Sibling relationship quality: its causes and consequences

Abstract

Current work on children's individual characteristics and family processes that contribute to variation in sibling relationship quality is reviewed. Findings from these studies are summarized in a heuristic model that specifies hypothesized links among family processes, intrapersonal characteristics, and variations in sibling relationship quality. The model is designed to provide researchers with a host of hypotheses to test and refine in future studies. The contributions that sibling relationships may make to cognitive and psychosocial development are then reviewed, with a suggestion that sibling relationships comprised of a balance of both prosocial and conflicted interactions create experiences that are most likely to nurture children's social, cognitive, and psychosocial development.
