Obesity has become a major worldwide public health issue. There is a need for tools to measure patient-reported outcomes. The Moorehead-Ardelt Quality of Life Questionnaire II (MA II) contains six items. The objective of this study was to translate the MA II into Chinese and validate it in patients with morbid obesity.
The MA II was translated into Chinese and back-translated into English by two language specialists to create the Taiwan version, which was validated by correlations with two other generic questionnaires of health-related quality of life (HRQOL), Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and World Health Organization Quality of Life (WHOQOL)-BREF Taiwan version. The convergent validity was accomplished by a series of Spearman rank correlations. Reliability of the MA II Taiwan version was determined by internal consistency obtained by Cronbach's alpha coefficient and test-retest reliability obtained by intraclass correlation coefficient.
One hundred subjects with morbid obesity were enrolled to test the MA II Taiwan version convergent validity and internal consistency. Test-retest studies (2 weeks apart) were applied to 30 morbidly obese patients. Satisfactory internal consistency was demonstrated by a Cronbach's alpha coefficient of 0.79. Good test-retest reliability was shown by intraclass correlations ranging from 0.73 to 0.91. The total sum of MA II scores was significantly correlated with all four domains of the WHOQOL-BREF and two major components of SF-36 (all correlations, p < 0.01; range, 0.44-0.64). All six MA II items showed significant correlations with each other (r = 0.34-0.69, p < 0.01), and the total sum of MA II scores was negatively correlated with body mass index (r = -0.31, p < 0.01), indicating a one-dimensional questionnaire of HRQOL.
The MA II Taiwan version is an obesity-specific questionnaire for QOL evaluation with satisfactory reliability and validity. It has the advantages of extensive evaluation for HRQOL, cross-cultural application, rapid completion, high response rates, and an advanced scoring system.
肥胖已成为全球主要的公共卫生问题。需要有工具来衡量患者报告的结果。Moorehead-Ardelt 生活质量问卷 II（MA II）包含六个项目。本研究的目的是将 MA II 翻译成中文，并在病态肥胖患者中进行验证。
MA II 由两位语言专家翻译成中文并回译为英文，创建了台湾版本，并通过与另外两个健康相关生活质量（HRQOL）的通用问卷的相关性进行验证，即医疗结果研究 36 项短式健康调查问卷（SF-36）和世界卫生组织生活质量（WHOQOL）-BREF 台湾版本。通过一系列斯皮尔曼等级相关来实现收敛有效性。MA II 台湾版本的可靠性通过 Cronbach 的 alpha 系数获得的内部一致性和通过组内相关系数获得的测试-重测可靠性来确定。
纳入 100 例病态肥胖患者来测试 MA II 台湾版本的收敛有效性和内部一致性。对 30 例病态肥胖患者进行了 2 周的测试-重测研究。Cronbach 的 alpha 系数为 0.79，表明内部一致性令人满意。组内相关性在 0.73 至 0.91 之间，表明重测可靠性良好。MA II 总分与 WHOQOL-BREF 的所有四个领域和 SF-36 的两个主要成分均显著相关（所有相关性，p < 0.01；范围为 0.44-0.64）。MA II 的所有六个项目彼此之间均显示出显著相关性（r = 0.34-0.69，p < 0.01），并且 MA II 总分与体重指数呈负相关（r = -0.31，p < 0.01），表明该问卷是一种 HRQOL 的一维问卷。
MA II 台湾版本是一种专门用于评估肥胖患者生活质量的问卷，具有良好的信度和效度。它具有广泛评估 HRQOL、跨文化应用、快速完成、高响应率和先进评分系统的优点。
