Researchers at the University of North Carolina at Chapel Hill have found that preschoolers with Autism Spectrum Disorder (ASD) who receive high-quality early intervention benefit developmentally regardless of the treatment model used—a surprising result that may have important implications for special-education programs and school classrooms across the country.
Previous research has shown that when children with ASD have access to early intervention via treatment programs, they improve developmentally. Until now, however, debate has persisted over which approach to use, said Boyd. The study appeared in the June issue of Journal of Autism and Developmental Disorders.
Two frequently used comprehensive treatment models have a long history: LEAP (Learning Experiences and Alternative Program for Preschoolers and their Parents) and TEACCH (now known only by its acronym).
FPG's study examined the relative effects of the LEAP and TEACCH school-based comprehensive treatment models when compared to each other and to special-education programs that do not use a specific model. The multisite study took place only in high-quality classrooms and enrolled 74 teachers and 198 3- to 5-year-olds in public school districts.
The study found that children made gains over the school year regardless of the classroom's use of LEAP, TEACCH or no specific comprehensive treatment model. "Each group of children showed significant positive change in autism severity, communication and fine- motor skills," said Kara Hume, FPG scientist and co-author. "No statistically significant differences were found among models, which challenged our initial expectations—and likely the field's."
