Alcohol use among adolescents and emerging adults is an important public health issue requiring prevention approaches. Herein, we describe outcomes from a randomized controlled trial testing the efficacy of group-based social media interventions targeting risky drinking among youth.
Using social media advertisements to screen potential participants, we recruited 955 youth (ages 16-24) reporting recent risky drinking. After completing a baseline assessment, participants were randomized to 8-week secret Facebook group conditions: Social Media Intervention + Incentives for engagement, Social Media Intervention only, and attention-placebo control. Electronic coaches trained in motivational interviewing facilitated interaction in intervention groups. Primary outcomes include past 3-month alcohol use and consequences over 3-, 6-, and 12-month follow-ups. Secondary outcomes include other drug use, consequences, and impaired driving. We also measured intervention engagement and acceptability.
The interventions were well-received, with significantly greater acceptability ratings and engagement in the SMI+I condition relative to other groups. In adjusted analyses, there were no significant differences between interventions and control on alcohol-related outcomes, with all groups showing reductions. Regarding secondary outcomes (70.4% used other drugs), compared to control, the incentivized group reduced other drug use, consequences, and cannabis-impaired driving; the non-incentivized group did not significantly differ from the control condition.
Among this predominantly poly-substance using sample, findings were mixed, with significant effects of the incentivized social media intervention on drug (but not alcohol) outcomes. Future studies are needed to further refine social media-delivered interventions to reduce alcohol and other drug use.

青少年和刚成年人群体的酒精使用问题是一个重要的公共卫生问题，需要采取预防措施。在此，我们描述了一项随机对照试验的结果，该试验测试了针对青年群体危险饮酒行为的基于群体的社交媒体干预措施的效果。
我们通过社交媒体广告筛选潜在参与者，招募了 955 名（年龄 16-24 岁）报告近期危险饮酒行为的年轻人。在完成基线评估后，参与者被随机分配到为期 8 周的秘密 Facebook 群组条件：社交媒体干预+参与激励、仅社交媒体干预和注意安慰剂对照。接受动机访谈培训的电子教练促进了干预组的互动。主要结果包括过去 3 个月的饮酒量和 3、6 和 12 个月随访期间的后果。次要结果包括其他药物使用、后果和驾驶障碍。我们还测量了干预的参与度和可接受性。
干预措施受到了好评，与其他组相比，SMI+I 条件下的可接受性评分和参与度显著更高。在调整后的分析中，干预组与对照组在酒精相关结果上没有显著差异，所有组都显示出减少。关于次要结果（70.4%的人使用其他药物），与对照组相比，激励组减少了其他药物的使用、后果和大麻驾驶障碍；非激励组与对照组相比没有显著差异。
在这个主要是多物质使用者的样本中，结果喜忧参半，激励型社交媒体干预对药物（而非酒精）结果有显著影响。需要进一步研究进一步完善社交媒体提供的干预措施，以减少酒精和其他药物的使用。
