Abstract
In recent years, short-form videos have demonstrated substantial potential in disseminating health-related information, with TikTok and Bilibili emerging as major platforms for public access to such content. However, to the best of our knowledge, no studies have systematically evaluated the quality and reliability of anxiety disorder-related videos on short-video platforms. Therefore, this study aimed to assess the quality and reliability of anxiety-related short videos on TikTok and Bilibili. A total of 250 anxiety disorder-related videos were analyzed from TikTok and Bilibili. Data on video characteristics, uploader identity, and engagement metrics were collected. The Global Quality Score and modified DISCERN were used to assess quality and reliability. The Mann-Whitney U test and Kruskal-Wallis H test were used for group comparisons, and Spearman rank correlation was applied to assess the relationships between engagement and video quality. The study revealed significant differences between the 2 platforms in video length, quality, reliability, and engagement metrics. Specifically, TikTok videos were shorter (median: 96 seconds, interquartile range [IQR]: 56.00-171.50) and received higher engagement (median likes: 5916, median shares: 2016) compared with Bilibili videos (median: 564 seconds, IQR: 200.00-1004.50, median likes: 611, median shares: 135). Videos uploaded by specialists exhibited higher quality and reliability, with a median Global Quality Score of 3.00 (IQR: 2.00-3.00) and a median modified DISCERN score of 2.00 (IQR: 2.00-3.00), significantly outperforming those uploaded by nonspecialists and individual users (P < .05). Content analysis indicated that most videos focused on symptoms (82.4%) and treatment (53.6%), while crucial topics such as diagnosis (9.2%), prevention (9.6%), and epidemiology (4.8%) were less frequently discussed. Anxiety disorder-related videos on TikTok and Bilibili have moderate quality and reliability. Specialist-uploaded videos are superior in quality. Key topics such as diagnosis and prevention should be better covered, and content moderation and professional involvement should be strengthened.
