Differential rates of skill acquisition and outcomes of early intensive behavioral intervention for autism

Intensive behavioral intervention for very young children with autism has received increased attention in recent years. Researchers have documented unprecedented success in educating some young children with autism, although not every child makes dramatic developmental gains. It might be useful to identify early in treatment those children who will benefit most from the current methodology and who might require slight variations in instructional format or curricular focus. The present study suggests that initial learning rates are moderately correlated with treatment outcomes after two years. Among 20 children receiving early, intensive behavioral intervention, initial acquisition of skills was correlated with later learning rates, severity of autism symptomatology and adaptive behavior profiles two years into treatment. Implications are discussed, especially in light of the universal need for intensive intervention in this population. Copyright © 1999 John Wiley & Sons, Ltd.
