Resumo: The objectives of this study were to develop a unified Portuguese-language version, for use in Brazil and Portugal, of the Body Shape Questionnaire (BSQ) and to estimate its validity, reliability, and internal consistency in Brazilian and Portuguese female university students. Confirmatory factor analysis was performed using both original (34-item) and shortened (8-item) versions. The model's fit was assessed with χ²/df, CFI, NFI, and RMSEA. Concurrent and convergent validity were assessed. Reliability was estimated through internal consistency and composite reliability (α). Transnational invariance of the BSQ was tested using multi-group analysis. The original 32-item model was refined to present a better fit and adequate validity and reliability. The shortened model was stable in both independent samples and in transnational samples (Brazil and Portugal). The use of this unified version is recommended for the assessment of body shape concerns in both Brazilian and Portuguese college students.

El análisis factorial confirmatorio fue realizado usando tanto la versión original (34-ítems), como la reducida (8-ítems). El ajuste del modelo fue evaluado por los índices χ²/df, CFI, NFI y RMSEA. También se evaluó la validez concurrente y convergente. La fiabilidad se estimó a través de la consistencia interna y fiabilidad compuesta (α). La invariancia transnacional del BSQ se probó utilizando análisis multigrupo. El modelo original fue redefinido (32 ítems) para que presentara un mejor ajuste, así como una validez y fiabilidad adecuadas. El modelo reducido era estable, tanto en muestras independientes, como en las transnacionales (Brasil y Portugal). El uso de esta versión unificada se recomienda para la evaluación de aspectos relacionados con el cuestionario de figura corporal, tanto en estudiantes universitarias brasileñas, como portuguesas.Os objetivos do estudo foram desenvolver uma versão unificada em língua portuguesa do Body Shape Questionnaire (BSQ) e estimar sua validade, confiabilidade e consistência interna entre estudantes universitárias no Brasil e em Portugal. Foi realizada análise fatorial confirmatória utilizando a versão original (34 itens) e abreviada (8 itens) do questionário. O ajuste do modelo foi avaliado com χ²/gl, CFI, NFI e RMSEA. O estudo avaliou a validade concorrente e convergente. A confiabilidade foi estimada por meio da consistência interna e confiabilidade composta (α). A invariância do BSQ foi testada por análise de múltigrupos. O modelo original de 32 itens foi refinado para apresentar melhor ajuste e validade e confiabilidade adequadas. O modelo breve mostrou ser estável nas duas amostras independentes e em amostras transnacionais (Brasil e Portugal). O uso da versão unificada é recomendado para a avaliação de questões de imagem corporal em estudantes universitárias brasileiras e portuguesas.Reports in Public HealthCadernos de Saúde Pública2016-07-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6241Reports in Public Health; Vol. 32 No. 7 (2016): JulyCadernos de Saúde Pública; v. 32 n. 7 (2016): Julho1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6241/13244https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6241/13245Wanderson Roberto SilvaDavid CostaFilipa PimentaJoão MarocoJuliana Alvares Duarte Bonini Camposinfo:eu-repo/semantics/openAccess2024-03-06T15:29:12Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/6241Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:07:08.111251Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
