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地说，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，该计划使用当代计算机游戏技术，通过学校内部网（即，连接到学校服务器的联网计算机）。由于这是一个雄心勃勃的目标，我们建议分两个阶段进行。在这里，我们建议制定和审查这一计划的可行性。如果我们成功了，在第二阶段，我们将进行随机试验，以评估该计划的长期有效性。计划的组成部分将针对来自社会认知理论和风险感知理论的经验支持的调解机制。这些调解机制致力于实现以下教育目标：（1）增加对烟草使用的负面影响和减少对烟草使用的正面影响，（2）改变态度的认知方面，（3）减少关于烟草使用的主观规范，（4）增加感知的行为控制，（5）改变感知的烟草使用风险（增加成瘾的感知风险，增加对累积后果的感知，减少乐观偏见）。计划中的方案包括至少13个有效的组成部分，在五年级的八个会议上交付，教师的指导指南，以配合该方案和一系列的通讯，将邮寄给家长。将使用形成性定性评价迭代开发计划组成部分，并对每个组成部分的有效性进行定量评价。我们建议在两所小学进行可行性研究，以检查教师和学生的满意度，计划的实施和学生的参与。拟议的计算机为基础的程序将是互动和参与，将尽量减少对教师的要求，将促进保真度的实施，并有可能为量身定制。该计划的内联网交付允许有关汇总同学的烟草使用和态度的反馈，努力改变学生的看法规范使用和态度。

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.
