背景：SarOoL是一份针对肌肉减少症的生活质量问卷，于2015年开发，并已被翻译成多种语言。引入乌克兰新版本问卷的主要原因是为了衡量肌肉减少症患者在其文化和价值体系背景下对其生活地位的看法。方法：采用前向-后向法翻译问卷，并进行前测。验证性研究共招募了49名参与者。骨骼肌减少症是根据石井试验诊断的。验证分析包括辨别力、内部一致性、下限和上限效应、结构效度和重测信度。我们将SarQoL问卷与简表36和EuroQoL-5维度进行了比较。结果：49名参与者中有28名被归类为可能的肌肉减少症。他们的生活质量明显较低（总分58.43 +/- 17.13比69.89 +/- 13.31;p=0.014）。内部一致性很好（alpha=0.898），没有一个域对问卷的同质性产生不成比例的影响。聚合构念效度也得到了证实。结果显示了近乎完美的重测信度。结论：第一份乌克兰语版本的问卷与现有的英文原版问卷相当。
Background: The SarOoL, a quality-of-life questionnaire specific to sarcopenia, was developed in 2015 and has since been translated into a number of other languages. The main reason to introduce this new Ukrainian version of the questionnaire was to measure sarcopenic individuals' perceptions regarding their positions in life in the context of their culture and value systems. Methods: The questionnaire was translated using aforward-backward approach with a pre-test. A total of 49 participants were recruited for the validation study. Sarcopenia was diagnosed according to the Ishii test. The validation analyses included discriminative power, internal consistency, floor and ceiling effects, construct validity, and test-retest reliability. We compared the SarQoL questionnaire to the Short-Form 36 and the EuroQoL-5 Dimensions. Results: A total of 28 participants out of 49 were categorized as probably sarcopenic. They had a significantly lower quality of life (overall score 58.43 +/- 17.13 vs. 69.89 +/- 13.31; p=0.014). The internal consistency was excellent (alpha=0.898), with none of the domains showing a disproportionate influence on the homogeneity of the questionnaire. Convergent construct validity was also confirmed. The results indicated a near-perfect degree of test-retest reliability. Conclusions: The first Ukrainian version of the questionnaire is equivalent to the available original English version.
