Rendimiento diagnóstico y estructura factorial del Inventario para la Depresión de Beck–Segunda Edición (BDI-II) en pacientes españoles con trastornos psicológicos

Abstract

Title: Diagnostic performance and factorial structure of the Beck Depres- sion Inventory-Second Edition (BDI-II). Abstract: 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.
