BACKGROUND
The SarQoL, 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 a forward-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 (α=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.
背景
SarQoL是一种专门针对肌肉减少症的生活质量问卷，于2015年编制完成，此后已被翻译成多种其他语言。引入该问卷乌克兰语新版本的主要原因是，在其文化和价值体系背景下，衡量肌肉减少症患者对自身生活状况的看法。
方法
采用前后翻译法并进行预测试对问卷进行翻译。共有49名参与者被招募用于验证研究。根据石井测试诊断肌肉减少症。验证分析包括区分能力、内部一致性、地板效应和天花板效应、结构效度以及重测信度。我们将SarQoL问卷与简短健康调查36项量表和欧洲五维健康量表进行了比较。
结果
49名参与者中有28名被归类为可能患有肌肉减少症。他们的生活质量显著较低（总分58.43±17.13对69.89±13.31；p=0.014）。内部一致性良好（α=0.898），各领域对问卷同质性均未显示出不成比例的影响。收敛效度也得到了证实。结果表明重测信度近乎完美。
结论
问卷的首个乌克兰语版本与现有的原始英语版本等效。
