Additional between-person group analyses
We explored overall group differences in drinking occasions and drinks per occasion and report these results in Supplementary Analyses D. We tested whether the intervention groups drank less frequently and had fewer drinks on active weeks, and across all weeks collapsed, relative to the control group. Briefly, we found no group differences in the frequency of drinking occasions (see Tables S3 and S5). The perspective-taking group reported fewer drinks per occasion relative to the control group in Study 1. However, we did not replicate these effects in Study 2 (see Tables S4 and S6). We are cautious to make strong claims about between-person effects given the possibility that random assignment did not fully overcome baseline differences between groups. In Study 1, we observed that the perspective-taking group reported drinking less frequently at baseline relative to the control group. Since we did not collect baseline drinking information for participants in Study 2, we cannot account for potential pre-existing differences between groups in Study 2 (see Table
