Zero-inflated negative binomial model (N = 1,599). Association between alcohol use at Time 1 and alcohol use at Time 2 as a function of sensitivity to punishment (SP) and receipt of an alcohol-related infraction at Time 1. T1 alcohol use (M = 14.96, SD = 13.61), T2 alcohol use (M = 14.35, SD = 13.27), and SP (M = 8.77, SD = 4.50) are centered at the mean.
