Although it is well known that families of children with an autism spectrum disorder (ASD) are at risk for increased stress and other problems, little is known about what child characteristics may mediate that risk. To address the impact of child behavior problems on family health, we examined data collected from 136 families raising children with…

Research with siblings of children with Autism Spectrum Disorders (ASD) suggests that they may be at increased risk for behavioural and emotional problems and relatively poor sibling relationships. This study investigated a diathesis-stress model, whereby the presence of Broad Autism Phenotype features in the typically developing siblings might…

Existing literature regarding the adjustment of siblings of children with an autism spectrum disorder (ASD) remains inconclusive, with some studies showing positive adjustment, others showing negative adjustment, and others showing no difference when compared to siblings of typically-developing children.

Of the children with ASDs, 47.0% (78/166) had at least one…

This study examined the nature of cognitive and behavioral sex differences in children with autism spectrum disorders (ASDs) and two comparison groups: a group of typically developing (TD) children and a group of unaffected siblings of ASD children. Sex differences in core autistic symptoms, co-occurring behavioral symptoms, and cognitive styles…

There is very little known about how sibling characteristics may influence the social functioning of a child with an autism spectrum disorder (ASD). The current study utilized data from the Simons Simplex Collection (SSC; n=1355 children with ASD and 1351 siblings) to investigate this relationship. Phenotypic measures included (a) the "Autism…

Stimulus properties of toys may impact the type and amount of play observed between children with autism and their playmates.
