To examine the content, quality and reliability of YouTube videos related to breast self-examination.
A search of YouTube was made on 21.06.2018 using the keyword of "breast self-examination". The videos were categorised by two doctors as useful information or misleading information. To evaluate the quality of the videos, a 5-point global quality scale was used (GQS: 1 = poor quality, 5 = excellent quality), for reliability a 5-point DISCERN scale was used, and for content an 8-point scale (higher points indicated greater reliability and better content).
Of the 200 videos initially included in the study, 33 (37.9%) were classified as useful and 54 (62%) as misleading information. The reliability, content and quality scores of the videos in the useful information group were higher. The length (in seconds) of the videos in the useful information group (median 301, IQR 231-512) was longer than that of those in the misleading information group (median 163, IQR 94.8-231) (p = 0.003). The majority (70.6%) of the videos in the misleading information group had been uploaded by an individual user. The number of views per day of the videos in the misleading information group (median 58.6, IQR 18.5-298) was greater than that of the videos in the useful information group (median 49.7, IQR 16.3-268) (p = 0.276). The number of total views was higher for the misleading information group (median 83807 vs. 80237) but not at a level of statistical significance (p = 0.153). There were more videos explaining breast self-examination directed at women only, and there were determined to be few videos including men only or both genders.
Although there are many videos in English related to breast self-examination on YouTube, a great many of these contain misleading information. Therefore, for public information, there is a need for videos with full and accurate information to be made by universities, healthcare organisations and doctors not benefitting from the outcomes, to be uploaded to YouTube, which is a currently important source of information for the general population.
检查与乳房自检相关的 YouTube 视频的内容、质量和可靠性。
于 2018 年 6 月 21 日在 YouTube 上使用“乳房自检”关键词进行搜索。由两位医生将视频分为有用信息和误导性信息两类。为了评估视频的质量，使用了 5 分制整体质量评分（GQS：1=质量差，5=质量优），为评估可靠性使用了 5 分 DISCERN 评分，为评估内容使用了 8 分制（分数越高表示可靠性越高，内容越好）。
最初纳入研究的 200 个视频中，33 个（37.9%）被归类为有用信息，54 个（62%）为误导性信息。有用信息组视频的可靠性、内容和质量评分更高。有用信息组视频的时长（以秒计，中位数 301，IQR 231-512）长于误导性信息组（中位数 163，IQR 94.8-231）（p=0.003）。误导性信息组中，大部分（70.6%）视频由个人用户上传。误导性信息组视频的日观看次数（中位数 58.6，IQR 18.5-298）多于有用信息组（中位数 49.7，IQR 16.3-268）（p=0.276）。误导性信息组的总浏览量更高（中位数 83807 与 80237），但差异无统计学意义（p=0.153）。有更多专门针对女性的乳房自检视频，只有男性或男女都有的视频很少。
虽然 YouTube 上有很多关于乳房自检的英文视频，但很多视频都包含误导性信息。因此，为了公众信息，需要由大学、医疗机构和不依赖结果的医生制作内容全面、准确的视频，并上传至 YouTube，这是目前普通民众的一个重要信息来源。
