Evaluating Information Quality in French-Language TikTok Videos on Autism, Attention-Deficit/Hyperactivity Disorder, and Dyslexia

Social media platforms, including TikTok, have become popular sources of information on neurodevelopmental conditions. Previous studies indicate that 40–55% of English-language TikTok videos on autism or attention-deficit/hyperactivity disorder (ADHD) contain scientifically inaccurate information. However, the accuracy of comparable videos in other languages remains largely unknown. In this study, we evaluated the quality of information in 109 French-language TikTok videos on autism, ADHD, and dyslexia (with over 66 million cumulative views) to capture variation across disorders. The videos were identified using an ecologically valid keyword search and assessed by healthcare professionals with relevant scientific expertise. Results showed that 41% of autism videos, 56% of ADHD videos, and 41% of dyslexia videos were rated as “very poor” or “fairly poor” in terms of information quality because they contained major inaccuracies. Across all three disorders, higher-quality videos did not attract more views or interactions.
