Objective: The purpose of the present study was to investigate the impact of gender and other variables commonly associated with intimate partner abuse perpetration on program completion and pretreatment abusiveness profiles among a sample of men and women ordered into a 52-week batterer intervention program (BIP). Method: The study employed a posttest only design with nonequivalent groups (comparing program completers to dropouts and men to women) in an analysis of 175 clients mandated into a BIP. Results: Analysis indicated that there were no significant differences between men and women in terms of program completion and that women were significantly more likely than men to report engaging in severe physical abuse perpetration, and a logistic regression analysis indicated that dropouts were 6 times more likely to have initiated physical abuse compared to completers. Conclusion: These findings reveal characteristics of BIP program participants as they relate to self-reported abusiveness and provide preliminary evidence suggesting that both BIP pretreatment profiles and treatment completion rates of men and women are similar, with implications for policy and treatment.
