The Effect of a Situation-based AAC Intervention Using a Metaverse Platform on the Self-advocacy of Adults with Severe Cerebral Palsy

Purpose The purpose of this study was to examine the effects of a situation-based augmentative and alternative communication (AAC) intervention using a metaverse platform on self-advocacy skills of adults with cerebral palsy. Method For this study, a multiple probe design across subjects was used, and four persons with severe cerebral palsy with limitations in spoken language and motor skills participated. Results First, the AAC intervention using the metaverse platform increased self-advocacy skills in four adults with severe cerebral palsy. Second, the skills learned through AAC intervention using the metaverse platform were effective even in generalization situations applied to other subjects. Third, increased skills remained above baseline even after the AAC intervention using the metaverse platform was terminated. Conclusion This study is significant in that it demonstrated the effectiveness of AAC intervention on the increase in self-advocacy skills in community scenes that require self-advocacy using the metaverse platform for people with severe cerebral palsy with limited experience in the actual community.
