YouTube is one of the largest social networking websites, allowing users to upload and view video content that provides entertainment and conveys many messages, including those related to health conditions, such as concussion. However, little is known about the content of videos relating to concussion.
To identify and classify the content of concussion-related videos available on YouTube.
An observational study using content analysis.
YouTube's video database was systematically searched using 10 search terms selected from MeSH and Google Adwords. The 100 videos with the largest view counts were chosen from the identified videos. These videos and their accompanying text were analysed for purpose, source and description of content by a panel of assessors who classified them into data-driven thematic categories.
434 videos met the inclusion criteria and the 100 videos with the largest view counts were chosen. The most common categories of the videos were the depiction of a sporting injury (37%) and news reports (25%). News and media organisations were the predominant source (51%) of concussion-related videos on YouTube, with very few being uploaded by professional or academic organisations. The median number of views per video was 26 191.
Although a wide range of concussion-related videos were identified, there is a need for healthcare and educational organisations to explore YouTube as a medium for the dissemination of quality-controlled information on sports concussion.
YouTube 是最大的社交网站之一，允许用户上传和观看视频内容，这些内容提供娱乐并传达许多信息，包括与健康状况相关的信息，如脑震荡。然而，人们对与脑震荡相关的视频内容知之甚少。
确定并分类 YouTube 上与脑震荡相关的视频内容。
采用观察性研究，使用内容分析法。
从 MeSH 和 Google Adwords 中选择了 10 个搜索词，对 YouTube 的视频数据库进行系统搜索。从已识别的视频中选择观看次数最多的 100 个视频。由一组评估人员对这些视频及其附带的文字进行分析，以确定目的、来源和内容描述，并将其分类为数据驱动的主题类别。
有 434 个视频符合纳入标准，选择了观看次数最多的 100 个视频。视频最常见的类别是体育损伤的描述（37%）和新闻报道（25%）。新闻和媒体组织是 YouTube 上与脑震荡相关视频的主要来源（51%），很少有专业或学术组织上传此类视频。每个视频的平均观看次数为 26191 次。
尽管已经确定了广泛的与脑震荡相关的视频，但医疗保健和教育组织需要探索 YouTube 作为传播有关运动性脑震荡的高质量信息的媒介。
