Sibling conflict and aggression is often a pervasive part of family life that parents want help managing and can have negative effects on children’s well-being. The purpose of this systematic review is to evaluate current research regarding programs to reduce sibling conflict and aggression and promote positive sibling relationships. Online databases, reference lists, and Google Scholar were searched using key words and inclusion/exclusion criteria were applied. The search located five unique studies of programs focused on school-aged children. Heterogeneity of the studies precluded meta-analysis, but characteristics of the studies were systematically described. Three interventions were aimed at directly improving children’s social skills and two interventions trained parents on mediation techniques to use during sibling conflicts. Overall, of the four studies that included assessment of children’s social skills, the results were positive. Two of the three studies that evaluated sibling relationship quality demonstrated improved sibling interactions compared with the control group. With further research and evidentiary support, these programs have promise to modify sibling behaviors as part of current parenting education programs or as a stand-alone program to address sibling conflict and aggression.
