This study revealed that a large proportion of suicidal soldiers met diagnostic criteria for BPD, despite the low prevalence of personality disorders in military medical records of soldiers who attempt or die by suicide.

• 27.7% of suicidal soldiers in a sample size of 137 met full diagnostic criteria for BPD
• Active-duty soldiers with BPD were less likely to be married, were of lower rank, and had fewer deployments
• Higher number of BPD symptoms were correlated with higher numbers of nonsuicidal self-injury but not with amount of suicide attempts.
• Efforts to avoid abandonment were higher among soldiers with BPD
• The total proportion of participants who met each of the BPD criteria indicate that soldiers without BPD reported nontrivial experiences of BPD criteria and 1/3 met the impulsivity and/or paranoid ideation or severe dissociation criteria
