The Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) was developed to resolve problems associated with the original evaluation of cervical myelopathic patients. The aim of this study was to translate the JOACMEQ into Thai as per international recommendations, and to test its reliability and validity in the Thai context
The JOACMEQ was translated into Thai, using international guidelines. Cervical myelopathy patients (n = 70; 31 males) were asked to complete the Thai version JOACMEQ twice (4 weeks apart). Test-retest reliability was analyzed using the intra-class correlation coefficient (ICC). Internal consistencies were analyzed using Cronbach's alpha, while the construct validity was compared with the Thai version modified SF-36; using the Spearman's rank correlation coefficient.
The Thai JOACMEQ produced good reliability (i.e., the ICC was >0.9 in 2 parameters and >0.8 in one). Overall the Cronbach's α for the 24 questions showed very high internal consistency (Cronbach's α > 0.8) and almost all Cronbach's α showed satisfactory internal consistency except for bladder function. The Spearman's rank correlation for all the JOACMEQ parameters had a positive correlation with all Thai SF 36 subscales, especially the quality of life parameter, which showed a strong correlation with all SF-36 subscales.
The Thai version of the JOACMEQ had satisfactory internal consistency and test-retest reliability: it also had good construct validity. It can therefore be used as a reliable tool for assessing quality of life for cervical myelopathy patients in Thailand.
日本矫形外科学会颈椎病评估问卷（JOACMEQ）旨在解决与颈椎病患者原始评估相关的问题。本研究的目的是按照国际建议将JOACMEQ翻译成泰语，并在泰国背景下测试其信度和效度。
按照国际指南将JOACMEQ翻译成泰语。邀请颈椎病患者（n = 70；男性31例）分两次（间隔4周）完成泰语版JOACMEQ。使用组内相关系数（ICC）分析重测信度。使用克朗巴哈系数分析内部一致性，同时将结构效度与泰语版改良SF-36进行比较；使用斯皮尔曼等级相关系数。
泰语版JOACMEQ具有良好的信度（即2个参数的ICC>0.9，1个参数的ICC>0.8）。总体而言，24个问题的克朗巴哈系数显示出非常高的内部一致性（克朗巴哈系数>0.8），除膀胱功能外，几乎所有克朗巴哈系数均显示出令人满意的内部一致性。JOACMEQ所有参数的斯皮尔曼等级相关性与所有泰语SF 36子量表均呈正相关，尤其是生活质量参数，与所有SF-36子量表均呈强相关。
泰语版JOACMEQ具有令人满意的内部一致性和重测信度：其结构效度也良好。因此，它可以作为评估泰国颈椎病患者生活质量的可靠工具。
