Concerns about misinformation on social media have grown alongside the popularity of platforms like TikTok for mental health discussions. This study examined the accuracy of ADHD-related content on the platform, focusing specifically on alignment with DSM-5 diagnostic criteria. A total of 100 publicly available videos under the search term "ADHD" were analyzed using content analysis to assess creator characteristics, content types, and clinical accuracy. The findings revealed that while most videos referenced ADHD symptoms, only 46% of symptom portrayals aligned with DSM-5 criteria, and contextual diagnostic details were largely absent. Influencer-created content dominated the sample, with minimal representation from mental health professionals. Notably, even among professional creators, inaccuracies were present. These results highlight the gap between popular representations of ADHD and clinical standards, raising concerns about potential misinformation and self-diagnosis. The study underscores the need for improved platform policies, clinician awareness, and public education to promote accurate, DSM-5-aligned mental health information online.
