Hypothesis
The study aims to assess the validity and reliability of the Brace Questionnaire (BrQ) for measuring quality of life in brace-treated adolescents with scoliosis.
Conclusion
The Brace Questionnaire (BrQ) is a reliable, valid, and responsive tool for assessing quality of life in adolescents with idiopathic scoliosis treated with a brace.
Supporting Evidence
- BrQ was assessed for psychometric properties including item convergent validity and internal consistency reliability.
- An item convergent validity ≥ 0.40 was satisfied by all items in the study.
- Cronbach's alpha coefficient for the BrQ was 0.82, indicating satisfactory internal consistency.
