WHAT THE TEST MEASURES

About This Assessment

Sibling Questionnaire (BSQ) Test

family siblings

This questionnaire is used to characterize sibling relationship functioning in the family context. The Sibling Questionnaire (BSQ) provides a brief, structured approach to describing patterns of day-to-day interaction and perceived relationship quality.

The measure consists of 35 items and typically takes about 7 minutes to complete. Item content is oriented toward behaviors and experiences that can help differentiate more supportive, reciprocal relationships from those marked by frequent conflict or aggression. Results from the Sibling Questionnaire (BSQ) are commonly interpreted as part of a broader clinical or research assessment of family dynamics and may help guide case formulation and treatment planning when sibling interactions are a clinical concern.
