Social Network Sites, Friends, and Celebrities: The Roles of Social Comparison and Celebrity Involvement in Adolescents' Body Image Dissatisfaction

This study applies the social comparison theory to examine the effects of adolescents' engagement in comparison with friends and celebrities on social network sites (SNSs) on (a) their body image dissatisfaction (BID) and (b) their drive to be thin (DT) or muscular (DM). The study also examines celebrity involvement as an antecedent of the outcome variables. Data were collected through a survey of 1,059 adolescents in Singapore. Regression analyses indicate that SNSs use was related to adolescents' BID. Specifically, social comparison with friends on SNSs was significantly associated with adolescents' BID, DT, and DM. Gender differences were also observed social comparison with celebrities was significantly associated with BID and DT among female adolescents. Celebrity involvement was significantly associated with male BID. Theoretical and practical implications were discussed.
