The Impact of Known Criminals on the Proportion and Seriousness of Intimate Partner Violence Incidents

Abstract

This study examines a hypothesis that has not received adequate scrutiny: that an important proportion of intimate partner violence (IPV) incidents, particularly those that are more serious, involve generalist offenders known to the police. Many criminological theories and empirical studies suggest that offenders are often generalists, yet few IPV studies consider this hypothesis. Based on a sample of 52,149 IPV incidents recorded by police, we found that 31% of IPV incidents involved suspects only with criminal records for non-IPV criminality, 9% involved victims only with criminal records for non-IPV criminality, and 14% involved both suspects and victims with criminal records for non-IPV criminality. Thus, 45% of IPV offenders and 23% of IPV victims had criminal records for non-IPV criminality. Multilevel regression analyses reveal that controlling for prior IPV incidents, community context, and other individual and couple variables, IPV offenders with criminal records are 16% more likely to be involved in more serious incidents, and victims of IPV with criminal records are 17% more likely to be involved in more serious incidents. In addition, IPV incidents for which both suspects and victims had criminal records were 46% more likely to be more serious incidents. These results suggest that generalist criminals known by police have an important impact on the proportion of IPV incidents, particularly the more serious ones.
