背景:YouTube,一个广受认可的全球视频平台,在中国是无法进入的,而Bilibili和TikTok是长短视频的热门平台,分别。在这些平台上有许多与喉癌有关的视频。本研究旨在识别上传来源,内容,以及YouTube上这些视频的专题信息,Bilibili,和TikTok,并进一步评估视频质量。
方法:在2024年1月1日,我们在YouTube上按默认排序顺序搜索了前100个视频(总共300个视频),并带有术语“喉癌”和“喉癌”,“\”在Bilibili和TikTok上。筛选视频的相关性和相似性。视频特征被记录下来,质量通过使用患者教育材料评估工具(PEMAT)进行评估,视频信息和质量指数(VIQI)全球质量评分(GQS),并修改了DISCERN(MDISCERN)。
结果:分析包括99个YouTube视频,76来自Bilibili,73来自TikTok。视频长度的中位数为193s(YouTube),136s(比利比利),和42s(TikTok)。TikTok视频展示了更高的受众互动。Bilibili的原始含量比率最低(69.7%)。治疗是YouTube和Bilibili上最受欢迎的话题,这就是TikTok的预后。独奏叙述是所有平台上最常见的视频风格。视频上传者主要是非营利组织(YouTube),自媒体(Bilibili),和医生(TikTok)TikTok作者的认证率最高(83.3%)。视频质量,使用PEMAT评估,VIQI,GQS,和mDISCERN,不同的平台,YouTube通常显示最高分。根据GQS和mDISCERN评分,来自专业作者的视频比非专业人士的视频表现更好。Spearman相关分析表明,视频质量与观众互动之间没有很强的关系。
结论:社交媒体平台上的视频可以在一定程度上帮助公众了解喉癌的知识。TikTok实现了最佳流量,但是YouTube上的视频质量最好。然而,所有平台的视频质量仍需提高。我们需要更多的专业上传器来改善与喉癌相关的视频质量。内容创建者还应该了解认证,原创性,以及视频拍摄的风格。至于平台,改进算法将允许用户接收更多高质量的视频。
BACKGROUND: YouTube, a widely recognized global video platform, is inaccessible in China, whereas Bilibili and TikTok are popular platforms for long and short videos, respectively. There are many videos related to laryngeal carcinoma on these platforms. This
study aims to identify upload sources, contents, and feature information of these videos on YouTube, Bilibili, and TikTok, and further evaluate the video quality.
METHODS: On January 1, 2024, we searched the top 100 videos by default sort order (300 videos in total) with the terms \"laryngeal carcinoma\" and \"throat cancer\" on YouTube, \"\" on Bilibili and TikTok. Videos were screened for relevance and similarity. Video characteristics were documented, and quality was assessed by using the Patient Education Materials Assessment Tool (PEMAT), Video Information and Quality Index (VIQI), Global Quality Score (GQS), and modified DISCERN (mDISCERN).
RESULTS: The analysis included 99 YouTube videos, 76 from Bilibili, and 73 from TikTok. Median video lengths were 193 s (YouTube), 136 s (Bilibili), and 42 s (TikTok). TikTok videos demonstrated higher audience interaction. Bilibili had the lowest ratio of original contents (69.7%). Treatment was the most popular topic on YouTube and Bilibili, while that was the prognosis on TikTok. Solo narration was the most common video style across all platforms. Video uploaders were predominantly non-profit organizations (YouTube), self-media (Bilibili), and doctors (TikTok), with TikTok authors having the highest certification rate (83.3%). Video quality, assessed using PEMAT, VIQI, GQS, and mDISCERN, varied across platforms, with YouTube generally showing the highest scores. Videos from professional authors performed better than videos from non-professionals based on the GQS and mDISCERN scores. Spearman correlation analysis showed no strong relationships between the video quality and the audience interaction.
CONCLUSIONS: Videos on social media platforms can help the public learn about the knowledge of laryngeal cancer to some extent. TikTok achieves the best flow, but videos on YouTube are of the best quality. However, the video quality across all platforms still needs enhancement. We need more professional uploaders to ameliorate the video quality related to laryngeal carcinoma. Content creators also should be aware of the certification, the originality, and the style of video shooting. As for the platforms, refining the algorithm will allow users to receive more high-quality videos.
