Communication Messages to Reduce Youth Multiple Tobacco Product Use

项目总结/摘要 烟草使用仍然是美国可预防死亡的主要原因。近50%的年轻人 烟草使用者现在同时使用两种或更多种烟草产品-定义为多种烟草产品 (MTP)使用.青少年使用MTP令人担忧，因为它与尼古丁增加两倍有关 依赖症状，成功戒烟的可能性降低，使用其他物质的风险增加 和心理健康问题。许多通信信息存在警告青年的危害， 烟草产品，如电子烟或香烟。然而，几乎所有的烟草通信信息 一次专注于一种烟草产品，这可能导致MTP使用者消费 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 吸烟者比单一烟草使用者更有可能低估烟草的危害， 依赖尼古丁，社会经济地位较低（SES）。拟议的总体目标 K 01项目旨在开发和评估有关MTP使用危害的信息。主要假设是， 与现有的信息相比，中期计划信息将更多地增加人们戒掉所有烟草产品的意愿， 只注重单一烟草产品和控制信息。第二个目标是确定 在使用MTP风险较高的青年中，特别是社会经济地位较低的青年中，在目标1中，我将确定 有效的主题，以青年为导向的信息，沟通使用MTP的危害。在目标2中，我将 制定一套影响力大的信息，劝阻青年人使用中期计划，并确定其他 消息元素（例如，推荐、戒烟方法、自我效能线索）增加戒烟意愿 使用离散选择实验（DCE）与青年MTP用户。最后，在目标3中，我将进行三臂 在青年MTP使用者（SES降低50%）中进行的试点随机对照试验（RCT），以观察MTP信息是否 在两周的时间内，通过短信传递的信息比现有的信息更能增加戒烟意愿。 仅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重大和及时的贡献， 美国，并响应FDA对通信研究的兴趣。我的长期职业目标是 开展独立研究，重点关注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实现这一目标， a）健康传播理论和信息开发培训，B）健康实验设计 通信研究，包括离散选择实验的设计，以及c）电子卫生干预措施， 青年我的培训计划包括与我的导师团队一起实习，正式课程，动手实践 研究活动和研讨会。该奖项将最终在R 01应用程序的全面RCT测试 MTP信息对青年MTP使用者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.
