Propiedades Psicométricas de la Escala de Activación Conductual para la Depresión (BADS) en una Muestra Mexicana

Abstract

The aim of this work was to assess the psychometric properties of the Behavioral Activation for Depression Scale (BADS) in a sample of Mexican University students. To this end, the scale was applied to 381 students of a private university. The results showed that, compared to both the original version in English and the Spanish adaptation developed in Spain, it is a valid and consistent scale. The dimensions of the original instrument were replicated in the confirmatory factor analysis. Criterion and discriminant validity was contrasted by means of correlations with the BDI-II, which yielded scores according to what was expected both for the total scale and for the different dimensions. An ordinal logistic regression analysis showed that BDI-II cut-off scores (minimal, mild, moderate, and severe depression) adequately predict BADS scores. Regarding the internal consistency, this sample reached a Cronbach’s alpha of .89 for the total scale and from .77 to .85 for its dimensions.
