Abstract
Objective. The aim of this study was to explore whether children with attention deficit hyperactivity disorder (ADHD) have language and/or pragmatic difficulties compared to typically developing children. Methods. Nineteen children with ADHD (age 5–12 years) and nineteen typically developing children (age 5–8 years) were evaluated using the Finnish version of Children's Communication Checklist 2nd edition (CCC-2). The CCC-2 questionnaire was filled in by their parents. Results. According to the CCC-2 questionnaire, differences between the groups were found in linguistic abilities, pragmatics skills, and social interaction. Conclusion. According to the CCC-2 profiles, many children with ADHD may have various kinds of communication difficulties, even if they do not have a diagnosed language disorder.
