Despite the substantial influence these acute alcohol-related problems cause globally, past research has failed historically to capture the dynamic nature of drinking events, including how multiple factors (ie, individual, group, and environmental) interact to affect event-level intoxication. Fortunately, technology (eg, transdermal alcohol monitors) and smartphone surveys have provided researchers with new avenues to measure the complex nature of alcohol consumption. This paper presents the methods of a pilot study that sought to measure event-level alcohol consumption in a natural drinking group of college students. Ten groups of friends (N=49) were followed for 2 weeks with daily diary surveys, continuous activity trackers, hourly geographic ecological momentary assessments (EMAs) on 4 separate drinking occasions, and a transdermal alcohol monitor during one group-based social event. On average, participants responded to > 75% of both daily diaries and EMAs and were compliant with activity trackers on 96% of monitoring days. Over 90% of the sample had usable transdermal data and after smoothing, peak transdermal alcohol contents ranged from 0.13 to 0.395 during the observation evening. The lessons learned during this pilot study can provide a building block for future work in this area, especially as data collection in alcohol research rapidly advances.
尽管这些与急性酒精相关的问题在全球范围内造成了巨大影响，但过去的研究在历史上未能捕捉到饮酒事件的动态性质，包括多个因素（如个人、群体和环境）如何相互作用影响事件级别的醉酒程度。幸运的是，技术（例如，皮肤酒精监测器）和智能手机调查为研究人员提供了新的途径来衡量饮酒行为的复杂性。本文介绍了一项试点研究的方法，该研究旨在测量大学生自然饮酒群体中的事件级饮酒量。 10 组朋友（N=49）接受了为期 2 周的日常日记调查、连续活动追踪器、4 次单独饮酒时的每小时地理生态瞬时评估（EMA）以及一次群体社交活动时的皮肤酒精监测器。 平均而言，参与者对日常日记和 EMA 的回复率>75%，活动追踪器的依从性为 96%的监测日。超过 90%的样本有可用的皮肤酒精数据，经过平滑处理后，观察晚上的皮肤酒精含量峰值范围在 0.13 到 0.395 之间。 这项试点研究中获得的经验教训可以为该领域的未来工作提供基础，特别是随着酒精研究中的数据收集迅速发展。
