The information from the People Magazine article claims that half of TikTok's Health video contains misimformation. People Magazine is an American magazine that focuses on pop culture events and entertainment news. People Magazine isn't an academic or scientific source. The author of the article is Cara Lynn Shultz, who is a People Magazine writer, editor, and pop culture specialist, but doesn't have expertise in mental health or conduct any research. Shultz mostly reports on issues, rather than conducting research.
People magazine claims that TikTok videos regarding mental health can be inaccurate, which could be potentially harmful because of the inaccuracies in the information in the videos. The claim is true, but the article is slightly misleading. The evidence of the article is from The Guardian, which is a British news outlet. "The outlet explains it came to this conclusion by taking the top 100 videos under that hashtag and sharing them with academic experts and mental health professionals for review." The article only looked at 100 popular videos on TikTok, which is a very small sample compared to the large platform that TikTok is, where thousands of people post videos.
The links referenced in the article are from The Guardian, theguardien.com/society/2025/may/31/more-than-half-of-top-100-mental-health-tiktoks-contain-misinformation-study finds, which is what the article is around. The National Library of Medicine agreed with the overall information from the article, but more research needs to be conducted to see the amount of misinformation about mental health on TikTok. When conducting research, a limitation was that sample sizes were small, which could cause inaccuracies. pmc.ncbi.nlm.nih.gov/articles/PMC9164092/#sec11. In another article by Healthline, they agreed with the information that reported: "52% of the top-performing ADHD videos and 41% of autism-related videos on TikTok contained information that was inaccurate or not supported by current clinical evidence." The article was fact-checked by a mental health specialist, giving more credibility to the claim of the misinformation from mental health videos on TikTok.
