Adaptation of the abbreviated version of the Acceptance and Action Questionnaire - Social Anxiety for the Brazilian context

Abstract This study aimed to adapt and obtain valid evidence of the Brief Social Anxiety Acceptance and Action Questionnaire (B-SA-AAQ) for the Brazilian context. A total of 301 subjects (69.4% women) from the five regions of Brazil, aged between 18 and 64 years (M = 26.7; SD = 8.7), participated in the study. Exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) and the adequacy of the model were assessed using fit indices. The results indicated a satisfactory unidimensional structure (α = 0.92; ω = 0.91). Multigroup CFA demonstrated the invariance of the measurement between males and females. In addition, the scale scores showed significant correlations with external variables such as social phobia, psychological inflexibility, and emotional suppression. It was concluded that the results are favorable to the use of the B-SA-AAQ in Brazilian samples.
