Preview of the 26 questions
Scoring & interpretation
Each item is rated on a scale from 0 (Not at all) to 3 (Very much). The items are grouped into three subscales: Inattention (items 1 to 9), Hyperactivity/Impulsivity (items 10 to 18), and Oppositional Defiant Disorder (items 19 to 26). The score for each subscale is the sum of its items and is compared with clinical cutoffs (mild, moderate, severe) to guide screening.
