Tower of London Test, Visual Span Test) was not associated with hazards for any alcohol transition, nor were alcohol milestones associated with EF trajectories. Fourth, greater problematic alcohol use PGS was associated with increased hazards for suicidal ideation and the onset of conduct disorder symptoms; however, PGS for behavioral phenotypes were not significantly associated with alcohol transition hazards. Although the timing of typical developmental onsets and progressions of EXT, INT, and AUD may influence these longitudinal associations, these findings suggest that EXT symptomatology may promote accelerations across all stages of alcohol involvement while early INT may drive progression only to severe AUD and INT is more likely to arise following AUD.
