Résumé
To tested whether the efficacy of an internet-based brief intervention that included normative drinking feedback varied with estimations of the drinking of others. This study is a secondary analysis of a randomized controlled trial showing an intervention effect on weekly drinking. Participants were males with unhealthy alcohol use (mean age [SD]=20.8 [1.1]). Before the trial, participants were asked to estimate the percentage of men their age who drink more than they do. Using their self-reported drinking data, the "perceived" percentage of people their age and gender who drink more than they do, and data from Swiss statistics, we classified participants as overestimating (>+10%), accurately (-10% to +10%) or underestimating (
