Implementing Web-Based SBI for Marijuana Use in College Student Health Centers

描述（由申请人提供）：吸食大麻对大学生的健康和幸福有重大风险。使用大麻的学生更有可能经历各种影响他们学习成绩、身体健康和人际关系的后果。尽管有有效的干预措施，很少有学生认为他们的大麻使用是有问题的，更不用说寻求治疗来减少他们的使用。卫生技术的发展大大扩大了让学生参与筛查和提供干预措施的潜在方法范围。特别是，现在已经开发了基于网络的方法，它提供了一个机会，以一种易于使用和保密的方式筛选和向学生提供关于大麻使用的个性化反馈。这些方法在理论上是有充分依据的，现在在许多大学都可以使用。然而，关于其有效性或最佳传播策略的实证研究很少。拟议的R34可行性/试点项目旨在提供初步数据，说明一种高度利用的基于网络的筛选和简短干预方法的有效性，以减少到大学健康中心就诊的学生使用大麻的情况和后果。学生健康服务代表了一个机会主义的背景下，筛选和提供简短的干预大麻使用的大部分人口。该项目的主要目标是：1)确定实施计算机筛选和基于网络的干预方法的可行性，以解决在这种情况下学生使用大麻的问题；2)进行试点试验，以估计该方法在减少大麻使用和后果方面的效应大小。到大学卫生保健诊所就诊的本科生将被邀请参加一项健康行为研究。那些通过筛选被确定为当前大麻使用者的人将被随机分配接受一个广泛使用的基于网络的干预程序[e-Toke]或一个控制条件。这种干预对大麻使用天数和大麻相关后果的影响将在3个月和6个月时进行检查。这项工作的结果将为一项大规模的随机对照试验提供基础，以检验这种方法在减少参加大学保健服务的学生使用大麻及其相关后果方面的有效性。

DESCRIPTION (provided by applicant): Marijuana use is a significant risk to health and well-being for university students. Students who use marijuana have an increased likelihood of experiencing a variety of consequences that impact their academic performance, physical health, and relationships. Despite the availability of efficacious interventions, few students identify their marijuana use as problematic let alone seek treatment to reduce their use. Developments in health technology have greatly expanded the potential range of methods to engage students in screening and deliver interventions. In particular, web-based approaches have now been developed which provide an opportunity to screen and deliver personalized feedback to students about their marijuana use in an easily utilized and confidential manner. These approaches are theoretically well grounded and are now available at many universities. However, there has been little empirical research on their efficacy or on optimal strategies for dissemination. The proposed R34 feasibility/pilot project seeks to provide preliminary data on the efficacy of a highly utilized, web-based screening and brief intervention approach for reducing marijuana use and consequences among students presenting to a university health center. Student health services represent an opportunistic context to screen and deliver brief intervention for marijuana use to large segments of the population. The primary goals of this project are to: 1) determine the feasibility of implementing a computerized screening and web-based intervention approach to address marijuana use among students in this setting, and 2) conduct a pilot trial to estimate the effect size of this approach for reducing marijuana use and consequences. Undergraduate students who present to a university health care clinic will be invited to participate in a study of health behaviors. Those identified as current marijuana users through screening will be randomly assigned to receive a widely used web-based intervention program [e-Toke] or a control condition. The effect of this intervention on days of marijuana use and marijuana-related consequences will be examined at three and six months. Results of this work will provide the basis for a large scale randomized controlled trial to examine the efficacy of this approach for reducing marijuana use and related consequences among students attending university health care services. PUBLIC HEALTH RELEVANCE: This research seeks to improve the efficacy and effectiveness of screening and brief intervention approaches designed to reduce marijuana use and minimize marijuana-related harm among university students.
