What is an adult ADHD test?

An adult ADHD test is a simple questionnaire that helps you see whether your symptoms resemble common adult ADHD patterns. It looks across three areas: attention, activity level/restlessness, and impulsivity.

This 12‑question online screening is widely used as a quick first step and usually takes less than 5 minutes. It asks how often you experience challenges like losing focus, forgetting tasks, feeling restless, or starting many activities without finishing them.

Accuracy: peer‑reviewed studies on adult ADHD screening tools report sensitivity around 85–95% and specificity around 70–92%, depending on the population studied and the cutoffs used. These ranges mean screeners identify most people who may have ADHD while also limiting false positives.

Limits: even accurate online tests cannot confirm ADHD. Only a qualified clinician can diagnose ADHD after a full evaluation that reviews history since earlier life, daily impact across settings, and other possible explanations such as anxiety, depression, or sleep problems.

Next steps: if your results suggest ADHD, share them with a clinician who has adult ADHD experience. A proper evaluation includes a detailed interview, review of personal and work history, and assessment of functional impact, plus differential diagnosis.

While you wait: set phone reminders, break large tasks into smaller steps, use visual timers for focused work blocks, and keep a consistent sleep schedule.
