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 BAS2 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-tostrong 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.
