Abstract

STUDY DESIGN

Observational prospective study.

OBJECTIVE

Validate the Spanish version of the Neck Disability Index (NDI).

SUMMARY OF BACKGROUND DATA

The NDI is the most widely used neck pain scale in the largest number of populations and has been validated most often against multiple measurements of function, pain, and clinical signs and symptoms.

METHODS

The Spanish version of the NDI was administered 2 or 3 times to 175 individuals with neck pain (including those requesting or not requesting specific healthcare at a given time and those with acute and subacute/chronic nonspecific or post-traumatic neck pain). After establishing the factorial structure by extracting the main components, the internal consistency was assessed with the Cronbach alpha method, the test-retest reliability was assessed with the Bland-Altman plot and the intraclass correlation coefficient methods, and the validity was established by calculating Pearson correlation coefficient with pain visual analogue scale values and with Northwick Park Neck Pain Questionnaire (Spanish version) values. Sensitivity to change was estimated while comparing the mean difference between the first application of the NDI score and the one after the treatment in the patients who improved, felt the same, or worsened.

RESULTS

A single factor explained 51.6% of the variance, the Cronbach alpha score was 0.89, the intraclass correlation coefficient was 0.98, the Pearson correlation coefficient with pain visual analogue scale was r = 0.65 and with Northwick Park Neck Pain Questionnaire was r = 0.89. In the subgroup of 147 subjects in whom the sensitivity to change was studied, those who reported an improvement in neck pain showed a decrease in the NDI score of 8.20, those who felt the same showed a decrease of 0.23, and those who felt worse showed an increase of 5.55.

CONCLUSION

This first Spanish version of the Neck Disability Index is reliable, valid, and sensitive to change.

验证颈椎残障指数（NDI）的西班牙语版本。

背景数据概要

NDI 是最广泛应用于颈椎疼痛人群的量表，也是针对多项功能、疼痛以及临床体征和症状进行最常验证的量表。

方法

175 名颈椎疼痛患者（包括当时要求或不要求特定医疗护理的患者，以及急性、亚急性/慢性非特异性或创伤后颈椎疼痛患者）接受 2 或 3 次 NDI 西班牙语版本的测试。通过提取主要成分确定因子结构后，采用 Cronbach alpha 方法评估内部一致性，采用 Bland-Altman 图和组内相关系数方法评估测试-重测信度，采用计算 NDI 评分首次应用与治疗后之间均值差异的方法评估其对变化的敏感性，同时在疼痛视觉模拟评分值和 Northwick Park 颈椎疼痛问卷（西班牙语版本）值方面进行 Pearson 相关系数分析。

结果

单一因素解释了 51.6%的方差，Cronbach alpha 评分为 0.89，组内相关系数为 0.98，疼痛视觉模拟评分的 Pearson 相关系数为 r = 0.65，Northwick Park 颈椎疼痛问卷为 r = 0.89。在 147 名研究变化敏感性的亚组患者中，那些报告颈椎疼痛改善的患者 NDI 评分下降了 8.20，那些感觉相同的患者下降了 0.23，那些感觉恶化的患者增加了 5.55。
