The Body Acceptance by Others Scale-2 (BAOS-2) was developed to assess overall perceived body acceptance by others. In two studies, we evaluated its structure, reliability and validity among young adults in China. In Study 1, 435 women and 322 men completed newly translated simplified Chinese versions of the BAOS-2 and Functionality Appreciation Scale (FAS), conceptually related body image questionnaires and demographic items. Exploratory factor analyses supported a 13-item unidimensional BAOS-2 structure across men and women. Internal consistency, test-retest reliability, convergent validity and discriminant validity were also supported. Study 2 (307 men, 396 women) replicated the original gender-invariant BAOS-2 structure in confirmatory factor analysis and bolstered evidence for convergent, discriminant and incremental validity. Predictive validity, examined via longitudinal analyses, indicated baseline BAOS-2 scores and/or concomitant changes in BAOS-2 scores over time were related to improvements on other positive and negative body image measures at a six-month follow-up. Supplementary analyses replicated the original unidimensional FAS factor structure and provided considerable support for its psychometrics across samples. In sum, this research supported psychometric properties of the BAOS-2 among young adults in China and underscored its potential utility in predicting changes in other body image experiences over time.
