ASRS Adult ADHD Test — Part A Screening

What the ASRS Part A measures

Part A covers finishing tasks, organisation, remembering appointments, delay aversion, fidgeting, and feeling overly active — hallmark adult ADHD symptom patterns rated by frequency.

This screening is validated for adults aged 18 and over only.

Who should take this screening

Consider the ASRS if lifelong attention, organisation, or restlessness issues affect work or relationships — especially if symptoms were present before age 12 and persist in multiple settings. Validated for adults 18+ only.

How ASRS Part A scoring works

Official scoring uses binary flags per item (not a simple sum). Four or more flags is a positive screen — indicating consistency with ADHD symptoms worth clinical follow-up.

0–3 flagsNegative screen on Part A — symptoms less consistent with ADHD on this screener

4–6 flagsPositive screen — often worth assessment by a licensed professional; not a diagnosis
