Who and where the evidence may apply
Evidence comes from particular studies and language versions, so its relevance can vary.
- Intended audience
- Adults reflecting on attention, organization, task initiation and activity patterns over the past six months.
- Language version shown
- English (en) · Base wording used by this NuraCheck implementation
- Study participants and settings
- The cited calibration used 154 respondents drawn from the US National Comorbidity Survey Replication and compared the self-report scale with clinical reappraisal. It is US adult evidence from a small subsample, not a stand-alone diagnostic validation for every country or language.
Review the study used for these details
Scores do not capture culture, minority stress, disability or barriers to support. These factors can shape responses.
The evidence cannot determine whether a questionnaire fits you personally. NuraCheck does not ask for or infer identity to decide this.

What this questionnaire cannot answer
Stress, sleep, mood, health, substances and other circumstances can affect these experiences. The ASRS cannot confirm or rule out ADHD; developmental history and daily impact need clinical evaluation.
What your result can show
The score counts how many answers reach item-specific thresholds. Four or more reaches the published screening threshold and may support a fuller clinical evaluation.
Important limitations
Stress, sleep, mood, health, substances and other circumstances can affect these experiences. The ASRS cannot confirm or rule out ADHD; developmental history and daily impact need clinical evaluation.
