Videos on YouTube, Bilibili, TikTok as Sources of Medical Information on Hashimoto’s Thyroiditis (Preprint)

Le résumé fourni par la source

BACKGROUND Hashimoto’s thyroiditis (HT), a common autoimmune thyroid disorder, is widely discussed on video-sharing platforms. However, user-generated content about HT lacks systematic scientific validation. OBJECTIVE This study evaluates the reliability and quality of HT-related videos on three major social media platforms: YouTube, Bilibili, and TikTok. METHODS Between December 1-10, 2024, a total of 600 HT-related videos meeting the criteria were analyzed: 200 from YouTube (107 content creators), 200 from Bilibili (56 creators), and 200 from TikTok (90 creators). Metrics including video parameters and creator profiles were recorded. Content quality was evaluated using five validated assessment tools: PEMAT (Patient Education Materials Assessment Tool), VIQI (Video Information and Quality Index), GQS (Global Quality Score), mDISCERN (modified DISCERN), and JAMA (Journal of the American Medical Association) standards. RESULTS TikTok videos showed the highest audience engagement. YouTube had more team-based accounts, while TikTok and Bilibili predominantly featured individual accounts, with TikTok featuring a notably higher proportion of verified individual accounts. Solo narration was the most common video style across YouTube and TikTok, while in Bilibili, it was the medical scenario. In contrast, YouTube and Bilibili offered a broader range of content, including TV programs, documentaries, and educational courses. The varying emphases of different assessment tools rendered it difficult to determine which platform boasts the highest content quality, but the video quality scores across all platforms are not satisfying. Additionally, we found that content produced by verified creators was of higher quality compared to that of unverified creators, with this trend being particularly evident among individual accounts. CONCLUSIONS Social media platforms can help disseminate knowledge about HT to some extent. The video quality across all platforms requires improvement. We recommend that professional creators pursue platform certification to enhance the dissemination of high-quality HT-related videos.
