DESCRIPTION (provided by applicant): Heavy and problematic alcohol use is widespread on U.S. college campuses. Self-medication theory (SMT) posits that individuals exposed to trauma and resulting posttraumatic stress symptoms (PTSD) are at risk for heavy drinking and associated negative consequences. College students are no exception. Estimates of PTSD among college students are comparable to rates in the general adult population, and recent research has linked PTSD and alcohol-related negative consequences in college individuals. Data also reveal that the social environment (e.g., perceived peer norms, active peer influences) is a critical predictor of drinking in college, and has been linked to heavy drinking and deleterious outcomes in students. Yet, research has also shown that emotionally supportive peers are critical to the diminution and resolution of PTSD symptoms. As such, the drinking behaviors of these individuals may be highly influential for college students struggling with posttraumatic stress, and the extent to which one's emotional support group may consist of peers who are heavily alcohol involved may have a negative effect on drinking outcomes. PTSD symptoms, alcohol consumption, and peer interactions also are dynamic, varying over time and in their association with one another. The present project aims to assess the dynamic relationship between PTSD, alcohol behavior, and the influence of emotionally supportive peers at the daily level. Specifically, this study will investigate: (1) whether higher daily levels of PSD symptoms are associated with increased levels of daily alcohol consumption and reported alcohol-related consequences within individuals; (2) whether daily PTSD symptom expression and alcohol behavior is moderated by the density of drinkers in the emotional support group; and (3) whether the relationship between daily PTSD symptoms and daily alcohol behavior will be moderated by the daily drinking behavior of people in the emotional support group. Trauma-exposed college students (N=100) reporting heavy drinking and various PTSD responses (no symptoms, moderate symptoms, high symptoms) will complete a baseline assessment of individual difference variables. Participants will then complete 30 days of daily web-based surveys assessing alcohol use and related consequences, PTSD symptoms, and emotionally supportive peer behavior (peer alcohol use, peer level of emotional support). Using event-level methodology in combination with hierarchical linear modeling techniques will allow for a fine- grained and ecologically valid prospective examination of study hypotheses. Moreover, assessing peer influences at the daily level among high-risk drinkers is novel. Results have implications for informing SMT processes as well as for college administrators aimed at intervening with high-risk problem drinkers.

描述（由申请人提供）：在美国大学校园中，大量和有问题的饮酒是广泛的。自我用药理论（SMT）认为，暴露于创伤和创伤后应激症状（PTSD）的人面临大量饮酒和相关的负面后果的风险。大学生也不例外。大学生中PTSD的估计值与一般成年人口的比率相当，最近的研究将PTSD和与酒精有关的负面后果联系起来。数据还表明，社交环境（例如，感知到的同伴规范，积极的同伴影响）是大学饮酒的关键预测指标，并且与学生的饮酒和有害成果有关。然而，研究还表明，情感支持的同龄人对于减少和解决PTSD症状至关重要。因此，这些人的饮酒行为可能对因创伤后压力而苦苦挣扎的大学生具有很大的影响，以及一个人的情感支持小组可能由涉及大量酒精的同龄人组成的程度可能对饮酒结果产生负面影响。 PTSD症状，饮酒和同伴相互作用也具有动态性，随着时间的流逝而变化，并且相互关联。本项目旨在评估PTSD，酒精行为与每日情感支持同龄人的影响之间的动态关系。具体而言，这项研究将研究：（1）每天的PSD症状水平较高是否与每日饮酒水平的增加以及个人内部与酒精相关的后果有关； （2）情绪支持小组中饮酒者的密度调节日常PTSD症状表达和酒精行为； （3）情感支持小组中人们的日常饮酒行为会减轻日常PTSD症状与每日酒精行为之间的关系。暴露于创伤的大学生（n = 100）报告了大量饮酒和各种PTSD反应（无症状，中等症状，高症状）将完成对个体差异变量的基线评估。然后，参与者将完成30天的基于Web的调查，以评估酒精使用和相关后果，PTSD症状以及情绪支持性的同伴行为（同伴酒精使用，同伴的情感支持水平）。使用事件级方法与分层线性建模技术结合使用，将允许对研究假设进行细菌和生态有效的前瞻性研究。此外，评估高风险饮酒者每天的同伴影响是新颖的。结果对告知SMT流程以及旨在与高风险饮酒者进行干预的大学管理员有影响。
