Results from the study indicated that the levels of intimate partner violence were much higher among police detainees (49 percent) than what was found from general population surveys. More than two-thirds of the detainees who were involved in partner violence reported being both a victim and a perpetrator in the past 12 months. Factors found to be significant risk markers for detainees’ involvement in partner violence include prior arrest, drug and alcohol dependency, having dependent children, and experiencing physical abuse as a child. Once these risk factors were controlled, gender was not found to be a significant risk marker. Policy implications indicate the need for early intervention with at-risk families and where drug and alcohol dependency issues are emerging. Few studies exist on intimate partner violence and the at-risk arrestee population. This paper examines the issue of intimate partner violence among a sample of 1,597 adult men and women who are detained by police in a police station or watch house involved in the DUMA program.
