Abstract

The Behavior Assessment System for Children, Second Edition (BASC-2; Reynolds & Kamphaus 2004) is a behavior rating scale commonly used in preschool settings. In addition to measuring behavioral constructs such as hyperactivity, social skills, and adaptive functioning, the BASC-2 includes a Developmental Social Disorders (DSD) content scale that evaluates the presence of behaviors commonly associated with pervasive developmental disorders, including items related to self-stimulation, withdrawal and poor socialization. This study compared the T-scores of toddler and preschool-aged children diagnosed with an autism spectrum disorder (ASD) to children diagnosed with other developmental delays, and typically developing children using the BASC-2 Parent Rating Scales, Preschool form. Participants from the ASD group obtained significantly higher T-scores than the typically developing group on the Hyperactivity, Atypicality, Withdrawal, and Attention Problems scales, and obtained significantly lower T-scores on the Adaptability, Social Skills, Activities of Daily Living, and and Functional Communication scales. Significant differences were not observed between participants in the ASD group and those diagnosed with other developmental delays. However, the DSD scale was effective in distinguishing between groups, with participants in the ASD group obtaining significantly higher T-scores on the DSD scale than those diagnosed with other developmental delays and typically developing children.
