Attention-Deficit/Hyperactivity Disorder in Preschool Children: An Investigation of Validation Based on Visual Attention Performance

摘要

Conclusions: Attentional impairments detected only in the 4-year-old age group suggest that DSM-IV ADHD criteria are useful and valid at this age. Study findings suggest modification to the DSM criteria may be needed for children younger than 4 and that further investigation of this issue using performance-based measures is now warranted.
