Prior studies have addressed the influence of individual-level demographic variables on relational aggression among children and adolescents, resulting in little information about effective points of intervention. This paper argues that the inherently social nature of relational aggression warrants an examination of the effects of peer social network features on these behaviors. Specifically, the paper reframes the literature linking two individual-level variables (sex and age) to relational aggression from a contextual perspective that considers peer social networks. Moreover, the paper offers implications regarding how these reframed findings can be applied to the development of effective prevention and intervention programs and future research efforts.Early characterizations and empirical studies of childhood aggression focused exclusively on physical (e.g., hitting, shoving, kicking) and verbal (e.g., threats of physical aggression, yelling) forms of aggression (see Parke and Slaby 1983 for review). In contrast, recent definitions of childhood aggression have recognized that children and adolescents may also inflict harm by damaging their peers' social relationships. This paper examines such relational forms of aggression. Specifically, in order to identify more effective points of intervention, the paper introduces a structural framework that considers the influence of peer social networks on relational forms of aggression among children and adolescents.Relational forms of aggression include deliberate behaviors designed to harm others through subtle injury to peer relationships such as rumor spreading, social exclusion, and betrayal of trust. Researchers have discussed these behaviors using three overlapping constructs: relational aggression (e.g., Crick and Grotpeter 1995), indirect aggression
