Early adolescent risk behavior outcomes of childhood externalizing behavioral trajectories

Abstract

Little is known about the early childhood indicators of adolescent risk. The link between trajectories of externalizing behavioral problems and early adolescent risk behavior was examined in a longitudinal sample of 875 child participants in the LONGSCAN studies. Five trajectory groups of children defined by externalizing behavior problems were identified: Low, Low-Medium, Moderate, Increasing-High, and High. After controlling for demographics and maltreatment, violent/delinquent behavior was significantly predicted by membership in the Moderate and Increasing-High problem behavior groups. Substance use in early adolescence was significantly predicted by membership in the High behavior problem group. These findings suggest that there is a great deal of continuity between patterns of externalizing behavior in childhood and risk-taking in early adolescence. Understanding the course of externalizing behavior in childhood can help identify children at particular risk for more serious behavioral problems in early adolescence. Copyright The Author(s) 2011.
