A programmatic description of an early, intensive behavioral intervention program in Australia

Abstract There is currently limited research on early, intensive behavioral intervention (EIBI) within Australia. The purpose of this paper was to provide a programmatic description and preliminary findings of an intervention approach which provides a high level of intensity of intervention to preschool aged children diagnosed with autism spectrum disorder (ASD). A total of 154 children with autism participated in the program from 2011 to 2022. At the group level, children who received 27 hr per week of intervention showed significant gains on standardized cognitive and adaptive behavior measures during an average one year of intervention. Further examination of the response to intervention at an individual level demonstrated that 84% of children showed an acceleration in their rate of learning during intervention, with 52% more than doubling their rate of learning in this time. Age was determined to predict improvement in developmental trajectory, but intake cognitive abilities did not. In general, children who commenced intervention at a younger age made substantial improvements in their rate of learning, but children who commenced intervention at an older age made even greater improvements relative to their skills at commencement. The results as well as limitations given the exploratory nature of this paper are discussed, along with implications for addressing the needs of young autistic children in Australia.
