WWC Review of the Report "Randomized, Controlled Trial of the LEAP Model of Early Intervention for Young Children With Autism"

Apr 10, 2013 -- 3:38 pm
What is this study about?
The study examined whether a full two-year
Learning Experiences and Alternative Program for Preschoolers and Their Parents (LEAP) training and support model for teachers was superior in improv- ing outcomes of preschool children with Autism Spectrum Disorder (ASD), as compared to a limited LEAP model in which no professional development support was provided.
Fifty preschool classrooms from 16 districts and seven states across the United States were ran- domly assigned to either intervention or comparison conditions. Teachers in classrooms assigned to the intervention group received written LEAP materi- als, skill area presentations and demonstrations
by LEAP trainers, onsite training and support, and maintenance checks. Comparison classroom teach- ers received written LEAP materials and videos, but no in-person training or ongoing support. In total, there were 177 children with ASD in the full LEAP training classrooms and 117 children with ASD in the comparison classrooms.
