Reliability and validity of the Chinese Version of the Mood Disorder Questionnaire.
The purpose of this study was to examine the reliability, validity, sensitivity, and specificity of the Chinese Version of the Mood Disorder Questionnaire (MDQ-C). A total of 170 patients were administered the Mini International Neuropsychological Interview and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision as criterion standard by on-site psychiatrists. The Cronbach's alpha, test-retest reliability, and the content validity index of the MDQ-C were .83, .76, and .80, respectively. Factor analysis revealed that two factors, elevated mood overactivity and irritable behavior, explained 40.89% of the variance. On the basis of the sensitivity and specificity results, the optimal cutoff point was 6. The MDQ-C is an effective short and comprehensive tool with robust psychometric properties for diagnosis of bipolar disorders, specifically for patients with bipolar I.
