Almost half of all children with autism spectrum disorder have average cognitive abilities, yet outcome remains poor. Because outcome in HFASD is more related to adaptive behavior skills than cognitive level it is important to identify predictors of adaptive behavior. This study examines cognitive and demographic factors related to adaptive behavior, with specific attention to the role of executive function (EF) in youth with HFASD aged 4–23. There was a negative relationship between age and adaptive behavior and the discrepancy between IQ and adaptive behavior increased with age. EF problems contributed to lower adaptive behavior scores across domains. As such, it is important to target adaptive skills, and the EF problems that may contribute to them, in youth with HFASD.
