Randomized Clinical Trial of a Brief Alcohol Intervention as an Adjunct to Batterer Intervention for Women Arrested for Domestic Violence.

Despite a rise in women being arrested for domestic violence and court-ordered to batterer intervention, batterer interventions remain limited in their ability to address women's treatment needs. Alcohol use is an important intervention target: one-third of women in batterer interventions have an alcohol-related diagnosis, half engage in at-risk drinking, and alcohol use contributes to intimate partner violence (IPV) and batterer intervention dropout. Research has not evaluated whether adding an alcohol intervention to batterer intervention improves women's alcohol use and IPV outcomes. We randomized 209 women (79.9% white) in Rhode Island to receive the state-mandated batterer intervention program alone or the batterer intervention program plus a brief alcohol intervention. Alcohol use (percentage of days abstinent from alcohol [PDAA], number of drinks per drinking day [DPDD], percentage of heavy drinking days [PHDD], percentage of days abstinent from alcohol and drugs [PDAAD]), and IPV perpetration and victimization frequency (psychological, physical, and sexual IPV, injury) data were collected at baseline and 3-, 6-, and 12-month follow-up. Multilevel modeling revealed that, relative to the batterer intervention alone, women who received the brief alcohol intervention reported a higher PDAA and PDAAD, fewer DPDD, and a lower PHDD across all follow-up assessments. Women who received the brief alcohol intervention perpetrated less physical IPV and experienced less injury than did women who only received the batterer intervention. For physical IPV, these differences became more pronounced over time. No other group differences or group x time interactions emerged. Adding an alcohol intervention may improve batterer intervention outcomes for women arrested for domestic violence.
