Evaluating the Content, Quality, and Reliability of Migraine-related Videos on TikTok in China: Opportunities and Challenges for Health Information Dissemination.

This descriptive cross-sectional study investigated the content, quality, and reliability of migraine-related videos on TikTok. The top 200 migraine-related TikTok videos (176 eligible) were analyzed to assess content quality and reliability using Goobie's 6 questions and the DISCERN questionnaire. Although 98.8% (174/176) of the videos were physician-uploaded, 58.5% lacked disease definitions, and 34.7% omitted outcomes. While physician-uploaded videos had higher DISCERN scores, 36.93% still received a "poor" rating, and no correlation was found between video quality and engagement metrics (likes, shares) or duration. Despite TikTok's potential for health education, migraine-related content remains inconsistent and biased, highlighting the need for improved, evidence-based public health messaging on social media platforms. This study investigates the quality and reliability of migraine-related TikTok videos and identifies the issues, aiming to promote the improvement of migraine science video quality in the future.
