Predictors of Adaptive Behaviors in Individuals on the Autism Spectrum as Assessed by Teachers and Parents: An Analysis Based on ABAS-3

<b>Objectives:</b> This present study focuses on analyzing the adaptive behaviors of individuals on the autism spectrum as perceived by parents and teachers of these individuals. <b>Methods:</b> This study was conducted in Poland with the use of the ABAS-3 (Adaptive Behavior Assessment System). The ABAS-3 tool involves both parents (or primary caregivers) and teachers in the diagnostic process and monitoring of adaptive development. The study included 99 individuals (29 girls, 70 boys) aged between 5 and 21 years. <b>Results:</b> The analysis of the results showed statistically significant discrepancies in the perception of adaptive skills diagnosed as assessed by parents and teachers. Furthermore, differences were found in the predictors of the General Adaptive Composite and adaptive domains. <b>Conclusions:</b> The results indicate the complexity of the assessment of adaptive skills by a parent of a child with autism spectrum disorder, as well as a teacher, and the need to include different perspectives in the process of diagnosing and supporting individuals with ASD.
