The Relationship Between Child Language Proficiency and Language of Treatment on the Outcomes of Bilingual Children With Developmental Language Disorder
Developmental Language Disorder, Language Impairment
About this trial
This is an interventional treatment trial for Developmental Language Disorder focused on measuring developmental language disorder, bilingual children, sentence recast, Bilingual proficiency, Language transfer
Eligibility Criteria
Inclusion Criteria: parent concerns and/or a history of receiving services in the public schools age-specific cutoffs for the morphosyntax subtests for their best language (English or Spanish) on the Bilingual English Spanish Assessment. The cut-off score for best language for 4-year-olds is 84, for 5-year-olds is 85, and for 6-year-olds is 81. Using the best-language approach, these scores have a sensitivity over 90% and specificity over 80% for children between 4;0 and 6;11 years of age , which is considered acceptable for studies of diagnostic accuracy. nonverbal IQ, as measured by the Kaufman Brief Intelligence Test-2, matrices subtest, will be at or above a standard score of 70. pass a hearing screening test participants must be bilingual, that is children must be producing at least simple sentences in spontaneous speech in both Spanish and English participants must be able to benefit from treatment for both conditional adverbial clauses and complement clauses, as evidenced by accuracy below 40% on 10-item elicited production probes in both languages Exclusion Criteria: 1) children with significant sensory-motor concerns or psychiatric disorders per parent report will not be enrolled.

sentence recast - Bilingual (Spanish+English) intervention
A trained, bilingual SLP will treat the targeted structure at a rate of ~ 1 recast per minute, for 16 hours spread over 9 weeks to obtain a planned dose of 912-1008 recasts (960 +/- 5%). Following evidence on enhanced conversational recasting, the SLP will obtain the child's attention before recasting and systematically vary the lexical items in the recasts. Children receiving monolingual Spanish therapy will have the entire treatment session conducted in Spanish.

Children receiving monolingual English therapy will have the entire treatment session conducted in English.
Treatment will differ from monolingual therapy in that the child will be seen by two SLPs in keeping with one-person one-language models. This allows us to ensure that the dose in each language is controlled and supports the use of both languages evenly in therapy. Sessions will alternate between English-only therapy and Spanish-only therapy - thus the child will receive 8 hours of therapy treating the selected target in English and 8 hours treating the selected target in Spanish. A child in bilingual therapy will receive approximately 456-504 (480 +/- 5%) recasts in each language for a total of 912-1008 recasts combined.
