Reliability and factor structure of the Brazilian version of the Center for Epidemiologic Studies-Depression.

The Center for Epidemiologic Studies-Depression scale is a screening test designed by the National Institute of Mental Health (USA) to screen for 'depressed' individuals in the community. It has been widely used in different settings and cultures displaying variable psychometric properties. The present article describes coefficients of internal consistency and factor analysis of the CES-Depression version adapted for use in Brazil. In a sample of 523 college students internal consistency measured by Cronbach alpha was .85. Structure analysis evidenced that two questions were poorly correlated with the remaining questions. Factor analysis resulted in a four-dimension solution accounting for 53.8% of the total item variance. The scale is adequate for use in this different cultural setting.
