About This Quiz
This ADD and ADHD self-assessment is based on the Adult ADHD Self-Report Scale version 1.1 (ASRS v1.1), the most widely used and validated screening tool for adult ADHD in the world. The ASRS v1.1 was developed through a collaboration between the World Health Organization (WHO) and researchers at Harvard Medical School, and is grounded in the diagnostic criteria of the DSM-IV-TR (with strong alignment to DSM-5 criteria).
The scale consists of 18 questions divided into two parts. Part A contains the 6 questions found to be most predictive of an ADHD diagnosis in adults — these form the core ASRS Screener used in clinical settings. Part B contains 12 additional questions that provide a more complete picture of the inattentive and hyperactive-impulsive symptom domains.
Scoring uses the updated 0-24 scale published by Harvard Medical School in February 2024. Each response is weighted: Never = 0, Rarely = 1, Sometimes = 2, Often = 3, Very Often = 4. Part A scores are classified into four tiers: 0-9 (Low Negative), 10-13 (High Negative), 14-17 (Low Positive), and 18-24 (High Positive). A score of 14 or higher on Part A is considered a positive screen for adult ADHD.
Important: This quiz is a screening tool, not a diagnostic instrument. A positive screen means that your symptoms are consistent with adult ADHD at a level that warrants a professional evaluation — it does not mean you have ADHD. Other conditions, including anxiety, depression, sleep disorders, and PTSD, can produce similar symptoms. Only a qualified clinician can make a formal diagnosis.
