Note. Threshold coefficients represents contrasts at each level of the nominal drinking outcome, 0 = No drinking, 1 = Moderate drinking (1–4/3 drinks for men/women), 2 = Heavy drinking (≥ 5/4 drinks for men/women). Lower and Upper CI represent bootstrapped 95% Confidence Intervals; bolded effects are statistically significant. Predictors in top panel are held constant across thresholds. All effects are within-person at the daily level, with the exception of Age, Sex, AUD/CUD, and % marijuana use days, which were between person.
