Results from the study showed delinquent behavior and aggression decreasing normatively throughout childhood for those with and without EFD. However, those with EFD showed precocious resurgences moving into early adolescence. Findings from the study were robust in their consistency. Onset of drinking was more strongly tied to the developmental course of delinquent behavior than aggression, with predispositions having an especially important influence on adolescent outcomes for early drinkers only. Substantial literature has demonstrated that heightened risk for alcohol problems and later alcohol use disorder were associated with having had an EFD experience. This study sought to advance research on EFD as a proxy for early problem alcohol use, and its relation to continuity in antisocial behavior. Study participants consisted of 220 male children and their parents in a high risk for substance use disorder prospective study. Early first drinking was defined as having had a first drink by 12 to 14 years of age. Tables and references
