Abstract

Background

The Center for Epidemiologic Studies Depression Scale (CES-D) is used at workplaces to screen depressive disorders. The aim of this study was to examine the validity of the CES-D for depression in a workplace.

Methods

The CES-D was administered to 2,219 workers (84.2% men; age 21–68 years) at a manufacturing company in Japan. Concomitantly all workers had an interview with the Mini International Neuropsychiatric Interview (MINI) as a gold standard for diagnosing major depressive disorder (MDD). The validity was evaluated by a receiver operating characteristic (ROC) curve.

Results

The area under the ROC curve of the CES-D was 0.96 [95% Confidence Interval (CI): 0.94–0.99]. The optimal cut-off score of MDD was 19 for screening.

Conclusions

The validity of CES-D is confirmed and it is a valid instrument for detecting MDD in working populations in Japan. Am. J. Ind. Med. 50:8–12, 2007. © 2006 Wiley-Liss, Inc.
