Percent of children who met criteria for ADHD in year 1 who exhibited dichotomized high impairment (i.e., an average score across all completed assessments in years 2–9 ≥ 1 SD from the sample mean in the direction of impairment) at each number of inattention (I) and hyperactivity-impulsivity symptoms for measures of impairment for which inattention symptoms were significantly more strongly related to impairment than hyperactivity-impulsivity symptoms (left panel) and vice-versa (right panel). Counts of 0-4 symptoms were collapsed because few children with ADHD had fewer than 4 symptoms of either dimension in year 1.
