Background: The purpose of this study is to develop the Korean dysfunctional depression submodule scales, which are composed of hwa-byung, mood dysregulation, female depression, anxiety, spouse conflict and suicidal risk.
Methods: To achieve this purpose, we developed preliminary items of six submodules through the theoretical approach and experiential approach. Then we collected data from professionals and para-professionals in mental health area (n=407) and 275 data were used to analyzed. Correlation with criterion, item information function, item-total correlation, and explorative factor analysis are performed using Mplus 7.4 and SPSS 21.0.
Results: 6 submodules of the Korean dysfunctional depression are composed of 8 items for Hwa-byung, 7 items for mood dysregulation, 7 items for female depression, 7 items for anxiety, 7 items for spouse-conflict and 9 items for suicidal risk. Reliability of submodules are .84∼.93.
Conclusions: These submodules of the Korean dysfunctional depression scale are verified to have high reliability and expected to be useful to assess the specific and various features of the dysfunctional depression.
