Abstract:
OBJECTIVES: This study aimed to assess the prevalence of bipolar spectrum disorders among Korean high school students (individuals in late adolescence) using the Korean version of the Mood Disorder Questionnaire (K-MDQ). METHODS: Two thousand male and female participants were proportionately selected from among high school students nationwide. From November 2007 through February 2008, we conducted an epidemiological survey of, and administered the K-MDQ to, these participants, assessed their psychometric properties, and compared characteristics between K-MDQ-positive and K-MDQ-negative participants. RESULTS: The K-MDQ's internal consistency (Cronbach's alpha) was 0.74. The item-total score correlations ranged from 0.35 to 0.57, and all were statistically significant (p<.001). Factor analysis with varimax rotation revealed 3 factors that explained 42.6% of total variance. We found the cutoff endorsement of the K-MDQ score (7 or more in criteria 1) in 1207 students (60.4%) and found 104 (5.2%) subjects were K-MDQ-positive, meeting all 3 K-MDQ criteria. The mean K-MDQ total score was 7.2+/-2.9 and total scores of K-MDQ-positives and K-MDQ-negatives were 9.9+/-1.7 and 7.0+/-2.9, respectively. K-MDQ-positives and K-MDQ-negatives showed no differences in the sociodemographic variables we assessed. Endorsement of items in total subject ranged from 15.7% to 77.7%. All items except item 8 (more energy) differed significantly in endorsement between K-MDQ-positives and K-MDQ-negatives. Items accounting for over 30% of the endorsement differences between K-MDQ-positives and K-MDQ-negatives were"feel so good," "so irritable," and"excessive, foolish, risky behavior." CONCLUSION: The K-MDQ was a relatively valid screening tool for Korean high school students. Per the result of the K-MDQ survey, suspected lifetime prevalence of bipolar spectrum disorders for those in late adolescence (high school students) seems to be 5.2%, suggesting that systemic screening for bipolar spectrum disorder should be required for this age group.
