About the ASRS v1.1
The Adult ADHD Self-Report Scale (ASRS v1.1) was developed by the World Health Organization (WHO) in collaboration with Dr. Ronald Kessler of Harvard Medical School. It is a validated 18-item screening instrument designed to help adults identify whether they may have symptoms consistent with ADHD. The first 6 questions (Part A) are the most predictive and are used as the primary screener. Parts A and B together provide a more complete symptom profile.
How Scoring Works
Each question is scored 0-4 based on symptom frequency. Part A (questions 1-6) is the primary screener — a score of 14 or higher on Part A suggests symptoms consistent with ADHD. The full 18-question score provides a more detailed picture. Higher scores indicate more symptoms, but severity and impairment must be assessed by a professional.
Who Should Take This Test?
This screening is designed for adults aged 18 and older who suspect they may have ADHD symptoms. It is especially relevant if you experience persistent difficulty with focus, organization, time management, impulsivity, or restlessness that impacts your daily life, work, or relationships.
Tips for Taking This Assessment
Answer each question honestly based on your real behavior and preferences, not what you think the ideal answer should be. Go with your first instinct rather than overthinking — spontaneous answers tend to be more accurate. Take the assessment in a quiet environment where you can focus without distractions. Remember that there are no right or wrong answers. Your results are meant to provide self-awareness and starting points for improvement, not definitive labels.
Frequently Asked Questions
Is this a real ADHD test?
This is the WHO Adult ADHD Self-Report Scale (ASRS v1.1), a clinically validated screening tool developed by the World Health Organization and Dr. Ronald Kessler of Harvard Medical School. It is the most widely used ADHD screening instrument worldwide. However, it is a screener, not a diagnostic test — only a professional can diagnose ADHD.
What score means I have ADHD?
A Part A score of 14 or higher (out of 24) suggests symptoms consistent with adult ADHD and indicates you should seek a professional evaluation. However, no score definitively confirms or rules out ADHD — diagnosis requires a comprehensive clinical assessment.
Is my data private?
Yes. Your answers are processed entirely in your browser. Nothing is sent to any server. We do not collect, store, or transmit your responses. When you close the page, your answers are gone.
Can I share results with my doctor?
Yes. Take a screenshot of your results to share with your healthcare provider. The ASRS is designed to be used as a conversation starter with clinicians and can help guide the diagnostic process.
What should I do if I score high?
Schedule an appointment with a psychiatrist, psychologist, or GP experienced in ADHD. Bring your screening results. A professional evaluation typically includes a clinical interview, symptom history, and may include additional assessments.
Does this test work for women and non-binary people?
The ASRS was validated across genders. However, ADHD often presents differently in women (more inattentive, less hyperactive), which can lead to underdiagnosis. If your symptoms affect your life, seek evaluation regardless of your score.
