Evaluation of an Intranet-Based Alcohol Prevention Program in Middle School

描述（由申请人提供）：本研究的目的是创建和评估一个有效的、令人兴奋的、可传播的基于计算机的预防程序，点击城市(c)：酒精，供七年级和八年级学生使用。Click City(c)：酒精的最终目标是防止在高中和高中后开始大量饮酒。这个计划在其交付系统和开发过程中都是独一无二的。该项目将通过校园网（即与校园网服务器相连的联网计算机）进行，用户可以单独与项目互动，并通过收到同学的即时反馈来分享他们的经验。该计划的各个组成部分将被迭代开发和经验评估，以确保它们在改变基于理论的病因机制方面是有效的。组件开发由焦点小组组成，然后是用户小组，最后是经验评估。我们计划在研究的前两年开发和测试大约24个组件（目标1）。最后的点击城市(c)：酒精项目将包括12个有效的组成部分，在七年级的三周时间内分六次进行。接下来是两次强化课程，共包括5个部分，在八年级的一周时间内交付。(目标2)。该计划将向家长和教师指南发送教育通讯。在发展之后，我们将进行一项群体随机试验，以评估该计划与学校通常的酒精预防课程相比的功效（目标3）。我们计划招募，分层和随机分配26所中学，按两个条件之一，点击城市(c)：酒精和常规课程（UC）。Click City的学生(c)：在7年级课程开始之前，在7年级课程开始之后，在8年级强化课程开始之后，在7年级课程开始之后，在8年级课程开始大约一年后，在9年级进行后续评估，以评估长期结果，在8年级评估之后一年。主要的结果将是九年级的酗酒。次要短期（小学八年级）和长期（九年级）结果将是酒精使用的程度以及将来大量饮酒的意愿和意图。

DESCRIPTION (provided by applicant): The purpose of this research is to create and evaluate an effective, exciting, and disseminable computer- based prevention program, Click City(c): Alcohol, for use by 7th and 8th grade students. The ultimate goal of Click City(c): Alcohol is to prevent the onset of heavy drinking during high school and post-high school. This proposed program is unique both in its delivery system and the development process. The program will be delivered over a school-based intranet (i.e., networked computers linked to a school-based server), which enables users to interact individually with the program and to share their experiences by receiving immediate feedback on their classmates' responses. Individual components of the program will be iteratively developed and empirically evaluated to assure that they are effective at changing theoretically based etiological mechanisms. Component development consists of focus groups, followed by user groups, and culminates in an empirical evaluation. We plan to develop and test approximately 24 components over the first two years of the study (Aim 1). The final Click City(c): Alcohol program will consist of 12 effective components delivered in six sessions over a three-week period in 7th grade. This is followed by two booster sessions, consisting of a total of 5 components delivered over a one-week period in 8th grade. (Aim 2). Educational newsletters to parents and teacher guides will accompany the program. Following development, we will conduct a group randomized trial to evaluate the efficacy of this program as compared to schools' usual alcohol prevention curriculum (Aim 3). We plan to recruit, stratify and randomly assign 26 middle schools to one of the two conditions, Click City(c): Alcohol and Usual Curriculum (UC). Students in the Click City(c): Alcohol and yoked UC schools will be assessed prior to the beginning of the 7th grade program, following the 7th grade program, following the 8th grade booster, which would occur approximately one year after the 7th grade program, and a follow-up assessment in the 9th grade to assess long-term outcomes, one year after the 8th grade assessment. The primary outcome will be heavy drinking in the 9th grade. Secondary short term (post, 8th grade) and long term (9th grade) outcomes will be extent of alcohol use and willingness and intention to engage in heavy drinking in the future. PUBLIC HEALTH RELEVANCE: There is a substantial increase in heavy drinking among students between middle school (grades 7 and 8) and high school (grades 9 through 12). Heavy drinking in adolescence is associated with significant physical and neurological consequences. We propose to develop and evaluate a computer-based program, implemented as part of the middle school curriculum, to prevent heavy drinking in high school. There is a substantial increase in heavy drinking among students between middle school (grades 7 and 8) and high school (grades 9 through 12). Heavy drinking in adolescence and emerging adulthood is associated with serious consequences, including drinking while driving, unwanted sexual behavior and assault, as well as neurological impairment. Age of onset of heavy drinking is predictive of subsequent abuse. The purpose of Click City(c): Alcohol, which translates contemporary theories regarding engaging in health-risk behaviors into practice, is to prevent heavy drinking, which will ultimately impact the health and safety of youth.
