Intranet-based Tobacco Prevention Program for Children

描述（由申请人提供）：这项研究的长期目标是：具体来说，我们计划开发一个令人兴奋和迷人的基于计算机的烟草预防计划，该计划使用现代计算机游戏技术，通过基于学校的内部网（即，连接到学校服务器的网络计算机）交付。由于这是一个雄心勃勃的目标，我们建议分两阶段实施。在此，我们建议开发并检验该计划的可行性。如果我们成功了，在第二阶段，我们将进行随机试验来评估该计划的长期有效性。项目组成部分将针对来自社会认知理论和风险感知理论的实证支持的中介机制。这些中介机制解决了以下教育目标：(1)增加对烟草使用的负面影响，减少对烟草使用的积极影响；(2)改变态度的认知方面；(3)减少对烟草使用的主观规范；(4)增加感知到的行为控制；(5)改变感知到的烟草使用风险（增加感知到的成瘾风险，增加感知到的累积后果，减少乐观偏见）。计划中的课程包括至少13个有效的组成部分，在五年级的八堂课中进行，一份教师的教学指南伴随着课程，以及一系列将邮寄给家长的新闻通讯。程序组件将使用形成性定性评估迭代开发，每个组件的有效性将进行定量评估。我们建议在两所小学进行可行性研究，以考察教师和学生的满意度，计划的实施和学生的参与。拟议的基于计算机的课程将具有互动性和吸引力，将最大限度地减少对教师的要求，将促进实施的保真性，并具有定制的潜力。该计划的内联网交付允许对全班同学的烟草使用和态度进行反馈，以努力改变学生对规范使用和态度的看法。

DESCRIPTION (provided by applicant): The long-term goal of this research is to Specifically, we plan to develop an exciting and captivating computer-based tobacco prevention program that uses contemporary computer game techniques delivered over a school-based intranet (i.e., networked computers linked to a school-based server). Since this is an ambitious goal, we are proposing a two-phase approach. Here, we propose to develop and examine the feasibility of this program. If we are successful, in a second phase, we will conduct a randomized trial to evaluate the long-term effectiveness of the program. Program components will target empirically supported mediating mechanisms derived from social cognitive theories and risk perception theory. These mediating mechanisms address the following educational objectives: (1) increasing negative and decreasing positive affect towards tobacco use, (2) changing cognitive aspects of attitudes, (3) decreasing subjective norms regarding tobacco use, (4) increasing perceived behavioral control, and (5) changing perceived risks of tobacco use (increasing the perceived risk of addiction, increasing perception of cumulative consequences, and decreasing optimism bias). The planned program consists of a minimum of 13 effective components delivered over eight sessions in 5th grade, a teacher's instructional guide to accompany the program and a series of newsletters that will be mailed to parents. Program components will be developed iteratively using formative qualitative evaluation and the effectiveness of each component will be evaluated quantitatively. We propose to conduct a feasibility study in two elementary schools to examine teacher and student satisfaction, program implementation and participation by students. The proposed computer-based program will be interactive and engaging, will minimize demands on teachers, will facilitate fidelity of implementation, and has the potential for tailoring. Intranet delivery of the program allows for feedback regarding aggregated classmates' tobacco use and attitude in an effort to change student's perception of normative use and attitude.
