A Thai-version of the Migraine Specific Quality of Life Questionnaire (MSQ 2.1) is available, but a qualified questionnaire used specifically for disability assessment was not available. The most relevant practical disability assessment tested during this study was the Migraine Disability Assessment (MIDAS) Questionnaire.
To test the concurrent validity, test-retest reliability, and internal consistency of a Thai-version MIDAS questionnaire, and factors to predict disability in people with migraine.
We conducted the present prospective study at a tertiary care teaching hospital in Bangkok. The original English MIDAS Questionnaire was translated into Thai with back-translation into English and the language equivalence was assessed. The Thai-version MIDAS Questionnaire was tested for concurrent validity, test-retest reliability, and internal consistency, and factors including duration of migraine history, migraine characteristics, and comorbidity were assessed for the ability to predict migraine-related disability of migraineurs.
Of the 58 participants, 31 were eligible to be included. The validity of the Thai-version questionnaire between the MIDAS total score and the mean headache severity (question B), the mean pain duration per attack, and the mean pain numerical rating scale (NRS) score were moderately correlated with a Spearman correlation coefficient range 0.42-0.58. The test-retest reliability of MIDAS grade had a weighted κ of 0.66, and for individual questions of the MIDAS total score, questions A and B assessed by intraclass correlation coefficients ranged 0.89-0.98. The internal consistency had a Cronbach α of 0.98. The mean pain NRS score in the past 3 months was an independent predictive factor for migraine-related disability.
The Thai-version MIDAS Questionnaire has moderate concurrent validity, acceptable internal consistency, and excellent test-retest reliability. It would be helpful to assess clinical outcomes. Future study with a standardized translation process for the Thai-version questionnaire and a larger sample size is warranted to confirm internal consistency and determine all probable predictive factors for migraine-related disability.
有泰语版的偏头痛特异性生活质量问卷（MSQ 2.1），但尚无专门用于残疾评估的合格问卷。本研究中测试的最相关实用残疾评估工具是偏头痛残疾评估（MIDAS）问卷。
测试泰语版MIDAS问卷的同时效度、重测信度和内部一致性，以及预测偏头痛患者残疾的因素。
我们在曼谷的一家三级护理教学医院进行了这项前瞻性研究。将原始英文MIDAS问卷翻译成泰语，再回译成英文，并评估语言等效性。对泰语版MIDAS问卷进行同时效度、重测信度和内部一致性测试，并评估偏头痛病史时长、偏头痛特征和合并症等因素预测偏头痛患者偏头痛相关残疾的能力。
58名参与者中，31名符合纳入条件。泰语版问卷的MIDAS总分与平均头痛严重程度（问题B）、每次发作的平均疼痛时长以及平均疼痛数字评定量表（NRS）得分之间的效度呈中度相关，Spearman相关系数范围为0.42 - 0.58。MIDAS分级的重测信度加权κ为0.66，对于MIDAS总分的各个问题，问题A和B通过组内相关系数评估，范围为0.89 - 0.98。内部一致性的Cronbach α为0.98。过去3个月的平均疼痛NRS得分是偏头痛相关残疾的独立预测因素。
泰语版MIDAS问卷具有中度同时效度、可接受的内部一致性和出色的重测信度。这将有助于评估临床结果。未来有必要对泰语版问卷采用标准化翻译流程并扩大样本量进行研究，以确认内部一致性并确定偏头痛相关残疾的所有可能预测因素。
