Heavy drinking in college increases risk for negative consequences. Among a national sample of high school abstainers and moderate drinkers, we hypothesized that the extent of heavy drinking among students on campus would be among the strongest predictors of first semester heavy drinking and consequences, relative to personal approval of alcohol use and sociability and impairment outcome expectancies. We expected these psychological factors to moderate effects of campus heavy drinking. Data from 90,455 abstainers and 97,168 moderate drinkers matriculating at 245 and 242 universities, respectively, were drawn from AlcoholEdu (EverFi, 2013), a web-based intervention completed by most first-year students at participating universities. Students reported alcohol use, approval, expectancies, and covariates prior to enrollment (Time 1). During the first semester (Time 2), abstinence, moderate drinking, or heavy drinking, and negative consequences experienced were reassessed. Campus heavy drinking reflected the percentage of other students attending the same school who engaged in heavy drinking at Time 2. In multilevel multinomial logistic regression models, campus heavy drinking was consistently among the strongest predictors of heavy drinking and consequences: It predicted an 83% and 82% increase in risk of heavy drinking and a 106% and 91% increase in risk of consequences among students who were abstainers and moderate drinkers at Time 1, respectively. There were few interactions among campus heavy drinking and psychological factors. Post hoc analyses supported that students did not self-select into heavier drinking environments. Campus heavy drinking is a key predictor of first semester alcohol use and an important intervention target. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

上大学时喝更多的同龄人会增加喝酒的风险和后果吗？前瞻性国家分析。

在大学里大量饮酒会增加负面后果的风险。在全国高中戒酒者和中度饮酒者的样本中，我们假设相对于个人对酒精使用，社交性和不良结果的认可，校园学生中的重度饮酒程度是第一学期重度饮酒及其后果的最强预测指标之一。期望。我们希望这些心理因素能够缓解校园大量饮酒的影响。来自AlcoholEdu（EverFi，2013年）的数据分别来自245家和242所大学的90,455名戒酒者和97,168名中度饮酒者的数据（EverFi，2013年），该网络干预是由参与大学的大多数一年级学生完成的。学生在入学前报告了饮酒，批准，期望和协变量（时间1）。在第一学期（时间2）中，重新评估了禁欲，适度饮酒或重度饮酒以及经历的负面后果。校园大量饮酒反映了同一时间在同一所学校就读的其他学生在时间2进行饮酒的百分比。在多层多项式Lo​​gistic回归模型中，校园大量饮酒始终是最严重的酗酒和后果预测指标：它预测为83％，在第一时间戒酒和中度饮酒的学生中，重度饮酒的风险增加82％，后果的风险分别增加106％和91％。校园酗酒与心理因素之间的相互作用很少。事后分析支持学生不要在较重的饮酒环境中进行自我选择。校园大量饮酒是第一学期饮酒的关键预测指标，也是重要的干预目标。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
