Prospective associations between violent victimization, the quality of the parent-adolescent relationship, and the subsequent onset of violent aggression were examined. Using the National Longitudinal Study of Adolescent Health (Add Health), participants were divided into violent and non-violent cohorts based on whether they had committed an act…

Latent growth curve modeling employed data from a longitudinal study of 451 sibling families to examine parents, siblings, and family economics as factors in individual differences in the developmental course of interpersonal aggression during adolescence. Findings suggest that individual change in interpersonal aggression during adolescence can…
