A series of widely used rating scales designed to measure symptoms and impairments associated with ADHD and related problems in children and adolescents. Administered to parents, teachers, and sometimes the individual themselves, it uses a Likert-type scale to rate specific behaviors over the past month. The results are interpreted using standardized T-scores, with higher scores indicating greater severity of symptoms, to aid in diagnosis and treatment monitoring.  

A standardized assessment used by clinicians to evaluate adults for ADHD, providing multi-informant perspectives (self-report and observer reports) to gauge the severity and nature of symptoms. The assessment is available in long, short, and screening versions, and it measures various behaviors like inattention/memory problems, hyperactivity/restlessness, impulsivity/emotional lability, and problems with self-concept. Its scores are compared to normative and ADHD reference samples to inform clinical diagnoses and treatment plans.
