The Roland-Morris Disability Questionnaire (RMDQ) was translated and then adapted and validated.
Translation of the RMDQ into simplified Chinese characters (SCRMDQ), and its cross-cultural adaptation and validation in patients with low back pain with or without radicular leg pain.
The RMDQ is used worldwide and versions in traditional Chinese characters are available in Hong Kong and Taiwan. But there is no version in simplified Chinese characters for use in Mainland China.
The original version of the RMDQ was translated and back-translated, and then cross-cultural adaptation of the simplified Chinese version was performed following published guidelines. The SCRMDQ was validated in 150 patients, 30 of whom finished the prefinal SCRMDQ and helped determine the final version. The remaining 120 patients were asked to complete the final SCRMDQ, simplified Chinese Oswestry Disability Index (SCODI), and visual analogue scale. Reliability was assessed with the final version using internal consistency by the Cronbach α coefficient and intraclass correlation coefficient; structural validity was evaluated by correspondence analysis. Then comparison of SCRMDQ and SCODI was performed.
A total of 116 patients in the final validation study finished the questionnaires completely. Their mean age was 52.17 ± 11.95 years (range, 22-78 yr) and the mean low back pain duration was 42.04 ± 60.94 months (range, 2-480 mo). The average time taken was 4.11 ± 1.48 minutes (range, 2-9 min) on SCRMDQ and 7.37 ± 3.98 minutes (range, 3-30 min) on SCODI. The mean SCRMDQ, SCODI, and visual analogue scale scores were 14.07 ± 4.79 (range, 2-24), 23.98 ± 10.38 (range, 2-47), and 57.17 ± 20.72 (range, 0-95), respectively. In the final test, the Cronbach α for internal consistency was 0.826 and intraclass correlation coefficient was 0.947; both showed adequate acceptance. Positive and statistically significant correlations were found between SCRMDQ and SCODI (r = 0.791, P < 0.01) and visual analogue scale (r = 0.493, P < 0.01), indicating sufficient structural validation. Most patients preferred SCRMDQ to SCODI, because it was simpler to understand and easier to finish.
The SCRMDQ was reliable and valid as a low back pain measurement tool in patients with or without radicular leg pain in Mainland China. The further use and research with the questionnaire were recommended.
罗伦兹-莫里斯残疾问卷（RMDQ）经过翻译、改编和验证。
将 RMDQ 翻译成简体中文（SCRMDQ），并在伴有或不伴有神经根性腿痛的腰痛患者中进行跨文化适应性和验证。
RMDQ 在全球范围内使用，香港和台湾也有繁体中文版。但在中国大陆，没有简体中文版。
原始 RMDQ 经过翻译和回译，然后根据已发表的指南进行简体中文版的跨文化适应性改编。SCRMDQ 在 150 名患者中进行了验证，其中 30 名患者完成了预最终 SCRMDQ 并帮助确定了最终版本。其余 120 名患者被要求完成最终的 SCRMDQ、简体中文 Oswestry 残疾指数（SCODI）和视觉模拟量表。使用 Cronbach α 系数和组内相关系数对最终版本进行内部一致性评估来评估可靠性；通过对应分析评估结构有效性。然后比较 SCRMDQ 和 SCODI。
在最终验证研究中，共有 116 名患者完整完成了问卷。他们的平均年龄为 52.17±11.95 岁（范围 22-78 岁），平均腰痛持续时间为 42.04±60.94 个月（范围 2-480 个月）。完成 SCRMDQ 所需的平均时间为 4.11±1.48 分钟（范围 2-9 分钟），完成 SCODI 所需的平均时间为 7.37±3.98 分钟（范围 3-30 分钟）。SCRMDQ、SCODI 和视觉模拟量表的平均得分分别为 14.07±4.79（范围 2-24）、23.98±10.38（范围 2-47）和 57.17±20.72（范围 0-95）。在最终测试中，内部一致性的 Cronbach α 为 0.826，组内相关系数为 0.947；两者都表现出足够的可接受性。SCRMDQ 与 SCODI（r=0.791，P<0.01）和视觉模拟量表（r=0.493，P<0.01）呈正相关且有统计学意义，表明结构验证充分。大多数患者更喜欢 SCRMDQ 而不是 SCODI，因为它更易于理解和完成。
SCRMDQ 作为中国大陆伴有或不伴有神经根性腿痛的腰痛患者的测量工具具有可靠性和有效性。建议进一步使用和研究该问卷。
