QuitSpit: An Internet-Based Smokeless Tobacco Cessation Program for Teens

描述（由申请人提供）：许多美国青少年习惯性地使用咀嚼或无烟烟草（ST），并希望戒烟，但缺乏资源。该项目符合国家癌症研究所的目标，即为服务不足的用户群体提供戒烟服务，并重新关注对年轻人新的和创新的戒烟计划的评估。鉴于青少年是互联网的重度用户，并且有迹象表明，基于网络的其他健康行为干预措施是有帮助的，我们建议开发和测试针对青少年的基于互联网的ST停止计划的有效性。这项拟议的两组随机对照试验将比较有针对性的、定制的、高度互动的ST段抬高终止网站与对照网站的疗效，对照网站提供的信息是中等熟练的互联网搜索用户可以找到的。干预的核心特征包括：a）针对青少年ST使用者; B）基于参与者与计划的持续互动定制内容; c）个性化、动态呈现ST停止工具、维护资源和信息; d）在网络论坛中监测在线点对点和专家对参与者ST停止支持。在控制条件下的参与者将接触到一个更静态的信息网站，包含ST停止的内容，与注释链接到信息只有ST资源在互联网上。一个多方面的计划，针对与会者和人谁可以介绍他们将被用来招募1,550名参与者年龄在14-18岁。主要结果是在登记后6周和7.5个月戒烟，在定制的有针对性的互动条件下登记的青少年戒烟率预计会更高。我们还将调查基线受试者特征，计划参与和过程变量作为戒烟结果的预测：成本分析将确定每次戒烟的成本和两种情况的相对成本效益。针对青少年ST使用者的拟议的基于互联网的戒烟计划的公共卫生潜力是巨大的。相关性：对网络提供的戒烟计划进行实证评估，以帮助这些服务不足的青少年无烟烟草使用者，这是必要的，也是及时的。鉴于绝大多数成年烟草使用者在18岁之前就开始使用烟草，而青少年烟草使用者几乎没有戒烟资源，利用互联网帮助年轻的ST使用者在成瘾过程中尽早戒烟具有巨大的公共卫生潜力。

DESCRIPTION (provided by applicant): Many American teens engage in the habitual use of chewing or smokeless tobacco (ST) and wish to quit but lack resources. This project meets the goals of the National Cancer Institute for providing tobacco cessation services to underserved populations of users and the renewed focus on evaluation of new and innovative cessation programs for young people. Given that teens are heavy users of the Internet and there are promising signs that web-based interventions for other health behaviors have been helpful, we propose to develop and test the effectiveness of an Internet-based ST cessation program targeted to teens. This proposed two-arm randomized control trial will compare the efficacy of a targeted, tailored, and highly interactive ST cessation website to a control website that presents information that the moderately skillful Internet search user could locate. The core features of the intervention include: a) targeted to teen ST users; b) tailored content based on ongoing participant interaction with the program; c) personalized, dynamic presentation of ST cessation tools, maintenance resources, and information; and d) monitored online peer-to-peer and expert-to-participant ST cessation support in a web forum. Participants in the control condition will be exposed to a more static informational website containing ST cessation content, with annotated links to information-only ST resources on the Internet. A multifaceted plan-aimed both attendees and persons who could refer them-will be used to recruit 1,550 participants ages 14-18. The primary outcomes are tobacco cessation at 6 weeks and 7.5 months post-enrollment, with quit rates expected to be higher in teens enrolled in the tailored, targeted interactive condition. We will also investigate baseline subject characteristics, program engagement, and process variables as predictive of cessation outcomes: A cost analysis will determine the cost per quit and relative cost-effectiveness of the two conditions. The public health potential of the proposed Internet-based tobacco cessation program for teen ST users is great. Relevance: An empirical evaluation of an web delivered cessation program for this underserved teen audience of smokeless tobacco users is both warranted and timely. Given that a vast majority of adult tobacco users started their use before age 18, and there are few cessation resources available to teen tobacco users, there is great public health potential in using the Internet to assist young ST users in quitting early in their addiction process.
