Abstract

Caregiver report on the Adaptive Behavior Assessment System-II (ABAS) for 40 high-functioning individuals with Autism Spectrum Disorders (ASD) and 30 typically developing (TD) individuals matched for age, IQ, and sex ratio revealed global adaptive behavior deficits in ASD, with social skills impairments particularly prominent. Within the ASD group, adaptive communication skills were positively related to IQ while global adaptive functioning was negatively associated with autism symptomatology. Autistic behavior ratings related negatively to ABAS scores in the TD but not the ASD group. This investigation demonstrates: the utility of an adaptive functioning checklist for capturing impairments, even in high-functioning individuals with ASD; and that a relationship between social abilities and autism exists independently of intelligence.

Figure 1. ABAS relative skill area weaknesses by group
Each participant’s mean skill area score was subtracted from each of his/her skill area scores. The resulting individual difference scores were compared with the cut off values supplied in the ABAS manual denoting scores that deviate significantly from the participant’s mean score, suggesting relative strength or weakness in a skill area. The percentage of participants in each diagnostic group with a relative weakness in a given skill area is shown here.
