Optimizing risk messages to promote waterpipe tobacco cessation in young adults

项目摘要 水烟是美国年轻人最常用的烟草产品之一。水管 烟草使使用者暴露于高水平的致癌物质和其他有害有毒物质，可导致长期 成瘾，并与癌症和其他负面健康结果有关。尽管有这些证据， 成年人并不认为水烟有害或上瘾，这种信念代表了驱使人们吸烟的独特动机。 水管使用率很高。水烟干预研究的重点是临床戒烟 对老年依赖者的干预。这些干预措施对年轻人的影响可能有限 成年人，因为他们对临床戒烟干预的使用率很低，他们不认为自己处于 需要这样的支持。我们的研究表明，传播危害的公共卫生信息， 水烟的成瘾性可以改变年轻成年水烟使用者的感知和动机 停止这项研究建立在我们的初步工作，并解决了在这一研究领域的关键差距， 调整已经成功解决吸烟问题的信息传递策略， 对年轻人使用水烟的影响。我们将严格检查信息传达的效果 使用文本和视觉图像并通过移动的电话传递水烟的危害和成瘾性 在使用水烟的18至30岁的年轻人中使用多媒体信息服务（MMS）。我们 一种方法利用在线众包进行消息细化，并利用交互式移动的技术 与参与者一起发送MMS消息，并测试个人定制的MMS内容的附加效果。 参与者将完成基线测量，接收有关危害和成瘾性的基本信息， 水烟斗烟草，并随机分为三个条件：1）对照条件，不接受额外的 消息传送，2）非定制MMS条件，或3）定制MMS条件。在1个月内，那些被分配到 彩信条件将收到短信提示每周两天交付到他们的移动的手机通过 一个交互式信息系统，以评估水烟的看法和行为。在回应 提示，参加者将收到有关水烟的危害和成瘾性的彩信。为 量身定制的彩信条件下，消息内容将个性化响应基线措施， 在干预期间通过交互式文本消息交换动态地进行。水烟 将在基线后1个月、3个月和6个月重新评估使用和假设的介质。我们的研究将 生成有关移动的MMS和定制MMS消息内容的影响的急需数据， 水烟使用干预措施。我们的研究直接涉及国家癌症研究所烟草控制 研究优先事项和研究结果可以转化为NCI，食品和 药品管理局对公众进行关于水烟危害的教育，以及其他有针对性的干预措施。

Project Summary Waterpipe tobacco is one of the most commonly used tobacco products among U.S. young adults. Waterpipe tobacco exposes users to high levels of carcinogens and other harmful toxicants, can lead to long-term addiction, and is associated with cancer and other negative health outcomes. Despite this evidence, young adults do not view waterpipe tobacco as harmful or addictive, beliefs representing unique motives that drive the high prevalence of waterpipe use. Waterpipe tobacco intervention research has focused on clinical cessation interventions among older, dependent users. These interventions likely have limited impact among young adults because their use of clinical cessation interventions is low and they do not view themselves to be in need of such cessation supports. Our research indicates public health messages conveying harms and addictiveness of waterpipe tobacco can shift young adult waterpipe tobacco users' perceptions and motivate cessation. This study builds from our preliminary work and addresses a critical gap in this research area by adapting messaging strategies that have been successful for addressing cigarette smoking to optimize their impact on young adults' waterpipe tobacco use. We will rigorously examine the effects of messages conveying harms and addictiveness of waterpipe tobacco using text and visual imagery and delivered by mobile phone multimedia messaging service (MMS) among young adults ages 18 to 30 who use waterpipe tobacco. Our approach leverages online crowdsourcing for message refinement and interactive mobile technology to engage with participants, deliver MMS messages, and test added effects of personally tailored MMS content. Participants will complete baseline measures, receive basic messages on harms and addictiveness of waterpipe tobacco, and be randomized to three conditions: 1) a control condition receiving no additional messaging, 2) an untailored MMS condition, or 3) a tailored MMS condition. For 1-month, those assigned to MMS conditions will receive text message prompts on two days each week delivered to their mobile phones via an interactive messaging system to assess waterpipe tobacco perceptions and behavior. After responding to prompts, participants will receive MMS messages on harms and addictiveness of waterpipe tobacco. For the tailored MMS condition, message content will be personalized to responses to baseline measures and dynamically through the interactive text message exchanges during the intervention period. Waterpipe tobacco use and hypothesized mediators will be reassessed 1-, 3-, and 6-months post-baseline. Our study will generate critically needed data on the effects of mobile MMS and tailored MMS message content to inform waterpipe tobacco use interventions. Our study directly addresses National Cancer Institute tobacco control research priorities and the findings can be translated to population intervention efforts by the NCI, Food and Drug Administration public education about the harms of waterpipe tobacco, and other targeted interventions.
