The Functional Rating Index (FRI) is a self-report scale widely used to determine the level of disability in low back pain (LBP) populations.
This study was aimed at conducting the cross-cultural adaptation of the FRI-Arabic version (FRI-Ar) and testing the clinometric properties of FRI-Ar.
The cross-cultural adaptation process was used to develop the FRI-Ar. This study included acute and subacute LBP patients. Each patient was asked to complete the questionnaires at three time points: baseline, 24-hour follow-up, and two-week follow-up. The questionnaires used were FRI-Ar, Roland-Morris Disability Questionnaire (RMDQ), Oswestry Disability Index (ODI), Numerical Pain Rating Scale (NPRS), Global Perceived Effect Scale (GPE), and Patient-Specific Functional Scale (PSFS). Statistical analysis was carried out to measure the instrument's reliability, validity, and responsiveness.
The FRI was cross-culturally adapted to the Arabic language, and the adapted version was validated. Two hundred patients completed the questionnaires at the baseline; however, 120 patients completed the questionnaires at 24-hour and two-week follow-up. Cronbach's alpha, interclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC) for the FRI-Ar were observed as 0.85, 0.85, 1.17 (2.9%), and 3.24, respectively. The FRI-Ar showed a moderate positive correlation only with the RMDQ, ODI, and NPRS ( < 0.05). Also, it showed the responsiveness with a small effect size (ES = 0.29) and standardized response mean (SRM = 0.44).
The FRI-Ar was developed, and it showed good reliability and validity. However, it revealed the responsiveness with the small change. It can evaluate both pain and functional limitations in acute and subacute LBP patients. Before using it in the Arabic population with acute and subacute LBP, it is recommended to conduct further research to test internal and external responsiveness using an external criterion with a more extended follow-up period and suitable interventions.
功能评定指数（FRI）是一种广泛用于确定腰痛（LBP）人群残疾程度的自我报告量表。
本研究旨在对FRI阿拉伯语版（FRI-Ar）进行跨文化改编，并测试FRI-Ar的临床测量特性。
采用跨文化改编过程来开发FRI-Ar。本研究纳入了急性和亚急性LBP患者。每位患者被要求在三个时间点完成问卷：基线、24小时随访和两周随访。使用的问卷有FRI-Ar、罗兰-莫里斯残疾问卷（RMDQ）、奥斯威斯利残疾指数（ODI）、数字疼痛评分量表（NPRS）、总体感知效应量表（GPE）和患者特定功能量表（PSFS）。进行统计分析以测量该工具的信度、效度和反应度。
FRI被跨文化改编为阿拉伯语版本，且改编后的版本得到了验证。200名患者在基线时完成了问卷；然而，120名患者在24小时和两周随访时完成了问卷。FRI-Ar的克朗巴哈系数、组内相关系数（ICC）、测量标准误（SEM）和最小可检测变化（MDC）分别为0.85、0.85、1.17（2.9%）和3.24。FRI-Ar仅与RMDQ、ODI和NPRS呈中度正相关（<0.05）。此外，它显示出较小的效应量（ES = 0.29）和标准化反应均值（SRM = 0.44）的反应度。
FRI-Ar已开发出来，且显示出良好的信度和效度。然而，它显示出的变化反应度较小。它可以评估急性和亚急性LBP患者的疼痛和功能受限情况。在将其用于患有急性和亚急性LBP的阿拉伯人群之前，建议进行进一步研究，使用外部标准并延长随访期和采用合适的干预措施来测试内部和外部反应度。
