Previous research has shown that parent implemented intervention is effective in increasing the speech and language development of children with cleft lip and palate. To further determine the efficacy of this intervention, this study compared the speech and language development of children with CLP, who received parent implemented intervention, with a group of younger, typically developing children, matched for vocabulary size. This study also evaluated the language differences between the mothers of both groups of children. Speech and language assessments were administered to the typically developing children and their mothers at two times to mirror the time of assessment for the children with clefts who received a three-month intervention, in a prior study. The findings revealed that both groups of children demonstrated the same amount of speech and language growth as well as the cleft group exhibiting a decrease in compensatory articulation errors.
