Evaluating the reliability and quality of lupus nephritis educational content on TikTok and Bilibili: a cross-sectional content analysis
Authors' conclusion
The quality of LN-related information on short-video platforms varies widely, with popularity metrics poorly reflecting scientifically assessed content quality.
Study context
- Population
- Lupus nephritis (LN)-related short videos on TikTok and Bilibili
- Participants
- 250 videos
- Exposure
- TikTok vs Bilibili LN-related short videos; professional vs non-professional uploaders
- TikTokn = 143
- Bilibilin = 107
- Outcome
- Video quality and reliability (GQS, mDISCERN, content completeness)
Methodological detailscontent analysis, independent evaluation by three senior rheumatology clinicians, Spearman correlation analysis
- Content analysis
- Independent evaluation by three senior rheumatology clinicians
- Spearman correlation analysis
Main finding
As reported in the abstract
- No significant difference in overall Global Quality Score (GQS) between platforms
- p>0.05
- TikTok achieved a slightly higher modified DISCERN (mDISCERN) score
- p<0.05
- TikTok videos provided more comprehensive coverage of clinical manifestations and treatment
- p<0.05
- Professional institutions significantly outperformed non-professional uploaders across all quality indicators
- p<0.05
Observational data: associations, not effects.
Further findings
User engagement and uploader type
- Engagement indicators (likes, comments, shares, favourites) and proportion of professional uploaders significantly higher on TikTok than Bilibili
- P < 0.05
- Bilibili videos significantly longer
Engagement vs quality correlation
- Strong positive correlations among engagement indicators; major popularity metrics showed limited alignment with scientific quality scores
