title: Joint trajectories of gambling, alcohol and marijuana use during adolescence: a person- and variable-centered developmental approach.
abstract: The usefulness of Moffitt's (1993) [Moffitt, T. E. (1993). Adolescence-limited and life-course-persistent antisocial behavior: A developmental taxonomy. Psychological Review, 100, 674-701.] theory of antisocial behavior was examined regarding gambling, alcohol and marijuana use. We assessed 903 Caucasian boys' developmental trajectories of these behaviors annually from age 11 through age 16. Severity of problems with these behaviors were assessed at ages 17 and 23. As correlates of these behaviors, teacher-rated personality and self-reported parenting were assessed at age 10. Self-reported autonomy was measured at ages 11 and 14. A cluster analysis on the correlates yielded two clusters. Membership in the cluster without adult problems was associated with either late onset of gambling and/or alcohol use trajectories or consistently low involvement in each of the behaviors. This cluster may correspond to Moffitt's adolescence-limited group and uninvolved adolescents, respectively. Membership in the cluster with subsequent adult problems was associated with early initiation of at least one of the three behaviors and involvement in each of them during adolescence. This cluster may correspond to Moffitt's life-course-persistent group. Findings indicate that early assessment of correlates used in the cluster analysis may be useful for screening and preventive purposes.
