The World Health Organization Adult ADHD Self-Report Scale. Part A is the 6-question screener used by GPs and psychologists worldwide as a first step in assessing ADHD in adults.
Important: This is a screening tool, not a diagnostic test. ADHD diagnosis in adults requires a comprehensive assessment by a psychiatrist or psychologist with ADHD expertise. If your results suggest ADHD may be present, speak with your GP about a referral. In a crisis, call Lifeline 13 11 14.
| Score (of 6) | What it suggests |
|---|---|
| 0–3 | Low likelihood — ADHD symptoms are unlikely to be clinically significant based on this screen alone |
| 4–6 | Symptoms consistent with adult ADHD — a comprehensive specialist assessment is recommended |

How often do you have difficulty concentrating on what people say to you, even when they are speaking to you directly?
Assesses inattention during direct conversation - a core ADHD symptom.
How often do you leave your seat in meetings or other situations in which you are expected to remain seated?
Assesses hyperactivity - the restlessness that makes sitting still feel uncomfortable.
How often do you have difficulty unwinding and relaxing when you have time to yourself?
The ADHD brain often cannot switch off. This is not anxiety - it is a different kind of restlessness.
When you are in a conversation, how often do you find yourself finishing the sentences of the people you are talking to before they can finish them themselves?
Assesses impulsivity - the brain processes faster than social norms allow.
How often do you put things off until the last minute?
Higher threshold here - procrastination is common, so only frequent instances are flagged. ADHD procrastination is driven by executive function, not laziness.
How often do you depend on others to keep your life in order and attend to details?
Executive function difficulties mean organising daily life can feel impossibly hard. Also has a higher threshold.
