Adult ADHD self-check: 18 questions from the WHO scale

Researchers at the World Health Organization and Harvard built the Adult ADHD Self-Report Scale (ASRS v1.1) from the 18 ADHD symptoms in the DSM. Answer for the past 6 months. You need about 5 minutes.

The scale screens for ADHD. Only a clinician can diagnose it or name its type. Your answers stay in this browser. Google Analytics gets the start, the finish, the result group and App Store taps.

Part A: the screener

The scale’s authors picked these six questions because they predict a clinical diagnosis best.

Question 1 of 18How often do you have trouble wrapping up the final details of a project, once the challenging parts have been done?
Question 2 of 18How often do you have difficulty getting things in order when you have to do a task that requires organization?
Question 3 of 18How often do you have problems remembering appointments or obligations?
Question 4 of 18When you have a task that requires a lot of thought, how often do you avoid or delay getting started?
Question 5 of 18How often do you fidget or squirm with your hands or feet when you have to sit down for a long time?
Question 6 of 18How often do you feel overly active and compelled to do things, like you were driven by a motor?

Part B: the other 12 symptoms

These answers add detail to your profile of attention and activity. The screener result does not use them.

Question 7 of 18How often do you make careless mistakes when you have to work on a boring or difficult project?
Question 8 of 18How often do you have difficulty keeping your attention when you are doing boring or repetitive work?
Question 9 of 18How often do you have difficulty concentrating on what people say to you, even when they are speaking to you directly?
Question 10 of 18How often do you misplace or have difficulty finding things at home or at work?
Question 11 of 18How often are you distracted by activity or noise around you?
Question 12 of 18How often do you leave your seat in meetings or other situations in which you are expected to remain seated?
Question 13 of 18How often do you feel restless or fidgety?
Question 14 of 18How often do you have difficulty unwinding and relaxing when you have time to yourself?
Question 15 of 18How often do you find yourself talking too much when you are in social situations?
Question 16 of 18When you’re in a conversation, how often do you find yourself finishing the sentences of the people you are talking to, before they can finish them themselves?
Question 17 of 18How often do you have difficulty waiting your turn in situations when turn taking is required?
Question 18 of 18How often do you interrupt others when they are busy?

How the scoring works

Each question has a cut-off. Questions 1, 2, 3, 9, 12, 16 and 18 count from Sometimes. The other eleven count from Often.

counted

The screener result uses Part A only: four or more counted answers out of six match the pattern the WHO scoring looks for. The profile uses all 18 and splits them into the two DSM-5 groups, nine questions each.
