Abstract
Background The aims of this study were to examine the reliability and the validity of the Korean version of the Patient Health Questionnaire-9
(PHQ-9).
Methods The PHQ-9, Patient Health Questionnaire-2 (PHQ-2), and Center for Epidemiologic Studies Depression Scale (CES-D) were
administered to 58 normal subjects and 109 patients (depression 61, anxiety 48).
Results The values of Cronbach's alpha and test-retest correlation coefficient were .936 and .553 (P<.001), respectively. The depressed
group yielded higher scores on the PHQ-9 than normal and anxiety groups. The PHQ-9 correlated strongly with PHQ-2 (r=.759)
and CES-D (r=.716). The discriminant analysis showed that the hit ratio of PHQ-9 was 90.8%. Sensitivity and specificity were
85% and 52%, respectively.
Conclusions The PHQ-9 showed to be a reliable and valid screening tool for depression.
연구배경 : 본 연구는 한국판 PHQ-9의 표준화를 위한 예비연구로 이루어졌다. 방 법 : 58명의 정상군과, 109명의 환자군(우울증 61, 불안장애 48)에게 PHQ-9, PHQ-2, CES-D를 함께 실시하였다. 결 과 : Cronbach alpha값은 .936으로 상당히 높았으며, 검사-재검사 신뢰도 계수는 .553으로 양호한 상관관계를 보였다 (r=.553, P<.001). 우울증 환자군은 불안장애 환자군과 정상군에 비해 PHQ-9의 평균 점수가 높게 나타났다. 그리고 PHQ-9점수는 PHQ-2 (r=.759), CES-D (r=.716) 와 높은 상관관계를 보였다. 끝으로 한국판 PHQ-9의 절단점을 9.5이상으로 하였을때 민감도는 85%, 특이도는 52%를 보였다. 결 론 :한국판 PHQ-9는 우울증 선별검사도구로서 신뢰롭고 타당할 수 있음이 나타났다.
