Experimental: 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.
Behavioral: Enhanced Milieu Teaching
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.
No Intervention: 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.
- Language Skills at 4 Months After Baseline as Measured by the Pre-school Language Scale - 4th Edition [ Time Frame: 4 months ]
Pre-school Language Scale - 4th Edition (a norm-referenced measure of receptive and expressive language) This scale measures the child's expressive and receptive language by going through a standard protocol of items, beginning based on the child's age, requiring a Basal of 3 consecutive correct responses and a Ceiling of 6 consecutive incorrect responses.
A higher score is considered better. A standard score of 100 is considered average for the child's age with scores ranging from 50-150.
- Expressive Vocabulary at 4 Months After Baseline [ Time Frame: 4 months ]Number of different words the child says during a 20-minute language sample.
