Within a sample of depressed patients, the Mood Disorder Questionnaire (MDQ) triad is a better screener for bipolar disorder (BD) than the full MDQ, particularly if a positive triad screen is indicated by the presence of any 2 items, according to a recent study. The triad is particularly good for differentiating between BD and borderline personality disorder (BPD), whereas the full MDQ does a poorer job of differential diagnosis. Patients presenting for treatment were assessed with the Structured Clinical Interview for DSM-IV (SCID) and the BPD module of the Structured Interview for DSM-IV Personality (SIDP-IV). The present report is based on 476 depressed patients who had a principal diagnosis of major depressive disorder (MDD) or BD and who completed the MDQ. Researchers found:
- 57 patients were diagnosed with BD and 54 patients were diagnosed with BPD.
- Both the triad and full MDQ significantly predicted BD diagnosis, but the triad had optimal operating characteristics, particularly at a cut-off of 2.
