评估两种常用的腰痛（LBP）残疾问卷的心理测量学特性，样本仅包括社区居住的老年人。单组重复测量设计。马里兰州和弗吉尼亚州的四个持续护理退休社区。107名社区居住男性和女性的便利样本（71.9%）年龄在62岁或62岁以上，目前患有LBP。所有参与者都完成了改良的奥斯韦斯特里残疾（mOSW）和魁北克背痛残疾（QUE）问卷，以及基线时的医疗结局调查简表36问卷。随访时，56名受试者完成了mOSW和QUE的信度评估，mOSW和QUE的重测信度非常好，组内相关系数分别为0.92（95%CI：0.86，0.95）和0.94（95%CI：0.90，0.97）。高疼痛严重程度和高水平功能限制的参与者在mOSW（P < 0.0001）和QUE（P < 0.001）量表上的得分高于其他参与者，这代表了两个量表的良好结构效度。mOSW的最小可检测变化阈值为10.66分，QUE为11.04分。两份问卷都有足够的量表宽度来准确测量患者状态的变化，当用于评估不同程度LBP的老年人的LBP相关残疾时，两份问卷似乎都具有良好的重测信度和良好的结构效度。两个问卷似乎都没有上级心理测量学特性;因此，奥斯韦斯特里和魁北克都可以推荐用于老年LBP患者。
To evaluate the psychometric properties of two commonly used low back pain (LBP) disability questionnaires in a sample solely comprising community-dwelling older adults.Single-group repeated measures design.Four continuing care retirement communities in Maryland and in Virginia.Convenience sample of 107 community-dwelling men and women (71.9%) aged 62 years or older with current LBP.All participants completed modified Oswestry Disability (mOSW) and Quebec Back Pain Disability (QUE) questionnaires, as well as the Medical Outcomes Survey Short-Form 36 questionnaire at baseline. At follow-up, 56 participants completed the mOSW and the QUE for reliability assessment.Test-retest reliability of the mOSW and QUE were excellent with intraclass correlation coefficients of 0.92 (95% confidence interval [CI]: 0.86, 0.95) and 0.94 (95% CI: 0.90, 0.97), respectively. Participants with high pain severity and high levels of functional limitation had higher scores on the mOSW (P < 0.0001) and QUE (P < 0.001) scales than other participants, which represents good construct validity for both scales. The threshold for minimum detectable change is 10.66 points for the mOSW and 11.04 points for the QUE. Both questionnaires had sufficient scale width to accurately measure changes in patient status.It appears that both questionnaires have excellent test-retest reliability and good construct validity when used to evaluate LBP-related disability for older adults with varying degrees of LBP. Neither questionnaire appears to have superior psychometric properties; therefore, both the Oswestry and Quebec can be recommended for use among geriatric patients with LBP.
