项目摘要

DESCRIPTION (provided by applicant): Colleges need effective universal prevention strategies to reach the substantial number of students who may be at risk for alcohol misuse and related harm. To address this need, Outside The Classroom developed a 2- 3 hour online course known as AlcoholEdu for college freshmen. Approximately 140 colleges are now mandating AlcoholEdu for their incoming freshmen despite the lack of research on its effectiveness. AlcoholEdu incorporates features of effective (Tier 1) intervention strategies recommended by the NIAAA Task Force on College Drinking. The proposed study will be the first to use a multi-campus experimental design to determine whether AlcoholEdu has beneficial and sustained effects on alcohol use and related harm among freshmen classes. We are proposing a randomized controlled study that will include 30 colleges. Fifteen of the colleges will be randomly assigned to implement AlcoholEdu for two consecutive freshmen classes in Fall 2008 and Fall 2009. Colleges that serve as controls in the 2008-09 academic year will also implement AlcoholEdu in the fall of 2009. Repeated cross-sectional surveys of freshmen classes in fall and spring semesters and two surveys of sophomore classes will allow us to examine both short-term and sustained AlcoholEdu effects. The specific aims of this study are: (1) To determine whether and to what extent AlcoholEdu reduces both immediate and longer-term alcohol misuse and related problems in the freshmen student population; (2) To determine if any observed effects of AlcEdu on alcohol misuse and related problems in the freshman student population are stronger if the program was also administered to the prior class of freshmen in the previous year; and (3) To assess the mediating effects on alcohol misuse and related problems of student-level psychosocial factors (e.g., normative beliefs, alcohol expectancies) targeted by AlcoholEdu. Mediating effects of sophomore class levels of alcohol use and related problems also will be examined for the 2009-10 freshmen class. Secondary aims of the study are to examine possible differences in AlcoholEdu's effects for colleges with (a) relatively high vs. low levels of student participation in the program, and (b) relatively high vs. low rates of baseline heavy alcohol use among incoming freshmen classes. We will also examine the possible combined effects of AlcoholEdu and other campus-wide prevention programs (e.g., social norming campaign) if there are enough colleges implementing AlcoholEdu with other campus-wide programs. Findings of this study will be of theoretical importance as no prior experimental studies have examined population-level effects of a web-based prevention program for college students that is based on social-cognitive theories of health behavior at the individual level. This study will also help college practitioners and administrators make an informed decision about whether to include AlcoholEdu as part of a comprehensive alcohol misuse and harm prevention strategy.

描述（由申请人提供）：大学需要有效的通用预防策略，以覆盖大量可能面临酒精滥用和相关伤害风险的学生。为了满足这一需求，Outside The Classroom 为大学新生开发了一个 2 至 3 小时的在线课程，称为“AlcoholEdu”。尽管缺乏对其有效性的研究，但目前大约有 140 所大学强制要求新生接受酒精教育。酒精教育结合了 NIAAA 大学饮酒工作组推荐的有效（第 1 级）干预策略的特征。拟议的研究将是第一个使用多校园实验设计来确定酒精教育是否对新生班级的酒精使用和相关危害具有有益和持续的影响。我们提议开展一项包括 30 所大学的随机对照研究。其中 15 所学院将被随机分配，在 2008 年秋季和 2009 年秋季连续两个新生班实施酒精教育。2008-09 学年作为对照的学院也将在 2009 年秋季实施酒精教育。重复横断面调查对秋季和春季学期新生班级的调查以及对二年级学生的两次调查将使我们能够检查酒精教育的短期和持续效果。本研究的具体目的是：（1）确定AlcoholEdu是否以及在多大程度上减少了新生群体中短期和长期的酒精滥用及相关问题； (2) 确定如果该计划也对前一年的前一届新生进行，则确定 AlcEdu 对新生群体中酒精滥用和相关问题的任何观察到的影响是否更强； (3) 评估酒精教育针对的学生心理社会因素（例如规范信念、酒精预期）对酒精滥用和相关问题的中介作用。 2009-10 年级新生班级也将研究二年级班级饮酒水平和相关问题的中介效应。该研究的次要目的是考察酒精教育对大学的影响可能存在的差异，其中（a）学生参与该计划的水平相对较高与较低，以及（b）新生中基线重度饮酒率相对较高与较低类。如果有足够多的大学与其他校园范围内的计划一起实施酒精教育，我们还将研究酒精教育和其他校园范围内的预防计划（例如社会规范运动）可能产生的综合影响。这项研究的结果将具有重要的理论意义，因为之前没有实验研究检验过基于个人健康行为的社会认知理论的大学生网络预防计划对人群的影响。这项研究还将帮助大学从业者和管理人员做出明智的决定，决定是否将酒精教育纳入全面的酒精滥用和伤害预防策略的一部分。
