RESUMO
OBJECTIVE: The aim of this study was to examine the validity of the Korean version of the Hypomania Checklist-32, second revision (HCL-32-R2) in mood disorder patients. METHODS: A total of 454 patients who diagnosed as mood disorder according to Structured Clinical Interview for DSM-IV Axis I Disorders, clinician version (SCID-CV) (bipolar disorder [BD] I, n=190; BD-II, n=72; and major depressive disorder [MDD], n=192) completed the Korean module of the HCL-32-R2 (KHCL-32-R2). RESULTS: The KHCL-32-R2 showed a three-factorial structure (eigenvalue ï¼2) that accounted for 43.26% of the total variance. Factor 1 was labeled "active/elated" and included 16 items; factor 2, "irritable/distractible" and included 9 items; and factor 3 was labeled "risk-taking/indulging" and included 9 items. A score of 16 or more on the KHCL-32-R2 total scale score distinguished between BD and MDD, which yielded a sensitivity of 70% and a specificity of 70%. MDD and BD-II also could be differentiated at a cut-off of 15 with maximized sensitivity (0.67) and specificity (0.66). Cronbach's alpha of KHCL-32-R2 and its subsets (factors 1, 2, and 3) were 0.91, 0.89, 0.81 and 0.79, respectively. Correlations between KHCL-32-R2 and Montgomery- Asberg Depression Rating Scale, Young Mania Rating Scale and Korean version of Mood Disorder Questionnaire were -0.66 (p=0.41), -0.14 (p=0.9), and 0.61 (pï¼0.001), respectively. CONCLUSION: The KHCL-32-R2 may be a useful tool in distinguishing between bipolar and depressive patients in clinical settings.
RESUMO
INTRODUCTION: The purpose of this study was to assess the usefulness of the Korean version of the Mood Disorder Questionnaire (K-MDQ) as a screening tool for the identification of bipolar spectrum disorder (BSD) among Korean college students. METHODS: The sample of 1,020 college students was stratified to reflect geographical differences among the students. The K-MDQ and an epidemiological survey were administered between November 2006 and February 2007. To validate the K-MDQ as a screening tool for BSD, the Korean version of the Bipolar Spectrum Diagnostic Scale (K-BSDS) and the Structured Clinical Interview for DSM-IV (SCID) were also administered. RESULTS: The rates satisfying MDQ criterion 1, and all three MDQ criteria, were 55.5% and 2.3%, respectively. According to the K-BSDS, 59.9% of the sample met the criteria for BSD using a threshold of 10, while no statistical differences were observed among subgroups. When we examined the diagnostic agreement between K-MDQ and K-BSDS, 79.5% of students who met MDQ criterion 1 were also positive on the BSDS. Sixteen (21.6%) of the 74 students who participated in the SCID interview were diagnosed with BSD. DISCUSSION: Although the K-MDQ is a useful tool to assess BSD among inpatients and outpatients, it does not appear useful as a screening tool to detect BSD among college students.

BACKGROUND: The purpose of this study was to assess the prevalence of bipolar spectrum disorder (BSD) in the general Korean population. METHODS: A sample of college students (n = 1026) was stratified to reflect geographical differences accurately in Korean college students. The Korean version of the Mood Disorder Questionnaire (K-MDQ) was administered and an epidemiological survey carried out between November 2006 and February 2007. BSD was defined as a score of at least seven K-MDQ symptoms that co-occurred and resulted in minimal or more functional impairment. RESULTS: The prevalence of BSD was 18.6% (95% confidence interval [CI] 16.2-21.0) in total, being 19.8% (95% CI 16.3-23.2) in men and 17.5% (95% CI 14.2-20.8) in women. The prevalence of BSD was more common in rural dwellers than in urban dwellers (P = 0.008, chi-square test). Univariate and multivariate regression models showed that rural residence was a significant factor associated with BSD. There were significant relationships between BSD and gender, age, and socioeconomic status. CONCLUSION: The prevalence of BSD found in the present study is higher than that reported by other epidemiological studies in Korea and in international studies.
