To evaluate the reliability and validity of the Thai version of the neck disability index (NDI) in neck pain patients.
The NDI was translated into Thai. The translation strategy used international standards. Forty-six Thai patients with neck pain were included in the present study. Thai version NDI, short form-36 (SF-36) and visual analogue scale (VAS) were completed by all subjects, twice, one week apart. The reliability and validity were subsequently analyzed.
Intraclass correlation coefficient score for test retest reliability was 0.986. Cronbach's alpha for internal consistency was calculated as 0.925. For concurrent validity, the relation between NDI and VAS was investigated, the r value was 0.886 (p < 0.001). For construct validity, the relation between NDI and the Thai version of SF-36 was -0.427. The mental health component was highest correlated with NDI.
The Thai version of NDI is a valid and reliable measurement method for evaluating neck pain disability.
评估泰语版颈部功能障碍指数（NDI）在颈部疼痛患者中的可靠性和有效性。
将NDI翻译成泰语。翻译策略采用国际标准。本研究纳入了46名泰国颈部疼痛患者。所有受试者均完成泰语版NDI、简短健康调查问卷36项简表（SF-36）和视觉模拟评分法（VAS），间隔一周进行两次。随后分析其可靠性和有效性。
重测信度的组内相关系数评分为0.986。内部一致性的Cronbach's α系数计算为0.925。对于同时效度，研究了NDI与VAS之间的关系，r值为0.886（p<0.001）。对于结构效度，NDI与泰语版SF-36之间的关系为-0.427。心理健康分量表与NDI的相关性最高。
泰语版NDI是评估颈部疼痛功能障碍的一种有效且可靠的测量方法。
