How do children and youth with autism spectrum disorder self-report on behavior? A study of the validity indexes on the Behavior Assessment System for Children, Second Edition, self-report of personality.

Using self-report questionnaires is an important method in the assessment and treatment of children with autism. Self-reports can provide unique information about children's feelings and thoughts that is not available through other methods such as parent-reports. However, many clinicians are not sure whether children with autism can provide accurate self-reports. To study this, we examined 139 children and youth with and without autism aged 8-17 years. We looked at the effect of having autism, as well as other factors such as age, intelligence quotient, and attention problems on the validity of self-reports in these children. We examined if the children gave overly negative or positive answers and if they responded to the questions randomly or without paying attention. We found that children with autism can provide acceptable self-reports. However, they have more validity problems compared to their peers without autism. Our findings showed that this difference might be related to having attention problems in addition to autism, rather than having autism by itself. Children, with and without autism spectrum disorder, with fewer attention problems and higher intelligence quotient scores and those in the older age group, showed better validity. This article suggests that clinicians can use self-report measures for children with autism, but they should pay attention to important factors such as children's intelligence quotient and attention problems.
