Objective: To provide an in-depth examination of whether pragmatic, expressive, receptive, and narrative language are associated with the social and academic functioning of children with ADHD. Method: Children with ADHD (n = 46) and neurotypical comparison (NC) children (n = 40) aged 7 to 11 years completed tasks measuring expressive, receptive, and narrative language, while parents rated pragmatic language and social- and academic functioning. Results: Children with ADHD differed significantly from NC children on pragmatic language, expressive language, receptive language, and narrative coherence. An examination of indirect effects revealed that a significant proportion of the association between ADHD and social functioning was shared with pragmatic language, while a significant proportion of the association between ADHD and academic difficulties was shared with pragmatic language as well as with expressive language. Conclusion: This preliminary study supports the clinical relevance of language in relation to the academic- and social functioning of children with ADHD. (J. of Att. Dis. 2024; 28(12) 1542-1554)
