The quality and reliability of short videos about migraine on Chinese social Media platforms (BiliBili and TikTok): A cross-sectional study
Abstract
Objective This cross-sectional study aimed to analyze the content and quality of migraine-related videos on Chinese video-sharing platforms. Background In recent years, the escalating incidence and prevalence of migraine have imposed an increasing burden on individuals. Short-video platforms, such as TikTok and BiliBili, have demonstrated immense potential for disseminating health-related information. While a substantial number of migraine-specific videos are available on TikTok and BiliBili, their quality and reliability remain largely uncharacterized. Method On 24 August 2025, short videos related to migraine were gathered from BiliBili and TikTok via a comprehensive Chinese language search. Following the extraction of fundamental information, each video was evaluated using the Global Quality Score (GQS), the modified DISCERN tool (mDISCERN) score, and the Patient Education Materials Assessment Tool (PEMAT). Furthermore, Spearman's correlation analysis was employed to investigate the relationships among video variables, GQS, DISCERN, and PEMAT scores. Results TikTok demonstrated greater popularity than BiliBili, evidenced by higher numbers of likes, collections, comments, and shares. Overall, short videos on TikTok generally received superior scores across all evaluation metrics compared to those on BiliBili. Furthermore, it was observed that videos shared by Neurology Professionals consistently scored higher in GQS, mDISCERN, PEMAT-U, and PEMAT-A than those from other…
