The prevalence of heavy drinking among college students and its associated health related consequences highlights an urgent need for alcohol prevention programs targeting 18 to 24 year olds. Nevertheless, current alcohol prevention programs in the Netherlands pay surprisingly little attention to the drinking patterns of this specific age group. The study described in this protocol will test the effectiveness of a web-based brief alcohol intervention that is aimed at reducing alcohol use among heavy drinking college students aged 18 to 24 years old.
METHODS/DESIGN: The effectiveness of the What Do You Drink web-based brief alcohol intervention will be tested among 908 heavy drinking college students in a two-arm parallel group randomized controlled trial. Participants will be allocated at random to either the experimental (N=454: web-based brief alcohol intervention) or control condition (N=454: no intervention). The primary outcome measure will be the percentage of participants who drink within the normative limits of the Dutch National Health Council for low-risk drinking. These limits specify that, for heavy alcohol use, the mean consumption cannot exceed 14 or 21 glasses of standard alcohol units per week for females and males, respectively, while for binge drinking, the consumption cannot exceed five or more glasses of standard alcohol units on one drinking occasion at least once per week within one month and six months after the intervention. Reductions in mean weekly alcohol consumption and frequency of binge drinking are also primary outcome measures. Weekly Ecological Momentary Assessment will measure alcohol-related cognitions, that is, attitudes, self-efficacy, subjective norms and alcohol expectancies, which will be included as the secondary outcome measures.
This study protocol describes the two-arm parallel group randomized controlled trial developed to evaluate the effectiveness of a web-based brief alcohol intervention. We expect a reduction of mean weekly alcohol consumption and frequency of binge drinking in the experimental condition compared to the control condition as a direct result of the intervention. If the website is effective, it will be implemented in alcohol prevention initiatives, which will facilitate the implementation of the protocol.

大学生重度饮酒的流行及其相关健康后果凸显出迫切需要针对 18 至 24 岁人群开展酒精预防计划。然而，荷兰目前的酒精预防计划却出人意料地很少关注这一年龄段的饮酒模式。本研究方案中描述的研究将测试一种针对 18 至 24 岁重度饮酒大学生的基于网络的简短酒精干预措施的有效性。
方法/设计：一项针对 908 名重度饮酒大学生的两臂平行组随机对照试验将测试基于网络的简短酒精干预措施的有效性。参与者将被随机分配到实验组（N=454：基于网络的简短酒精干预）或对照组（N=454：无干预）。主要结局指标是在荷兰国家健康理事会低风险饮酒的规范范围内饮酒的参与者比例。这些限制规定，对于重度饮酒，女性每周平均饮酒量不得超过 14 或 21 标准酒精单位，男性分别不得超过 14 或 21 标准酒精单位，而对于狂饮，每周至少一次在一个月和六个月内每周一次狂饮，不得超过 5 或更多标准酒精单位。每周生态瞬时评估也将衡量与酒精相关的认知，即态度、自我效能、主观规范和酒精期望，这些将作为次要结局指标。
本研究方案描述了为评估基于网络的简短酒精干预措施的有效性而开发的两臂平行组随机对照试验。我们预计实验组的平均每周饮酒量和狂饮频率会低于对照组，这是干预的直接结果。如果该网站有效，它将被纳入酒精预防计划，这将促进方案的实施。
