Theory of mind, severity of autistic symptoms and parental correlates in children and adolescents with Asperger syndrome.

This study addresses the theory of mind (ToM) ability of Asperger's syndrome/high-functioning autism (AS/HFA) children and their parents and the severity of the autistic symptoms. Fifty-three families, each consisting of a mother, father and a child, participated in this study (N=159). The 53 children in the sample included 25 children diagnosed with AS/HFA and 28 typically developing (TD) children. The Social Attribution Task (SAT) and tests assessing autistic symptoms were used. AS/HFA children had lower scores than TD children on three of the SAT indices (Person, ToM Affective, and Salience). Fathers of AS/HFA children did not have lower scores than fathers of TD children on the SAT task, whereas mothers of AS/HFA children had lower scores on the Person index, a pattern similar to seen in their children, suggesting a possible genetic contribution of mothers to ToM deficit in AS/HFA children.
