Measurement invariance of the SATAQ-4 in Black and White undergraduate women.

The Sociocultural Attitudes Towards Appearance Questionnaire-4 (SATAQ-4) is a widely used measure of sociocultural factors affecting body image. Despite evidence sociocultural appearance ideals and pressures might differ between White and Black women, the SATAQ-4's invariance has not been formally evaluated. The current study examined its measurement invariance across White and Black college women. Women (N = 730; 68.5 % White, 31.5 % Black), recruited from a large, public university in the United States completed measures online. Confirmatory factor analysis (CFA) showed the original five-factor structure was adequate in each group, and it appeared equivalent across groups. However, full metric invariance was not supported. Factor loadings on one item differed, suggesting differences in how this item contributed to thin-ideal internalization between groups. Similarly, one threshold differed, suggesting Black women who mostly agreed they wanted a "very thin" body had more thin-ideal internalization than White women with the same rating. These results suggest comparisons between these groups on the thin-ideal internalization subscale should be interpreted cautiously, as group differences could reflect some measurement bias. Given appearance pressures and ideals extend beyond thinness, particularly for Black women, future research should consider refining or developing culturally sensitive measures, to enhance relevance between and within racial/ethnic groups.
