Borderline personality disorder and self-directed violence in a sample of suicidal army soldiers.

Abstract

There has been a sharp increase in the military suicide rates in 2004. While, borderline personality disorder (BPD) has a stronger association with suicide attempts than any other mental health disorder, there is limited evidence concerning the prevalence and scope of BPD symptoms among military personnel. This secondary data analysis compared active duty suicidal soldiers to characterize the presence-absence of BPD diagnostic criteria and lifetime history of self-directed violence in a suicidal military sample. The current study examined data of 137 active Service Members with significant suicidal ideation. Approximately one-quarter of the soldiers in this sample met full diagnostic criteria for BPD. The presence of BPD criteria was generally consistent among participants with BPD who reported past self-directed violence relative to those who did not. The number of BPD criteria was a significant predictor of the odds of reporting any nonsuicidal self-injury (NSSI) as well as the amount of NSSI, but was not associated with suicide attempt. This study demonstrated that a nontrivial proportion of suicidal soldiers meet criteria for this condition, which is strongly associated with self-directed violence. It is important to rigorously assess for the presence-absence of BPD criteria among suicidal military personnel and cultivate prevention strategies and treatment options for BPD.
