Abstract

BACKGROUND: We developed a self-reported questionnaire, the Manic Episode Screening Questionnaire (MES), based on the eight diagnostic criteria items of DSM-IV-TR (hypo)manic episodes. This study was designed to determine the optimal screening methods to identify bipolar disorders among mood disorder patients of a psychiatric specialty clinic. METHODS: In 95 mood disorder patients, we assessed the operational characteristics of the MES as a screening and diagnostic instrument using a DSM-IV-TR diagnosis by a trained psychiatrist as a reference standard. The reference criteria were bipolar disorders. MES was used with two methods: the diagnostic algorithm and the one-question method (question #1 only). The diagnostic algorithm was regarded as fulfilled if the answers to question #1 and three or more of questions #2 to #8 were "yes", corresponding to the DSM-IV-TR (hypo)manic episode criteria. In different subjects, the test-retest reliability of the MES was examined. RESULTS: The two methods of the MES showed high specificity (0.93-0.94), high positive predictive value (0.81-0.83) and high negative predictive value (0.88-0.90), but the sensitivity scored lower (0.68-0.75). The test-retest reliability was moderate: 0.75 for the diagnostic algorithm and 0.68 for the one-question method. LIMITATIONS: This study includes a small number of bipolar I patients. The findings might not be generalized to patients outside of this patient population. CONCLUSIONS: The MES is useful for the screening and diagnosis of bipolar disorders among mood disorder patients in psychiatric specialty clinics. The one-question method of the MES is more convenient to use than prior questionnaires and is here recommended.
