ASRS v1.1: Adult ADHD Self‑Report Scale

Part A 6-item screener · Harvard HCP 2024 scoring update

This self‑assessment helps screen for symptoms of ADHD in adults. Your answers stay on this page and are not stored or sent anywhere.

ASRS v1.1 — Part A (6-item screener)
Select the option that best describes your experience over the past 6 months. Your responses stay on this page and are not saved or sent anywhere.

This is a screening tool, not a diagnosis. Only a licensed clinician can diagnose ADHD. ADHD presents differently from person to person, and conditions such as trauma can produce overlapping symptoms — please use the result as a starting point for conversation, not a conclusion.

  1. 1. How often do you have trouble wrapping up the final details of a project, once the challenging parts have been done?
  2. 2. How often do you have difficulty getting things in order when you have to do a task that requires organization?
  3. 3. How often do you have problems remembering appointments or obligations?
  4. 4. When you have a task that requires a lot of thought, how often do you avoid or delay getting started?
  5. 5. How often do you fidget or squirm with your hands or feet when you have to sit down for a long time?
  6. 6. How often do you feel overly active and compelled to do things, like you were driven by a motor?
Max score: 24. Typical cutoff: 14+

This is a screening tool, not a diagnosis. Only a licensed clinician can diagnose ADHD.

How to answer

For each question, choose how often you experienced the behavior in the past 6 months: Never (0), Rarely (1), Sometimes (2), Often (3), Very Often (4).

Scoring methodology

This page implements the Harvard HCP February 2024 scoring updatefor ASRS v1.1 — not the original 0–6 dichotomous “shaded box” rule, which produced inconsistent prevalence estimates. Each answer scores 0 (Never) to 4 (Very Often) and the six items sum to a 0–24 total. A score of 14 or higher screens positive for ADHD.

Results fall into one of four strata: 0–9 low negative, 10–13 high negative, 14–17 low positive, 18–24 high positive. A positive screen is not a diagnosis — only a licensed clinician can diagnose ADHD.
