When we consider society’s fixation with physical attractiveness coupled with adolescent concerns about social acceptance, it seems inevitable that some young people develop a tendency to expect social rejection based on the way they look. This tendency has recently been referred to as appearance-based rejection sensitivity (appearance-RS; Park, 2007). Building upon the existing theory and research on rejection sensitivity and body dissatisfaction, and on two recent studies that examined the role of social relationships on appearance-RS (Bowker et al., 2012; Park, DiRaddo, & Calogero, 2009), the primary purpose of the studies reported here were to examine the specific and multiple roles of friends in appearance-RS. Following a review of the literature and the development of a modified version of the Appearance-RS Scale (Park, 2007) suitable for adolescents, the Adolescent Appearance-RS Scale (AA-RSS), two studies were conducted.
