Abstract
OBJECTIVE: To establish reliability and validity of the abbreviated (10-item) Center for Epidemiologic Studies Depression Scale (CESD-10) among individuals post stroke. METHOD: The psychometric properties of the CESD-10 were evaluated in 1219 adults with stroke admitted to an eligible inpatient rehabilitation facilities (n = 11) across 9 different states post stroke during 2005 to 2006. This study was a secondary data analysis of the existing publicly available clinical trial dataset, Stroke Recovery in Underserved Populations study. Reliability, validity, factory structure and item-level psychometrics of the CESD-10 were examined. In addition, the predictive accuracy of the CESD-10 was compared against the CESD-20 (criterion). RESULTS: The CESD-10 was highly correlated with the CESD-20 (r = 0.97). The CESD-10 had good internal reliability (Cronbach's α = 0.86). The CESD-20 and CESD-10 had similar accuracy in classifying individuals as depressed (Kappa = 0.85). CONCLUSION: The 10-item CESD is a valid measure of depression for individuals post stroke.
