Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of the study is to examine the effects of teaching parents to use language support strategies on language skills in toddlers with language delays. We hypothesize that children whose parents who learn to use language support strategies at home will have greater language skills than those children whose parents do not learn the strategies.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The goal of the proposed project is to conduct an efficacy trial to determine whether Enhanced Milieu Teaching (EMT) significantly improves language deficits in young children at high risk for persistent language delays. The target population is children ages 24 -36 months who exhibit significant co-occurring delays in productive and receptive language skills, who have cognitive skills within the range of normal development, and who do not have other identified disabilities. An empirically based and manualized language intervention, Enhanced Milieu Teaching (EMT), implemented by therapists and parents will be compared to community based "business as usual" services in a randomized experiment enrolling 120 children and their parents. Children assigned to the EMT group will receive 24, 1-hour sessions of direct intervention at home that will include teaching their parents to implement EMT procedures across activities. Children will be assessed at 4 time points (before and after intervention, at 6 months and 12 months post-intervention) allowing the description and comparison of individual language growth trajectories over a period of 18 months. In addition, we will examine the relation between language growth and emergent problems in behavior and social skill development to determine whether early language intervention can prevent these difficulties frequently associated with early language delays. Results from this study will determine the efficacy of parent-plus-therapist implemented EMT with a new population of children, provide evidence about the potential for preventing persistent language delays and secondary social effects of early language delays, and expand developmental theory linking persistent language delays to specific risk factors and behavioral outcomes. The results of this study will have specific policy implications related to early identification and the inclusion of young children with language delays as a target population for early intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Enhanced Milieu Teaching

Parents receive 28 intervention sessions in which they learn to use language support strategies with their children.

Children are assessed at baseline, 4 months after baseline, 10 months after baseline, and 16 months after baseline.

Group Type EXPERIMENTAL

Enhanced Milieu Teaching

Intervention Type BEHAVIORAL

Enhanced Milieu Teaching (EMT) is a conversation-based model of early language intervention that uses child interest and initiations as opportunities to model and prompt language use in everyday contexts.

Community Services

Children receive speech-language services in the community. Children are assessed at baseline, 4 months after baseline, 10 months after baseline, and 16 months after baseline.

Group Type NO_INTERVENTION

No interventions assigned to this group
