Adaptação transcultural e validação do sociocultural attitudes towards appearance questionnaire – 3 (SATAQ – 3) para a população brasileira

Abstract

Body image is characterized as an ever-changing, multifaceted construct. The investigation of its perceptual (perception and interpretation of sensory stimuli) and attitudinal (beliefs, behaviors and attitudes regarding the body) components has become a recurrent theme in diverse areas of research which make use of specific tools to assess such components. However, there are few validated instruments to use with the Brazilian population for the investigation of the Body Image construct, primarily its cognitive component, which refers to the investment in physical appearance. A new line of study has been dedicated to the transcultural adaptation of tools, originally developed for other cultures, so that they can be used in the Brazilian context. The aim of this study was to perform the transcultural adaptation (translation and validation) of the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) for the young Brazilian population, both male and female. This dissertation is divided into two articles. The first, “Semantic Equivalence and Assessment of the Internal Consistency of the Brazilian Portuguese Version of the Sociocultural Attitudes Towards Appearance Questionnaire-3”, describes in detail the translation process of the SATAQ-3 from English into Portuguese, its retrotranslation, and the semantic equivalence between both versions. Moreover, in this article, traces of good psychometric qualities are presented through Cronbach’s alpha coefficient values higher than 0.9, for both men and women. In the second article, "Factorial Structure of the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) among Young Brazilians”, the assessment of the psychometric qualities of the SATAQ-3 in a sample composed of college students of both sexes is presented. The validity of the construct was assessed through Exploratory and Confirmatory Factorial Analysis, while its concurrent validity was evaluated through the comparison of the scores obtained in the Body Shape Questionnaire and in the Tripartite Influence Scale. The SATAQ-3 also presented good stability from the performance of the test-retest, as well as proper internal consistency both for the entire scale and for its dimensions: general internalization, information, pressure, athletic internalization and issues regarding reverse score. In conclusion, the Sociocultural Attitudes Towards Appearance Questionnaire-3 is ready to be used in samples of the young Brazilian population in order to investigate the cognitive component of Body Image in such population.
