What is it about?

Developmental language disorder (DLD) diagnosed at age 4 or 5 tends to persist into adulthood, although the profile of language strengths and weaknesses is likely to change as the child develops. While the language profile of English-speaking adolescents with DLD has been studied, research for languages other than English is still needed. This paper examines where the strengths and weaknesses lie in the language of French-speaking adolescents with DLD.

Why is it important?

In contrast to English, there is still debate about whether grammatical deficits are a particular weakness in younger French children with DLD. By examining adolescents, our study provides evidence that grammatical deficits are an important weakness in French-speaking adolescents with DLD compared to other language domains, such as lexico-semantics.


For professionals working with Québec French teenagers, only a few standardized tests are available to assess developmental language disorder and some of them have been shown not to meet psychometric criteria. This study can be considered a first step in identifying language characteristics of French-speaking adolescents with DLD.
