Multimethod Assessment of Attention, Executive Functions, and Motor Skills in Children With and Without ADHD: Children's Performance and Parents' Perceptions.

We examined whether children with attention-deficit/hyperactivity disorder (ADHD) differ from children without ADHD in attention, executive functions, and motor skills and whether measures of parents' perceptions and children's performance reveal comparable results. About 52 children with ADHD and 52 children without ADHD aged 6 to 13 years completed performance-based measures of attention, executive functions, and motor skills. Parents completed questionnaires to rate their children's skills. Parent questionnaires but not performance-based measures revealed higher inattention and lower executive function skills in children with ADHD compared to controls. For motor skills, both measurement methods revealed lower mean values and a higher number of children showing an impairment in the ADHD group. Parent-reported difficulties but not performance-based measures were related to the presence of an ADHD diagnosis. Our findings suggest that considering both parent questionnaires and performance-based measures will lead to a comprehensive picture of a child's strengths and difficulties.
