PROJECT SUMMARY One in three young adults engage in high intensity drinking (HID; 8+ drinks for women/10+ for men) in the past year, placing them at risk for serious acute consequences of alcohol use (e.g., severe injury, overdose). Further, one third to one half of young adult drinkers report alcohol-induced blackouts (AIB), an outcome distinct from HID episodes. Most research to date on HID and AIB has been cross-sectional, retrospective, and conducted exclusively in college students, revealing little about specific drinking events leading to HID or AIB. Needed also are objective indicators of the topography of drinking during these events, which is feasible with biosensor technology. Understanding more about drinking patterns, proximal antecedents and consequences of HID and AIB is imperative to the continued development and refinement of effective interventions for the most at-risk drinkers. The specific aims of this study are to: (1) elucidate the topography of drinking at the event-level during naturally occurring drinking events characterized by HID and/or AIB, using both self-reported drinking captured via ecological momentary assessment (EMA) and objective biosensor data; (2) determine event-level behavioral antecedents (pregaming, drinking games, protective behavioral strategies) and psychosocial antecedents (drinking motives, willingness, intentions, affect, social context), as well as positive and negative consequences of HID events; (3) isolate event-level factors that increase AIB risk beyond level of intoxication (co-use of other drugs, inadequate sleep, willingness, intentions); and (4) examine changes in frequency of and associations among HID, AIB, and related negative consequences across three annual assessments. First, key informant interviews (n=20-28) will be used to gather data on the relevance of theoretically-based cognitive and behavioral factors, social context, affect and other factors in the prediction of HID, as well as to identify consequences of HID for young adults. Next, in a measurement burst design, 200 young adults will complete in-person assessments and three 30-day bursts of daily EMA assessments at 12-month intervals, in combination with objective measurement of alcohol consumption using biosensor technology. We seek to differentiate the event-level predictors and outcomes of HID and AIB relative to all other drinking events, and relative to heavy episodic drinking (4+/5+ drinks), in order to isolate what places an individual at unique risk for these particularly concerning outcomes. Multilevel models will be used to determine predictors and outcomes as a function of whether each drinking event is characterized by HID or AIB. The results of the proposed research will provide novel information on proximal predictors of these two public health concerns among young adults. This innovative study will help to determine motivational targets for interventions, and in doing so, provide theoretical and empirical bases for designing preventive interventions to reduce HID, AIB and other severe alcohol-related consequences.

项目摘要 过去三分之一的年轻人从事高强度饮酒（HID;过去的8岁以上的女性饮料/10多种饮料） 一年，将他们危害饮酒的严重急性后果（例如，严重损伤，用药过量）。 此外，三分之一至一半的年轻成年饮酒者报告了酒精引起的停电（AIB），结果 与HID情节不同。迄今为止，关于HID和AIB的大多数研究都是横断面的，回顾的，并且 仅在大学生中进行，几乎没有透露导致HID或AIB的特定饮酒活动。 所需的客观指标是这些事件中饮酒的地形的客观指标，这是可行的 生物传感器技术。了解更多有关饮酒模式，近端先例和后果的了解 HID和AIB的持续发展和改进是对有效干预措施的必要 大多数高危饮酒者。这项研究的具体目的是：（1）阐明在 在自然发生的饮酒事件中以HID和/或AIB为特征的事件级别，使用两者都自我报告 通过生态瞬时评估（EMA）和客观生物传感器数据捕获的饮酒； （2）确定 事件级的行为先例（预挑选，饮酒游戏，保护性行为策略）和 心理社会的先例（饮酒动机，意愿，意图，情感，社会环境）以及积极 和HID事件的负面后果； （3）隔离事件级别的因素，这些因素将AIB风险增加到 中毒（其他药物的共同使用，睡眠不足，意愿，意图）； （4）检查变化 三个年度的HID，AIB和相关负面后果之间的频率和关联 评估。首先，将使用关键的线人访谈（n = 20-28）来收集有关相关性的数据 基于理论上的认知和行为因素，社会环境，影响和其他因素，在HID的预测中， 以及确定HID对年轻人的后果。接下来，在测量爆发设计中，200年轻 成人将完成面对面评估，并在12个月以前的每日EMA评估进行3次30天爆发 间隔，结合使用生物传感器技术对酒精消耗的客观测量。我们 寻求与所有其他饮酒相对于所有其他饮酒的事件级的预测因素和HID和AIB的结果 事件，以及相对于大量的情节饮酒（4+/5+饮料），以隔离个人在什么位置 这些尤其是关于结果的独特风险。多级模型将用于确定预测变量 结果是每个饮酒事件是否以HID或AIB为特征。结果 拟议的研究将提供有关这两个公共卫生问题的近端预测因素的新信息 在年轻人中。这项创新的研究将有助于确定干预措施的动机目标 这样做，提供理论和经验基础，以设计预防干预措施以减少HID，AIB和 其他严重的与酒精有关的后果。
