WHAT THE TEST MEASURES

About This Assessment

Sibling Rivalry Scale Test - Symptoms and Signs

family

siblings

This brief caregiver- or child-report measure is designed to screen for jealousy, competition, and tension in sibling relationships. The Sibling Rivalry Scale supports quick identification of areas of conflict that may warrant further clinical interview or family-focused intervention.

Developed by J. Dunn, it consists of 10 items and typically takes about 2 minutes to complete. Responses can help characterize the child’s attitudes toward a brother or sister (older or younger) and highlight patterns relevant to family or school-based consultation. The Sibling Rivalry Scale is not intended as a stand-alone diagnostic tool; results are best interpreted in context of developmental level, family dynamics, and collateral information.
