To examine the validity, reliability, and responsiveness of 3 commonly used questionnaires for assessing physical function (ie, Oswestry Disability Index [ODI], Quebec Back Pain Disability Scale [QBPDS], and Roland-Morris Disability Questionnaire [RMDQ]) in older patients undergoing chiropractic care for low back pain (LBP).
Head-to-head clinimetric comparison.
Patients completed the ODI, QBPDS, and RMDQ at baseline and after 2 weeks of treatment. Reliability was evaluated for internal consistency (Cronbach ), test-retest reliability (interclass correlation coefficient [ICC]), and measurement error (standard error of measurement and smallest detectable change [SDC]). Structural validity was evaluated through unidimensional confirmatory factor analysis, and construct validity was investigated by a priori hypotheses with other measures. Responsiveness was evaluated by testing a priori hypotheses using data at baseline and at 2-week follow-up.
Two hundred fourteen patients (53% males and 47% females) with a mean age of 66.2 years (standard deviation = 7.8 years) were included, of which 193 patients completed the 2-week follow-up for our responsiveness analysis. The RMDQ, ODI, and QBPDS showed sufficient internal consistency (Cronbach of .89, .86, and .94, respectively) and test-retest reliability (ICC[2,1] of 0.85, 0.89, and 0.84, respectively). The SDC for the RMDQ was 6.9, for the ODI was 19.1, and for the QBPDS was 23.6, which are values larger than the minimal important change. None of the measures met all criteria for sufficient structural validity, but the RMDQ and ODI exhibited a partial unidimensional fit. The questionnaires had sufficient construct validity and responsiveness.
The ODI, QBPDS, and RMDQ have similar measurement properties in older adults with LBP. .
考察三种常用于评估躯体功能的问卷（即 Oswestry 功能障碍指数 [ODI]、魁北克腰痛残疾量表 [QBPDS] 和 Roland-Morris 残疾问卷 [RMDQ]）在接受脊骨疗法治疗腰痛（LBP）的老年患者中的有效性、可靠性和反应度。
头对头临床计量比较。
患者在基线时和治疗 2 周后完成 ODI、QBPDS 和 RMDQ。通过内部一致性（Cronbach ）、重测信度（组内相关系数 [ICC]）和测量误差（测量标准误差和最小可检测变化 [SDC]）评估可靠性。通过单维验证性因子分析评估结构效度，并通过与其他测量方法的先验假设检验进行构念效度研究。通过使用基线和 2 周随访时的数据检验先验假设来评估反应度。
纳入了 214 名患者（53%为男性，47%为女性），平均年龄为 66.2 岁（标准差=7.8 岁），其中 193 名患者完成了 2 周随访，用于我们的反应度分析。RMDQ、ODI 和 QBPDS 显示出足够的内部一致性（Cronbach 分别为.89、.86 和.94）和重测信度（ICC[2,1]分别为 0.85、0.89 和 0.84）。RMDQ 的 SDC 为 6.9，ODI 的 SDC 为 19.1，QBPDS 的 SDC 为 23.6，这些值均大于最小临床重要变化值。没有任何一种测量方法都满足充分的结构效度的所有标准，但 RMDQ 和 ODI 显示出部分的单维拟合。这些问卷具有足够的构念效度和反应度。
在患有 LBP 的老年患者中，ODI、QBPDS 和 RMDQ 具有相似的测量特性。
