Translation and validation of the Body Image Avoidance Questionnaire (BIAQ) for the Portuguese language in Brazil.

Brazilian researchers have not been provided with instruments with which to investigate body image avoidance behaviors. The aim of this study was to translate and validate the Body Image Avoidance Questionnaire (BIAQ) for Brazil. The translation, synthesis, back-translation, Brazilian questionnaire formulation, and pretest were carried out in the first phase of the study. The study of the scale's psychometric properties was conducted in the second phase of the study. Brazilian BIAQ has 13 items and good adjustment indexes. There was a greater adherence to the sampling data in the model in which the avoidance of body image is maintained by control strategies, by the refusal of body exposure, and by strategies that accommodate tension. This work is expected to enable the comparison of international data and the performance of multicultural studies on body avoidance behavior, expanding research possibilities in Brazil and worldwide.
