Cross-cultural adaptation and cross-sectional psychometric testing in a convenience sample of patients with neck pain.
To translate and cross-culturally adapt the Neck Disability Index (NDI) into a Taiwanese version and to assess the psychometric properties.
The Taiwanese NDI has not been developed or validated.
The NDI was first translated and culturally adapted to the Taiwanese version. The test-retest reliability within 1 week was examined (n = 32). The factor structure was assessed by confirmatory factor analysis (n = 137). The construct validity was assessed by examining the relationship between the NDI and other well-known measures (n = 137).
The Taiwanese version was successfully translated and cross-culturally adapted. The internal consistency was excellent, with Cronbach α = 0.89. High test-retest reliability was demonstrated with intraclass correlation coefficients of 0.87. The minimal detectable change was 8.74. The two-factor model (pain and function factors) was better than the one-factor model, with higher factor loadings and better goodness-of-fit statistics. The convergent validity was supported by moderate correlation of the pain factor with the Visual Analogue Scale (|rho| = 0.45), and high correlation of the function factor with the physical component summary of the Short-From 36 (SF-36) (|rho| = 0.60).
The Taiwanese NDI is a reliable and valid disease-specific measure for assessment of pain and functional status in patients with neck pain.
在颈痛患者的便利样本中进行跨文化适应性和横断面心理测量测试。
将 Neck Disability Index（NDI）翻译并跨文化适应为繁体中文版，并评估其心理测量特性。
尚未开发或验证繁体中文版的 NDI。
首先将 NDI 翻译成繁体中文版并进行文化适应性调整。在 1 周内进行了测试-重测信度测试（n=32）。通过验证性因子分析评估了因子结构（n=137）。通过检查 NDI 与其他知名测量方法之间的关系评估了结构有效性（n=137）。
成功地翻译和跨文化适应了繁体中文版。内部一致性非常好，Cronbach α=0.89。高测试-重测可靠性，组内相关系数为 0.87。最小可检测变化为 8.74。双因素模型（疼痛和功能因素）优于单因素模型，具有更高的因子负荷和更好的拟合优度统计数据。疼痛因素与视觉模拟量表（|rho|=0.45）之间的中度相关性以及功能因素与简短 36 项健康调查（SF-36）的身体成分摘要（|rho|=0.60）之间的高度相关性支持了收敛有效性。
繁体中文版 NDI 是一种可靠且有效的疾病特异性测量工具，可用于评估颈痛患者的疼痛和功能状态。
