Abstract
In South Korea, there is currently a massive gap between the demand and the supply of quality applied behavior analysis (ABA) services for children with autism spectrum disorder (ASD) and their families. However, the literature on the implementation and effectiveness of ABA intervention mainly comes from Western countries, and the voices of Asian countries are scarcely heard. The present article reports data collected from the KAVBA Center in Seoul, South Korea, as a direct replication of the CABAS educational model. Eleven 3- to 4-year-old children with ASD were the participants in the study and attended the center for 1 year. Our pre- and postintervention data show that the CABAS model provided an effective and cost-efficient service for children with ASD in South Korea.
