Recast Therapy for Treating Syntax in Bilingual Children With Developmental Language Disorder: A Feasibility and Early Efficacy Study Examining the Role of Language of Intervention on Outcomes.

The purpose of this study is to examine the feasibility of the delivery of complex syntax recast therapy via telepractice to Spanish-English bilingual children and provide preliminary evidence of the efficacy of this approach. Fifteen bilingual children with developmental language disorders were stratified based on language proficiency and randomized to one of three treatment conditions: Spanish only ( Analyses included all participants. Treatment fidelity was high, and participant attendance was remarkable, indicating feasibility. Regarding efficacy, recast therapy led to group-level gains on treated syntactic structures that exceeded those observed for the untreated comparison structure. For the 11 children who received therapy in only one language, approximately equal gains were observed in both the treated and untreated languages for conditional adverbials. Preliminary evidence suggests that for highly overlapping structures like conditional adverbials, recast therapy is effective and leads to change in both of the child's languages. Larger studies are required to understand how language of administration and proficiency may affect outcomes. https://doi.org/10.23641/asha.23739996.
