Peer Groups and Broad Social Motives’ Influence on College Student Drinking: A Multimethod Approach Using Alcohol Administration and Daily Diary

摘要 大学生酗酒每年导致1500多人死亡21。因此，至关重要的是，我们 了解促进大学生过度饮酒的因素。最常见的是，大学生 报告饮酒是为了促进社交目的。虽然许多研究评估了那些为了社交而喝酒的人 奖励，较少的研究集中在个人是否对社会奖励更敏感 而不是其他奖励(例如金钱)。初步研究发现，这种广泛的社会动机(BSM)是 预测饮酒行为的变化，而不是社交饮酒动机。因此，进一步的探索 对患有BSM的人更容易酗酒的情况进行研究是合理的。这 一项研究建议通过观察BSM中的个体差异如何与不同的同龄人互动来填补这一空白 群体会导致更多的饮酒。此外，本研究将使用创新的多方法方法来帮助我们 了解与个人相比，团队环境中自我报告风险承担的变化是如何评估的 环境，以及在受控实验室环境中自我给药的饮酒量，可能会转化为自然主义 通过日常日记测量的行为。21岁以上的大学生(N=100)将被随机分配到 在他们的一群亲密朋友或一群其他大学同龄人中完成一个即兴饮酒范例。 然后，参与者将使用日常日记来报告他们在自然环境中的社交背景和饮酒行为。 这种多方法方法将使我们能够评估在实验室中评估的行为如何自然预测 在不受控制的环境中发生的行为。例如，我们将评估在自我保护方面的更大增长 在酒吧实验室环境中，从基线到进入同龄人小组后报告的风险承担将预测更高的风险 在日常日记中报告的大多数饮酒者是亲密朋友的夜晚饮酒。调查结果来自 这项研究可以确定高危学生群体，他们可能对社会回报和社交更敏感 对饮酒的影响。这是创新的，因为研究已经证明了社会动机的重要性 然而，在饮酒行为中，我们还没有确定预测谁最有可能参与的最好方法 饮酒是为了促进社交。这项研究与国家酒精研究所的战略计划是一致的 滥用和酒精中毒(NIAAA)，因为它对改进战略以防止酒精滥用和 在这个高风险的发育期与酒精相关的后果。这项研究也支持以下目标 NIAAA资助的研究加强了对公众的影响，因为这项研究可以帮助构建学院和大学 关于校园社交渠道的政策。该项目的资金将为新兴的 伦理学博士前研究员，高级和多方法研究方法，定量方法， 和职业发展。总体而言，这个项目将阐明奖励敏感度是如何特定于社会背景的 可能会影响饮酒行为，并对预防和大学饮酒公共政策产生影响。

ABSTRACT Alcohol misuse by college students results in over 1,500 deaths per year21. Thus, it is crucial that we understand factors that promote excessive alcohol use by college students. Most commonly, college students report drinking for social facilitation purposes. While much research has evaluated those who drink for social rewards, less research has focused on whether individuals may have greater sensitivity to social rewards versus other rewards (e.g. monetary). Preliminary studies have found this broad social motivation (BSM) to be predictive of changes in drinking behavior over and above social drinking motives. Thus, further exploration into the circumstances in which those with BSM are more susceptible to heavy drinking is warranted. This study proposes to fill that gap by looking at how individual differences in BSM may interact with different peer groups to lead to heavier drinking. Further, this study will use innovative multimethod approaches to help us understand how changes in self-reported risk-taking assessed in a group setting as compared to an individual setting, as well as self-administered amount of drinking in a controlled lab setting, may translate to naturalistic behavior as measured through daily diary. College students over the age of 21 (N=100) will be randomized to complete an ad-lib drinking paradigm in either a group of their close friends, or a group of other college peers. Participants will then use daily diary to report their social context and drinking behaviors in natural settings. This multimethod approach will allow us to evaluate how behavior assessed in the lab predicts naturally occurring behaviors in an uncontrolled setting. For example, we will assess whether greater increases in self- reported risk-taking from baseline to after entering peer groups in the bar lab setting will predict heavier drinking on nights when most drinking companions are close friends reported during daily diary. Findings from this study could identify a high risk group of students who may be more sensitive to social rewards and social influences on drinking. This is innovative because research has demonstrated the importance of social motives in drinking behavior, yet, we have not determined the best way to predict who is most likely to engage in drinking for social facilitation. This study is aligned with the strategic plan of the National Institute on Alcohol Abuse and Alcoholism (NIAAA), as it has implications for improving strategies to prevent alcohol misuse and alcohol-related consequences in this high risk developmental period. This research also supports the goal of NIAAA-funded research having enhanced public impacts, as this study could help frame college and university policies on campus social outlets. The funding of this project will provide substantial training to an emerging predoctoral researcher in ethics, advanced and multimethod approaches to research, quantitative methods, and career development. Overall, this project will shed light on how reward sensitivity specific to social context may influence drinking behavior, with implications for prevention and public policy for college drinking.
