Treatment outcomes of Veteran men in a comprehensive dialectical behavior therapy program: Characterizing sex differences in symptom trajectories

Dialectical Behavior Therapy (DBT) is one of the primary psychosocial treatments for reducing suicidal behaviors and improving psychosocial outcomes among patients with borderline personality disorder (BPD) and has been shown to reduce BPD symptoms when delivered in a Veteran Affairs medical center setting. Despite evidence of similar rates of BPD in both men and women, the vast majority of treatment outcome research in BPD has focused on women. We sought to characterize sex differences in symptom trajectories among Veterans participating in a comprehensive DBT program. We found that Veteran men and women who entered the DBT program were diagnostically and demographically similar. Participants exhibited reductions in BPD symptoms and improvements in emotion regulation over the course of treatment. Moreover, Veteran men reported BPD symptom reductions that were not statistically inferior to those of Veteran women and exhibited a sharper reduction in these symptoms. This research provides support for the use of DBT as a psychosocial treatment for Veteran men with BPD symptoms.
