AbstractConsidering the relevance of peer relationships in childhood development, a large body of longitudinal studies has established the predictive contribution of aggression and peer rejection to later dysfunction. However, few researchers have considered rejection by same-sex peers while describing the mechanism through which behavior and early peer experiences may result in future psychological maladjustment, including aggression. Nevertheless, sex segregation during childhood has been referred to as one of the most persistent and reliable developmental phenomena. We test two separate models establishing that, regardless of the previous level of aggression at age 5, peer rejection by conflicts and that these maladaptive behaviors will develop into subsequent aggressive behaviors. Three types of aggression (physical, verbal and indirect) and withdrawal behavior in social conflicts were tested as mediators in the association between rejection by same-sex peers at kindergarten, and later aggression and behavioral problems at age 9. The participants were 48 boys and 59 girls from ages 5 to 9, in eight classrooms in three Spanish state schools. Rejection by same-sex peers was calculated from individual sociometric data collected at the end of kindergarten. At age 7, the Peer Estimated Conflict Behavior Inventory (PECOBE) was used to measure negative responses to social conflicts. Lastly, at age 9, behavioral problems and aggressive behavior were assessed using the parents’ rating and a peer rating measurement instrument, respectively. Also, in order to control the previous aggression level at age 5, an observational measure was obtained for each participant. For both girls and boys, and after controlling the previous level of aggression at age 5, rejection by same-sex peers predicted aggressive behavior at age 9, whereas among boys only, rejection by same-sex peers also contributed to behavioral problems at age 9. Further, support was found for the proposed mediating processes. Indirect aggression, as a response to social conflicts, helped to account for the link between early rejection by same-sex peers and later aggressive behavior in girls. For boys, rejection by same-sex peers increased the likelihood of aggressive behavior (physical and indirect) in social conflicts, and these behaviors in turn contributed to both aggression and behavioral problems at age 9. Findings which enhance our understanding of the mechanisms that lead to risk behavior in girls and boys have the potential to inform gender-specific interventions aimed at preventing future problems.
