner Violence: A Quasi-Experimental Study of Criminal Recidivism

Abstract

Despite increasing interest in programming for perpetrators of intimate partner violence (IPV), the literature provides weak support for the effectiveness of these interventions. However, there are few studies that evaluate programs offered to felony IPV offenders who are serving prison sentences. This study uses a quasi-experimental design to evaluate the effectiveness of a prison-based implementation of a popular IPV intervention in reducing general and offense-specific recidivism among 169 men released from state prison in 2017. Because recidivism data were collected through early March 2019, the average follow-up period was approximately 20 months for both the control group and experimental group. Observable selection bias was minimized by using propensity score matching to create a comparison group of 169 nonparticipants released in 2017 who were not significantly different from the program participants. Cox regression models were used to predict general rearrest, reconviction, reincarceration, and supervised release revocation, as well as rearrest and reconviction for any violent offenses and rearrest and reconviction for domestic violence offenses in particular. No significant differences in any type of recidivism were found between the comparison group and those who participated in treatment, regardless of whether the participant completed or failed to complete the program. The findings suggest that the intervention is no more successful when offered within prisons than when offered in the community. The study concludes by making recommendations for increasing the effectiveness of prison-based domestic violence programming.
