Sibling support as a mediator of sibling relationship quality and well-being

Colleen L Kelly, Purdue University


This paper proposed to study the effect of sibling support (SS) on sibling relationship quality (SRQ) and well-being. The goal of this study was to understand some factors that may influence SS, as well as understand if SS mediates the relationship between SRQ and well-being. This study was grounded in the family life cycle theory (Carter & McGoldrick, 2005), and it aimed to discover whether SS varied throughout different life cycle stages. It was hypothesized that SS mediates the relationship between SRQ and well-being. It was also hypothesized that SS would be lowest during the young adult stage of the life cycle. Results did not support either hypothesis; SS was not found to be a mediating variable between SRQ and well-being. SS was not found to have a significant relationship with the family life cycle stages. SS was found to have a positive, significant relationship with SRQ.
