Reliability and validity data for a Chinese translation of the Center for Epidemiological Studies-Depression.

A translated version of the CES-Depression scale attained a reliability coefficient alpha of 0.92 in a group of 30 adult Chinese persons with noninsulin-dependent diabetes mellitus. Fifteen percent of the sample scored 16 or above, which has been noted as indicative of depression in U.S. samples. The validity of the instrument was assessed through an in-depth content analysis and through convergent validity analyses. Comparison of depression scores of this sample with those from English-speaking Occidentals shows that diabetes disease-related factors may be an important influence on depression.
