What does this questionnaire measure?

It assesses key features of sibling interactions, including warmth, support, conflict, and aggression. Results summarize patterns that may relate to adjustment and well-being.

It includes 35 items and typically takes about 7 minutes to complete. Most respondents can finish without breaks.

How should responses be selected?

Each item should be answered based on typical interactions over a recent period rather than a single event. If uncertain, select the option that best matches what occurs most often.

How should results be interpreted and used?

Scores describe relative strengths and difficulties in the relationship and can guide follow-up assessment or family-focused intervention planning. Results should be interpreted alongside other clinical, educational, or research information.

WHAT THE TEST MEASURES

About This Assessment

Sibling Relationship Questionnaire, SRQ Test

Sibling Questionnaire (BSQ) Test - Symptoms and Signs

family siblings

Sibling relationships can vary from supportive to highly conflictual, and the Sibling Questionnaire (BSQ) provides a brief structured way to characterize these patterns. Respondents rate common interaction behaviors and attitudes toward a brother or sister to support clinical or research description of the sibling dyad.

Developed by Judy Dunn and Robert Plomin, it includes 35 items and takes about 7 minutes to complete. The Sibling Questionnaire (BSQ) is typically used to identify relative strengths and areas of concern (e.g., frequent conflict, aggression, or low warmth) that may be relevant to family functioning and to inform follow-up assessment or intervention planning.
