Social and language skills in adolescent boys with Asperger syndrome.

Twenty-one adolescent boys with Asperger syndrome and 21 boys matched on age and an estimate of IQ were assessed using standardized measures of social perception (Child and Adolescent Social Perception Measure, CASP), social skills (parent, teacher, and student forms of the Social Skills Rating System, SSRS), number of close friends and frequency of contact (Child Behavior Checklist) and expressive and receptive language (Clinical Evaluation of Language Fundamentals-Revised). There were significant differences between groups on CASP scores, SSRS scores, number of friends, frequency of contact and social competence. There was also a significant difference on receptive language. The clinically and statistically significant differences between the groups on the measures of social skills help us understand the nature of the social deficits in Asperger syndrome and suggest the need to focus on specific deficits. These findings are discussed in relation to diagnostic criteria and intervention.
