Evaluation of an intervention program: relation between children's phonology and parents' communicative behavior.

Parents of 9 preschoolers with Down syndrome participated in a training program focusing on phonological skills. Three of the children were producing multiword utterances, but their speech was characterized by jargon and/or inconsistent errors. The remaining 6 children had very few spoken words or were mute; some relied on a Makaton sign vocabulary. Parents attended twelve 3-hour training sessions. Videotapes of parent-child interactions (made before, during, and after the program) were analyzed for number and type of children's phonological errors and rating of parents' therapeutic skills. Results showed that measures of the children's phonological abilities were correlated with their parents' interactional communication skills.
