Siblings of children with autism: Predictors of adjustment

As the prevalence of autism increases, so does the need to examine the effects of autism on family members of children with autism. The current study evaluated possible predictors of adjustment in siblings of children with autism. Aspects of the parents’ functioning as caregivers for a child with autism were examined to determine whether they predicted the adjustment of the child's sibling. Two hundred caregivers of 4–10-year-old children with autism who had at least one sibling without autism participated by filling out questionnaires online. Parental satisfaction with the role of caregiver for the child with autism was negatively correlated with difficulties in sibling adjustment, and it was the only significant predictor of sibling adjustment in a hierarchical regression analysis. Parental stress and parental self-efficacy were not unique contributors to sibling adjustment when other parental variables were considered. No significant relationship was found between parental therapy involvement and sibling adjustment, or between parental educational involvement and sibling adjustment. The lack of parental involvement as a predictor of sibling adjustment adds new findings to the current literature, which had found such a relationship in a previous study with a smaller sample.
