Abstract
Few studies have analyzed theoretical model of depression through the Beck Depression Inventory II (BDIII) in Spanish-speaking adolescents. This research had two aims: 1) to know the fit of two BDI-II factor models in community Mexican adolescents, the one-dimension model and the Beck et al. (1996)’s original model posing the Cognitive-Affective and Somatic-Vegetative factors, and 2) to examine model invariance across sexes with the best-fitting model. In two studies, 1010 and 610 adolescents participated, respectively, who completed the BDI-II. Through CFA the two factor structures were tested and, by means of multi-group CFA, invariance analysis across sexes was performed. Results revealed superiority of the two-factor model in both studies, without differences between women and men. These findings lead to evidence for Beck’s theory of depression and construct validity of the BDI-II in adolescents.
