Disputes exist regarding the psychometric properties of the Oswestry Disability Index (ODI). The present study was to examine the reliability, validity, and dimensionality of a Chinese version of the ODI version 2.1 in a sample of 225 adult orthopedic outpatients with chronic low back pain [mean age (SD): 40.7 (11.4) years].
We conducted reliability analysis, exploratory bifactor analysis, confirmatory factor analysis, and Mokken scale analysis of the ODI. To validate the ODI, we used the Short-Form 36 questionnaire (SF-36) and visual analog scale (VAS).
The reliability, and discriminant and construct validities of the ODI was good. The fit statistics of the unidimensional model of the ODI were inadequate. The ODI was a weak Mokken scale (H = 0.31).
The ODI was a reliable and valid scale suitable for measurement of disability in patients with low back pain. But the ODI seemed to be multidimensional that was against the use of the raw score of the ODI as a measurement of disability.
关于奥斯威斯利残疾指数（ODI）的心理测量特性存在争议。本研究旨在对225名患有慢性下腰痛的成年骨科门诊患者样本[平均年龄（标准差）：40.7（11.4）岁]，检验中文版ODI 2.1的信度、效度和维度。
我们对ODI进行了信度分析、探索性双因素分析、验证性因素分析和莫肯量表分析。为验证ODI，我们使用了简明健康状况调查问卷（SF - 36）和视觉模拟量表（VAS）。
ODI的信度、区分效度和结构效度良好。ODI单维模型的拟合统计量不充分。ODI是一个弱莫肯量表（H = 0.31）。
ODI是一个可靠且有效的量表，适用于测量下腰痛患者的残疾程度。但ODI似乎是多维的，这与将ODI原始分数用作残疾测量指标的做法相悖。
