Morbid obesity adversely affects quality of life. The assessment of health-related quality of life (HRQoL) needs specific measuring instruments. The Moorehead-Ardelt Quality-of-Life Questionnaire II (MA II) is an obesity-specific instrument widely used in bariatric surgery. The objective of this study was to translate and validate the MA II in Greek language. The study included the translation of the MA II followed by cross-validation with the Greek version of 36-item Short Form Health Survey (SF-36) and a Visual Analogue Scale (VAS) in subjects visiting an obesity clinic. Internal consistency was indicated by Cronbach's alpha coefficient and test-retest reliability by intraclass correlation coefficient (ICC). Construct validity was studied using Pearson's correlations between the MA II, the SF-36 and the VAS. A total of 175 patients were enrolled in the study. Test-retest analysis was applied to 40 patients with a 15-day interval. A very good internal consistency with Cronbach's alpha coefficient of 0.85 was shown. Excellent test-retest reliability was observed with an overall ICC of 0.981. Significant correlations between the Greek MA II and the other instruments as well as of each item of the MA II with the scores of SF-36 and the VAS indicated high construct and convergent validity. A negative correlation between the translated MA II total score and BMI confirmed high clinical validity. The Greek version of the MA II questionnaire has been generated and shown to be valid and reliable in measuring HRQoL in morbidly obese patients before and after bariatric surgery.
病态肥胖会对生活质量产生不利影响。健康相关生活质量（HRQoL）的评估需要特定的测量工具。Moorehead-Ardelt 生活质量问卷 II（MA II）是一种广泛用于减重手术的肥胖特异性工具。本研究的目的是将 MA II 翻译成希腊语并进行验证。该研究包括 MA II 的翻译，然后在肥胖诊所就诊的患者中使用希腊版 36 项简短健康调查问卷（SF-36）和视觉模拟量表（VAS）进行交叉验证。内部一致性用 Cronbach's alpha 系数表示，测试-重测可靠性用组内相关系数（ICC）表示。结构有效性通过 MA II、SF-36 和 VAS 之间的 Pearson 相关研究。共纳入 175 例患者，其中 40 例进行了 15 天的测试-重测分析。Cronbach's alpha 系数为 0.85，表明具有非常好的内部一致性。总体 ICC 为 0.981，观察到良好的测试-重测可靠性。希腊 MA II 与其他仪器之间以及 MA II 的每个项目与 SF-36 和 VAS 评分之间存在显著相关性，表明具有较高的结构和收敛有效性。翻译后的 MA II 总分与 BMI 之间的负相关证实了其具有较高的临床有效性。希腊版 MA II 问卷已生成，并且在肥胖症患者减重手术前后测量 HRQoL 方面表现出有效性和可靠性。
