The psychometric properties of the center for epidemiological studies-depression scale (ces-d) when used with adults with physical disabilities

Abstract

Psychometric properties of the Center for Epidemiological Studies Depression Scale (CES-D) were examined in a sample of 790 adults with physical disabilities and compared to the responses obtained from non-disabled samples (Craig and Van Natta, 1976; Radloff, 1977). Findings suggested the CES-D is a valid measure of depressive symptoms among adults with physical disabilities. Scores on the CES-D scale were not elevated by somatic issues related to physical disability as evidenced by the lack of statistically significant differences in the persistence percentages reported by adults with physical disabilities and non-disabled adults for four of the seven items composing the somatic dimension of the CES-D. Moreover, the factor structure obtained via principal components analysis was highly similar to that obtained with non-disabled adults. Likewise, the Cronbach alpha value for the total score was within acceptable ranges and scores on the CES-D scale were moderately correlated with scores on a number of related but putatively distinct constructs.
