This study investigated differences in parent and teacher/professional ratings of behaviors in children with autism. Caregivers rated adaptive skills like daily living higher than teachers. Ratings of problem behaviors did not differ. This may be because behaviors are environment-specific and children with autism do not generalize skills across contexts like home vs school. The study provides insight into effectively assessing behaviors in different environments using multiple informants. Limitations include a clinical sample and lack of observational data. Results can help clinicians understand how to collect the most accurate behavioral data.
