- This study evaluated the quality and reliability of amblyopia-related short videos on Bilibili and TikTok, finding them suboptimal with a median Global Quality Score (GQS) of 3.00 and modified DISCERN (mDISCERN) score of 3.00.
- Videos mainly focused on treatment (88.44%), while etiology and prevention were less discussed, highlighting gaps in content coverage for diagnosis and prevention.
- Videos uploaded by medical specialists had significantly higher quality and reliability scores compared to non-specialists and individual users, with a median GQS of 4.00.
- TikTok videos were shorter but had higher user engagement metrics (likes, comments, collections, shares) than Bilibili, though engagement did not correlate with video quality or reliability.
- Video duration showed a weak positive correlation with quality, but no differences in quality or reliability were found between the two platforms overall.
- The study recommends strengthening content review, oversight, and encouraging specialist participation to improve health information quality on short video platforms.
