Augmentative and alternative communication interventions are effective for adolescents and adults with autism spectrum disorder, but more work is needed

摘要

Design: Systematic review. Data sources: Studies included in this review were identified through electronic database searches (i.e. ERIC, PsychArticles, PsyclNFO, PubMed) and a hand search of the Journal of Autism and Developmental Disorders, The electronic search identified 249 articles for review, and the hand search of the journal identified two articles. Study selection and assessment: Studies were included in this review if they were published in English and were a peer-reviewed intervention study (including either single-case or group designs) published after 1995 that included an augmentative and alternative communication (AAC) intervention as an independent variable and included only participants with ASD 11 years of age or older. The authors used the Cochrane Handbook for Systematic Reviews of Interventions (Higgins & Green, 2011) to guide the development of their protocols. Using a coding protocol, they collected data on each study's design (i.e. group, type of single-case design), participant characteristics (e.g. age, gender, diagnoses), means of commu-nication/AAC (i.e. no tech, low tech, mid tech, high tech), intervention characteristics (i.e. how the communication response was taught - prompting, video modeling, instruction, etc.), dependent variable characteristics (i.e. communicative behavior, function of communication behavior, factor of disability addressed), results (described in the "Outcomes" section), and certainty of evidence.
