Note. Ratings occurred on a 0 to 5 scale (see text for anchors). The total number of children high on the ADHD-IN or ADHD-HI dimensions (i.e., 158, 132, and 166 for mothers, fathers, and teachers, respectively) is higher than the number of children in the ADHD group (i.e., 126, 108, and 135 for mothers, fathers, and teachers, respectively, see Tables 2 and 3) because some children had elevations on both ADHD-IN and ADHD-HI dimensions (i.e., ADHD combined presentation) and were therefore counted only once when creating the ADHD clinical group.
