Psychiatric self-diagnosis
Do not assume the answer. Accuracy is an empirical quantity that likely differs by condition, age, symptom severity, access to healthcare, information source, and diagnostic complexity.
What we know
Young people already use the internet to understand symptoms and decide whether they have a problem. Stigma and access barriers are well documented. Some adult autism self-identification is described as recognition after missed care. Popular ADHD TikTok content is often misleading.
How we know it
Help-seeking reviews, qualitative studies, content analyses. Almost no blinded concordance studies of social-media-era self-labels versus structured interviews.
What else could explain it
Self-diagnosis as access workaround; as destigmatized disclosure; as interpretative inflation; as selection of the already symptomatic.
What we don't know yet
The concordance rate, its condition-specificity, and whether exposure to diagnostic content raises new self-diagnosis after baseline symptoms are controlled.
Motives are plural. Waitlists, cost, dismissal in clinic, and culturally unsafe services make unofficial conclusions rational. Mental-health literacy campaigns ask people to notice symptoms. Influencer checklists make noticing easy. Confirmation bias makes stopping hard. None of these facts tells us whether a given self-label is correct.
“This description resembles me” is symptom recognition. “I have X” is self-diagnosis. “X is who I am” is identity integration. Public argument often uses the last as if it were the first. This project keeps them on separate rungs.
Self-assessment quizzes, comment-section diagnoses, and short-form “signs you have…” videos are not clinical instruments. Yeung, Ng and Abi-Jaoude (2022) found that highly viewed ADHD TikTok videos frequently conflicted with guidelines. That is a finding about content. Viewer effects remain a different study.
Possible benefits: language for inchoate difficulty; community; a prompt to seek assessment; reduced shame. Possible risks: premature foreclosure of other explanations (sleep, trauma, anaemia, ordinary unhappiness, another diagnosis); delay of care; identity narrowing; iatrogenic attention to symptoms. Which dominate is not known in general, and almost certainly not the same for autism in missed adults and for complex, low-base-rate, highly media-shaped presentations.
Self-identification of autism after decades of being missed is not the same research object as an adolescent adopting a DID vocabulary from short-form video. Treating them as one “self-diagnosis epidemic” is a category error. See DID,condition-specific contagion notes, andclaims.
