YouTube is an important online source of information and has two billion users globally. Its viewing numbers tend to increase exponentially in extraordinary global situations. Our aim in this study was to review and evaluate the contents of the most frequently viewed YouTube videos during the Coronavirus disease 2019 (COVID-19) pandemic. Methods: In this qualitative study, contents of the most frequently viewed Turkish and English YouTube videos regarding the COVID-19 pandemic were examined and scored with modified DISCERN, medical information and content index (MICI), and video power index (VPI) during April 2020.
The mean DISCERN score of Turkish videos was similar to that of English videos (2.55±1.40 and 2.43±1.25, respectively). The total MICI score tended to be higher in Turkish videos. News channels released 86.9% of all 168 videos and 65.2% of all 23 misleading videos. When the descriptive characteristics of videos were compared in terms of their content category, average view counts, view ratios, and VPIs of misleading videos were higher than those of the useful videos. Only, the likes ratio of useful videos was higher than that of the misleading videos.
Since there is no peer-review system on YouTube, people can almost release every type of video. It is very important for the content of videos that are released through news channels to be accurate because the important messages can be spread among people in society through them. In our study, especially some Turkish videos included many different rumors and faulty statements. During the extraordinary situations such as the pandemic, the videos of official health authorities and international institutions should be more visible on YouTube.
YouTube是一个重要的在线信息来源，全球有20亿用户。在全球特殊情况下，其观看量往往呈指数级增长。我们开展这项研究的目的是回顾和评估2019冠状病毒病（COVID-19）大流行期间YouTube上观看次数最多的视频内容。
在这项定性研究中，我们于2020年4月检查了YouTube上观看次数最多的关于COVID-19大流行的土耳其语和英语视频的内容，并用改良的DISCERN、医学信息与内容指数（MICI）和视频影响力指数（VPI）进行评分。
土耳其语视频的平均DISCERN评分与英语视频相似（分别为2.55±1.40和2.43±1.25）。土耳其语视频的MICI总分往往更高。新闻频道发布了所有168个视频中的86.9%以及所有23个误导性视频中的65.2%。当根据视频的内容类别、平均观看次数、观看比例和VPI对视频的描述性特征进行比较时，误导性视频的上述指标高于有用视频。只有有用视频的点赞比例高于误导性视频。
由于YouTube上没有同行评审系统，人们几乎可以发布任何类型的视频。通过新闻频道发布的视频内容准确非常重要，因为重要信息可以通过它们在社会人群中传播。在我们的研究中，特别是一些土耳其语视频包含了许多不同的谣言和错误陈述。在大流行等特殊情况下，官方卫生当局和国际机构的视频在YouTube上应更具可见性。
