Brief Summary:
A multi-site randomized study of intensive treatment for toddlers with autism involving a three-site collaborative network plus a data coordinating center to evaluate the effects of intervention intensity and intervention style delivered for 12 months, on the progress of very young children with ASD ages 12-30 months old and their families, and the effect of children's developmental rates and autism severity on their response to intervention.
Detailed Description:
High quality, intensive early intervention is a powerful treatment for ASD, improving IQ and language markedly in randomized controlled clinical trials (RCTs), though little long term follow-up data exists. Few core characteristics that affect child change have been tested. Two potential core characteristics that invoke considerable debate among parents, professionals, and administrators are the delivery style of intervention: play-based versus discrete trial teaching, and the intensity (dosage) of intervention. This ACE treatment network conducted an RCTs to answer the following question: what are the effects of intensity and delivery style on developmental progress of toddlers with ASD?
87 young children with ASD, mean age 23.4 months who live within a specified radius near the university at each site were enrolled in one of three national sites and randomized into one of four cells varying on two dimensions: dosage - 15 or 25 hours per week of 1:1 treatment; and discrete trial teaching or naturalistic developmental-behavioral intervention. Other aspects of intervention held constant were: use of the principles of applied behavior analysis, 1:1 adult:child ratios, parent coaching in the assigned treatment, and treatment location. Developmental progress was measured frequently allowing for growth curve analysis to examine fine-grained differences in groups as well as interactions among major child and family initial variables and these two experimental variables.
