BACKGROUND
The Michigan Hand Questionnaire (MHQ) is widely used to assess the hand/wrist conditions. We translated the original version into Thai (Thai MHQ) and evaluated its psychometric properties.
METHODS
After receiving permission, the original MHQ was translated and cross-culturally adapted to Thai following standard guidelines. Two hundred and seventeen patients who had hand/wrist injuries or disorders were included in the study. Internal consistency was evaluated using Cronbach's alpha. Test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). Spearman's rank correlation among the subscales of Thai MHQ, Thai DASH and Thai EQ-5D-5L and also confirmatory factor analysis (CFA) were used to explore construct validity. The standardized response mean (SRM) was used to evaluate the responsiveness of the Thai MHQ.
RESULTS
All subscales showed an acceptable Cronbach's alpha (0.79-0.98). The test-retest reliability of each subscale was good (ICC = 0.83-0.95). In related dimensions, strong correlation was demonstrated between the Activities of daily living subscale of the Thai MHQ and the Common activities subscale in the Thai DASH (r = 0.77, P < 0.0001). For unrelated dimensions, a weak correlation was found between the Aesthetics subscale in the Thai MHQ and the Mobility subscale in the Thai EQ-5D-5L (r = - 0.13, P = 0.05). The Thai MHQ had strong correlation with Thai DASH (r = - 0.79, P < 0.0001) and Thai EQ-5D-5L (r = 0.63, P < 0.0001). CFA showed that the 6-factor model demonstrated an acceptable fit to the data. The SRM of the Thai MHQ was 0.78, indicating relatively large responsiveness. The MIC of Thai MHQ using distribution methods (SEM) was 5.2.
CONCLUSIONS
The Thai MHQ provides adequate internal consistency in all subscales as well as good construct validity and reliability for Thai patients and a relatively large standardized response mean at 2 months after treatment.
背景
密歇根手问卷（MHQ）被广泛用于评估手部/腕部状况。我们将原始版本翻译为泰语（泰语 MHQ），并按照标准指南进行了跨文化适应性调整。本研究纳入了 217 名手部/腕部受伤或患病的患者。采用 Cronbach's alpha 评估内部一致性。采用组内相关系数（ICC）分析测试-重测信度。使用 Spearman 秩相关分析泰语 MHQ 的子量表与泰语 DASH 和泰语 EQ-5D-5L 之间的关系，以及验证性因子分析（CFA）来探索结构效度。使用标准化反应均值（SRM）评估泰语 MHQ 的反应度。
结果
所有子量表的 Cronbach's alpha 值均在可接受范围内（0.79-0.98）。每个子量表的测试-重测信度均较好（ICC=0.83-0.95）。在相关维度方面，泰语 MHQ 的日常生活活动子量表与泰语 DASH 的常见活动子量表之间存在较强的相关性（r=0.77，P<0.0001）。在不相关维度方面，泰语 MHQ 的美学子量表与泰语 EQ-5D-5L 的活动能力子量表之间存在较弱的相关性（r=-0.13，P=0.05）。泰语 MHQ 与泰语 DASH（r=-0.79，P<0.0001）和泰语 EQ-5D-5L（r=0.63，P<0.0001）具有较强的相关性。CFA 显示，6 因子模型对数据具有较好的拟合度。泰语 MHQ 的 SRM 为 0.78，表明反应度较大。使用分布法（SEM）的泰语 MHQ 的 MIC 为 5.2。
结论
泰语 MHQ 对泰国患者的所有子量表均具有足够的内部一致性和良好的结构有效性和可靠性，且在治疗后 2 个月时具有较大的标准化反应均值。
