What this covers
- Attention and activity patterns
- The six ASRS screening items scored with their published item-specific thresholds.
Who it is for
Adults aged 18 or older who want to reflect on attention, organization, task initiation and activity patterns during the past six months.
What your result can show
The score counts how many of the six responses reach the ASRS scoring threshold. Four or more is the published screening threshold and only suggests that a fuller clinical evaluation may be useful.
Important limitations
The ASRS cannot confirm or rule out ADHD. Stress, sleep, mood, health, substances and other circumstances can affect the same experiences; developmental history and impairment require clinical evaluation.
A higher score does not establish a diagnosis. A lower score does not show that a condition is absent.
