Notes. PA = physical activity; SC = sedentary classroom-based; HI = hyperactivity/impulsivity; IA = inattention; Opp. = oppositional.

Data for one participant at pre-testing were missing on teacher PMC subscales; thus, ns for typically developing SC participants on oppositional symptoms, moodiness, peer behavior and peer reputation subscales are 52.
