Young adults who never engaged in waterpipe tobacco smoking (WTS) yet are open to trying it, that is, are susceptible, is a high-risk group for initiation WTS. Very few interventions dissuade this group from WTS. Thus, we explored how four short videos that varied themes of WTS harms influenced susceptible young adults' risk perceptions, risk beliefs, and susceptibility to future WTS. As part of online cross-sectional study, 208 participants aged 18-34 were randomized to watch or not a short video; each video focused on different themes of WTS risks: physical harms, myths about WTS, addiction, and harms to others. The main outcomes were perceived personal risks, risk beliefs, perceived harm of WTS compared to cigarettes, and susceptibility to future WTS. Watching any video increased beliefs of harm of WTS and lowered susceptibility to future WTS compared to not watching a video. The theme of physical harms was most effective at increasing risk beliefs and lowering susceptibility to future WTS. All four videos were rated as credible, engaging, personally relevant, producing negative affect toward WTS, and effective at dissuading WTS. These promising findings suggest further testing is needed to determine if effects persist and prevent WTS among adults susceptible to WTS.
从未接触过水烟烟草（WTS）但愿意尝试的年轻人，即易感性群体，是开始接触 WTS 的高风险群体。很少有干预措施能劝阻这一群体接触 WTS。因此，我们探讨了四个主题不同的 WTS 危害短视频如何影响易感性的年轻成年人对未来 WTS 的风险认知、风险信念和易感性。作为在线横断面研究的一部分，208 名年龄在 18-34 岁的参与者被随机分配观看或不观看短视频；每个视频都聚焦于 WTS 危害的不同主题：身体危害、WTS 危害的误解、成瘾和对他人的危害。主要结果是感知到的个人风险、风险信念、对 WTS 相对于香烟的危害的感知以及未来接触 WTS 的易感性。与不观看视频相比，观看任何视频都增加了对 WTS 危害的信念，并降低了未来接触 WTS 的易感性。身体危害主题最有效地增加了风险信念并降低了未来接触 WTS 的易感性。四个视频都被评为可信、引人入胜、与个人相关、对 WTS 产生负面情绪以及有效地劝阻 WTS。这些有希望的发现表明，需要进一步测试以确定效果是否持久并防止易感性成年人接触 WTS。
