Persistent conduct problems, which include aggressive, disruptive, and antisocial behaviors, are associated with a range of negative correlates and sequelae, including school failure and dropout, depression, and substance use. Problematic peer relationships, such as peer rejection and deviant peer affiliation (DPA), have been implicated in both the development and persistence of conduct problems. In particular, the impact of peer rejection has been highlighted in childhood, whereas the effects of DPA have received more attention during adolescence. Conduct problems, peer rejection, and DPA are dynamic processes that change across development, and understanding the relations among these processes is particularly important among contextually disadvantaged youth who are at elevated risk for aggression. Nevertheless, limited research has considered both peer rejection and DPA as they relate to conduct problems in a single study and even less research has looked at potential moderators of the relations among these processes. To address these gaps, I empirically evaluated a developmental model of conduct problems and peer processes, focusing on individual differences across childhood and adolescence. The goal of the present study was to examine continuity and discontinuity of trajectories of conduct problems and problematic peer relations from childhood through adolescence and to identify contextual factors that impact continuity/discontinuity of risk. Participants were 678 urban children recruited in fall of 1st grade for the second generation Prevention Intervention Research Center's Periodic Follow-up of Two Preventative Interventions. Aggression and peer rejection in childhood were modeled separately first, followed by modeling the joint trajectories of aggression and rejection. Four distinct joint trajectories of aggression-rejection in grades 1 to 3 were identified: high decreasing aggression-high stable rejection, low increasing aggression-moderate increasing rejection, moderate decreasing aggression-moderate decreasing rejection, and low stable aggression-low stable rejection. As with the childhood analyses, aggression and DPA in adolescence were modeled separately first, followed by modeling the joint trajectories of aggression and DPA. Three distinct joint trajectories of aggression-deviant peer affiliation in grades 6 to 12 were identified: high decreasing aggression-low stable DPA, moderate stable aggression-high stable DPA, and low stable aggression-low stable DPA. Next, latent transition patterns from high- and low-risk childhood aggression-rejection trajectories to adolescent aggression-DPA trajectories pointed to evidence for both continuity and discontinuity of risk along aggression-DPA trajectories. Introducing contextual variables (i.e., perceived neighborhood adversity, community violence exposure, and poor parental monitoring) into the transition model suggested that higher levels of contextual risk were associated with elevated risk for transition to higher-risk adolescent aggression-DPA classes (i.e., high decreasing aggression-low stable DPA, moderate stable aggression-high stable DPA). / Psychology
