Abstract

BackgroundWe 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.MethodsIn 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.ResultsThe 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.LimitationsThis study includes a small number of bipolar I patients. The findings might not be generalized to patients outside of this patient population.ConclusionsThe 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.
