Tailored Web Program to Reduce At-Risk College Drinking

描述（由申请人提供）：很明显，在未成年大学本科生中，迫切需要有效的干预措施来预防/减少危险饮酒（ARD；将健康置于危险境地的数量和频率的组合）。目前在美国，平均每天有三名大学生死于与酒精有关的车祸，而成千上万的大学生则是与酒精有关的暴力和袭击的受害者，他们的健康和职业前途都因酗酒而受到威胁。本研究将致力于以下目标：1)开发一种以理论为导向的四期、基于网络的量身定制的简短动机干预，以预防/减少未成年大学新生（即18至20岁）的ARD。从密歇根大学新生班级中招募并随机分配研究参与者，在一个学年的前两个月进行量身定制的简短干预（TBI）或仅网络调查（WSO）条件。两种情况下的参与者都将被问及相同的基线、定制和随访问题，并将访问研究网站的次数相同，但只有TBI组将接受定制的干预课程。TBI信息将根据每个TBI小组成员的人口统计、ARD水平和行为变化特征进行定制，并且在四次会议期间，将根据需要测量制定干预信息所需的定制信息。两组将在6个月、12个月和18个月时进行简短的网络调查。2)通过比较TBI组和WSO组在基线、干预后6个月、12个月和18个月的ARD结果，评估基于网络的TBI减少ARD的疗效。最终的样本量计划为540人。将测试干预的主要效果和与性的相互作用。3)确定在网络上完成1、2、3和4次干预/控制会话的参与者的基线ARD行为和态度；并完成6、12、18个月的随访。这项研究将检查参与和辍学的预测因素。如果有效，建议的干预措施可以进行低成本的修改，以向大量大学生和其他人群提供有效的干预措施，并针对其他健康风险行为。

DESCRIPTION (provided by applicant): Great need is evident for effective interventions to prevent/reduce at-risk drinking (ARD; combinations of quantity and frequency that place one's health at risk) among underage college undergraduate students. Currently in the United States an average of three college students die each day in alcohol-related car crashes, while thousands more are victims of alcohol-related violence and assault, and risk their health and professional futures through ARD. This study will address the following Aims. 1) Develop a theory-directed four-session, web-based tailored brief motivational intervention to prevent/reduce ARD among underage freshmen college students (i.e., aged 18 through 20 years). Recruitment and random assignment of study participants from the University of Michigan freshmen class to either a Tailored Brief Intervention (TBI) or web survey only (WSO) condition will occur in the first two months of one academic year. Participants in both conditions will be asked the same baseline, tailoring and follow-up questions and will visit the study website the same number of times, but only the TBI group will receive the tailored intervention sessions. TBI messages will be tailored on each TBI group member's demographics, ARD level, and behavior change characteristics, and tailoring information needed to formulate the intervention messages will be measured as needed during the four sessions. Both groups will be followed-up with a brief Web-based survey at six, 12, and 18 months. 2) Evaluate the efficacy of the web-based TBI to reduce ARD by comparing the TBI and WSO groups on ARD outcomes at baseline, six, 12, and 18 months post intervention. The final sample size is planned to be 540. Intervention main effects and interactions with sex will be tested. 3) Identify the baseline ARD behaviors and attitudes of participants who: complete 1, 2, 3, and four intervention/control sessions on the Web; and complete the 6-, 12-, and 18-month follow-ups. The study will examine predictors of participation and dropout. If effective, the proposed intervention could be inexpensively modified to deliver effective interventions to large numbers of university students, members of other populations, and to target other health risk behaviors.
