Treatment efficacy: functional phonological disorders in children.

This report addresses the efficacy of treatment for functional phonological disorders in children. The definition of phonological disorders and their incidence and prevalence are first presented. The impact of this disorder on the lives of children and the role that speech-language pathologists play in treating this disorder are then discussed. Evidence of the positive outcome of phonological treatment is reviewed, with particular emphasis on treatment procedures that have been deemed effective, the specific effects of these treatments on improving intelligibility, and comparisons between treatments in facilitating improved sound production.
