Resumen: Esta investigación tuvo como objetivo validar el Cuestionario Tridimensional para la Depresión (Jiménez y Mi guelTobal 2003) en población venezolana con enfermedades crónicas. Se evaluó la estructura factorial a través de un análisis de componentes principales, así como su consistencia interna y sus asociaciones con el inventario de Ansiedad Rasgo de Spiel berg en una muestra de 202 pacientes con diabetes mellitus, hipertensión y enfermedades anorectales. Se obtuvo una fiabilidad aceptable (α = .857)y una estructura de tres componentes (motor, cognitivo y fisiológico). La correlación con la dimensión de ansiedad rasgo fue satisfactoria (r = .706), lo que sugiere que el cuestionario posee adecuada validez convergente. Posteriormen te, se realizó un análisis factorial confirmatorio con una muestra diferente de 322 pacientes, cuyos resultados demuestran un mal ajuste de los datos. Se recomienda verificar los resultados, analizando las propiedades psicométricas del cuestionario con otras muestras de personas con enfermedades crónicas.Palabras clave: Depresión; Cuestionario Tridimensional para la Depresión; evaluación psicológica; enfermedades crónicas. Tridimensional Depression Questionnaire: Validation in a Venezuelan population with chronic diseasesAbstract: The aim of the present study was to validate the Tridimensional Depression Questionnaire (Jiménez y MiguelTobal, 2003) in a Venezuelan population with chronic diseases. The factorial structure was analyzed using a principal component analysis (PCA), as well as the internal consistency and correlations with Spielberg's StateTrait Anxiety Inventory, in a sample of 202 patients with diabetes mellitus, hypertension, and anorectal diseases. An adequate reliability (α= .857) and a three factor structure (motor, cognitive and physiological) were obtained. The correlation with trait anxiety was satisfactory (r = .706), which indicates an adequate convergent validity of the questionnaire. A confirmatory factor analysis (CFA) was then conducted with a different sample of 322 patients, with bad adjustment results. It is recommended to verify the results, analyzing the questionnaire's psychometric properties with other samples of patients with chronic diseases.
