We aimed to characterize developmental patterns of involvement in alcohol use, delinquency, and interpersonal aggression in a normative sample of adolescents by applying multitrajectory group-based modeling. Using seven waves of data from a cohort sequential study spanning the 6th to 12th grades (n\ua0=\ua02,825; 50% girls), we identified four distinct trajectory groups: low risk (33%), declining peer aggressors (44%), peer and dating aggressors (13%), and multidomain high risk (10%). Across all comparisons, girls were more likely than boys to be members of the peer and dating aggressor group and less likely to be members of the multidomain high-risk group. Moreover, individual (self-control, negative emotionality), family (family violence, parental monitoring), and peer (substance use norms) distinguished class membership.R21 HD087781/HD/NICHD NIH HHS/United StatesR49CCV423114/CE/NCIPC CDC HHS/United States1R21HD087781-01/Eunice Kennedy Shriver National Institute of Child Health and Human Development/R01DA16669/Eunice Kennedy Shriver National Institute of Child Health and Human Development/2021-12-01T00:00:00Z32918776PMC77742448874vault:3634
