Abstract
Este estudio tenía dos objetivos. Primero, analizar el rendimiento diagnóstico de la versión española del Inventario para la Depresión de Beck–Segunda Edición (BDI-II) en una muestra de pacientes con trastornos psicológicos y, segundo, examinar si las soluciones unifactoriales y bifactoriales del BDI-II encontradas previamente en muestras similares son replicables y, de ser así, analizar la contribución relativa del factor general y de los dos factores específicos a la varianza del BDI-II. El BDI-II, junto con el módulo de los trastornos del estado de ánimo de la Entrevista Clínica Estructurada para los Trastornos del Eje I del DSM-IV (SCID-I VC) y un listado de cotejo de síntomas depresivos completado por el clínico, fueron aplicados a una muestra española de 322 pacientes adultos ambulatorios con diversos trastornos psicológicos. Tomando como criterio el diagnóstico clínico basado en la SCID-I VC y el listado de cotejo de síntomas depresivos, el BDI-II demostró un rendimiento diagnóstico aceptable para discriminar entre pacientes con trastorno depresivo mayor y pacientes sin depresión. Los análisis factoriales indicaron que el BDI-II mide una dimensión general de depresión compuesta por dos factores relacionados (somático y cognitivo), pero estos factores apenas explicaban varianza adicional más allá de la puntuación global.
This study had to aims. The first aim was to analyze the diagnos-tic performance of the Spanish version of the Beck Depression Inventory–Second Edition (BDI-II) in a sample of patients with psychological disor-ders. The second aim was to examine whether the one- and two-factor so-lutions previously found for the BDI-II in similar samples are replicable, and, if it is so, to analyze the independent contribution of the general factor and the two specific factors to the variance of the BDI-II. The BDI-II, along with the mood disorder module of the Structured Clinical Interview for DSM-IV Axis I disorders, Clinical Version (SCID-I VC) and a clinician-administered checklist for depressive symptoms, were administered to a Spanish sample of 322 adult outpatients with a variety of psychological dis-orders. Taking as a criterion the clinical diagnosis based on the SCID-I VC and the checklist for depressive symptoms, the BDI-II showed an accept-able diagnostic performance to discriminate between patients with major depressive disorder and those without depression. Factor analyses sug-gested that the BDI-II assess a general depression dimension composed of two related factors (somatic and cognitive symptoms), but these factors hardly explained any additional variance beyond accounted for by the full-scale score.
