The current study aimed to examine whether body surveillance mediated the relation between social comparison and selfie behaviors, and whether this mediating process was moderated by self-esteem. A sample of 339 female adolescents were recruited to participate in the present study and completed self-report measures of selfie behaviors, upward and downward appearance comparisons with peers, self-objectification and self-esteem. Results indicated that body surveillance mediated the association between upward physical appearance comparison and selfie behaviors. In addition, self-esteem moderated the relation between body surveillance and selfie behaviors. These findings add to the extant literature by suggesting that selfies may be some new ways of body surveillance and physical appearance comparison, which have some theoretical and practical implications.
