A large number of patients have chronic back pain, producing disability. Consequently, there is a need to validate instruments for pain measurement. The aim of this study was to determine the validity and reliability of the Oswestry Disability Scale for Low Back Pain in the population with chronic back pain in Cienfuegos.
The investigation consisted of the development of an instrument to validate the scale through content validity, construct validity and reliability analysis. The validation included linguistic and cultural adaptation of the instrument. The study was conducted at the Dr. Gustavo Aldereguía Lima University Hospital in Cienfuegos, Cuba, from September 2017 to October 2018. Systematic randomised sampling was used. The sample included 162 patients. The statistical analysis was performed with the SPSS statistical package.
The experts considered that the instrument should remain unchanged. Factorial analysis identified the presence of three intercorrelated factors that represented 63% of the total. A global Cronbach α of 0.801 was obtained and the temporal stability of the instrument was demonstrated.
The results confirm the validity and reliability of the Oswestry Disability Scale for Low Back Pain in the Cienfuegan population with chronic back pain.
大量患者患有慢性背痛，导致残疾。因此，需要验证疼痛测量工具。本研究的目的是确定奥斯特里残疾量表在西恩富戈斯慢性背痛人群中测量腰痛的有效性和可靠性。
该调查包括开发一种工具，通过内容效度、结构效度和可靠性分析来验证该量表。验证包括对该工具进行语言和文化适应性调整。该研究于2017年9月至2018年10月在古巴西恩富戈斯的古斯塔沃·阿尔德雷吉亚·利马大学医院进行。采用系统随机抽样。样本包括162名患者。使用SPSS统计软件包进行统计分析。
专家们认为该工具应保持不变。因子分析确定存在三个相互关联的因子，占总数的63%。获得了全局Cronbach α系数为0.801，并证明了该工具的时间稳定性。
结果证实了奥斯特里残疾量表在西恩富戈斯慢性背痛人群中测量腰痛的有效性和可靠性。
