The influence of sibling relationship quality on the social, emotional, and behavioral functioning of children and adolescents: a scoping review

Abstract

ABSTRACT Families play a pivotal role in the development of social-emotional outcomes. Recent research indicates that sibling relationship quality plays a particularly important role in child and adolescent social, emotional, and behavioral development. To date, there are few studies that have translated this information in a manner that is useful for professionals working with children, adolescents, and their families. The present scoping review aims to fill this gap in the literature. Twenty-three empirical studies published between 1990 and 2021 were reviewed and synthesized. Results highlighted the unique ways that sibling negativity and positivity influence the development of social, emotional, and behavioral outcomes. Namely, sibling negativity was found to play a primary role in influencing adverse outcomes, such as internalizing problems, externalizing problems, and social difficulties. However, in some cases, sibling positivity was found to decrease the incidence of these outcomes. Sibling positivity was also found to be a protective factor in the context of adverse life events, such as trauma. Results indicate a need for assessment strategies aimed at identifying problematic sibling relationship qualities. Additionally, results support the need for interventions that reduce sibling negativity and promote sibling positivity that can be delivered by professionals as well as families.
