ABSTRACT

La escala para Depresión Geriátrica, de 5 y 15 ítems (GDS-5 y GDS-15), cuantifica síntomas depresivos en adultos mayores. Sin embargo, no se ha explorado el comportamiento psicométrico de la versión de cinco ítems en población colombiana. El presente trabajo se propuso estudiar la consistencia interna, la confiabilidad de constructo y la estructura factorial de la GDS-15 y de la GDS-5. Participaron en la investigación 105 adultos mayores colombianos y se calcularon: consistencia interna, confiabilidad de constructo y estructura factorial. La GDS-15 presentó consistencia interna de 0.78, confiabilidad de constructo de 0.87 y estructura bidimensional. La GDS -5 mostró consistencia interna de 0.73, confiabilidad de constructo de 0.83 y estructura unidimensional. En conclusión la GDS-5 muestra mejor comportamiento psicométrico que la GDS-15. Sin embargo, se recomienda desarrollar el diseño de una escala más confiable en esta población.


The Geriatric Depression Scale (GDS), 5 and 15-items version, are useful for identify depressive symptoms among elder people. However, psychometric properties of a version of five items has not explored among colombian elders. The aim of this paper was to study the internal consistency, the factor structure and the construct reliability of the GDS-15 and GDS-5. A total of 105 colombian people over 65 year-old participated in this investigation. The internal consistency, the construct reliability and the exploratory factor analysis were computed. The GDS-15 showed internal consistency of 0.78, the construct reliability of 0.87 and two-dimensional structure. The GDS-5 exhibited internal consistency of 0.73, construct reliability of 0.83 and one-dimensional structure. In conclusion the GDS-5 shows better psychometric properties than the GDS-15. However, it is recommended to develop the design a new and more reliability scale.
