Evidence for the Body Appreciation Scale's measurement equivalence/invariance between U.S. college women and men

Considered a measure of positive body image, the Body Appreciation Scale (BAS; Avalos et al., 2005) assesses acceptance of, favorable opinions toward, and respect for the body. Although the BAS was originally developed for and psychometrically examined with women, researchers are administering it to men and making gender comparisons. However, tests of measurement equivalence/invariance are needed to determine whether the BAS operates similarly for women and men. Therefore, in the present study, the BAS's cross-gender configural, factor loading, and intercept invariance was examined among 930 college women and men. The BAS demonstrated measurement equivalence/invariance between women and men, suggesting that gender comparisons can be made with confidence. Additional evidence was accrued for the convergent validity of the male version of the BAS, as it was related to men's dissatisfaction with muscularity, body fat, and height. These findings reinforce the structural and construct integrity of the BAS.

► Cross-gender measurement invariance of the Body Appreciation Scale (BAS) was tested.
► The BAS demonstrated configural invariance between women and men.
► The BAS demonstrated factor loading invariance between women and men.
► The BAS demonstrated intercept invariance between women and men.
► Convergent validity estimates supported the BAS as a body image measure for men.
