Six questions from the ASRS v1.1
Before the tasks you answer Part A of the Adult ADHD Self-Report Scale (ASRS v1.1), the six-item screener developed with the World Health Organization. Each question asks how often something has happened over the past six months.
The check uses the official wording. Your answers sit alongside your task results as indicators, not a diagnosis.

A check, not a diagnosis
The check shows how you did on four attention tasks and six questions. It cannot diagnose ADHD or replace a full clinical assessment. If your results concern you, discuss them with a clinician.
Questions
Do I need an account?
Yes, after the first task. Create a free account to continue; it keeps your results.
How long does it take?
About 20 minutes: six questions, then four short tasks. You can pause between tasks.
Can it diagnose ADHD?
No. A qualified clinician diagnoses ADHD from a full history, information across settings and other possible explanations. The check gives you indicators to bring to that conversation.
Do I have ADHD?
An online test cannot answer that. The check shows how you answered six questions about everyday attention and how you did on four tasks. These are indicators to bring to a clinician; only a qualified clinician can say whether ADHD explains what you notice, after a full assessment.
Is an online ADHD test accurate?
It records your answers and how you did on each task in one sitting. That is useful context, not a diagnosis: sleep, stress, the device and distractions can change task results, and questionnaire answers depend on how you see your own experience. Treat the results as indicators.
How is adult ADHD diagnosed?
A qualified clinician takes a full developmental and psychiatric history, looks for symptoms that began in childhood and show up in more than one setting, checks their impact on daily life and considers other explanations. Rating scales such as the ASRS can support that assessment; no single questionnaire or task is enough on its own.
Is the ADHD test different for women?
No. The questions and tasks are the same for everyone. NICE guidance notes that ADHD is thought to be under-recognised in girls and women, who are less likely to be referred for assessment. If that sounds familiar, bring concrete everyday examples to a clinician.
What is the ASRS?
The Adult ADHD Self-Report Scale (ASRS v1.1) was developed with the World Health Organization. Part A is its six-item screener: each question asks how often something has happened over the past six months. The check uses those six questions in their official wording. The answers are indicators, not a diagnosis.
Is there a longer version?
Yes. The ADHD Screening covers more tasks on attention, speed, memory and reasoning. Find it on the tests page.

What ADHD is and how adults are diagnosed
ADHD is defined by a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development. Symptoms begin in childhood, occur in more than one setting, and are not better explained by another condition. In adults, hyperactivity may appear as restlessness, while inattention and impulsivity can affect organization, task completion, and relationships.
A qualified clinician diagnoses ADHD using a full developmental and psychiatric history, evidence of impairment, information across settings, and consideration of coexisting or alternative conditions. Rating scales can support that assessment, but no single questionnaire, observation, or cognitive task is sufficient on its own.
A careful boundary. Sleep, mood, anxiety, medication, health, device conditions, and the testing environment can all affect performance. A browser task cannot determine why a result looks the way it does.
Signs considered in an adult assessment
Clinical assessment looks for persistent symptoms, functional impact, childhood onset, and a pattern across settings. Examples include:
- Sustaining attention. Difficulty staying with tasks or conversations, especially when they require sustained mental effort.
- Organization. Difficulty sequencing tasks, managing time, keeping materials in order, or finishing what was started.
- Forgetfulness. Frequently losing needed items or forgetting appointments and everyday responsibilities.
- Impulsivity. Interrupting, answering before a question is complete, or finding it difficult to wait.
- Restlessness. Feeling internally restless, fidgeting, or finding prolonged stillness difficult.
- Functional impact. Symptoms cause meaningful difficulty in work, education, relationships, or daily responsibilities.
These examples are educational, not a self-diagnosis. A clinician considers duration, onset, impairment, multiple settings, and other possible explanations.
