Measure the impact of brief, academic-led, evidence-based social media videos on vaping harm perceptions among young adults.
On-line between-subjects experimental study. Participants were randomized to one of two conditions: experimental (exposed to one of eight brief videos, designed for social media, with academic experts addressing vaping harms) or control. Before and after exposure to the videos, all participants answered questions about their perceptions of vaping and smoking and socio-demographics.
Qualtrics on-line survey platform.
593 young adults aged 18-30 years who resided in the UK (49.7% female, 49.2% male; 8.9% exclusively smoked, 32% exclusively vaped, 28.7% did both and 30.4% did neither). Participants were randomly assigned to intervention (n = 279) or control (n = 314) groups.
The primary outcome was the perception that vaping is less harmful than smoking. Secondary outcomes were perceptions that vaping is harmful, vaping is addictive and responses (true, false) to statements that were matched to the videos (e.g. vaping causes cancer, vaping causes lung injuries).
After exposure to an expert video, compared with those in the control group, participants in the intervention group had over three times the odds of perceiving vaping as less harmful than smoking [82.1% vs 57.6%; adjusted odds ratio (AOR) = 3.69; 95% confidence interval (95% CI) = 2.49-5.47; P < 0.001]. Perceptions that the following statements are false were also higher after viewing expert videos than control videos: vaping causes lung injury, vaping leads to cancer, nicotine is harmful when used in ways that does not involve smoking tobacco, pregnant women should not vape, vaping will not help you quit smoking, vaping has no place on the NHS (all P < 0.05). Participants exposed to the 'vaping is as harmful as smoking' misconception video had the highest odds of accurately perceiving vaping as less harmful than smoking (AOR = 13.92; 95% CI = 3.26-59.37; P < 0.001). Videos specifically targeting individual misconceptions (e.g. 'vaping causes lung injury' or 'vaping causes cancer') were particularly effective in improving related perceptions, indicating that the videos functioned as designed. There was little evidence of associations between condition and perceiving that vaping is not harmful (AOR = 2.57; 95% CI = 0.78-8.52; P = 0.122) or not addictive (AOR = 0.49; 95% CI = 0.04-6.67; P = 0.594). Findings were similar among young adults regardless of vaping and smoking status.
Brief, academic-led, vaping facts films appear to be effective in correcting vaping misperceptions and dispelling common misconceptions.
评估由学术主导、基于证据的简短社交媒体视频对年轻成年人电子烟危害认知的影响。
在线组间实验研究。参与者被随机分为两种情况之一：实验组（观看八个为社交媒体设计的简短视频之一，由学术专家讲解电子烟危害）或对照组。在观看视频前后，所有参与者都回答了关于他们对电子烟和吸烟的认知以及社会人口统计学的问题。
Qualtrics在线调查平台。
593名年龄在18至30岁之间居住在英国的年轻成年人（49.7%为女性，49.2%为男性；8.9%仅吸烟，32%仅吸电子烟，28.7%两者都做，30.4%两者都不做）。参与者被随机分配到干预组（n = 279）或对照组（n = 314）。
主要结果是认为吸电子烟比吸烟危害小的认知。次要结果是认为电子烟有害、电子烟会上瘾以及对与视频内容匹配的陈述（如电子烟会导致癌症、电子烟会导致肺部损伤）的回答（是、否）。
观看专家视频后，与对照组相比，干预组参与者认为吸电子烟比吸烟危害小的几率高出三倍多[82.1%对57.6%；调整后的优势比（AOR）= 3.69；95%置信区间（95%CI）= 2.49 - 5.47；P < 0.001]。观看专家视频后，对以下陈述为假的认知也高于对照组:电子烟会导致肺部损伤、电子烟会导致癌症、以不涉及吸烟的方式使用尼古丁是有害的、孕妇不应吸电子烟、吸电子烟无助于戒烟、电子烟在国民医疗服务体系中没有立足之地（所有P < 0.05）。观看“吸电子烟与吸烟危害一样大”错误观念视频的参与者准确认为吸电子烟比吸烟危害小的几率最高（AOR = 13.92；95%CI = 3.26 - 59.37；P < 0.001）。专门针对个别错误观念（如“电子烟会导致肺部损伤”或“电子烟会导致癌症”）的视频在改善相关认知方面特别有效，表明这些视频按设计发挥了作用。几乎没有证据表明情况与认为电子烟无害（AOR = 2.57；95%CI = 0.78 - 8.52；P = 0.122）或不上瘾（AOR = 0.49；95%CI = 0.04 - 6.67；P = 0.594）之间存在关联。无论电子烟和吸烟状况如何，年轻成年人中的结果相似。
由学术主导的简短电子烟事实影片似乎在纠正对电子烟的错误认知和消除常见误解方面有效。
