The Moorehead-Ardelt II (MA-II) questionnaire is the most frequently applied instrument to assess quality of life (QoL) in bariatric surgery patients. Our aim was to validate the Czech, German, Italian, and Spanish version of the MA-II.
A total of 893 patients were enroled in a prospective cross-sectional European study. Two thirds of the patients(n = 591) were postsurgical cases. In addition to demographicand clinical data, QoL data was collected using the MA-II questionnaire, the EuroQoL-5D (EQ-5D), and the Short Form 36 Health Survery (SF-36). Statistical parameters for contingency (Cronbach's alpha), construct and criterion validity(Pearson's r), and responsiveness (standardised effect sizes) were calculated for each language version.
In the different languages, Cronbach's alpha ranged from 0.817 to 0.885 for the MA-II. These values were higher than those obtained for the SF-36 (0.418-0.607). The MA-II was well correlated to the EQ-5D (r = 0.662) and to 3 of the 8 health domains of the SF-36 (0.615, 0.548, and 0.569 for physical functioning,physical role, and general health, respectively). As expected, there was a negative correlation between the MA-II and the BMI (r = -0.404 for all patients), but no significant correlation with age was found.When comparing both the heaviest and the lightest third of the patients, mean responsiveness was higher for the MA-II (-1.138) than for the domains of the SF-36 (range -0.111 to -1.070) and the EQ-5D (-0.874).
The Czech, German, Italian, and Spanish version of the MA-II questionnaire are valid instruments and should be preferred to generic questionnaires as they provide better responsiveness.
Moorehead-Ardelt II（MA-II）问卷是评估减重手术患者生活质量（QoL）最常用的工具。我们的目的是验证捷克语、德语、意大利语和西班牙语版本的 MA-II。
一项前瞻性的欧洲研究共纳入了 893 名患者。其中三分之二的患者（n=591）为术后患者。除了人口统计学和临床数据外，还使用 MA-II 问卷、欧洲五维健康量表（EQ-5D）和健康调查简表 36 项（SF-36）收集了 QoL 数据。为每个语言版本计算了一致性（Cronbach's alpha）、结构和标准有效性（Pearson's r）和反应性（标准化效应大小）的统计参数。
在不同的语言中，MA-II 的 Cronbach's alpha 范围为 0.817 至 0.885。这些值高于 SF-36（0.418-0.607）。MA-II 与 EQ-5D 高度相关（r=0.662），与 SF-36 的 8 个健康领域中的 3 个相关（身体功能、身体角色和总体健康，分别为 0.615、0.548 和 0.569）。正如预期的那样，MA-II 与 BMI 呈负相关（所有患者 r=-0.404），但与年龄无显著相关性。当比较患者中最重和最轻的三分之一时，MA-II 的平均反应性（-1.138）高于 SF-36 各领域（范围为-0.111 至-1.070）和 EQ-5D（-0.874）。
捷克语、德语、意大利语和西班牙语版本的 MA-II 问卷是有效的工具，应优先于通用问卷，因为它们提供了更好的反应性。
