The Adult ADHD Self-Report Scale (ASRS) Symptom Checklist is a self-reported questionnaire used to assist in the diagnosis of adult ADHD. The PhenX Toolkit uses ASRS as its adult protocol for Attention-Deficit/Hyperactivity Disorder Symptoms.[1]


The ASRS was developed in conjunction with the World Health Organization (WHO), and the Workgroup on Adult ADHD which included researchers from New York University Medical School and Harvard Medical School. The ASRS has eighteen questions, which are consistent with the DSM-IV[2] criteria and address ADHD symptoms in adults. The six question ASRS Screener was later developed as a subset of the WHO's eighteen question ASRS. At least one study has found that the six question ASRS Screener outperformed the eighteen question ASRS in diagnosing ADHD in the general population.[3]

ASRS has been adapted to other languages including Spanish and Chinese.[4][5] Conducted research proved that the scale is a valid and useful tool for the screening of adult ADHD.[6] The ASRS was externally validated on approximately 60 adult patients, and showed high internal consistency and high concurrent validity with the physician-administered ADHD rating system.[6]


Each question can be answered on a five item Likert scale, based on a scale of frequency ranging from "Never" to "Very Often". Answers are scored as either positive or negative and the threshold is different for individual questions. Answers of "Never" and "Rarely" are always scored negative, answers of "Often and Very Often" are always scored positive, and answers of "Sometimes" are scored positively in only seven of the eighteen questions. Four or more positive answers in Part A is indicative of ADHD symptoms.
