Abstract
This meta-analysis evaluates the effectiveness of augmentative and alternative communication (AAC) for children with autism. AAC interventions that are effective in general and in yielding specific outcomes (e.g., language acquisition, replacement of challenging behavior, etc.) are outlined. Preliminary results are discussed in terms of their relevance for evidence-based practice in providing AAC services to individuals with autism. Directions for future research are posed based on identified research and methodological gaps in the experimental literature.
