目的：评估修订的偏头痛生活质量问卷(MSQ)(2.1版)((C)1992,1996,1998 Glaxo Wellcome Inc.)的测量特性、信度和效度。背景-MSQ是一种疾病特异性的生活质量工具，有三个假设量表，已经开发、测试和修订。方法-本研究采用多中心、非药物、前瞻性、平行分组、准实验设计。偏头痛患者在门诊头痛专科诊所被招募，并在基线、4周和12周接受MSQ、医学结果研究36项健康调查(SF-36)和偏头痛症状问卷调查。评估内部一致性(Cronbachα)和4周重测再现性(组内相关系数)以评估信度。结构效度评估采用Campbell和Fiske多特质多方法的适应性，并将MSQ得分与症状测量相关联。结果：共有267名受试者参加试验。总评分量表的标准都达到了。三个维度的内部一致性系数在0.86~0.96之间，组内相关系数在0.57~0.63之间。正如预期的那样，MSQ维度与SF-36的两个组成部分得分有低到中等的相关性，与偏头痛症状有适度到中等的相关性。结论-MSQ是评估偏头痛患者生活质量的可靠工具，这些项目可以在不考虑重量的情况下求和。MSQ已经证明了结构效度的证据。
Objective.-To assess the scaling properties, reliability, and validity of the revised Migraine-Specific Quality of Life Questionnaire (MSQ) (Version 2.1) ((C) 1992, 1996, 1998 Glaxo Wellcome Inc.).Background.-The MSQ is a disease-specific, quality-of-life instrument with three hypothesized scales that has been developed, tested, and revised.Methods.-The study used a multicenter, nondrug, prospective, parallel group, quasi-experimental design. Patients with migraine were recruited at outpatient headache specialty practices and were administered the MSQ, the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), and migraine symptom questionnaires at baseline, 4 weeks, and 12 weeks. Internal consistency (Cronbach alpha) and 4-week test-retest reproducibility (intraclass correlation coefficients) were estimated to assess reliability. Construct validity was assessed using an adaptation of the Campbell and Fiske multitrait-multimethod approach and by correlating MSQ scores with symptom measures.Results.-A total of 267 subjects enrolled in the trial. The criteria for summated rating scales were all met. The internal consistency coefficients ranged from 0.86 to 0.96, and the intraclass correlation coefficients ranged from 0.57 to 0.63 across the three dimensions. As anticipated, the MSQ dimensions had low-to-modest correlations with the two component scores of the SF-36 and were modestly to moderately correlated with migraine symptoms.Conclusions.-The MSQ is a reliable instrument in the assessment of quality of life for patients with migraine with items that can be summed without weights. The MSQ has demonstrated evidence of construct validity.
