WHAT THE TEST MEASURES

About This Assessment

Sibling Rivalry Scale Test - Symptoms and Signs

family

siblings

This brief self-report measure is used to screen children’s perceptions of jealousy, competition, and comparison in sibling relationships. The Sibling Rivalry Scale can support clinical interviews and family assessment by clarifying whether a child feels overlooked, threatened, or in competition for caregiver attention.

Developed by Alfred Adler, it includes 10 items and typically takes about 2 minutes to complete. Items focus on emotional and behavioral reactions to siblings (older or younger), including rivalry-related distress and sensitivity to parental comparison. The Sibling Rivalry Scale may be used as an initial indicator of areas to explore in treatment planning and to monitor perceived sibling dynamics over time.
