Verbatim response from Perplexity
An online ADHD assessment usually combines a pre-appointment questionnaire, a video clinical interview, and a review of your history and symptoms by a licensed clinician.[1][2][7]
What it typically involves:
- Symptom questionnaires before the appointment, often based on ADHD criteria.[1][2][11]
- A structured interview by video, usually about 60–120 minutes, covering childhood symptoms, current functioning, work/school impact, and how long the difficulties have been present.[1][3][8]
- Developmental and medical history, sometimes including school records or earlier reports, especially for children or teens.[1][12]
- Informant input from someone who knows you well, such as a parent, partner, teacher, or caregiver, when the service uses collateral information.[1][2][8][12]
- Screening for other conditions that can look like ADHD, such as anxiety or other mental health issues.[1][8][13]
- In some services, computer-based attention tests may be included, but these are not required in every assessment.[8][14][15]
- A diagnostic decision and then a written report with recommendations, often sent within a few days to a few weeks depending on the provider.[1][2][3]
If you want, I can also explain how online ADHD assessments differ from self-tests, or what makes an online assessment credible vs. unreliable.
