In addition to suicidal behaviors, men with borderline personality disorder (BPD) often display antisocial behavior that could impair contacts with mental health services. While research has established effective treatments for women with BPD, this is not yet the case for men. The authors evaluated 12 months of dialectical behavior therapy (DBT) for 30 men with BPD and antisocial behavior, using a within-group design with repeated measurements. The authors found moderate to strong, statistically significant pre-to posttreatment reductions of several dysfunctional behaviors, including self-harm, verbal and physical aggression, and criminal offending (rate ratios 0.17-0.39). Symptoms of BPD and depression were also substantially decreased. The dropout rate was 30%, and completing participants reported high satisfaction with treatment and maintained their improvements at 1-year follow-up. The authors conclude that DBT could be an effective treatment alternative for men with BPD and antisocial behavior, and it merits future studies with more rigorous design.
