BACKGROUND
Liver cancer incidence has been increasing in China in the recent years, leading to increased public concern regarding the burden of this disease. Short videos on liver cancer are disseminated through TikTok and Bilibili apps, which have gained popularity in recent years as an easily accessible source of health information. However, the credibility, quality, and usefulness of the information in these short videos and the professional knowledge of the individuals uploading health information-based videos in these platforms have not yet been evaluated.
OBJECTIVE
Our study aims to assess the quality of the information in Chinese short videos on liver cancer shared on the TikTok and Bilibili short video-sharing platforms.
METHODS
In March 2023, we assessed the top 100 Chinese short videos on liver cancer in TikTok and Bilibili (200 videos in total) for their information quality and reliability by using 2 rating tools, namely, global quality score (GQS) and the DISCERN instrument. Correlation and Poisson regression analyses were applied to discuss the factors that could impact video quality.
RESULTS
Compared to Bilibili, TikTok is more popular, although the length of the videos on TikTok is shorter than that of the videos on Bilibili (P<.001). The quality of the short videos on liver cancer in TikTok and Bilibili was not satisfactory, with median GQS of 3 (IQR 2-4) and 2 (IQR 1-5) and median DISCERN scores of 5 (IQR 4-6) and 4 (IQR 2-7), respectively. In general, the quality of videos sourced from professional institutions and individuals was better than that of those sourced from nonprofessionals, and videos involving disease-related knowledge were of better quality than those covering news and reports. No significant differences were found in the quality of videos uploaded by individuals from different professions, with the exception of those uploaded by traditional Chinese medicine professionals, which demonstrated poorer quality. Only video shares were positively correlated with the GQS (r=0.17, P=.01), and no video variables could predict the video quality.
CONCLUSIONS
Our study shows that the quality of short videos on health information related to liver cancer is poor on Bilibili and TikTok, but videos uploaded by health care professionals can be considered reliable in terms of comprehensiveness and content quality. Thus, short videos providing medical information on TikTok and Bilibili must be carefully considered for scientific soundness by active information seekers before they make decisions on their health care management.
背景
近年来，中国肝癌发病率不断上升，这导致公众对这种疾病的负担越来越关注。关于肝癌的短视频通过 TikTok 和 Bilibili 应用程序传播，近年来，这些应用程序作为易于获取健康信息的来源变得越来越受欢迎。然而，这些短视频中的信息的可信度、质量和有用性，以及在这些平台上上传健康信息相关视频的个人的专业知识尚未得到评估。
目的
我们的研究旨在评估在 TikTok 和 Bilibili 短视频分享平台上分享的关于肝癌的中文短视频的信息质量。
方法
2023 年 3 月，我们使用全球质量评分（GQS）和 DISCERN 工具评估了 TikTok 和 Bilibili 上排名前 100 的关于肝癌的中文短视频（共 200 个视频）的信息质量和可靠性。应用相关性和泊松回归分析来讨论可能影响视频质量的因素。
结果
与 Bilibili 相比，TikTok 更受欢迎，尽管 TikTok 上的视频长度比 Bilibili 上的短（P<.001）。TikTok 和 Bilibili 上关于肝癌的短视频质量都不尽如人意，中位数 GQS 分别为 3（IQR 2-4）和 2（IQR 1-5），中位数 DISCERN 分数分别为 5（IQR 4-6）和 4（IQR 2-7）。一般来说，来自专业机构和个人的视频质量要好于非专业人士的视频质量，涉及疾病相关知识的视频质量要好于新闻和报道类视频。除了中医专业人士上传的视频质量较差外，不同职业个人上传的视频质量没有显著差异。只有视频分享与 GQS 呈正相关（r=0.17，P=.01），没有视频变量可以预测视频质量。
结论
我们的研究表明，在 Bilibili 和 TikTok 上，与肝癌相关的健康信息短视频质量较差，但从全面性和内容质量来看，来自医疗保健专业人员的视频可以被认为是可靠的。因此，在 TikTok 和 Bilibili 上提供医疗信息的短视频，在信息寻求者做出其医疗保健管理决策之前，必须仔细考虑其科学性。
