Building upon efficacious personalized normative feedback interventions, dynamic norms can be used to highlight the decreasing prevalence of alcohol use over time among young adults' peers, thereby increasing their motivation to change drinking consistent with the trend. Because limited research has examined dynamic norms feedback interventions for alcohol use, we examined the acceptability and initial efficacy of such an intervention, and potential iatrogenic effects of showing norms feedback about drinking to light drinkers and nondrinkers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Participants were 546 unvaccinated young adults ages 18\u201324 who completed a baseline survey, intervention, and 1\u2010month follow\u2010up assessment. Participants were block randomized to receive a brief web\u2010based dynamic norms intervention, with feedback content focused on either (a) alcohol\u2010related behaviors (intervention) or (b) COVID\u201019 vaccine behaviors (the attention\u2010matched control for the present study).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>On average, participants who received the alcohol intervention rated it as generally engaging, helpful, and acceptable, with the majority (90.8%) indicating that they would recommend it to a friend. Supporting initial efficacy, in generalized linear models controlling for demographics and baseline alcohol outcomes, at 1\u2010month follow\u2010up the alcohol intervention was associated with statistically and clinically significant reductions in all indices of perceived drinking norms, drinking quantity, drinking frequency, and driving after drinking occasions.
