The short answer
The Adult ADHD Self-Report Scale (ASRS v1.1) is a screening questionnaire developed with the World Health Organization. Answering 4 or more of the first 6 questions in the shaded range suggests symptoms consistent with adult ADHD and a full evaluation is worth considering. It cannot diagnose ADHD on its own.

About the ASRS
How the screener works
Each question has a threshold. For questions 1 to 3, answers of Sometimes or more count toward the score; for questions 4 to 6, answers of Often or more count. Four or more answers at or above the threshold are highly consistent with adult ADHD and warrant a full evaluation. The screener is not a diagnosis.
Teens 13 to 17 should be evaluated directly, with a parent or guardian involved.
