Sibling bullying is associated with various psychosocial difficulties. We investigated this in 231 individuals with Autism Spectrum Disorder (ASD) and 8180 without ASD between middle childhood (age 11 years) and early adolescence (age 14 years). On the whole, self-reported sibling bullying decreased from middle childhood to early adolescence.…

We tested a novel methodological approach to examine associations between characteristics of autistic children and outcomes for siblings. Cluster analysis was used to define five groups of children with autism (n = 168) based on autism symptoms, adaptive behavior, pro-social behavior, and behavior problems. Primary and secondary parent carers, and…

Social support can buffer against stressors often associated with having family members with autism spectrum disorder. This study included 112 parents and typically developing siblings of children with autism spectrum disorder. Relations between self-reported typically developing sibling emotional and behavioral problems and discrepancy between…

Despite the prevalence of studies showing increased stress among mothers of individuals with autism spectrum disorders, few studies have examined general stress among typically developing siblings. This study used an online survey to compare the levels of self-reported stress between adolescent siblings of individuals with autism spectrum disorder…

Siblings play an important role in shaping the developmental trajectories of individuals with autism spectrum disorder. Having siblings has been associated with better social communication, non-verbal communication, and theory of mind abilities in autism spectrum disorder. However, little is known about the impact of siblings on adaptive skill…

This study compared sibling interactions between 24-month-old children and their older sibling with ASD (high-risk; n = 24) with 24-month-old children and their typically developing older sibling (low-risk; n = 32). First, high-risk sibling pairs showed lower levels of positive behaviour and younger siblings of children with ASD imitated their…

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…

Significant attention has been paid in the literature to sibling relationships and the effects of birth order, family size, and gender on such relationships. Although these are important areas to study, there is relatively little research on the effects of autism spectrum disorders (ASD) on sibling relationships. The existent research identifies…

We investigated sibling relationships and wellbeing in adolescents and adults with a sibling with an autism spectrum disorder (ASD). Adolescents engaged in more shared activities than did adults. Adolescents reported greater social support, greater use of emotion-focused coping strategies, and less use of problem-focused coping than adults. In…

In this article, we review the literature on siblings of individuals with autism spectrum disorders (ASD) from a lifespan developmental perspective, from infancy through adulthood, focusing on the sibling relationship and sibling well-being. We situate this review within the larger body of research on siblings of individuals with developmental…
