Effects of AAC interventions on communication and language for young children with complex communication needs.

Children with complex communication needs (CCN) who require augmentative and alternative communication (AAC) are at considerable risk in many aspects of their development: (a) functional communication skills, (b) speech development, (c) language development, (d) cognitive/conceptual development, (e) literacy development, (f) social participation, (g) access to education, and (h) overall quality of life. Early intervention is critical to address these areas and provide successful and functional outcomes. AAC offers the potential to enhance communication, language, and learning for children with significant communication disabilities. This paper provides an overview of the effects of AAC interventions on communication, behavior, language, and speech outcomes for young children with CCN for pediatricians and other medical and rehabilitation professionals. Future research directions to maximize the communication development of young children with CCN are also discussed.
