The current study uses data from Project TAB (F31AA031607, R21AA031528). Participants were young adults who reported past 3-month risky drinking and experienced ≥1 alcohol-induced blackouts (AIB) (N=175, 52.6% female, 86.9% White, Mage=20.8). Participants wore TAC sensors and completed diary surveys twice a day over two three-weekend data collection bursts (six weekends total). The current study assesses whether parent norms are predictive of experiencing alcohol-induced blackouts among young adults.
