Abstract

Purpose: The Rivermead mobility index (RMI) is a patient self-reported outcome (PRO) that measures patients' mobility. This study aimed to translate and cross-culturally adapt the (RMI) into Arabic and to assess its validity and psychometric properties.

Method: RMI was translated into Arabic in accordance with international consensus guidelines. Using a cross-sectional design, one hundred patients with Multiple Sclerosis completed the Arabic version of the Rivermead Mobility Index (RMI-Ar), the Barthel Index (BI), and the Multiple Sclerosis Impact Scale-29 (MSIS-29), which includes two subscales for the physical (PHYS) and psychological (PSYCH). To assess test-retest reliability, fifty participants were asked to retake the RMI-Ar after a two-week interval.

Results: The RMI-Ar was simple and understandable to patients with MS in Saudi Arabia. The internal consistency of the RMI-Ar was excellent (Cronbach's alpha = 0.908), and test-retest reliability was strong (ICC = 0.908). The minimal detectable change between the test and retest was 26.8% for RMI. Additionally, the RMI-Ar demonstrated good face and content validity, confirming that all items were relevant, clear, and concise, as well as construct validity, shown by strong positive correlations with the Barthel Index (rho = 0.73) and weak negative correlations with the MSIS-29 psychological domain (rho = -0.23). No floor or ceiling effect was observed, affirming the scale's capacity to differentiate between participation levels.

Conclusion: The RMI-Ar questionnaire is a valid and reliable outcome measure to use in clinical and research settings.

多发性硬化症患者Rivermead流动性指数（RMI）量表阿拉伯语版的翻译、跨文化适应和心理测量特性

目的：Rivermead活动能力指数（RMI）是一种衡量患者活动能力的患者自我报告结果（PRO）。本研究的目的是翻译和跨文化适应（RMI）到阿拉伯语，并评估其有效性和心理测量特性。方法：按照国际共识指南将RMI翻译成阿拉伯文。采用横断设计，100名多发性硬化症患者完成了阿拉伯语版的Rivermead活动指数（RMI-Ar）、Barthel指数（BI）和多发性硬化症影响量表-29 (MSIS-29)，其中包括生理（PHYS）和心理（PSYCH）两个子量表。为了评估重测信度，50名参与者被要求在间隔两周后重测RMI-Ar。结果：RMI-Ar对沙特阿拉伯MS患者简单易懂。RMI-Ar的内部一致性极好（Cronbach’s alpha = 0.908），重测信度强（ICC = 0.908）。RMI测试和重新测试之间的最小可检测变化为26.8%。此外，RMI-Ar显示出良好的面孔效度和内容效度，证实了所有项目都是相关的，清晰的，简洁的，以及结构效度，与Barthel指数呈强正相关（rho = 0.73），与MSIS-29心理域呈弱负相关（rho = -0.23）。没有观察到最低或最高效应，肯定了量表区分参与水平的能力。结论：RMI-Ar问卷在临床和研究中是一种有效可靠的结果测量方法。
