Note: Means are unadjusted for the effects of the covariate. Comparison n = 86; ADHD n ranged from 177-178. The effect of the covariate was significant (p < .05) for the behavioral domain only. Higher mean scores indicate greater overestimation of competence by the child relative to teacher report.
