BACKGROUND: Up to 40% of children with the ADHD are suggested to have language difficulties. Other than language difficulties being debilitating in their own right, language difficulties in childhood ADHD are problematic because they likely enhance the social and academic difficulties often present in children with this disorder. Children with ADHD also appear to have narrative difficulties; i.e. they have problems telling a coherent, understandable story. Telling stories is a particularly interesting language task as the investigation of how children use their language in an unstructured task is similar to how they use their language in everyday interactions. However, the extent, causes, and clinical relevance of language and narrative difficulties in ADHD remain largely unknown. Studies are scarce and fraught with problems warranting investigations of language abilities in children with ADHD that measure language as well as executive function (EF) and that investigate the clinical relevance of these language difficulties. This is necessary in order to tease apart and gain knowledge of the association between language, EF and ADHD. Ultimately, such an investigation can inspire future assessment and treatment of language difficulties in children with ADHD. AIMS AND HYPOTHESES The first aim is to examine narrative abilities in children with ADHD. This is done by investigating whether children with and without ADHD differ with respect to their narratives. The second aim is to examine whether language, EF and/or ADHD symptoms can explain narrative function in children with and without ADHD. The third aim is to investigate which specific domains of language children with ADHD have the most difficulty within. The fourth aim is to investigate whether the language difficulties as well as the narrative difficulties identified are associated with academic and social function in ADHD. PARTICIPANTS AND PROCEDURES Up to 100 children with ADHD, age 7-11, consecutively referred from Aarhus University Hospital, Denmark, will be compared to up to 100 typically developing children, age 7-11, recruited from schools in the same community as the hospital. After initial screening by telephone, informed consent has been obtained from both custodians and verbal assent has been given by the child, all children (ADHD and control) will be assessed at two separate meetings at the University of Aarhus by a member of the project group. The parents will receive questionnaires about their child and if the families give their consent, questionnaires will also be sent to the children's primary teacher. The parents and teachers receive questionnaires about the child's behavior, language and social and academic abilities. All hypotheses will be investigated with appropriate statistical analyses. The role of IQ, parental educational level etc. is also examined in the analyses. If an adequate sample size is obtained, confirmatory factor analysis (CFA) will be applied to handle data, and if a factor solution is supported, factor scores will be included in all analyses, thereby reducing the number of variables in the analyses. REGISTRATION DETAILS The study record reported at clinical trials.gov is completely consistent with the protocol approved by the Central Region Committee on Health Research Ethics in Denmark. The study was registered at clinical trials.gov after enrollment had begun, but no changes have been made in any procedures, recruitment etc., and as such it was assessed to be feasible to include the few participants that had been enrolled before registration in clinical trials.
