Sibling Relationships in Middle and Older Adulthood

Abstract Research on various aspects of the sibling relationship in adulthood, with a focus on middle and older adulthood, will be reviewed. Attachment theory, which has often been utilized to explain relationships among siblings, will be discussed. Equity theory, as it relates to siblings' roles as caregivers, will also be examined. Closeness among siblings, social support, elderly siblings, and death of a sibling are among the specific topics that will be addressed. A number of factors contributing to the quality of the sibling relationship will also be considered. These include the gender and marital status of the siblings. Finally, future research ideas concerning adult siblings will be suggested.
