Abstract

Purpose: To perform a cross-cultural adaptation and validation of the Brazilian-Portuguese versions of the Brace Questionnaire in adolescent idiopathic scoliosis.

Methods: A forward-backward translation process was employed to produce a Brazilian Portuguese version of the Brace Questionnaire, followed by comprehensive cross-cultural adaptation stages. The measurements of internal consistency and test-retest reliability were assessed by Cronbach's a and intraclass correlation coefficient (ICC), respectively. The Pearson's correlation coefficient was used to analyze the concurrent validity by comparison with the Scoliosis Research Society-22r questionnaire.

Results: A total of 84 scoliosis patients (age 13.4 ± 2.0 years, thoracic Cobb angle 33.3° ± 13.8°, and lumbar Cobb angle 29.8° ± 14.3°) were included. The Brace Questionnaire showed excellent internal consistency (Cronbach α = 0.93) and moderate reliability (ICC = 0.86). The correlations between the Brace Questionnaire and Scoliosis Research Society-22 were r = 0.66; p = 0.011. In addition, it was found that the Brazilian version of the Brace Questionnaire does not have ceiling and floor effects.

Conclusions: The Brazilian-Portuguese adaptation of the brace questionnaire shows excellent reliability and can be a valid tool for psychometric assessment in adolescent idiopathic scoliosis.

巴西葡萄牙语版 Brace 问卷的翻译、跨文化改编和临床特性。

目的：对巴西-葡萄牙语版本的青少年特发性脊柱侧凸支撑力问卷进行跨文化改编和验证：方法：采用前向-后向翻译程序制作巴西葡萄牙语版的支架问卷，然后进行全面的跨文化改编。通过克朗巴赫 a 和类内相关系数（ICC）分别评估了内部一致性和重复测试可靠性。通过与脊柱侧凸研究学会-22r问卷的比较，使用皮尔逊相关系数分析了并发效度：共纳入 84 名脊柱侧弯患者（年龄为 13.4 ± 2.0 岁，胸椎 Cobb 角度为 33.3° ± 13.8°，腰椎 Cobb 角度为 29.8° ± 14.3°）。支具问卷显示出极佳的内部一致性（Cronbach α = 0.93）和适度的可靠性（ICC = 0.86）。支具问卷与脊柱侧凸研究协会-22 的相关性为 r = 0.66；p = 0.011。此外，研究还发现巴西版支撑力问卷不存在上限和下限效应：结论：巴西-葡萄牙语改编的支具问卷显示出极佳的可靠性，可作为青少年特发性脊柱侧凸心理测量评估的有效工具。
