利用YouTube视频网站作为戒烟信息的一个来源
2010/12/16
摘要
目的：本试验分析在YouTube视频网站上的戒烟特异性视频与实际戒烟情况的相关性有多大，以及这种相关性是否存在循证依据(EBPs)。
方法：2008年8月，研究者采用戒烟、停止吸烟为主题词，检索YouTube视频网站与戒烟相关的视频及浏览次数（n=296为样本总数；n=191为特殊视频）。
结果：总体来说，约60%的视频包含有戒烟相关信息。不同的主题词检索出的视频存在差异，采用停止吸烟进行检索时，可以找到大部分与戒烟有关的视频（80.8%）。约48.9%的视频包括有关戒烟策略的EBPs。然而，相当一部分视频，或者无EBPs(28.4%)，或者同时包含有EBPs 和无EBPs(22.7%)。在6类视频中，每个视频的浏览次数，最低为8次（采用戒烟为主题词检索，并分析其相关性），最高达1 247 540次（采用停止吸烟为主题词检索，并分析其浏览次数）。基于分析策略和检索主题词，66.7%的视频包含有特别介绍戒烟的内容，在这些视频中，大部分包括有EBPs。
结论：我们的结果提示，有必要开发和上传包含有EBPs的相关视频，有助于增加EBP视频的总体比率，将特别有助于戒烟。有关YouTube视频对戒烟知识、态度和行为的影响还需进一步研究。

Abstract
Objective To conduct analyses to determine the extent to which YouTube videos posted specific to smoking cessation were actually about quitting smoking and if so, whether or not they portrayed evidence-based practices (EBPs). Methods In August 2008, researchers identified YouTube videos by search strategies, ’relevance’ and ’view count’ using the following three search terms: ’stop smoking’, ’quit smoking’ and ’smoking cessation (n=296 for full sample and n=191 for unique videos). Results Overall, almost 60% of videos contained a message about quitting smoking. Differences were found across search terms for videos about quitting smoking, with ’stop smoking’ yielding the highest percentage (80.8%) of videos about quitting smoking. Almost half of the videos (48.9%) contained EBPs for cessation strategies; however, a significant portion contained either non--EBPs (28.4%) or both EBPs and non-EBPs (22.7%). The number of views per an individual video across the six categories ranged from a low of 8 in the ’relevance’ strategy and ’smoking cessation’ search term to a high of 1 247 540 in the ’view count’ strategy and ’stop smoking’ search term. Of the top three most viewed videos by strategy and search term, 66.7% included a specific mention of quitting smoking and, of these, the majority included EBPs. Conclusion Results highlight the need to develop and upload videos containing EBPs both to increase the overall proportion of EBP videos in all categories, particularly in ’quit smoking’ and ’stop smoking.’ Research is needed to study whether YouTube videos influence knowledge, attitudes and behaviours regarding quitting smoking.
