主要憂鬱症환자 예비평가에서 the Center for Epidemiologic Studies Depression Scale(CES-D)진단적 타당성 연구 = Diagnostic Validity of the CES-D(Korean Version) in the Assessment of DSM-Ⅲ-R Major Depression

다국어 초록 (Multilingual Abstract)

Through four times of preliminary trials, the authors translated the Center for Epidemiologic Studies Depression Scale(CES-D), a self-reporting depression scale, into Korean, paying particular attention to the culturally different mode of expression of depressive feelings and thoughts.
The final version of the CES-D was administered to 164 psychiatric patients (30 schizophrenic, 31 alcohol dependence, 30 anxiety disorder, 46 major depression, 27 remitted depression), and 540 non-random selected general population.
Reliability and validity test, optimal cut-off point estimation, and ROC curve analysis were done to investigate the diagnostic validity of this depression screening instrument in assessing clinical depression (DSM-III-R major depression).
Internal consistency-reliability and concurrent validity associated with other depression measure scales(HRDS. DSI, BDI) were excellent Content validity and discriminant validity which differentiate DSM-III-R major depression patients from other psychiatric patients were also good.
The authors suggested the score '25' as the optimal cut-off point in clinical setting, and the score '21' in the community setting for its use as a primary screening test for further test to identify DSM-III-R major depression. This relatively high cut-off point was reviewed in the viewpoint of culturally determined style of response for the depression questionnaire in Korea.
ROC curve analysis revealed wide AUC of this instrument which indicates its high diagnostic validity in assessing DSM-III-R major depression. Observer rating scales such as HRSD and DSI were a bit superior to self reporting scales, and the CES-D and BDI showed almost equal diagnostic validity in assessing DSM-III-R major depression.
