Adult ADHD Self-Report Scale (ASRS) Symptom Checklist


World Health Organization - WHO




The Adult ADHD Self-Report Scale (ASRS) Symptom Checklist draws on the ADHD Diagnosis and Screening in Adults-Clinical assessment using DSM-5 criteria and the ASRS checklist. The ASRS symptom checklist was developed by the World Health Organization to correspond with the 18 symptoms included in the DSM-IV before it was replaced by the DSM-5 criteria in 2013. The grey and pink letters on the left side correspond with the DSM-5 criteria. Healthcare professional can use the ASRS as a tool to help screen for ADHD in adult patients. The questionnaire takes about fifteen minutes for patients to complete.

Formal assessment and diagnosis should only be made by appropriately qualified healthcare professionals, such as specialist psychiatrists, specialist nurse, or other qualified healthcare professionals, who have training and expertise in the diagnosis of ADHD.

The patient answers the questions, rating each of the criteria shown using the scale on the right side of the page. As they answer each question they should place an X in the box that best describes how they have felt and conducted themselves over the past 6 months.
