Common questions
Who is this ADHD test for?
This page is for adults 18 and older who have not already been diagnosed with ADHD and want a structured, evidence-informed place to start. ADHD is common, and plenty of people spend years feeling scattered or behind without knowing why. A short screen can help you name patterns worth discussing with a clinician.
How accurate are online ADHD tests?
Tools like the WHO Adult ADHD Self-Report Scale have real validation research behind them (for example Kessler et al., 2005). How well any screen performs still depends on the group studied and the cutoff used. Treat your result as something to bring to a qualified professional, not proof of ADHD.
How long does an ADHD test take?
This assessment has 12 questions. Most people finish in about three to five minutes. You see one question at a time so it is easier to stay focused. Your score appears as soon as you are done.
How much does an ADHD test cost?
In-person evaluations often run from a few hundred to a couple thousand dollars, depending on the provider and insurance. This first-step screen on our site is free so you can explore without paying upfront.
What is DSM-5?
DSM-5 is the manual clinicians use for official symptom criteria for ADHD and other conditions. We label questions with (DSM-5*) so you can see how they connect to that framework.
Is this a diagnosis?
No. This is a self-report screen, not a clinical interview. Only a licensed professional can diagnose ADHD after reviewing your history, rule-outs, and how symptoms affect your life.
Who created the reference scales?
The underlying screening approach comes from work with the World Health Organization and academic partners and is widely used in research and care. We list sources at the bottom of this section.
Next steps after your results
- When you talk with a clinician, a few concrete examples from work, home, or relationships matter as much as a screen score. Jot them down beforehand if that helps.
- If your score suggests ADHD may be worth exploring, consider booking a full evaluation.
- Whatever your score, small changes to sleep, movement, and routines still help many people.
