This self-assessment asks how often you experience the 18 symptoms clinicians look at when evaluating adult ADHD, split into inattention and hyperactivity-impulsivity.
How the ADHD self-assessment works
You rate how often each experience applies to you over the last six months. Answers of “often” or “very often” count toward each symptom cluster, mirroring how clinicians structure an evaluation.
The three ADHD presentations
ADHD can be predominantly inattentive, predominantly hyperactive-impulsive, or combined. Your results show where your answers cluster so you can have a better-informed conversation with a professional.
This is not a diagnosis
Only a qualified clinician can diagnose ADHD. Use your results as a starting point — many people bring them to their GP or psychiatrist.
Frequently asked questions
Can an online test diagnose ADHD?
No. This is an educational self-assessment. A diagnosis requires a clinical evaluation that considers your history and rules out other explanations.
How long does it take?
About 5 minutes for 18 questions.
What do I do with my results?
If your results suggest elevated symptoms, consider sharing your report with a doctor or mental health professional.
