Children with Asperger Syndrome (AS) who attend mainstream settings face social skills deficits that have not been adequately explored. This study aims to examine social skills through self-reports of children with AS (N = 21) and a matched group of typically developing peers, as well as reports from their mothers, fathers, and teachers. Results showed that children with AS had more social skills deficits according to all raters and that they reported more aggressiveness/antisocial behavior, more conceit/haughtiness, more loneliness/social anxiety, and less assertiveness than controls. The level of agreement between raters varied significantly, suggesting that social skills are best studied with multiple informants.
