Differential Item Functioning of the Center for Epidemiologic Studies Depression Scale Among Chinese Adolescents.

This study examined differential item functioning (DIF) in the Center for Epidemiologic Studies Depression Scale (CES-D) between Chinese and White adolescents (aged 13 to 17 years) living in Canada. A series of ordinal logistic regressions were used to test for uniform and non-uniform DIF on items in the CES-D. The DIF analyses identified non-uniform DIF for Item 7 ("I felt that everything I did was an effort"). Controlling for gender and strength of ethnic identity in the DIF analyses did not alter the DIF results. The results of this study suggest that CES-D Item 7 does not appear to discriminate at higher levels of depression in Chinese adolescents. The results of this study hold notable implications for the use of the CES-D given that Chinese adolescents demonstrated a systematic difference in expression/experience of depression.
