A self-screening reference, not a diagnosis
ADHD Self-Test shows how your answers to the six-question ASRS v1.1 Screener compare with the screener's published cut-off. A screener can point to a reason to talk with a professional. It cannot tell you whether you have ADHD, and it does not replace an evaluation by a qualified health care professional. As the screener's licensor puts it, diagnosis or prescription should never be made solely on the basis of a score from the screener.
- A result of 4 or more is not a diagnosis. Other conditions can lead to similar answers, which is why a clinician also checks your mood and medical history.
- A result below 4 does not rule ADHD out. In the original study, the screener identified about 69% of adults who had ADHD (sensitivity 68.7%; Kessler et al., 2005), so some people with ADHD score below the cut-off.
- It looks at the past 6 months only. A clinician also considers childhood history, how much symptoms get in the way of daily life, and other possible explanations.

The strategy guide
The "ADHD-friendly strategy guide" shown after a result is not available yet. When it is, it will contain general self-help methods for planning and organizing. It will not be treatment, and it will not replace care from a health care professional.
