ASRS-v1.1 — Adult ADHD Self-Report Scale

WHO 6-item screener (Part A) for adult ADHD (Kessler 2005). Each item rated 0–4 (never to very often). Items 1–3 score 2+ and items 4–6 score 3+ are clinically significant ('darkened-box scoring'). This calc returns simple sum 0–24 — ≥4 darkened-box items strongly suggests ADHD.

Q1. How often have you had trouble wrapping up the final details of a project once the challenging parts have been done?*

Q2. How often do you have difficulty getting things in order when you have to do a task that requires organisation?*

Q3. How often do you have problems remembering appointments or obligations?*

Q4. When you have a task that requires a lot of thought, how often do you avoid or delay getting started?*

Q5. How often do you fidget or squirm with your hands or feet when you have to sit down for a long time?*

Q6. How often do you feel overly active and compelled to do things, like you were driven by a motor?*

Score interpretation

Unlikely ADHD 0–8

→ Reassure. Address other causes of presenting symptoms (sleep disorder, depression, anxiety, substance use).

Possible ADHD 9–14

→ Use full ASRS (18 items) to characterise; consider DSM-5 / DIVA-5 structured interview. Refer to specialist adult ADHD service if persistent functional impairment per NICE NG87.

Highly likely ADHD 15–24

→ Specialist diagnostic assessment. If diagnosed: psychoeducation, CBT/coaching, occupational adjustments. Pharmacotherapy: methylphenidate / lisdexamfetamine first-line per NICE NG87; atomoxetine alternative. Address comorbidity (depression, anxiety, substance use).
