Psychometric properties of a Mandarin Chinese version of the Body Appreciation Scale-2 among Chinese adolescents

In the present study, we explored the factor structure and psychometric properties of the Mandarin Chinese BAS-2 among adolescents residing in the Chinese mainland. Exploratory factor analysis in Study 1 (N = 790; 396 girls, 394 boys) supported the unidimensionality of the Mandarin Chinese BAS-2 among Chinese adolescents. Internal consistency reliability was upheld via McDonald's omega. Convergent validity was supported by its moderate-to-strong relationships with body satisfaction, functionality satisfaction, self-esteem, life satisfaction, positive affect, and negative affect, while its small-to-moderate correlation with social desirability provided somewhat weaker discriminant validity support. Criterion-related validity was upheld by its inverse correlation with eating disorder symptomatology and positive correlation with intuitive eating. It explained unique variance in self-esteem (for girls and boys), eating disorder symptomatology (for girls), and intuitive eating (for boys) beyond age, body satisfaction, and functionality satisfaction, providing incremental validity evidence. A subsample of 134 girls and 114 boys completed the Mandarin Chinese BAS-2 again after three months, and test-retest reliability was upheld. The confirmatory factor analysis in Study 2 (N = 337; 192 girls, 145 boys) replicated the unidimensional structure and supported measurement invariance across gender. Collectively, the present study supported the unidimensionality, reliability, and validity of the Mandarin Chinese BAS-2's scores among Chinese adolescents.
