背景:颈部残疾指数(NDI),颈部疼痛的常见患者报告结局指标(PROM),在脊髓型颈椎病(CSM)患者术前缺乏对其心理测量特性的充分研究。
目的:本研究旨在通过对日本NDI进行探索性因素分析来解决这些差距。目标是双重的:(1)审查日本NDI的心理测量特性和内部一致性,(2)探索影响NDI的疼痛和麻木的特定区域。
方法:单中心观察性研究患者样本:100例术前CSM患者预后指标:采用NDI和数值评定量表(NRS)评估术前颈部残疾和各个身体部位的疼痛和麻木。
方法:收集人口统计学和临床特征,包括年龄,性别,身体质量指数,美国麻醉医师学会分类,吸烟状况,合并症,使用NRS的不同部位的疼痛和麻木,和NDI。为了评估NDI的心理测量特性和内部一致性,采用探索性因子分析(EFA)和克朗巴赫α系数。此外,通过多变量回归分析,研究了疼痛和麻木对NDI因素的影响.
结果:EFA确定了两个因素-身体和心理-突出了颈部相关残疾的双重性质。物理因素(性病β=0.724,p<0.001)与心理因素(std。β=0.409,p<0.001)。克伦巴赫的α系数为身体因素为0.831,精神因素为0.723,表明内部一致性很高。手麻木(性病。β=0.338,p<0.001)和颈部疼痛(std。β=0.202,p=0.035)是影响物理因子的显著变量,而麻木的手(std.β=0.485,p<0.001)和头部疼痛(std。β=0.374,p<0.001)影响精神因素。
结论:这项研究为CSM患者术前NDI的心理测量特性提供了有价值的见解。确定的因素强调了在术前护理中解决身体和感觉症状的重要性。
BACKGROUND: The Neck Disability Index (NDI), a common Patient-Reported Outcome Measure (PROM) for neck pain, lacks sufficient study on its psychometric properties in preoperative patients with cervical spondylotic myelopathy (CSM).
OBJECTIVE: This study aims to address these gaps by conducting an exploratory factor analysis of the Japanese NDI. The objectives are 2-fold: (1) to scrutinize the psychometric properties and internal consistency of the Japanese NDI, and (2) to explore the specific regions of pain and numbness influencing the NDI.
METHODS: A single-center observational study.
METHODS: A total of 100 preoperative patients with CSM.
METHODS: The NDI and Numerical Rating Scale (NRS) were employed to assess preoperative neck disability and pain and numbness in various body regions.
METHODS: Demographic and clinical characteristics were collected, encompassing age, sex, body mass index, American Society of Anesthesiologists classification, smoking status, comorbidities, pain and numbness at various sites using the NRS, and NDI. For evaluating the psychometric properties and internal consistency of the NDI, exploratory factor analysis (EFA) and Cronbach\'s α coefficient were utilized. Furthermore, the impact of pain and numbness on NDI factors was examined through multivariable regression analysis.
RESULTS: EFA identified 2 factors-Physical and Mental-highlighting the dual nature of neck-related disability. Physical factors (std.β=0.724, p<.001) exerted a stronger impact on NDI scores compared to Mental factors (std.β=0.409, p<.001). Cronbach\'s α coefficient was 0.831 for physical factors and 0.723 for mental factors, indicating a high level of internal consistency. Numbness in the hand (std.β=0.338, p<.001) and pain in the neck (std.β=0.202, p=.035) were significant variables influencing Physical factor, while numbness in the hand (std.β=0.485, p<.001) and pain in the head (std.β=0.374, p<.001) impacted Mental factor.
CONCLUSIONS: This study contributes valuable insights into the psychometric properties of the NDI in preoperative patients with CSM. The identified factors emphasize the importance of addressing both physical and sensory symptoms in preoperative care.
