Abstract

Background

Alcohol use and its related consequences are a public health problem among young adults. 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.

Methods

Participants were 546 unvaccinated young adults ages 18–24 who completed a baseline survey, intervention, and 1-month follow-up assessment. Participants were block randomized to receive a brief web-based dynamic norms intervention, with feedback content focused on either (a) alcohol-related behaviors (intervention) or (b) COVID-19 vaccine behaviors (the attention-matched control for the present study).

Results

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-month follow-up 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. Lighter drinkers showed no adverse iatrogenic effects.

Conclusions

Presenting alcohol-related personalized normative feedback using dynamic trends is a promising intervention for reducing alcohol use in a community sample of young adults. Further research clarifying the optimal presentation of dynamic norms is needed.

关于减少青少年饮酒的简短动态规范干预的可接受性、有效性和先天性影响的试点研究
饮酒及其相关后果是青壮年中的一个公共健康问题。在有效的个性化规范反馈干预的基础上,动态规范可用于强调青少年同龄人中饮酒率随时间推移不断下降的趋势,从而提高他们顺应趋势改变饮酒方式的积极性。由于针对饮酒的动态规范反馈干预的研究有限,我们研究了这种干预的可接受性和初步效果,以及向轻度饮酒者和不饮酒者展示饮酒规范反馈可能产生的先天性影响。
