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烟草或无烟烟草（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，即向服务不足的用户群体提供戒烟服务，并重新关注评估针对年轻人的新的和创新的戒烟方案。鉴于青少年是互联网的重度使用者，并且有迹象表明基于网络的干预措施对其他健康行为有所帮助，我们建议开发并测试针对青少年的基于互联网的ST戒烟计划的有效性。这项建议的两组随机对照试验将比较一个有针对性的、量身定制的、高度互动的ST戒烟网站与一个提供中等熟练的互联网搜索用户可以找到的信息的对照网站的疗效。干预的核心特征包括：a)针对青少年性传播技术使用者；B)根据参与者与项目的持续互动定制内容；c)个性化、动态地展示ST停止工具、维护资源和信息；d)在网络论坛上监测在线点对点和专家对参与者的性传播疾病戒烟支持。对照组的参与者将接触到一个更静态的信息网站，其中包含ST戒烟内容，并附有注释链接，链接到互联网上仅提供信息的ST资源。一项多方面的计划将招募1550名年龄在14-18岁之间的参与者，该计划既针对参与者，也针对可以推荐他们的人。主要结果是在入组后6周和7.5个月戒烟，在定制的、有针对性的互动条件下，青少年的戒烟率预计会更高。我们还将调查基线受试者特征、项目参与和过程变量作为戒烟结果的预测：成本分析将确定两种情况的每次戒烟成本和相对成本效益。拟议的基于互联网的青少年烟草戒烟计划的公共卫生潜力是巨大的。相关性：为服务不足的青少年无烟烟草使用者提供网络戒烟计划的经验评估是有根据和及时的。鉴于绝大多数成年烟草使用者在18岁之前开始使用烟草，而青少年烟草使用者可获得的戒烟资源很少，利用互联网帮助年轻烟草使用者在成瘾过程的早期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.
