Reliable and valid measurement tools are crucial for clinical practice in chronic nonspecific neck pain (CNSNP). The Copenhagen Neck Functional Disability Scale (CNFDS) is a widely used scale in neck pain assessment and has its unique advantages, but it is not available for patients with CNSNP in southern China.
To develop the simplified Chinese version of CNFDS (CNFDS-SC) cross-culturally and to investigate its measurement properties in patients with CNSNP.
Cross-sectional study.
Validation of neck pain measurement scale in southern China.
One hundred five patients with CNSNP.
Not applicable.
Internal consistency and test-retest reliability were evaluated using Cronbach's alpha and intraclass correlation coefficient (ICC), respectively. Construct validity and structural validity were validated by hypothesis testing and exploratory factor analysis, respectively. Internal and external responsiveness were validated. Interpretability was revealed by the standard error of measurement (SEM) and smallest detectable change (SDC).
Internal consistency (Cronbach's alpha = 0.77 for first test and 0.84 for retest) and test-retest reliability (ICC = 0.95) were satisfactory. CNFDS-SC scores showed strong correlations with the numeric rating scale (NRS), the Neck Disability Index (NDI), and the Northwick Park Neck Pain Questionnaire (NPQ) scores (r = 0.652, 0.763, and 0.719, respectively; p < .001). Factor analysis revealed a one-factor structure of the scale. Regarding responsiveness, the standardized response mean (SRM) and the Guyatt's responsiveness index (GRI) were 1.29 and 2.12, respectively. CNFDS-SC change scores showed good correlations with the anchoring question (r = 0.619, p < .001), NDI (r = 0.439, p = .001), and NPQ (r = 0.438 p = .001) change scores; the area under the receiver-operating characteristic (ROC) curve was 0.89 (p < .001). The SEM and SDC were 0.93 and 2.57, respectively. No floor or ceiling effect and no missing items were observed.
The CNFDS-SC was demonstrated with adequate reliability, validity, responsiveness, and interpretability. The CNFDS-SC could be an effective tool for the clinical assessment of patients with CNSNP in southern China.
可靠且有效的测量工具对于慢性非特异性颈部疼痛（CNSNP）的临床实践至关重要。哥本哈根颈部功能障碍量表（CNFDS）是颈部疼痛评估中广泛使用的量表，具有独特优势，但在中国南方的CNSNP患者中无法使用。
跨文化开发CNFDS的简体中文版（CNFDS-SC），并研究其在CNSNP患者中的测量特性。
横断面研究。
中国南方颈部疼痛测量量表的验证。
105例CNSNP患者。
不适用。
分别使用Cronbach's α系数和组内相关系数（ICC）评估内部一致性和重测信度。分别通过假设检验和探索性因子分析验证结构效度和构建效度。验证内部和外部反应度。通过测量标准误（SEM）和最小可检测变化（SDC）揭示可解释性。
内部一致性（首次测试Cronbach's α = 0.77，重测为0.84）和重测信度（ICC = 0.95）令人满意。CNFDS-SC得分与数字评定量表（NRS）、颈部功能障碍指数（NDI）和诺斯威克公园颈部疼痛问卷（NPQ）得分呈强相关（分别为r = 0.652、0.763和0.719；p <.001）。因子分析揭示该量表具有单因子结构。关于反应度，标准化反应均值（SRM）和盖亚特反应指数（GRI）分别为1.29和2.12。CNFDS-SC变化得分与锚定问题（r = 0.619，p <.001）、NDI（r = 0.439，p =.001）和NPQ（r = 0.43８，p =.001）变化得分具有良好相关性；受试者工作特征（ROC）曲线下面积为0.89（p <.001）。SEM和SDC分别为0.93和2.57。未观察到地板效应或天花板效应，也未发现缺失项目。
CNFDS-SC具有足够的信度、效度、反应度和可解释性。CNFDS-SC可能是中国南方CNSNP患者临床评估的有效工具。
