Hypertrophic scars (HTSs) are a predominant condition after burns and trauma, and it causes severe physiological and psychological problems. TikTok (Douyin in Chinese), a popular platform for sharing short videos, has shown the potential to spread health information, including information related to HTSs. Educating the public to obtain correct information is important to reduce the incidence of physiological and psychological problems caused by HTSs. However, the quality and reliability of HTS-related video content on TikTok in mainland China have not been thoroughly studied.
This study aims to evaluate the content and quality of short videos related to HTSs on the Chinese version of TikTok (Douyin) and explore the factors related to their quality, providing valuable insights for health information dissemination.
We collected a sample of 153 TikTok videos in Chinese related to HTSs and categorized them according to video source and content. We evaluated the video content using a coding schema, and a hexagonal radar schema was used to intuitively display the spotlight and weight of each aspect of the videos. We evaluated quality using 4 standardized tools: the modified DISCERN (mDISCERN) questionnaire, the Journal of the American Medical Association, the Global Quality Scale (GQS), and the Health on the Net Foundation Code of Conduct. We also explored the potential relationship between video quality and characteristics.
The analysis showed that health care professionals uploaded all videos about treating HTSs, which matched the hexagonal radar model analysis findings. The quality assessment scores for the Journal of the American Medical Association, GQS, mDISCERN, and the Health on the Net Foundation Code of Conduct had median values of 1 (IQR 1-2), 2 (IQR 2-3), 2 (IQR 2-3), and 3 (IQR 3-4), respectively, indicating a need to improve the quality and reliability of videos on HTSs. In addition, high-quality videos were more popular, based on metrics such as likes, comments, favorites, and shares (P<.001). Interestingly, the time when the videos were uploaded positively correlated with GQS and mDISCERN scores (r=0.393; P<.001 and r=0.273; P<.001), while the video length did not significantly correlate with evaluation scores (P=.78, P=.20, P=.07, and P=.04).
The quality of TikTok videos related to HTSs is generally moderate. Users should exercise caution when seeking information on HTSs from TikTok. It is advisable to choose videos uploaded by health care professionals from the burn department and the burn plastic surgery department, and in the Chinese context, those produced in first-tier cities and emerging first-tier cities.
增生性瘢痕（HTS）是烧伤和创伤后的主要病症，会引发严重的生理和心理问题。抖音是一个热门短视频分享平台，已显示出传播健康信息的潜力，包括与增生性瘢痕相关的信息。教育公众获取正确信息对于减少增生性瘢痕导致的生理和心理问题的发生率至关重要。然而，中国大陆抖音上与增生性瘢痕相关的视频内容的质量和可靠性尚未得到充分研究。
本研究旨在评估中文版抖音上与增生性瘢痕相关的短视频的内容和质量，并探索与其质量相关的因素，为健康信息传播提供有价值的见解。
我们收集了153条中文抖音上与增生性瘢痕相关的视频样本，并根据视频来源和内容进行分类。我们使用编码方案评估视频内容，并使用六边形雷达图直观展示视频各方面的重点和权重。我们使用4种标准化工具评估质量：改良的DISCERN（mDISCERN）问卷、《美国医学会杂志》、全球质量量表（GQS）和网络健康基金会行为准则。我们还探索了视频质量与特征之间的潜在关系。
分析表明，所有关于增生性瘢痕治疗的视频均由医护人员上传，这与六边形雷达模型分析结果相符。《美国医学会杂志》、GQS、mDISCERN和网络健康基金会行为准则的质量评估得分中位数分别为1（四分位间距1 - 2）、2（四分位间距2 - 3）、2（四分位间距2 - 3）和3（四分位间距3 - 4），表明需要提高增生性瘢痕相关视频的质量和可靠性。此外，基于点赞、评论、收藏和分享等指标，高质量视频更受欢迎（P <.001）。有趣的是，视频上传时间与GQS和mDISCERN得分呈正相关（r = 0.393；P <.001和r = 0.273；P <.001），而视频长度与评估得分无显著相关性（P =.78、P =.20、P =.07和P =.04）。
抖音上与增生性瘢痕相关的视频质量普遍中等。用户在从抖音上寻求增生性瘢痕相关信息时应谨慎。建议选择由烧伤科和烧伤整形外科的医护人员上传的视频，在中国背景下，优先选择一线城市和新一线城市制作的视频。
