Recidivism risk reduction assessment in batterer intervention programs: A key indicator for program efficacy evaluation

Abstract

The evidence available on the efficacy of batterer intervention programs is still limited. The aim of the present study is twofold: (1) to analyze change in a set of intervention targets and their association with reconviction in a batterer intervention program implemented in Spain, and (2) to analyze pre-treatment participants’ characteristics linked with an increased likelihood of change. The research design was a prospective longitudinal study with measures obtained in two points in time (pre-treatment and post-treatment). Self-report measures, trained program staff assessment, and reconviction official records were used. Participants consisted of 212 offenders participating in a court-mandated batterer intervention program. A significant gain in three intervention targets (responsibility assumption, perceived severity of intimate partner violence against women, and recidivism risk reduction) was found. Recidivism risk reduction gain score was the best success indicator. It significantly predicted reconviction with the highest effect size. A structural equation model showed that recidivism risk reduction was significantly predicted by pre-treatment offenders’ anger control, impulsivity, social support, alcohol consumption, and offense seriousness. Participants changed in the intervention targets analyzed and risk of recidivism reduction played a central role in the prediction of reconviction.
