Social Norms and Alcohol Prevention (SNAP)

描述（由申请人提供）：拟议研究的总体目标是测试计算机提供的个性化规范反馈在预防和减少大学生问题饮酒方面的功效。尽管社会规范的预防方法的广泛使用，方法的混淆阻止了个性化的规范反馈的影响的大小和持续时间的确定。此外，本研究的目的是评估性别特异性的规范参照，自我决定的个体差异，以及饮酒的原因作为干预效果的调节。这项研究还将确定规范信息对从不或很少喝酒的学生的影响。大学生饮酒的动机主要是社会因素，包括认为大量饮酒是“正常的”。“大学生高估了同龄人的饮酒量。据推测，这种扭曲导致许多学生比平时喝得更多。它也可能导致那些从不或很少喝酒的学生感到疏远和孤立。纠正规范性误解是社会规范预防方法的目标。这项研究将分三个阶段在两所大学进行。在第一阶段，将获得两个网站的描述性饮酒规范，并将其纳入基于网络的评估和干预计划。第二阶段将在大量饮酒的学生中实施为期3年的纵向疗效试验。学生将被随机分配到一个单一的个性化规范反馈，重复两年一次的反馈，或控制组。反馈组的学生也将被随机分配接受特定性别或非特定性别的反馈。第三阶段将评估规范性信息对从不/很少喝酒的学生的影响。学生将被随机分配接受社会规范营销信息，个性化的规范反馈，或评估。随访评估将确定基线后3个月和6个月时规范性信息的影响。第2和第3阶段的所有评估和干预措施都将以互联网为基础。这项研究将填补关于使用规范反馈预防和减少问题饮酒的重要知识空白，并将作为实施低成本基于互联网的个性化规范反馈干预措施的原型。

DESCRIPTION (provided by applicant): The overall objective of the proposed research is to test the efficacy of computer delivered personalized normative feedback in the prevention and reduction of problem drinking among college students. Despite the wide spread utilization of social norms prevention approaches, methodological confounding has prevented determination of the magnitude and duration of effect of personalized normative feedback. In addition, this research aims to evaluate gender specificity of the normative referent, individual differences in self-determination, and reasons for drinking as moderators of intervention efficacy. This research will also determine the impact of normative information on students who never or rarely drink. College student drinking is largely motivated by social factors, including the perception that heavy drinking is "normal." College students overestimate the alcohol consumption of their peers. This distortion is presumed to cause many students to drink more than they otherwise would. It may also contribute to feelings of alienation and isolation among students who never or rarely drink. Correction of normative misperceptions is the goal of social norms prevention approaches. This research will be conducted at two universities in 3 stages. In stage 1, descriptive drinking norms from both sites will be obtained and incorporated into a web based assessment and intervention program. Stage 2 will implement a 3-year longitudinal efficacy trial among heavy drinking students. Students will be randomly assigned to a single exposure of personalized normative feedback, repeated biannual exposure to feedback, or a control group. Students in the feedback groups will also be randomly assigned to receive gender specific or gender non-specific feedback. Stage 3 will evaluate the impact of normative information on never/rarely drinking students. Students will be randomly assigned to receive social norms marketing messages, personalized normative feedback, or assessment only. Follow-up assessments will determine the impact of normative information at 3-months and 6-months post baseline. All assessments and interventions in stages 2 and 3 will be Internet based. This research will fill important knowledge gaps regarding the use of normative feedback in preventing and reducing problematic drinking and will serve as a prototype for implementing low-cost internet based personalized normative feedback interventions.
