Data Sheet 1_A cross-sectional study on the quality and reliability of short videos related to precancerous cervical lesions on major platforms.docx

Objective<p>To evaluate the quality, reliability, and educational value of videos related to precancerous cervical lesions across four major short-video platforms in China (TikTok, Bilibili, Kwai, and Xiaohongshu), using multiple validated evaluation tools.</p>Methods<p>A total of 1842 short videos were collected, assessed using GQS, JAMA, modified DISCERN, PEMAT, and HONcode tools. The videos were analyzed for quality, reliability, educational value, and engagement metrics (likes, comments, collections, shares).</p>Results<p>Videos on TikTok consistently achieved the highest scores for quality, reliability, and transparency across all scoring systems.

In contrast, Bilibili, Kwai, and Xiaohongshu exhibited variable performance. Videos created by medical practitioners, particularly gynecologists, scored higher compared to those uploaded by non-medical practitioners. Content focusing on basic disease knowledge had higher educational value than prevention or post-treatment videos.
