Sibling relationships: Considerations for family therapy

Siblings are frequently overlooked as an essential focus in family‐based interventions with children. And yet, 80–85% of children worldwide have at least one sibling (Campion Barr & Killeron, 2015). Some have suggested that sibling relationships are a prototype for peer relationships in childhood and adulthood. This makes intuitive sense when one considers the arena within which siblings grow and mature together, with the dynamics involving strong attachments, cooperation, and rivalry and conflict. For instance, a positive sibling relationship can provide emotional support and a sense of security, while a negative relationship can lead to increased stress and anxiety.
