ABSTRACT
Research conducted across the life span indicates that the quality of sibling relationships influences individuals’ mental and physical health, social functioning, and general well-being. This observation, combined with the fact that approximately 85% of all people have at least one sibling, underscores the importance of learning more about the nature of this lifelong relationship and the influence it has in people’s lives (Stocker, Lanthier, &
Furman, 1997). Consistent with this view, Goetting (1986) suggested that emotional support and companionship are important functions of sibling relationships across the life span. For example, children in early and middle childhood indicated that older siblings were important sources of advice and support (B. K. Bryant, 1989; Dunn, 1996). Similarly, adolescent and college-age individuals report being supported by their siblings (Cicirelli, 1980; Tucker, McHale, & Crouter, 2001). Research on siblings in old age indicates that men and women who receive support from an older sister demonstrate better mental and physical health (Bedford & Gold, 1989; Cicirelli, 1989; Connidis & Davies, 1992).
