Communication Messages to Reduce Youth Multiple Tobacco Product Use

项目摘要/摘要 烟草使用仍然是美国可预防的死亡的主要原因。近50%的年轻人 烟草使用者现在同时使用两种或两种以上烟草产品--定义为多种烟草产品 (MTP)使用。青少年服用MTP令人担忧，因为它与尼古丁的两倍增加有关 依赖症状，成功戒烟的可能性降低，以及使用其他物质的风险增加 和心理健康问题。存在许多交流信息，以警告年轻人特定的 烟草产品，如电子烟或香烟。然而，几乎所有的烟草通讯信息 一次只关注一种烟草产品，这可能会导致MTP用户消费 不是消息的目标。此外，这些通信消息可能不能很好地与MTP一起工作 吸烟者比单一吸烟者更有可能低估烟草的危害， 依赖尼古丁，社会经济地位(SES)较低。建议的总体目标是 K01项目是开发和评估有关使用MTP的危害的信息。主要的假设是 与现有的消息相比，MTP消息将更多地增加戒烟意图 只关注单一烟草产品和控制信息。次要目标是确定 MTP使用风险较高的青少年，特别是SES较低的青少年中的信息。在目标1中，我将确定 有效的主题为面向青年的信息，传达使用MTP的危害。在《目标2》中，我会 制定一套高影响力的信息，劝阻年轻人使用MTP，并确定其他 信息要素(例如，证明、戒烟方法、自我效能提示)会增加戒烟意向 对年轻的MTP用户进行离散选择实验(DCE)。最后，在目标3中，我将进行三臂 对青年MTP用户(SES降低50%)进行试点随机对照试验(RCT)，以查看MTP消息 在两周内以短信形式发送的戒烟意向比现有的更多 只关注单一烟草产品的信息和控制信息。这项研究将使 为制定烟草控制宣传战略作出了重大和及时的贡献 并对FDA对通信研究的兴趣做出回应。我的长期职业目标是 开展独立研究，重点是通过健康预防和减少青少年烟草使用 沟通干预。这个职业发展奖将帮助我通过提供新的 A)健康传播理论和信息开发方面的培训，b)健康实验设计 传播研究，包括设计离散选择实验，以及c)电子健康干预 青春年华。我的培训计划包括与我的指导团队一起当学徒，正式的课程学习，实践 研究活动和研讨会。这项奖励最终将以R01申请全面RCT测试而告终 MTP消息对青少年MTP用户戒烟尝试和其他行为结果的有效性。

PROJECT SUMMARY/ABSTRACT Tobacco use remains the leading cause of preventable death in the United States. Almost 50% of youth tobacco users now concurrently use two or more tobacco products—defined as multiple tobacco product (MTP) use. Youth MTP use is concerning because it associated with a two-fold increase in nicotine dependence symptoms, decreased likelihood of successful quitting, and increased risk of other substance use and mental health problems. Many communication messages exist to warn youth of the harms of specific tobacco products, like e-cigarettes or cigarettes. However, almost all tobacco communication messages focus on one tobacco product at a time, which could lead MTP users to consume the tobacco product that is not the target of the messages. Moreover, these communication messages may not work well with MTP users who are more likely than single tobacco users to underestimate the harms of tobacco, be more dependent on nicotine, and be of lower socioeconomic status (SES). The overarching goal of the proposed K01 project is to develop and evaluate messages about the harms of MTP use. The primary hypothesis is that MTP messages will increase intentions to quit using all tobacco products more than existing messages that focus only on single tobacco products and control messages. A secondary goal is to determine the impact of messages among youth at higher risk of MTP use, specifically youth of lower SES. In Aim 1, I will identify effective themes for youth-oriented messages that communicate the harms of MTP use. In Aim 2, I will develop a set of high impact messages that discourages MTP use among youth and determine whether other message elements (e.g., testimonials, quitting approach, self-efficacy cue) increase tobacco quit intentions using a discrete choice experiment (DCE) with youth MTP users. Finally, in Aim 3, I will conduct a three-arm pilot randomized controlled trial (RCT) with youth MTP users (50% lower SES) to see if the MTP messages delivered as text messages over a two-week period increase tobacco quit intentions more than existing messages that focus only on single tobacco products and control messages. This research would make significant and timely contributions to the development of tobacco control communication strategies in the United States and is responsive to FDA’s interest in communications research. My long-term career goal is to conduct independent research that focuses on preventing and reducing youth tobacco use through health communication interventions. This career development award will help me reach this goal by providing new training in a) health communication theory and message development, b) experimental design for health communication research, including design of discrete choice experiments, and c) eHealth interventions for youth. My training plan includes apprenticeships with my mentorship team, formal coursework, hands-on research activities, and workshops. This award will culminate in a R01 application for a full-scale RCT testing the effectiveness of MTP messages on quit attempts and other behavioral outcomes among youth MTP users.
