Objectives : This study was performed to standardize the Korean version of Beck Depression Inventory Ⅱ(BDI-Ⅱ) , self-rating scale to assess severity of depressive symptoms. Also, this study was performed to determine psychometric properties and clinical usefulness of the BDI-Ⅱ.

Results : Internal consistency using Cronbach α was 0.834 in depressive patient group and 0.880 in normal control group. In addition, 8DI-Ⅱ showed a very good criterion validity with very strong correlations with BDI, SCL-90-R, MMPI and HAMD. The area under the ROC curve was 0.992. With cut-off point of 22, the korean version BDI-Ⅱ had a sensitivity .935, specificity .981. And discriminant ability was 95.4%
