Sibling Rivalry Scale Test - Symptoms and Signs

family

siblings

This brief measure assesses perceived competition and jealousy in sibling relationships from the child’s perspective. The Sibling Rivalry Scale is designed to support a rapid screening of rivalry-related feelings and behaviors that may be relevant to family dynamics.

It consists of 10 items and typically takes about 2 minutes to complete. Developed by J. Dunn, the Sibling Rivalry Scale may be used in clinical or educational settings to inform case formulation, guide discussion with caregivers, and support decisions about further assessment or intervention when concerns about sibling conflict are present.
