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 烟草使使用者暴露在高水平的致癌物质和其他有害毒物中，可导致长期 上瘾，并与癌症和其他负面健康后果有关。尽管有这些证据，杨 成年人并不认为水烟有害或令人上瘾，这一信念代表了推动 自来水管道使用率很高。水烟干预研究的重点是临床戒烟 在依赖的老年用户中进行干预。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，而且他们不认为自己处于 需要这样的停机支持。我们的研究表明，公共卫生信息传达的危害和 水烟成瘾可以改变青壮年水烟使用者的认知和动机 停止。这项研究建立在我们的初步工作基础上，并通过以下方式解决了这一研究领域的一个关键差距 调整在解决吸烟问题上取得成功的消息策略，以优化其 对年轻人使用水烟的影响。我们将严格审查信息传递的效果 利用文字和视觉图像通过手机传递水烟的危害和成瘾性 彩信服务(MMS)在18至30岁使用水烟的年轻人中使用。我们的 方法利用在线众包来完善消息和互动移动技术，以参与 与参与者一起发送彩信，并测试个人定制彩信内容的附加效果。 参与者将完成基线测量，收到有关危害和成瘾性的基本信息 水烟，并随机分为三种情况：1)对照条件 消息，2)未定制的MMS条件，或3)定制的MMS条件。对于1个月，分配给 彩信条件将每周两天收到短信提示，通过以下方式发送到其手机 一种用于评估水烟感知和行为的交互式消息系统。在回应后 在提示下，参与者将收到关于水烟的危害和成瘾的彩信。对于 定制彩信条件、消息内容将个性化以响应基线测量和 在干预期间动态地通过交互文本消息交换。水烟烟叶 使用和假设的调解人将在基线后1个月、3个月和6个月重新评估。我们的研究将 生成关于移动彩信影响的迫切需要的数据和定制的彩信内容以供 水烟使用干预措施。我们的研究直接针对国家癌症研究所烟草控制 研究的重点和结果可以转化为NCI、Food和 药品监督管理局对公众进行有关水烟危害的教育，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.
