The ASRS v1.1 is a screening tool, not a diagnostic instrument. ADHD can only be diagnosed by a qualified professional through comprehensive clinical assessment. Many factors can contribute to attention and concentration difficulties, and a professional evaluation considers your full history and current circumstances.

About the ASRS v1.1

The Adult ADHD Self-Report Scale (ASRS v1.1) was developed by the World Health Organisation (WHO) in collaboration with Kessler et al. It is the most widely used screening instrument for adult ADHD worldwide. Part A (questions 1-6) serves as the primary screener, while Part B (questions 7-18) provides additional clinical information.

Inattention (questions 1-4, 7-11) — Difficulty sustaining attention, organising tasks, and following through
Hyperactivity (questions 5-6, 12-14) — Restlessness, fidgeting, and feeling driven
Impulsivity (questions 15-18) — Interrupting, difficulty waiting, and talking excessively

The ASRS is used clinically to identify adults who may have ADHD. A positive Part A screen is the most predictive component. The full 18-item scale provides additional detail across the three symptom domains.
