Progress and outcomes for children with autism receiving parent-managed intensive interventions

Parent-managed behavioral interventions for young children with autism are under-researched. We analyzed data from 66 children served by 25 different early intervention consultants. After a mean of 31.6 months of intervention IQ scores had not changed (N = 22). Vineland adaptive behavior scores had increased significantly by 8.9 points (N = 21). No children aged > 72 months attained normal functioning, i.e., IQ > 85 and unassisted mainstream school placement (N = 42). Progress for 60 children across 12 months was found for mental age (5.4 months), adaptive behavior (9.7 months), and language (5.1 months). The interventions did not reproduce results from clinic-based professionally directed programs. The effectiveness of the parent-managed intervention model as it has developed and the adequacy of professional services in that model are discussed. (C) 2001 Elsevier Science Ltd.
