영문 초록

Objectives：This study aims to test the validity of the Korean version of Mood Disorder Questionnaire (K-MDQ), a screening instrument for bipolar disorder. Methods：A total of 238 subjects (126 DSM-IV bipolar outpatients and 112 controls without psychiatric history) completed the K-MDQ. Results：The Cronbach’s alpha, used to measure the internal consistency of the scale, was high (0.88). Principal component analysis with varimax rotation revealed three factors, which explained 59.5% of the variance. Individual item correlations with the total score were all statistically significant (p<0.001). The mean total score of the K-MDQ was 8.48 in bipolar disorder and 4.51 in non-clinical participants. A total K-MDQ score of 7 or more excluding further two questions was chosen as the optimal cutoff, as it provided good sensitivity (0.75) and specificity (0.69). Conclusion：The results of this study showed adequate validity of the K-MDQ, suggesting that this instrument is useful for screening of bipolar disorder
