O objetivo deste estudo foi traduzir e adaptar culturalmente o Questionário de Atitudes Socioculturais em Relação à Aparência-4 (SATAQ-4) para a língua portuguesa e avaliar sua validade e confiabilidade quando aplicado a estudantes brasileiros. Realizou-se a validação de face, de conteúdo e pré-teste. Para a avaliação do índice de incompreensão, participaram do pré-teste 91 estudantes de três países de língua portuguesa (25 brasileiros, 37 portugueses e 29 moçambicanos). A validade de construto foi estimada utilizando-se estratégia confirmatória com os índices razão de qui-quadrado pelos graus de liberdade (χ²/gl), comparative fit index (CFI), Tucker-Lewis index (TLI) e root mean square error of approximation (RMSEA). A confiabilidade foi estimada. A invariância foi estimada para amostras independentes, para o sexo e presença/ausência de sobrepeso/obesidade. Todos os itens do SATAQ-4 foram compreendidos pelos estudantes do pré-teste. No estudo principal, participaram 1.051 universitários brasileiros (idade = 20,9 anos; DP = 2,4; 66,4% mulheres). O SATAQ-4 apresentou adequada validade (χ²/gl = 8,39;
CFI = 0,98; TLI = 0,98; RMSEA = 0,08) e confiabilidade (alfa de Cronbach = 0,84-0,95) na amostra. O modelo apresentou invariância entre amostras independentes e foi não invariante segundo sexo e presença/ausência de sobrepeso/obesidade. Conclui-se que o SATAQ-4 é um instrumento válido e confiável para amostra de universitários brasileiros, sendo uma alternativa para a avaliação das atitudes socioculturais em relação à aparência nesta população.
ABSTRACT: The aim of this study was to translate and culturally adapt the Sociocultural Attitudes Towards Appearance Scale-4 (SATAQ-4) to the Portuguese language and assess its validity and reliability when applied to Brazilian students. Face, content, and pretest validity were assessed. In order to assess the levels of misunderstanding, a pretest was performed with 91 students from three Portuguese-speaking countries (25 Brazilians, 37 Portuguese, and 29 Mozambicans). Construct validity was estimated using a confirmatory strategy with chi-square by degrees of freedom ratio (χ²/df), comparative fit index (CFI), Tucker-Lewis index (TLI), and root mean square error of approximation (RMSEA). The reliability was estimated. Invariance was estimated for independent samples, for sex and presence/absence of overweight/obesity. Students participating in the pretest understood all the items in SATAQ-4. Participation in the main study included 1,051 Brazilian university students (age = 20.9 years (SD = 2.4), 66.4% women). SATAQ-4 presented adequate validity (χ²/df = 8.39; CFI = 0.98, TLI = 0.98, RMSEA = 0.08) and reliability (Cronbach’s alpha = 0.84- 0.95) in the sample. The model showed invariance between independent samples and was not invariant according to sex or presence/absence of overweight/ obesity. In conclusion, SATAQ-4 is a valid and reliable instrument for a sample of Brazilian university students, as an alternative for assessing sociocultural attitudes towards appearance in this population.
