Mobile Application Intervention Targeting the High Risk Drinking Practice of Prepartying

项目概要/摘要 拟议的研究项目解决了大学生大量饮酒的公共卫生问题 通过开发和测试一个创新的基于移动的应用程序，以针对特定的危险饮酒 这是一种被称为“准备派对”的行为，85%以上的大学生都有这种危险行为。筹备派对 包括在宿舍或校外宿舍快节奏的大量饮酒，然后外出过夜 学生们不可避免地喝得更多。80多项派对前研究的结果表明， 也许是已知的最危险的大学饮酒行为，导致后果在筹备活动， 继续饮酒和后果后，筹备活动，并提高全球饮酒水平， 与酒精有关的问题。然而，缺乏直接针对筹备缔约方的干预措施是缔约方在这方面的一个重大差距。 大学生饮酒研究领域，因为这样的方法可以解决和减少已知的行为 是最大的风险。对于拟议的研究，我们将开发和测试一个准备特定的简短的移动应用程序 旨在帮助学生减少聚会前行为的干预措施。我们首先开发 干预内容的基础上的理论和研究支持机制的变化，在简短的干预， 大学生和文件规范饮酒信息从500名大学生纳入 干预内容。然后，我们对14名重度饮酒的大学生进行了beta测试。 焦点小组的可行性和可接受性反馈将为最终的干预内容提供信息，并帮助我们 完善研究程序。然后，我们将在一项随机对照试验中对基于移动的干预进行初步测试， 500名大学生经常出现注意力缺陷（n = 250干预，n = 250注意控制），并确定 干预措施对（1）预防高消费水平和在此期间和之后的后果的有效性 在短期内筹备派对（即，干预前2周至干预后2周），以及（2） 在干预后一个月和三个月，降低学生的全球酗酒水平和后果。 最后，我们将评估假设的主持人已知有助于更大的风险，在筹备派对;主要是， 女学生，21岁以下的学生，酗酒者，以及那些有动机改变饮酒习惯的人， 从干预中获益最多。我们将测试一个假设的效果，即在聚会前饮酒的变化 干预后（基线至一个月）将解释观察到的全球饮酒和后果的变化 从基线到干预后三个月。这种针对具体筹备工作的方法扩大了全球范围， 干预措施，并改进有希望的事件特定的方法，只专注于不经常发生的 事件（例如，21岁生日，春假），针对流行的行为之前，多次饮酒 直接导致进一步的饮酒和问题。通过对潜在的担忧来源进行干预， 这是有史以来第一次为派对做准备，有可能极大地改变大学酗酒的文化。

Project Summary/Abstract The proposed research project addresses the public health concern of heavy drinking among college students by developing and testing an innovative mobile-based application to target the specific dangerous drinking behavior known as prepartying, a risky behavior practiced by upwards of 85% of college students. Prepartying involves fast-paced heavy drinking in residence halls or off-campus residences prior to going out for the night where students inevitably drink even more. Findings from over 80 prepartying studies suggest the behavior is perhaps the riskiest known college drinking behavior, leading to consequences during the prepartying event, to continued drinking and consequences after prepartying events, and to greater global levels of drinking and alcohol-related problems. Yet the lack of interventions directly targeting prepartying represents a major gap in the college student drinking research field, as such an approach could address and reduce the behavior known to be the greatest risk. For the proposed study, we will develop and test a prepartying-specific brief mobile-app intervention that is intended to help students reduce their prepartying behavior. We first develop the intervention content based on theory and research supporting mechanisms of change in brief interventions with college students and document normative drinking information from 500 college students for inclusion in the intervention content. We then beta test the intervention with a sample of 14 heavy drinking college students. Focus group feasibility and acceptability feedback will inform the final intervention content, as well as help us refine study procedures. We will then pilot test the mobile-based intervention in a randomized controlled trial of 500 college students who preparty frequently (n = 250 intervention, n = 250 attention control) and determine the efficacy of the intervention on (1) preventing heavy consumption levels and consequences during and after prepartying in the immediate term (i.e., pre-intervention two weeks to post-intervention two weeks), and on (2) reducing students’ global levels of heavy drinking and consequences one and three months post-intervention. Lastly, we will evaluate hypothesized moderators known to contribute to greater risk during prepartying; mainly, that female students, students under age 21, heavier drinkers, and those motivated to change their drinking will benefit the most from the intervention. We will test a hypothesized effect that changes in prepartying drinking post-intervention (baseline to one-month) will explain changes observed in global drinking and consequences from baseline to three-month post-intervention. This prepartying-specific approach expands on global interventions and improves upon promising event-specific approaches that only focus on infrequently occurring events (e.g., 21st birthdays, spring break) by targeting the popular behavior that precedes multiple drinking contexts and directly leads to further drinking and problems. By intervening at the potential source of concern, this first-ever prepartying intervention has the potential to greatly change the culture of heavy college drinking.
