Evaluation of the effectiveness of behavioral interventions for autism spectrum disorders: A systematic review of randomized controlled trials and quasi-experimental studies.

This article systematically reviews the efficacy of behavioral therapy interventions for autism spectrum disorder (ASD) in children and adolescents, focusing on randomized controlled trials (RCTs), quasi-experimental, and clinical trial comparisons. Behavioral interventions examined include applied behavior analysis (ABA), discrete trial teaching (DTT), pivotal response treatment (PRT), treatment and education of autistic and communication handicapped children (TEACCH), early start Denver model (ESDM), early intensive behavioral intervention (EIBI), and picture exchange communication system (PECS). The review found that all these approaches positively impact ASD symptoms, with naturalistic methods like PRT and PECS improving social communication, ESDM enhancing receptive language in preschoolers, and structured interventions such as EIBI and TEACCH improving adaptive functioning. Despite these findings, the authors note a scarcity of high-quality research and emphasize the need for further rigorous comparative studies to identify cost-effective, evidence-based behavioral treatments accessible to ASD patients and their families.
