Abstract

Objective : The reliability and validity of the Korean version of the Patient Health Questionnaire-9 (PHQ- 9) was examined in Korean patients with depressive symptoms. Methods : Eighty six outpatients diagnosed as major depressive disorder or depressive episode of bipolar I disorder according to the DSM-IV criteria were assessed with the PHQ-9, Hamilton Depression Rating Scale (HDRS), the Quick Inventory of Depressive Symptomatology Self Report (QIDS-SR), and the Center for Epidemiologic Studies Depression Scale (CES-D). Results : The Cronbach's alpha coefficient from the PHQ-9 was 0.81. And the correlations of each item with the total score were statistically significant (r=0.28-0.70, p<0.01). The test-retest correlation coefficient (r=0.89, p<0.01) was relatively high and correlations of the PHQ-9 with the HDRS, QIDS-SR and CES-D were 0.70, 0.81, and 0.81 respectively. Conclusion : These results demonstrated that the Korean version of PHQ-9 could be a reliable and valid tool for the screening and assessment of depressive patients. The Korean version of PHQ-9 will be a useful tool for screening depressive symptoms in Korea.
