Building Family Capacity: supporting multiple family members to implement aided Language modeling

Abstract

Family-centered capacity-building practices have been shown to benefit children and families. However, limited research explores these practices for children who use augmentative and alternative communication. This study explored an intervention to teach family members to implement an Aided Language Modeling (ALM) strategy across natural activities at home. A single case multiple probe design was used to evaluate the intervention with five family members and a girl with autism. Results showed the intervention increased family members' percentage of high-fidelity ALM strategy use and rate of ALM. Descriptively, a modest increase was also observed in the proportion of the child's communication using the speech-generating device. Social validity interviews suggested the goals, procedures, and outcomes were socially valid and supported family capacity building.
