The reliability and educational quality of TikTok videos addressing insomnia management remain uncertain. A total of 127 TikTok videos were assessed with Global Quality Score (GQS) for educational value and with Viewing and Engagement Index for popularity. Among these, 66 videos by general users, 20 by physicians, 32 by other healthcare professionals, and 9 by brand-affiliated accounts showed overall poor quality: only 20 videos (15.7%) had high educational value, while another 11 (8.7%) had moderate educational value; only 5 videos received the highest score for consistency with guidelines, only 5 videos recommended consulting a physician, and only 2 included scientific references. Approximately 55% of physicians' videos had GQS ≥ 3, compared with 25%, 18%, and 0% of other healthcare professionals, general users, and brand accounts respectively. GQS was not correlated with engagement metrics. Sponsored videos were associated with lower-quality content. In conclusion, TikTok videos related to insomnia management generally do not provide reliable, guidelines-based information, raising concerns regarding the use of TikTok as a source of insomnia management information.
