Objective: The purpose of this study is to (a) evaluate a 16-week batterer intervention program by investigating changes in psychological variables related to abuse between pretreatment and posttreatment assessments in a sample of women involuntarily placed in treatment and (b) to investigate the differential effectiveness of this same batterer intervention program for African American and White batterers. Method: The study employed a secondary analysis of 59 treatment completers. Results: The findings of this study suggest that the court-ordered batterers constituting this sample demonstrate significant changes, in the desired direction, on psychological variables related to domestic violence, as a result of participation in a court-mandated treatment program, and there was no significant difference in terms of magnitude of change on these same psychological variables between African American and White batterers, indicating that the treatment program was reaching both groups equally well. Conclusion: Implications of the findings for social workers were explored and discussed. (Contains 3 tables.)
