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

描述(由申请人提供)：这项研究的目的是创建和评估一个有效的、令人兴奋的和可传播的基于计算机的预防计划，Click City(C)：酒精，供7年级和8年级的学生使用。Click City(C)的最终目标：酒精是为了防止在高中和高中后大量饮酒。这一拟议的计划在其交付系统和开发过程中都是独一无二的。该计划将通过学校内联网(即连接到学校服务器的联网计算机)提供，使用户能够单独与该计划互动，并通过接收对同学反应的即时反馈来分享他们的经验。该计划的各个组成部分将进行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，紧随其后的是用户组，最后是经验评估。我们计划在研究的头两年开发和测试大约24个组件(目标1)。最后的Click City(C)：酒精课程将由12个有效成分组成，在七年级为期三周的六个课程中提供。之后是两次强化课程，包括在八年级为期一周的时间内提供的总共5个组件。(目标2)。针对家长和教师指南的教育通讯将伴随着该节目。随后，我们将进行一项团体随机试验，以评估该计划与学校通常的酒精预防课程(目标3)的效果。我们计划对26所中学进行招募、分层并随机分配到两个条件之一：点击城市(C)：酒精和普通课程(UC)。Click City(C)：加州大学酒精与偏执学校的学生将在7年级课程开始之前、7年级课程之后、8年级强化课程之后进行评估，这将在7年级课程后大约一年进行，并在9年级时进行后续评估，以评估长期结果，8年级评估后一年。主要结果将是在9年级大量饮酒。次要的短期(8年级后)和长期(9年级)结果将是酒精使用的程度以及未来大量饮酒的意愿和意图。 与公共健康相关：在初中(7年级和8年级)和高中(9年级到12年级)之间的学生中，酗酒的人数大幅增加。青春期大量饮酒与严重的身体和神经后果有关。我们建议开发和评估一个基于计算机的程序，作为中学课程的一部分，以防止高中过度饮酒。 在初中(7年级和8年级)和高中(9年级到12年级)之间的学生中，酗酒的人数大幅增加。在青春期和成年初期大量饮酒与严重的后果有关，包括开车时饮酒、不受欢迎的性行为和攻击，以及神经功能障碍。开始大量饮酒的年龄预示着随后的虐待行为。Click City(C)：酒精，将当代关于从事危害健康的行为的理论转化为实践，其目的是防止酗酒，这最终将影响年轻人的健康和安全。

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.
