Summary: College students are increasingly turning to TikTok not only for entertainment but also as a source of information about health, including mental health conditions like attention-deficit/hyperactivity disorder (ADHD). A recent experimental study from Syracuse University shows that exposure to inaccurate TikTok content about ADHD reduced students’ factual knowledge while paradoxically increasing their confidence in that incorrect knowledge.
Students who viewed misleading content were more likely to express intent to pursue both evidence-based treatments and unproven interventions. The results highlight how persuasive social media narratives can shape public understanding and influence health-related decisions, sometimes with potentially harmful consequences.
Key Facts:
- Misinformation effect: Viewing false TikTok content decreased accurate knowledge about ADHD while raising confidence in that inaccurate understanding.
- Treatment intentions: Participants exposed to misleading content reported stronger intentions to seek both scientifically supported and non-evidence-based treatments.
- Entertainment matters: When participants perceived content as entertaining, they were more likely to accept the information and express treatment-seeking intentions.

TikTok is one of the fastest-growing social platforms globally, especially popular among college-age users.
In the United States, millions of adults use TikTok, and a large share falls within the college-age demographic. Many students use the app beyond casual viewing: roughly four in ten Americans now use TikTok as a place to look for information, blurring lines between entertainment and informal health education.
While TikTok can offer useful tips and peer support, users need to be cautious and critically evaluate health-related claims. Conditions like ADHD are complex, and misinformation can spread rapidly in short-form video formats that prioritize engagement over accuracy.
To better understand these dynamics, researchers in the Department of Psychology at Syracuse University designed an experimental study examining how college-aged students respond to accurate versus inaccurate ADHD information presented in a TikTok-like format.
Their findings, published in the journal European Child & Adolescent Psychiatry, indicate that exposure to ADHD misinformation on TikTok significantly undermines correct knowledge about the disorder while increasing misplaced confidence in that misinformation.
Lead author Ashley Schiros, a Ph.D. candidate in clinical psychology at Syracuse University, emphasized the public health implications. She warns that social media narratives that deviate from scientific evidence can reshape perceptions of ADHD in ways that hinder appropriate diagnosis and treatment.
“ADHD misinformation on social media risks creating inaccurate beliefs about symptoms and effective care,” Schiros said. “That can lead to unnecessary or misguided treatment-seeking, self-diagnosis, or barriers to seeking evidence-based services.”
A TikTok Test
Schiros and colleagues were motivated by clinical observations that many students arrive requesting assessments or therapy because they believe they have ADHD—beliefs often influenced by online content. To investigate, the researchers developed a controlled experiment using short-form content designed to resemble TikTok posts.
About 500 Syracuse University students participated. They were randomly assigned to view one of three types of short content: accurate information about ADHD, factually incorrect information, or neutral control material. The accurate content included clear statements about common ADHD symptoms, such as frequent difficulty completing assignments on time, trouble staying focused during lectures, and frequently misplacing important items.
The misinformation condition presented popular but inaccurate claims found online, including vague or colloquial concepts like “ADHD paralysis,” an over-generalized “urge to people please,” or a persistent sense of being overwhelmed by minor tasks—phrases that may sound persuasive but lack rigorous clinical definition.
Participants completed a baseline ADHD knowledge assessment before viewing the content and followed with measures evaluating their ADHD knowledge, stigma, and intentions to seek assessment or treatment after exposure.
Deciphering Real from Reel
The results showed a clear effect: students exposed to misinformation demonstrated significantly lower factual accuracy about ADHD, yet reported higher confidence in what they believed they knew. In other words, misinformation not only impaired knowledge but also strengthened certainty in those misconceptions.
Importantly, the misinformation group indicated greater interest in pursuing both evidence-based treatments (such as formal clinical assessment and behavioral or pharmacological interventions) and non-evidence-based approaches. Perception of the content as entertaining was associated with stronger belief in the information and greater intent to seek treatment.
Schiros noted that the consequences extend beyond ADHD: short-form social media can circulate misleading health and mental health advice widely, and entertaining or emotionally engaging presentations can make false claims feel credible.
“People who consume online content should be aware of how persuasive formats can amplify misinformation,” she said. “It’s important to cross-check claims with reliable sources and seek professional guidance when considering diagnosis or treatment.”
Fact-Checking the Feed
Addressing misinformation on platforms like TikTok is complex and likely requires efforts at multiple levels. The researchers recommend system-level strategies, including public health and academic institutions launching targeted campaigns to pre-bunk and correct common myths while producing accurate, engaging content.
Creator-focused interventions could also help: offering accessible tools and incentives for content creators to cite evidence and consult experts may improve the overall quality of health information available to viewers.
The research team plans follow-up work to examine participants’ naturalistic TikTok use and how real-world exposure to ADHD content relates to knowledge, stigma, and help-seeking behaviors. They also call for additional studies on how online content influences stigma and which corrective strategies are most effective.

Abstract
Misinformation mayhem: the effects of TikTok content on ADHD knowledge, stigma, and treatment-seeking intentions
Short-form ADHD content on TikTok is widely viewed by college students, yet misinformation about ADHD is common on the platform. This study used an experimental design to test how exposure to accurate versus inaccurate TikTok-style content affects ADHD knowledge, stigma, and intentions to seek treatment among treatment-naïve college students.
Following a pilot phase to develop representative stimuli, the main study randomly assigned 490 participants to view accurate ADHD information, ADHD misinformation, or neutral control content. Baseline ADHD knowledge was assessed before viewing; follow-up measures evaluated knowledge, perceived stigma, and treatment-seeking intentions after exposure.
Participants exposed to misinformation showed significantly lower accurate ADHD knowledge but greater confidence in their knowledge after viewing. Those who saw accurate content gained more correct knowledge and confidence. The misinformation group also reported higher intentions to pursue both evidence-based and non-evidence-based treatments. No significant differences in ADHD stigma emerged across conditions. Perceived entertainment value of the content correlated with both knowledge outcomes and treatment-seeking intentions.
Overall, TikTok ADHD misinformation reduced factual understanding while boosting confidence in incorrect beliefs and increasing interest in treatment—findings that underscore the potential harms of social media misinformation for individual decision-making and public health.
