CAMPO-ARIAS, Adalberto et al. Psychometric Properties of the CES-D Scale Among Colombian Adults from the General Population. rev.colomb.psiquiatr. [online]. 2007, vol.36, n.4, pp.664-674. ISSN 0034-7450.

Background: Around the world, the Center for Epidemiologic Studies Depression Scale (CES-D) is the most popular instrument to identify depressive disorders in the community. However, this scale has not been validated in Colombia. Objective: To validate the CES-D in the general population of Bucaramanga, Colombia. Method: A random sample of adults (N=266) was evaluated. After the participants completed the CES-D, a psychiatrist interviewed them to detect a current major depressive episode (MDE) using the Structured Clinical Interview for a DSM-IV diagnosis. Results: The psychiatric clinical interview identifi ed 44 (16.5%) people with MDE. The ROC suggested 20 as the best cut-off point. With this cut-off point, 102 (38.3%) people reported clinically meaningful depressive symptoms, with an observed concordance of 0.77 (95%CI 0.71-0.82); sensitivity for a MDE, 0.96 (95%CI 0.83-0.99); specifi city, 0.73 (95%CI 0.67-0.79); positive predictive value, 0.41 (95%CI 0.32-0.51); negative predictive value, 0.99 (95%CI 0.95-1.0); positive likelihood ratio, 3.53; negative likelihood ratio, 0.06; and Cohen’s kappa test, 0.45 (95%CI 0.35-0.55). The Cronbach’s alpha was 0.87, and four factors explained 50.3% of the variance. Conclusions: The CES-D with a cut-off point of 20 may be a useful tool for MDE screening in Colombian adults.
