Abstract

Objectives : We examined the reliability and validity of the Korean version of the Depression and Somatic Symptom Scale (DSSS) in Korean patients with depressive symptoms. Methods : Participants were 55 outpatients diagnosed with major depressive disorder, a depressive episode of bipolar I disorder, somatoform disorder, panic disorder, generalized anxiety disorder, or post-traumatic stress disorder according to the DSM-IV criteria. We assessed them using the Korean versions of the DSSS, Hamilton Depression Rating Scale (HDRS), and Quick Inventory of Depressive Symptomatology Self Report (QIDS-SR). Results : The Korean version DSSS had a Cronbach's alpha of 0.90. Moreover, each item's correlation with the total score was statistically significant (r=0.24-0.71, p<0.01). The test-retest correlation coefficient (r=0.83, p<0.01) was relatively high, and the DSSS correlations with the HDRS and QIDS-SR were 0.77 and 0.74, respectively. Conclusion : These results demonstrate that the Korean version of the DSSS could be a reliable and valid tool for screening and assessing depressive patients. The Korean version of the DSSS will be a useful tool for screening both depressive and somatic symptoms in Korea.
