Many pro-smoking videos on YouTube reach view counts in the hundreds of thousands and more. Yet, there is limited information on who is viewing these potentially misleading videos. This study attempts to understand the viewership of online pro-smoking videos to examine if youth at high risk for smoking are more likely to watch these videos.
We conducted a selective exposure experiment with a national sample of youths (ages 15-21 years; n = 614) to identify characteristics that make individuals more likely to select pro-smoking videos. During a 10-min browsing session, participants were given a set of 16 videos (eight smoking and eight nonsmoking) and were asked to view video(s) of their choice. Exposure to videos was unobtrusively logged. View count was manipulated such that smoking videos had either high or low views.
Behavioral data revealed that youth with higher interest in smoking were more likely to select and spend more time watching pro-smoking videos than youth with lower interest in smoking. The view count manipulation did not affect selection patterns. However, exposure to high view count smoking videos was associated with more positive attitudes toward smoking.
The findings of this study call into question the existence and prominence of pro-smoking videos on YouTube and bring to attention the need for regulatory or monitoring efforts of such content.
Given the presence and prevalence of misleading pro-smoking videos online, this is the first study to ask the practical and important question of who is viewing these videos. Using behavioral data, we are able to demonstrate that youth who are high at risk for smoking are more susceptible to select and spend more time viewing pro-smoking videos than youth who are low at risk for smoking. Findings also show that when pro-smoking videos appear to be "popular," they affect attitudes toward smoking. Our findings provide policy implications regarding regulation of smoking promotion videos online.
许多支持吸烟的 YouTube 视频的浏览量达到数十万甚至更多。然而,关于谁在观看这些可能具有误导性的视频,信息有限。本研究试图了解在线支持吸烟视频的观看情况,以检查是否有吸烟高风险的年轻人更有可能观看这些视频。
我们对全国范围内的青少年(年龄在 15-21 岁之间;n=614)进行了选择性暴露实验,以确定使个体更有可能选择支持吸烟视频的特征。在 10 分钟的浏览过程中,参与者观看了一组 16 个视频(8 个吸烟视频和 8 个不吸烟视频),并被要求选择他们选择的视频。对视频的观看情况进行了不显眼的记录。视频的观看次数被操纵,使吸烟视频的观看次数要么高要么低。
行为数据显示,对吸烟更感兴趣的青少年比对吸烟兴趣较低的青少年更有可能选择并花更多时间观看支持吸烟的视频。观看次数的操纵并不影响选择模式。然而,观看高观看次数的吸烟视频与对吸烟的更积极态度有关。
本研究的结果对 YouTube 上存在和突出的支持吸烟视频提出了质疑,并引起了对这种内容进行监管或监控的必要性的关注。
鉴于在线上存在和流行具有误导性的支持吸烟视频,这是第一项询问谁在观看这些视频的实际和重要问题的研究。使用行为数据,我们能够证明吸烟高风险的青少年比吸烟低风险的青少年更容易选择和花更多时间观看支持吸烟的视频。研究结果还表明,当支持吸烟的视频看起来“受欢迎”时,它们会影响对吸烟的态度。我们的研究结果为在线上监管吸烟促销视频提供了政策意义。
