Development of Japanese version of the Body Appreciation Scale-2

Abstract

This study developed a Japanese version of the Body Appreciation Scale-2 (BAS-2), a measure for a comprehensive assessment of positive body image, and investigated its reliability and validity. The results of confirmatory factor analysis showed that, like the original version, the Japanese BAS-2 had a one-factor structure and invariance across gender. Body appreciation scores had good internal consistency, test-retest reliability, and construct validity. Furthermore, the scale exhibited incremental validity by predicting psychological elements (disordered eating, self-esteem, and satisfaction with life) above and beyond body dissatisfaction. Thus, the BAS-2 is suitable for the assessment of positive body image in the Japanese population.
