Abstract
Thinness is considered as one type of adornment; as such, it has a psychological function for others. Thus the drive for thinness and dieting were investigated from the viewpoint of impression management. Study 1 investigated a model that the need for approval affects dieting through the outcome expectancies of others' evaluations and the drive for thinness. The results of structural equation modeling indicated high validity for this model. Study 2 investigated the moderating role of self-esteem in the relationship between positive/negative outcome expectancies of others' evaluations and the drive for thinness. The results showed that self-esteem did not act as a moderator between the two components and the drive for thinness.
