Breast cancer, the most common cancer in women globally, highlights the need for patient education. Despite many breast cancer discussions on TikTok, their scientific evaluation is lacking. Our study seeks to assess the content quality and accuracy of popular TikTok videos on breast cancer, to improve the dissemination of health knowledge.
On August 22, 2023, we collected the top 100 trending videos from TikTok's Chinese version using "breast cancer/breast nodule" as keywords. We noted their length, TikTok duration, likes, comments, favorites, reposts, uploader types, and topics. Four assessment tools were used: Goobie's six questions, the Patient Educational Material Assessment Tool (PEMAT), the Video Information and Quality Index (VIQI), and the Global Quality Score (GQS). These instruments evaluate videos based on content, informational integrity, and overall quality.
Among the 100 videos, content quality was low with Goobie's questions mostly scoring 0, except for management at 1.0 (QR 1.0). PEMAT scores were moderate: 54.1 (QR 1.6) for sum, 47.0 (QR 18.8) for PEMAT-A, and 52.3 (QR 11.7) for PEMAT-U. Regarding the quality of information, the VIQI (sum) median was 14.1 (QR 0.2). Additionally, the median GQS score was 3.5 (QR 0.1). Medical professionals' videos focused on breast cancer stages, while patient videos centered on personal experiences. Patient videos had lower content and overall quality compared to those by medical professionals (PEMAT, GQS: < 0.001, = 0.004) but received more comments, indicating higher engagement (all < 0.05).
TikTok's breast cancer content shows educational potential, but while informational quality is moderate, content quality needs improvement. Videos by medical professionals are of higher quality. We recommend increased involvement of healthcare professionals on TikTok to enhance content quality. Non-medical users should share verified information, and TikTok should strengthen its content vetting. Users must scrutinize the credibility of health information on social platforms.
乳腺癌是全球女性中最常见的癌症，这凸显了患者教育的必要性。尽管TikTok上有许多关于乳腺癌的讨论，但缺乏对其的科学评估。我们的研究旨在评估TikTok上热门乳腺癌视频的内容质量和准确性，以促进健康知识的传播。
2023年8月22日，我们以“乳腺癌/乳腺结节”为关键词，从TikTok中文版收集了前100个热门视频。我们记录了它们的时长、TikTok时长、点赞数、评论数、收藏数、转发数、上传者类型和主题。使用了四种评估工具：古比的六个问题、患者教育材料评估工具（PEMAT）、视频信息与质量指数（VIQI）和全球质量评分（GQS）。这些工具基于内容、信息完整性和整体质量对视频进行评估。
在100个视频中，内容质量较低，古比的问题大多得0分，只有管理方面得1.0分（四分位数间距1.0）。PEMAT得分中等：总和为54.1（四分位数间距1.6），PEMAT-A为47.0（四分位数间距18.8），PEMAT-U为52.3（四分位数间距11.7）。关于信息质量，VIQI（总和）中位数为14.1（四分位数间距0.2）。此外，GQS得分中位数为3.5（四分位数间距0.1）。医学专业人员的视频关注乳腺癌分期，而患者视频则以个人经历为中心。与医学专业人员的视频相比，患者视频的内容和整体质量较低（PEMAT、GQS：<0.001，=0.004），但收到的评论更多，表明参与度更高（均<0.05）。
TikTok上的乳腺癌内容显示出教育潜力，但虽然信息质量中等，但内容质量需要改进。医学专业人员的视频质量更高。我们建议医疗保健专业人员更多地参与TikTok，以提高内容质量。非医学用户应分享经过验证的信息，TikTok应加强其内容审核。用户必须仔细审查社交平台上健康信息的可信度。
