Abstract: Study reviewed the augmentative and alternative communication (AAC) intervention research involving adolescents and adults with a diagnosis of autism spectrum disorder (ASD). A systematic search of four electronic databases was conducted to identify and evaluate relevant research. A total of 16 publications containing 18 distinctive intervention studies were ultimately included in the review. All studies identified for inclusion utilized single-subject methodology. Nineteen unique adolescents and adults with ASD participated in the included studies. Picture symbols were used as representation in most (12 of 18) studies, making them the most frequently employed representation option. Grid displays were used to organize AAC messages in nine of the 18 studies. Six different instructional strategies have been implemented in AAC intervention studies for adolescents and adults with ASD: unspecified instruction, prompting, responding, video modeling, communication support strategies, and partner strategy instruction. Prompting was the most common strategy implemented. Most of the studies focused on the expression of wants and needs. Overall, the findings indicate that AAC interventions are highly effective for adolescents and adults with ASD. However, the limited number of adolescents and adults with ASD who have participated in AAC intervention research to date tempers these findings; more research is urgently needed. Future research focused on supporting communicative functions other than requesting (e.g., social closeness, information transfer) while participating in contexts important to the lives of adolescents and adults may be particularly valuable.
