Peer-mediated aided AAC modeling: a systematic review

Peer-mediated instruction and aided AAC modeling are evidence-based practices that have been combined to support the communication skills of individuals using augmentative and alternative communication, but previous reviews and analyses have not yet synthesized studies examining school-based peer-mediated aided AAC modeling. A systematic review of the research yielded seven included studies that were evaluated for participant characteristics, peer training characteristics, intervention characteristics, communication outcomes, and quality measures. The results of this review revealed that the practice is implemented in mostly inclusive, nonacademic settings with minimal diversity in the population of students who participated in peer-mediated aided AAC modeling interventions and a limited scope of communication outcomes. The findings of the review provide direction for future research and implications for practice in the school setting.
