Twenty-five children (21 males, 4 females; mean age 4.8 years) with attention-deficit-hyperactivity disorder (ADHD) participated in this study in addition to 25 typically developing children (21 males, 4 females; mean age 4.9 years). Parental ratings of the preschool children and preschool child self-ratings were examined within the framework of three domains: behavioral disturbance, social competence, and familial environment. Compared to their typically developing peers, preschool children classified as having ADHD were rated by their parents as significantly more aggressive, more demanding of parental time, less socially skilled, less adaptable to change in routine, and as exhibiting more noncompliance. In contrast to these parental ratings, preschool children with ADHD perceived themselves as equally competent, and as socially accepted as their peers. Parents of preschool children with ADHD rated themselves as less competent parents, and as experiencing a restricted parenting role. Although parenting a preschool child with ADHD was viewed as stressful, the parents did not rate general family functioning to be adversely affected.
