Administering and evaluating the results of the adult ADHD Self-Report Scale (ASRS) in adolescents.

Attention-deficit/hyperactivity disorder (ADHD) is a common condition that can be difficult to diagnose in adolescents, since symptoms may vary among patients, evolve over time, and mimic symptoms of other disorders. Various rating scales are helpful to the clinician when evaluating patients for ADHD and should be used as part of a thorough assessment. Clinicians should use both informant- and self-report rating scales to gather as much information as possible, while being aware that informants are subject to rater error and adolescents typically underreport symptoms. Rating scales can establish a baseline measure of the patient's symptom type and frequency, provide a framework for assessing symptom impairment, and aid clinicians in monitoring treatment response. The Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist is a reliable self-report rating scale for adolescents as well as adults.
