摘要
研究设计横断面研究：评估阿拉伯语版 Oswestry 失能指数（ODI）在腰背痛患者中的结构有效性：阿拉伯语 ODI 目前用于临床和研究环境中的残疾评估，但其结构有效性仍存在问题：方法：从沙特阿拉伯两家医院的理疗科招募患有腰背痛的成年患者。参与者填写了阿拉伯语 ODI 和数字疼痛评分量表。研究人员进行了探索性因子分析（EFA）和确证性因子分析（CFA），以检验 ODI 的因子结构。EFA采用最大似然提取法和平行分析法，CFA评估拟合优度指数（Chi-square统计量（χ2）、Tucker-Lewis指数（TLI）、比较拟合指数（CFI）、均方根近似误差（RMSEA）和标准化均方根残差（SRMR）），以确认因子结构：共有 113 名患者（47.8% 为男性，52.2% 为女性）参与了研究。EFA确定了阿拉伯语ODI的单维结构，其中一个因子解释了总方差的45.8%。所有项目都有明显的因子载荷，载荷从 0.48（睡眠）到 0.84（性生活和社交生活）不等。CFA 证实了这一单维结构，得出了良好的拟合指数（χ²=49.53，PC 结论：阿拉伯语 Oswestry 残疾指数作为一种单维度残疾测量方法，在阿拉伯语腰背痛患者中显示出足够的结构有效性。这些发现支持在临床和研究环境中继续使用 Oswestry 残疾指数进行残疾评估，并支持使用一个总分代表单一潜在结构的有效性：3.
The Arabic Oswestry Disability Index is a Unidimensional Measure: Exploratory and Confirmatory Factor Analysis.
Study design: Cross-sectional study.
Objective: To evaluate the structural validity of the Arabic version of the Oswestry Disability Index (ODI) in patients with low back pain (LBP).
Summary of background data: The Arabic ODI is currently used in clinical and research settings to assess disability, but questions remain regarding its structural validity.
Methods: Adult patients with LBP were recruited from physical therapy departments of two hospitals in Saudi Arabia. Participants completed the Arabic ODI and the Numeric Pain Rating Scale. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted to examine the factor structure of the ODI. Maximum likelihood extraction and parallel analysis were used in the EFA, and the goodness-of-fit indices (Chi-square statistics (χ2), Tucker-Lewis index (TLI), comparative-fit index (CFI), root mean square error of approximation (RMSEA) and standardized root mean residual (SRMR)) were assessed in the CFA to confirm the factor structure.
Results: A total of 113 patients (47.8% Male, 52.2% Female) participated. The EFA identified a unidimensional structure for the Arabic ODI, with one factor explaining 45.8% of the total variance. All items had significant factor loadings, with loadings ranging from 0.48 (sleeping) to 0.84 (sex life and social life). The CFA confirmed this unidimensional structure, yielding good fit indices (χ²=49.53, P<0.04; TLI=0.96; CFI=0.97; RMSEA=0.06 (90% CI=0.07-0.10), SRMR=0.04). All ODI items exhibited significant positive loadings consistent with the expected correlation between the single latent variable (LBP-related disability) and the ODI items. A high error covariance was observed between items related to walking and standing.
Conclusion: The Arabic Oswestry Disability Index demonstrates sufficient structural validity as a unidimensional measure of disability in Arabic-speaking patients with low back pain. These findings support the continued use of the Oswestry Disability Index for disability assessment in clinical and research settings and support the validity of using one total score representing the single underlying latent construct.
