GEMPP, René  y  THIEME, Claudio. Effect of different scoring methods on the reliability, validity, and cut points of the Center for Epidemiologic Studies Depression Scale (CES-D). Ter Psicol [online]. 2010, vol.28, n.1, pp.5-12. ISSN 0718-4808.  http://dx.doi.org/10.4067/S0718-48082010000100001.

This study compare the effect of four scoring methods for the Center for Epidemiologic Studies Depression Scale (CES-D) on score reliability, concurrent validity, cut points, sensibility, specificity and classifica-tion reliability of the scale. The CES-D was scored using the conventional "ordinal" method, two binary methods ("presence" and "persistence" of symptoms) and a new "weekly" scoring system. On the basis of both psychometric analysis and receiver operating characteristic (ROC) analysis, performed on normative (n=1143) and clinical (n=44) samples, it was found that the "ordinal" and "weekly" methods performed best in detecting depression. On the other hand, the "persistence" of symptoms method resulted in worse performance. Overall, the results indícate that the scoring method has an effect on the reliability and validity of the CES-D.

Palabras clave : CES-D; scoring method; reliability; concurrent validity; ROC curves.
