Intimate Partner Violence and Subsequent Violent Offending Among Handgun Purchasers.

Perpetrators of intimate partner violence (IPV) often reoffend, and firearm access increases risk of severe injury or fatality. Prior research identifies an association between a history of violent misdemeanor convictions among handgun purchasers and increased risk of subsequent arrest for a violent crime; the risk associated specifically with an IPV criminal history remains largely unexplored. The current study examined a cohort of 76,311 California adults who legally purchased a handgun in 2001 and followed them through 2013. Compared with purchasers who had no criminal history at the time of purchase, those with a history of only IPV ( = 178) charges were at increased risk of subsequent arrest for a violent Crime Index crime (murder, rape, robbery, aggravated assault; adjusted hazard ratio [AHR], 2.6; 95% confidence interval [CI]: 1.4-5.1), any violent crime (AHR, 3.2; 95% CI: 2.0-5.1), and an IPV crime (AHR, 5.2; 95% CI: 3.0-9.0). Purchasers with both IPV and non-IPV charges demonstrated the greatest risk of re-arrest relative to those with no criminal history. Despite the strength of the relationship between IPV and subsequent arrest, a small proportion of handgun purchasers with an IPV criminal history were re-arrested for firearm violence crimes, limiting application for risk assessment purposes. Results affirm prior research identifying IPV as a risk factor for future offending.
