0143/2021 - Psychometric investigation of the Attention to Body Shape Scale in Brazilian adults Investigação Psicométrica da Escala de Atenção à Forma Corporal em adultos brasileiros
Os objetivos do estudo foram: desenvolver a versão em português da Attention to Body Shape Scale (ABS); estimar as propriedades psicométricas da ABS para dados brasileiros; comparar os escores da ABS entre os sexos e diferentes características amostrais. A versão em português foi desenvolvida seguindo protocolo padronizado. As validades fatorial e convergente foram avaliadas por índices de ajustamento e variância extraída média. A confiabilidade composta e o coeficiente alfa ordinal foram calculados. A invariância do modelo ajustado foi investigada em subamostras independentes por análise multigrupos. Os escores médios da ABS foram comparados entre as variáveis usando ANOVA two-way. Participaram 1.056 indivíduos (71% mulheres) com média de idade de 26,1 (DP=6,4) anos. O item 3 foi excluído da escala devido ao baixo peso fatorial. O modelo refinado apresentou boas propriedades psicométricas aos dados. Diferentes características contribuíram para a maior atenção com a forma corporal. A versão em português da ABS será útil para investigar a atenção com a forma corporal no Brasil. A validade e a confiabilidade dos dados sustentaram a adequação do modelo refinado. Características específicas foram relevantes para investigar a atenção com a forma corporal, portanto, serão úteis para futuros protocolos.

Abstract:
The objectives of the study were: to develop a Portuguese version of Attention to Body Shape Scale (ABS), estimate the psychometric properties of the ABS for Brazilian data, and compare the ABS scores between the sexes and the different sample characteristics. The Portuguese version was developed following a standardized protocol. The factorial and convergent validity were evaluated using goodness-of-fit parameters and average variance extracted. Composite reliability and ordinal coefficient alpha were calculated. The invariance of the fitted model was investigated across independent subsamples using multigroup analysis. The scores were compared between variables using two-way ANOVA. A total of 1,056 individuals (71% female) with a men age of 26.1 (SD=6.4) years participated in the study. Item 3 was removed due to low factor loading. The refined model presented good psychometric properties for the data. Different characteristics contributed to greater attention to body shape. The Portuguese version of the ABS will be useful to investigate attention to body shape in Brazil. The validity and reliability of the data supported the adequacy of the refined model. Specific characteristics influenced attention to body shape, and therefore, should be considered in future protocols.
