WHAT THE TEST MEASURES

About This Assessment

Sibling Rivalry Scale Test - Symptoms and Signs

family siblings

This brief self-report measure is designed to screen for sibling-related tension and competitive feelings in children. The Sibling Rivalry Scale is intended to support a quick appraisal of how a child perceives and reacts to siblings in everyday family interactions. It is commonly referenced in Adlerian-informed discussions (Alfred Adler).

The instrument includes 10 items and typically takes about 2 minutes to complete. Responses are used to summarize the intensity of rivalry- and jealousy-related sentiments, which may help guide clinical interviewing, family consultation, and case formulation. In applied settings, the Sibling Rivalry Scale can be used to identify areas of perceived competition or strain that may warrant further assessment or intervention planning.
