Objective: The aim of the present study was to explore the prevalence of ADHD symptoms in a community sample of children in the United Kingdom. Method: There were 964 ten year olds (55% boys; M = 10.4 years; SD = 0.6) from mainstream schools in the United Kingdom in this study. The ADHD Rating Scale-IV, which provides ratings on the frequency of ADHD symptoms drawn from "DSM-IV" criteria, was administered to class teachers. Results: The findings indicated an overall 8% prevalence rate, with the majority of children identified as the Hyperactive/Impulsive subtype (5%). Almost half of these children were receiving additional support in the classroom as a result of learning difficulties. Conclusion: It is therefore of value for educators to be able to conduct early screening to support these children before problems worsen. (Contains 3 tables.)
