Psychometric properties of the Japanese version of the Body Appreciation Scale-2 for Children (BAS-2C)

Abstract Despite the heightened interest in positive body image research in recent years, few studies have explored positive body image among children. Examining the Body Appreciation Scale-2 for Children (BAS-2C) using a different cultural sample than the original version would thus be beneficial in extending the research on this topic. This research aimed to validate the BAS-2C for use in Japan. The measures were administered to 243 children, and the participants completed the survey in their classrooms with the support of a teacher. The survey was repeated after four weeks. Confirmatory factor analysis showed that the one-factor structure was the same as that of the original version, and the BAS-2C was invariant across gender. Scores on the BAS-2C demonstrated good internal consistency and test-retest reliability over a four-week period. In addition, construct validity was accrued through the BAS-2C’s correlation with body dissatisfaction (among girls), self-esteem, and life satisfaction. Results indicated that the BAS-2C shows good psychometric properties among Japanese children, and supports further research into positive body image in this group.
