ALCOHOL ABUSE PREVENTION AMONG FRATERNITY MEN

学生酗酒被描述为“到目前为止美国大学面临的最严重的公共健康问题”。这项研究旨在促进针对兄弟会男性的改进的酒精滥用预防计划的发展。具体地说，这项研究试图评估两个国家兄弟会酒精滥用预防计划的影响，并检查理论上酒精消费决定因素的变化与兄弟会男性酒精消费水平下降之间的关系。这项研究的第一年将利用配对、随机化的前置设计来衡量10个兄弟会章节中预防活动的影响，而不是10个延迟干预控制章节。60个分会将参与第二年和第三年的调查。将根据酒精使用的减少以及假设的酒精行为决定因素的变化来评估影响，例如：控制过度酒精使用的章节的感知集体有效性、酒精消费预期以及关于酒精使用的感知规范。用于分析计划对这些措施的影响的主要统计程序将进行协方差分析，并进行修改，以说明各章内兄弟会成员的嵌套设计。在调查的第二和第三年，将从理论上建立过去的分析模型，说明这些变量在调节饮酒水平方面的因果路径，然后使用结构方程建模技术进行测试。

DESCRIPTION Students heavy drinking has been described as "by far the single most serious public health problem confronting American colleges". This research aims to facilitate development of improved alcohol abuse prevention programs for fraternity men. Specifically, this research seeks to evaluate the impact of two national fraternities' alcohol abuse prevention programs, and to examine associations between changes in theoretical alcohol consumption determinants and reductions in alcohol consumption levels among fraternity men. The first year of this research will utilized a matched pair, randomized pre-post design to measure the impact of prevention activities in 10 fraternity chapters, compared to 10 delayed intervention control chapters. Sixty chapters will participate in years two and three of the investigation. Impact will be assessed in terms of reduction in alcohol use as well as changes in hypothesized alcohol behavior determinants such as: perceived collective efficacy of the chapter in moderating excessive alcohol use, alcohol consumption expectancies, and the perceived norms regarding alcohol use. The primary statistical procedures used to analyze program impact on these measures will be analyzes of covariance with modifications to account for the nested design of fraternity members within chapters. During the second and third years of the investigation, past analytic models illustrating the causal pathways of these variables in moderating drinking levels will be theoretically created and then tested using structural equation modeling techniques.
