Validación del Cuestionario Tridimensional para la Depresión (CTD) en población venezolana con enfermedades crónicas

Abstract

The aim of the present study was to validate the Tridimensional Depression Questionnaire (Jiménez y Miguel-Tobal, 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 State-Trait Anxiety Inventory, in a sample of 202 patients with diabetes mellitus, hypertension, and ano-rectal 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.
