THE PREVENTIVE EFFECTS OF ARREST ON INTIMATE PARTNER VIOLENCE: RESEARCH, POLICY AND THEORY*

Research Summary: This research addresses the limitations of prior analyses and reviews of five experiments testing for the specific deterrent effect of arrest on intimate partner violence by applying to individual level data consistent eligibility criteria, common independent and outcome measures, and appropriate statistical tests. Based on 4,032 cases involving adult males who assaulted their female intimate partners, multivariate regression analyses show consistent but modest reductions in subsequent offenses targeting the original victim that is attributable to arresting the suspect. Although the reductions attributable to arrest are similar across all five studies, other factors, such as the suspect's prior arrest record, are stronger predictors of subsequent offenses. The effect of arrest is also modest compared with the general decline in offenses toward the same victim during the follow-up period. Policy Implications: These results lend limited support for policies favoring arrest over informal police responses to intimate partner violence. However, the analyses also show that despite police intervention, a minority of suspects repeatedly victimize their partners and that factors other than formal sanctions play larger roles in explaining the cessation or continuation of aggressive behavior between intimates. These findings suggest that new policies replacing or enhancing arrest that target potential repeat offenders might produce larger reductions in intimate partner violence.
