Abstract

Objective Although the literature documents that attention-deficit/hyperactivity disorder (ADHD) commonly onsets prior to age 6, little is known about the disorder in preschool children. We evaluated the clinical characteristics, psychiatric comorbidity, and functioning of preschool children and school-age youths with ADHD referred to a pediatric psychiatric clinic for evaluation. Method Structured psychiatric interviews assessing lifetime psychopathology by DSM-III-R criteria were completed with parents about their children. Family, social, and overall functioning were also assessed at intake. Results We identified 165 children with ADHD aged 4 to 6 years (preschool children) and 381 youths aged 7 to 9 years (school-age) with ADHD. Despite being younger, preschool children had similar rates of comorbid psychopathology compared with school-age youths with ADHD. There was an earlier onset of ADHD and co-occurring psychopathology in the preschool children compared to school-age youths. Both preschool children and school-age youths had substantial impairment in school, social, and overall functioning. Conclusions The results of this study suggest that despite being significantly younger, clinically referred preschool children with ADHD are reminiscent of school-age youths with ADHD in the quality of ADHD, high rates of comorbid psychopathology, and impaired functioning. Follow-up of these clinically referred preschool children with ADHD to evaluate the stability of their diagnoses, treatment response, and their long-term outcome are necessary.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
