Brief Report: Developmental Trajectories of Adaptive Behavior in Children and Adolescents with ASD
Research suggests that individuals with autism spectrum disorder (ASD) have significant difficulties with adaptive behavior skills including daily living and functional communication skills. Few studies have examined the developmental trajectory of adaptive behavior across childhood and adolescence. The present study examined longitudinal trajectories of adaptive behavior in a community-based clinic sample of 186 individuals with ASD. The overall pattern indicated an initial increase in adaptive behavior during early childhood followed by a plateau in skills during adolescence for individuals of all IQ groups. Given the importance of adaptive behavior for employment and quality of life, this study emphasizes the importance of targeting adaptive behavior during adolescence to insure continued gains.
