Adaptive behavior and its differences between children with autism spectrum disorder and social communication disorder.

Abstract

Lay abstract: This study compared adaptive behavior skills between children with autism spectrum disorder and social communication disorder using the Vineland Adaptive Behavior Scale-III. The researchers analyzed data from 232 children with autism spectrum disorder and 90 with social communication disorder. Key findings showed that children with social communication disorder demonstrated significantly better adaptive functioning across all areas compared to those with autism spectrum disorder. The largest differences were seen in communication and social skills. However, both groups still showed impairments compared to typical development, especially in expressive language. The study also found that younger children with lower overall adaptive behavior scores were more likely to be diagnosed with autism spectrum disorder. In addition, there was a higher proportion of males in the social communication disorder group than the autism spectrum disorder group. These results highlight important differences between autism spectrum disorder and social communication disorder, supporting their classification as distinct disorders. The findings emphasize the need for comprehensive adaptive behavior assessment during diagnosis and tailored interventions for each condition. Early identification and targeted support may be particularly crucial for children with autism spectrum disorder.
