On the basis of predictions from social comparison theory (L. Festinger, 1954) and informed by findings from the social comparison and eating disorder literatures, hypotheses were tested regarding the social comparison behaviors of women with eating disorder symptoms and their asymptomatic peers. Results indicated differentiating social-cognitive processes for these groups. First, a greater tendency to engage in everyday social comparison predicted the presence of eating disorder symptoms. Second, social comparisons of one's own body to images of other women's bodies using a range of shapes and sizes also differentiated these 2 groups, with more self-defeating self-appraisals predicting the presence of eating disorder symptoms. Finally, self-esteem partially mediated the relationship between body-related social comparisons and eating disorder symptom status. Results are discussed in terms of their implications for research and practice.
