Objective: Social networks share medical content with no peer-review or fact-checking. In the present study we aimed to assess the quality, reliability, and level of misinformation in TikTok videos about polycystic ovary syndrome (PCOS). Methods: We performed a cross-sectional analysis of TikTok videos retrieved using “PCOS” as the search term and analyzed using patient education materials assessment tool for audio-visual content (PEMAT A/V), modified DISCERN (mDISCERN), global quality scale (GQS), video information and quality index (VIQI) and misinformation assessment were employed. Results: A total of 180 videos were included. Most videos were partially accurate (containing 25%–50% of false information) or uninformative (more than 50%) (56.7% and 6.6%, respectively) with a significantly higher proportion of inaccurate or uninformative videos from PCOS-patients than healthcare professionals (14.4% vs. 0%; P < 0.001) as well as for partially accurate videos (78.4% vs. 37.5%; P < 0.001). PEMAT A/V scores for understandability and actionability were 50% (interquartile range [IQR]: 33%–58%) and 25% (IQR: 25%–50%), respectively with significantly higher understandability for healthcare professionals (54% [IQR: 42%–71%] vs. 33% [IQR: 25%–50%], P < 0.001). Median mDISCERN was 2 (IQR: 1–3) (low degree of reliability), with videos by healthcare professionals scoring significantly higher than those by patients (2 [IQR: 2–3] vs. 1 [IQR: 0–2]; P = 0.001). Intermediate-low overall video quality was reported in VIQI with median score of 12 (IQR: 10–15) and significantly lower scores for patients (9 [IQR: 5–12] vs. 13 [IQR: 12–17]; P < 0.001). Similarly, median GQS score was overall intermediate for degree of usefulness (median 3 [IQR: 2–4]), but patient-created videos were of significantly lower quality (median 2 [IQR: 2–3] vs. 4 [IQR: 3–4]; P < 0.001). Conclusion: PCOS-related videos on TikTok were mostly misinformative and of low quality and reliability. Healthcare professionals' videos were more informative with had higher quality compared to patient-created content. Identifying and addressing low-quality content is crucial for guiding future public health initiatives and improving the dissemination of trustworthy medical information on social networks.

In the present study we aimed to assess the quality, reliability, and level of misinformation in TikTok videos about polycystic ovary syndrome (PCOS). Methods: We performed a cross-sectional analysis of TikTok videos retrieved using “PCOS” as the search term and analyzed using patient education materials assessment tool for audio-visual content (PEMAT A/V), modified DISCERN (mDISCERN), global quality scale (GQS), video information and quality index (VIQI) and misinformation assessment were employed.
