Parents of children with autism in low-resource settings have reported exacerbated difficulties related to raising their children. In this single-case research using multiple probe design, four parent mentors and five parent peers and their children with autism in Mongolia participated in the parent peer coaching program. The intervention package, including training and coaching in evidence-based practices, was delivered via telepractice. Parent mentors completed online training and were coached by a bilingual and bicultural research assistant in a staggered fashion. Visual analysis revealed a functional relation between the intervention package and the coaching fidelity of parent mentors. Social validity data indicated that all participants were satisfied with the program and reported it was acceptable, feasible, and effective. Implications for conducting intervention research in a low-resource setting are described.
