Effects of Physical Appearance Social Comparisons and Perceived Attainability of an Ideal Body on Body Dissatisfaction and Weight‐Management Behaviors Among Young Japanese Women

This study was designed to test a model in which tendencies to engage in physical appearance social comparisons and perceived ideal body attainability interact to predict body dissatisfaction, and are associated with weight‐control behaviors (WCBs) as past studies have rarely examined perceived attainability in their analytic models. College women (N = 297) from two universities in Japan completed a paper‐and‐pencil survey. A path analysis revealed that appearance comparisons were positively associated with body dissatisfaction over and above the effects of body mass index and self‐esteem. Body dissatisfaction, in turn, was positively related to low‐risk, moderate‐risk, and high‐risk WCBs. There was a significant interaction effect between appearance comparison and attainability, but the nature of the interaction was the opposite from our expectation: the positive association between appearance comparison and body dissatisfaction was more pronounced among women who reported higher confidence in attaining an ideal body, whereas this association was nonsignificant for those with low confidence in attaining an ideal body. Finally, perceived ideal body attainability was directly and positively related to low‐risk and moderate‐risk WCBs.
