A cross-sectional study.
Th aim of this study was to translate and cross-culturally adapt Copenhagen Neck Function Disability Scale into a Simplified Chinese version (CNFDS-C), and evaluate the reliability and validity of CNFDS-C in patients with nonspecific chronic neck pain.
The CNFDS is a reliable and valid evaluation instrument for chronic neck pain. However, Simplified Chinese version of CNFDS hasn't been validated.
A total of 150 participants were included in this study. Internal consistency was estimated according to Cronbach alpha. Test-retest reliability was assessed by intra-class correlation coefficient (ICC). Construct validity was analyzed by correlations between CNFDS-C and the Neck Disability Index (NDI), Visual Analogue Scale (VAS) as well as the short form (36) health survey (SF-36).
The original version of the CNFDS was cross-culturally adapted and translated into Simplified Chinese. CNFDS-C was indicated to have excellent reliability (Cronbach alpha = 0.810, ICC = 0.927). Moderate to substantial correlations between CNFDS-C and NDI (r = 0.642, P < 0.001), VAS (r = 0.581, P < 0.001), as well as Physical Function (r = -0.583, P < .001), Role Physical (r = -0.478, P < 0.001), Bodily Pain (r = -0.610, P < 0.001), and General Health (r = -0.439, P < 0.001) subscales of SF-36 were observed.
CNFDS-C was demonstrated to have acceptable reliability and validity in patients with nonspecific chronic neck pain, which could be recommended for patients in Chinese mainland.Level of Evidence: 3.
一项横断面研究。
本研究旨在将哥本哈根颈部功能障碍量表（Copenhagen Neck Function Disability Scale）翻译并跨文化适应为简体中文版（CNFDS-C），并评估其在非特异性慢性颈痛患者中的信度和效度。
CNFDS 是一种可靠且有效的慢性颈痛评估工具。然而，CNFDS 的简体中文版尚未得到验证。
本研究共纳入 150 名参与者。采用 Cronbach α 评估内部一致性。采用组内相关系数（intra-class correlation coefficient，ICC）评估重测信度。通过 CNFDS-C 与颈部残疾指数（Neck Disability Index，NDI）、视觉模拟量表（Visual Analogue Scale，VAS）以及健康调查简表 36 项（Short Form 36，SF-36）之间的相关性分析来评估结构效度。
CNFDS 经跨文化适应和翻译为简体中文后，形成了 CNFDS-C。CNFDS-C 具有极好的信度（Cronbach α=0.810，ICC=0.927）。CNFDS-C 与 NDI（r=0.642，P<0.001）、VAS（r=0.581，P<0.001）以及 SF-36 的生理功能（Physical Function，r=-0.583，P<0.001）、生理职能（Role Physical，r=-0.478，P<0.001）、躯体疼痛（Bodily Pain，r=-0.610，P<0.001）和总体健康（General Health，r=-0.439，P<0.001）子量表之间呈中度至高度相关。
CNFDS-C 在中国内地非特异性慢性颈痛患者中具有可接受的信度和效度，可推荐用于此类患者。
