Contributors to adult sibling relationships and intention to care of siblings of individuals with Down syndrome

The contribution of childhood sibling relationships to adult sibling relationships and intention to provide care was investigated in a sample in which one member of each dyad had Down syndrome. Thirty-nine adult siblings of an adult with Down syndrome who had participated in a study of sibling relationships in childhood/adolescence provided data about the quality of current relationships and of their intention to provide care for their brother/sister with Down syndrome in the future. Only behavior problems in the child with Down syndrome predicted warmth of the current adult relationship. Although adult sibling relationships were reported to be warm, the quality of neither the current nor the past relationship was associated with the reported intention to provide care.
