Which therapy language helps bilingual children with developmental language disorder

The relationship between child language proficiency and language of treatment on the outcomes of bilingual children with developmental language disorder

NIH-funded research University of Houston · NIH-11324265

Speech therapy in English, Spanish, or both will be compared to see which approach best helps bilingual children with developmental language disorder based on their language strengths.

What this research studies

If your child speaks both Spanish and English and has trouble learning language, this work compares giving therapy in one language versus the other or in both to see how each approach affects progress. Children will be grouped by their current proficiency in each language and will receive targeted therapy while clinicians measure changes in both Spanish and English. The team will look for evidence that skills learned in one language transfer to the other and will use standardized language tests and observations over time. Results aim to give clearer guidance to families and speech-language therapists about which language(s) to use in treatment.

Who could benefit from this research

Good fit: Ideal candidates are Spanish-English bilingual children in the preschool to early school-age range who have a diagnosis of developmental language disorder and limited confounding conditions like hearing loss or intellectual disability.

Not a fit: Children who are monolingual, or whose speech difficulties are due to autism, hearing impairment, or intellectual disability rather than developmental language disorder, are unlikely to benefit directly from this work.

Why it matters

Potential benefit: If successful, the project could show which therapy language(s) lead to bigger language gains for bilingual children, helping therapists choose more effective treatments.

How similar studies have performed: Research has shown some cross-language transfer in experimental tasks, but direct clinical comparisons of therapy language for bilingual children with developmental language disorder are limited.
