Screening for Borderline Personality Disorder in Psychiatric Outpatients With Major Depressive Disorder and Bipolar Disorder

摘要

Objective: Borderline personality disorder (BPD) is a serious illness that is frequently underdiagnosed. A previous psychometric analysis of the 9 BPD criteria in DSM-IV/DSM-5 found that the affective instability criterion functioned well as a screen for the disorder. A limitation of that initial study was that the performance of the BPD criteria was examined in a diagnostically heterogeneous sample, including those with a low likelihood of having BPD. The present study from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project examined the operating characteristics of the BPD criteria in patients with major depressive disorder (MDD) and bipolar disorder.
