Note. N = 506. Sex was coded 0 = men, women = 1. IAT = Implicit Association Test. IATs were scored such that higher scores indicate stronger associations with the concepts in the IAT’s name. Bolded values indicate statistically significant IAT scores Consumption = self-reported number of drinks consumed on a typical week. Lagged models were run such that each possible lag (from 2 to 7) was evaluated using the following strategy: T_j+2 drinking = T_j IATs, where j = a given assessment time point. Exp (b) = the exponentiated coefficient.
