Adaptive behavior of school-aged children with Autism Spectrum Disorder

Children with Autism Spectrum Disorder (ASD) face challenges related to their functioning, also known as adaptive behavior. Studies in recent literature explore the association between adaptive behavior and cognitive ability in children with ASD.
Aim: The present study investigates adaptive behavior and adaptive skills in children with ASD in relation to their cognitive ability.
Methods: In the present study, the sample consisted of 54 children with ASD, with a minimum Intelligence Quotient-IQ of “70”, who were admitted to a Child Psychiatric Hospital Clinic. Screening of functional and cognitive difficulties was performed by administering the Vineland Adaptive Behavior Scales (VABS) and Wechsler's Intelligence Scale for children-III (WISC-III), respectively.
Results: Children with ASD exhibited deviations in adaptive behavior, with a pattern of deficits in adaptive skills (p<0.001). The group with high general cognitive score showed higher performance in the areas of Communication and Socialization, compared to the group with low general cognitive score. Both groups showed significant deficits in Daily Living Skills. The relationship between adaptive behavior/adaptive skills was investigated in relation to general, verbal and performance IQ (VIQ-PIQ). The general cognitive score was found to predict the performance of adaptive behavior. In the high cognitive ability group, the verbal and performance cognitive score predicted performance in Communication and Activities of Daily Living, respectively.
Conclusions: The functioning of children with ASD is reflected in adaptive behavior, where a pattern of deficits is presented in relation to the cognitive ability.
