Background: Intimate partner violence (IPV) is a significant public health problem with many negative consequences, particularly for pregnant women. This randomized trial investigated the effectiveness of an IPV preventive intervention embedded within the Nurse Family Partnership (NFP) program., Materials and Methods: Participants enrolled over a 20-month period and were interviewed at baseline and 1- and 2-year follow-up. Eligibility criteria included first pregnancy, eligible for the nutrition program Women, Infants, and Children (WIC), English or Spanish speaking, and at least 15 years of age. All women initially referred and screened were randomized to either intervention (NFP+) or control (NFP only) condition. The final sample consisted of 238 women completing baseline assessments; retention was 81% at 2-year follow-up., Results: Analyses indicated that there were no main effects: the intervention affected participants differently depending on their baseline experience with IPV. For physical violence victimization, an interaction between baseline victimization and treatment was found; the intervention reduced victimization at 1 year (and approached significance at 2 years), but only among women who had not experienced past-year physical victimization at baseline. For sexual violence victimization, another interaction emerged; women in the intervention group were more likely to report sexual violence victimization at 2-year follow-up, but only among participants who had reported sexual victimization at baseline. The only effect on IPV perpetration was psychological perpetration at 2-year follow-up; again, the treatment effect was moderated by baseline perpetration. The intervention reduced psychological perpetration for participants who were nonperpetrators at baseline, but had no effect on those reporting perpetration., Conclusions: Overall, findings suggest that the intervention was effective in reducing some forms of violence among those not experiencing IPV at baseline, but was ineffective or potentially harmful for those already experiencing IPV.

The lack of rigorous evaluations of intimate partner violence (IPV) programs has severely limited our knowledge about what works. However, IPV programs can be rigorously evaluated through randomized controlled trials (RCTs) conducted ethically and safely. This article provides an example of how a RCT to test an IPV preventive intervention-the Enhanced Nurse Family Partnership Study (ENFPS)-was successfully implemented by a partnership of researchers and practitioners. The article concludes with some recommendations, arrived at by the researchers and practitioners on the ENFPS team, for achieving a successful collaboration thought to be essential in executing a field experiment., (© The Author(s) 2011.)

This research provides information on dually arrested female defendants in domestic violence cases. The data comes from all heterosexual domestic violence cases resulting in a dual arrest from one large mid-South city during a 28-month period. Information on matched pairs of dually arrested male and female defendants (N = 317) came from multiple sources, including official criminal justice records (arrest reports and local criminal histories) as well as victim/offender interviews with both the arrestee and his/her partner. Comparisons were made between males and females in terms of their demographics, criminal histories, prior history of domestic violence (as both victim and offender), and behavior during the instant offense. Analyses revealed that these couples had ample contact, whether as victim or offender, with the criminal justice system. While there were no significant differences in partners' reports of minor and severe physical abuse, criminal justice date indicated that male arrestees demonstrated a significantly higher overall level of severity of violence than their female counterparts. Additionally, male arrestees had a more serious history of intimate partner and extrafamilial violence as well as other indicators of an antisocial lifestyle in comparison to female arrestees. To the extent that females in our cohort demonstrated less overall criminality and engaged in less severe domestic aggression, the idea of equivalency of violence between male and female arrestees must remain questionable.
