Evaluating the quality and reliability of endometrial cancer related videos on Chinese short-video platforms: A...

ObjectiveTo conduct a multidimensional evaluation of endometrial cancer (EC)-related videos on major Chinese short-video platforms.MethodsA cross-sectional study conducted on May 8, 2025 analyzed 226 eligible EC-related videos from TikTok, Rednote, and Bilibili. Video quality was assessed using Global Quality Scale (GQS) and Video Information and Quality Index (VIQI), reliability using modified DISCERN (mDISCERN), and understandability and actionability using Patient Education Materials Assessment Tool (PEMAT).ResultsAmong 226 videos, TikTok emphasized symptoms/risk factors and scored highest in engagement, reliability (mDISCERN=2.0, P=0.002), and understandability (88%). Bilibili led in VIQI (median=17.0) but had the lowest understandability (67%). Professional videos outperformed patient-generated content (all P<0.05). Video length correlated positively with quality but negatively with engagement and understandability (all P<0.01).ConclusionsEC-related videos vary widely in quality and lack consistent actionability. Strategic content design and platform-level verification are needed to improve reliability and public health impact.
