Background

The Back Pain Attitudes Questionnaire (Back-PAQ) was developed to evaluate attitudes and beliefs of the general public, people with back pain, and healthcare professionals about the spine.

Objectives

To translate and cross-culturally adapt the Back-PAQ (34-item and 10-item versions) into Brazilian-Portuguese (Back-PAQ-Br) and test its measurement properties in a Brazilian sample.

Methods

The cross-cultural adaptation and testing of the measurement properties followed the recommendations of international guidelines. Members of the general public, people with back pain, and healthcare professionals, for a total of 139 individuals, took part in the assessment of internal consistency, construct validity, and ceiling and floor effects. The Hospital Anxiety and Depression Scale (HADS) and the Brazilian-Portuguese version of the Tampa Scale of Kinesiophobia (TSK) were used to evaluate construct validity. Test-retest reproducibility was determined on 77 participants. Retest was performed a minimum of 1 week and a maximum of 2 weeks from the original test.

Results

There was very high agreement between translators (88.2%). The Back-PAQ-Br showed excellent internal consistency (Cronbach’s alpha 0.92) and excellent reproducibility (ICC 0.94; SEM 5.14 points on a 136 point scale), with a smallest detectable change (90% confidence level) of 11.93 points. There was strong correlation between Back-PAQ-Br and TSK (r = -0.72) and very weak correlation between Back-PAQ-Br and HADS (r = -0.23 for both depression and anxiety domains). No ceiling/floor effects were observed.

Conclusion

The translation process and cross-cultural adaptation had very high agreement between translators. The Back-PAQ-Br has excellent measurement properties that are similar to the properties of the original version.

背痛态度问卷：对巴西-葡萄牙语和测量特性的跨文化适应

背景

背痛态度问卷 (Back-PAQ) 旨在评估公众、背痛患者和医疗保健专业人员对脊柱的态度和信念。

目标

将 Back-PAQ（34 项和 10 项版本）翻译和跨文化改编为巴西-葡萄牙语 (Back-PAQ-Br)，并在巴西样本中测试其测量特性。

方法

测量特性的跨文化适应和测试遵循国际指南的建议。共有 139 名公众、背痛患者和医疗保健专业人员参与了内部一致性、结构效度以及天花板和地板效应的评估。使用医院焦虑和抑郁量表 (HADS) 和巴西-葡萄牙版的坦帕运动恐惧症量表 (TSK) 来评估结构效度。对 77 名参与者确定了重测重现性。从最初的测试开始，重新测试最少 1 周，最多 2 周。

结果

译者之间的一致性非常高（88.2%）。Back-PAQ-Br 显示出出色的内部一致性（Cronbach α 0.92）和出色的再现性（ICC 0.94；SEM 5.14 分，136 分），最小可检测变化（90% 置信水平）为 11.93 分。Back-PAQ-Br 和 TSK 之间有很强的相关性（r = -0.72），而 Back-PAQ-Br 和 HADS 之间的相关性非常弱（对于抑郁和焦虑领域，r = -0.23）。没有观察到天花板/地板效应。

结论

译者之间的翻译过程和跨文化适应具有很高的一致性。Back-PAQ-Br 具有出色的测量特性，与原始版本的特性相似。
