  1. Study 1: 3577 observations nested within 71 participants across 10 groups; Study 2: 6729 observations nested within 147 participants across 23 groups. The zero-inflation sub-model of the hurdle model estimates the probability of an extra zero (no alcohol use) such that a positive estimate indicates a higher chance of no alcohol use. Perspective = perspective-taking; mindful = mindfulness.
