Discrepancies When Assessing Interpersonal Problem-Solving Skills in Autism Spectrum Disorder: A Diagnostic Indicator

In children with autism spectrum disorder (ASD), there are often discrepancies between direct assessment and third-party reports. We compared these children with groups with/without difficulties in interpersonal problem-solving skills in order to determine whether these discrepancies appear and if they could be a diagnostic indicator for ASD. There were 91 participants (ages 7–13): 28 children with ASD, 36 in a high family risk situation, and 27 typically developing children, all tested with direct measures and third-party reports. Results showed discrepancies only in the ASD group. Consequently, direct performance measures and third-party reports seem to be evaluating different constructs in children with ASD. In addition, both types of measures discriminate between groups, such that both are needed, especially in diagnostic assessments.
