The overall purpose of this project is to improve how 5 to 7 year old children who have trouble using language use complex sentences. The questions that this study is trying to answer are: Does this treatment help children use sentences with adverbial clauses (e.g., sentences with because, so that, when, until, etc.)? Do children maintain this learning over time?
This study will involve 5-7 year old children with Developmental Language Disorder. The study will teach complex sentences with adverbial clauses (e.g., sentences with conjunctions like because, so that, when, until, etc.). The study will involve an initial assessment of children's language skills. Children who qualify for the project will participate in 20 teletherapy treatment sessions across approximately 10 weeks. The treatment will involve listening to stories that include several sentences with adverbial clauses, and answering questions about the stories. Following the treatment, children will participate in post-treatment testing of their learning.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Behavioral treatment
Behavioral: Recast therapy
Children will listen to examples of adverbial clauses in stories and generate sentences containing these clauses, then hear clinician recasts of their sentences

Time frame: Task is completed before each of 20 treatment sessions, starting with treatment session 1, over approximately 10 weeks.

Started Jul 2026 (actual). Primary completion is estimated for Jul 2028, 24 months after the start.
Of 73 non-industry interventional studies with no phase under Language Development Disorders, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 57. This study's planned 24 months is below that.
Counting every sponsor, half of 73 studies reached it within 30 months; a quarter within 19 and three quarters within 57.
