Objective: The purpose of the present study was to evaluate pretreatment differences between treatment completers and dropouts among a large sample of women ordered into a 26-week batterer intervention program (BIP). Method: The study employed a nonequivalent, control-group design (comparing program completers to dropouts) in a secondary analysis of 485 women mandated into a BIP. Results: Analysis indicated that (a) there are specific psychosocial risk factors associated with an increased probability of program attrition in both women and men batterers; (b) these risk factors increase attrition rates for women in treatment programs; and (c) the level of supervision dictated by the referral source is correlated to program completion for women in this study. Conclusion: These findings reveal characteristics of women batterers as they relate to the likelihood of completing treatment programs. (Contains 2 tables.)
