我们的研究评估了罗马尼亚SarQoL（R）问卷的心理测量特性。正态分布和高内部一致性发现。Sarcophytic主题报告降低全球生活质量相比，非sarcopenics。罗马尼亚版本的SarQoL（R）的问卷，概念上和字面上等同的源仪器，是合格的心理测量properties.Purpose/introduction方面，我们最近提供了一个翻译和文化定制的版本的第一个生活质量（QoL）的问卷，具体为肌肉减少症，SarQoL（R），在罗马尼亚语。本研究的目的是评估翻译的问卷的心理测量学性能。根据欧洲老年人肌肉减少症工作组（EWGSOP）提出的算法诊断肌肉减少症。为了检验心理测量学的表现，区分力，内部一致性，地板和天花板效应，结构效度分析。我们评估了SarQoL（R）和其他两个QoL questionnaire.Results saraprotic科目报告的全球生活质量降低非sarcopenic个人相比，类似/不同的领域之间的相关性。显着（p = 0.018）较高的总得分为非sarcoopenic科目相比，sarcoopenics表明一个良好的区分能力的罗马尼亚问卷。肌肉萎缩症患者在几乎所有领域的得分都显着降低。Cronbach α值为0.946，表明内部一致性较高。SF-36和EQ-5D问卷的相似领域得分与SarQoL（R）总分之间也存在强正相关。此外，较低的分数的生活质量已被证明是显着相关的较低的肌肉力量，在单变量分析，和较低的步态速度，无论是在单变量和多变量analysis.Conclusions我们的研究结果表明，罗马尼亚版本的SarQoL（R）问卷，合格的心理测量特性方面，可以是一个有用的工具，以评估体弱罗马尼亚人sarcopenia相关的生活质量。
Our study assessed the psychometric properties of the Romanian SarQoL (R) questionnaire. Normal distribution and high internal consistency were found. Sarcopenic subjects reported a reduced global quality of life compared to non-sarcopenics. The Romanian version of the SarQoL (R) questionnaire, conceptually and literally equivalent with the source instrument, is qualified in terms of psychometric properties.Purpose/introduction We have recently provided a translated and culturally tailored version of the first quality of life (QoL) questionnaire specific for sarcopenia, the SarQoL (R), in Romanian language. The aim of this study was to assess the psychometric performances of the translated questionnaire.Methods A total of 100 volunteers were enrolled in the study. Sarcopenia was diagnosed according to the algorithm proposed by the European Working Group on Sarcopenia in Older People (EWGSOP). To test the psychometric performance, discriminative power, internal consistency, floor and ceiling effects, and construct validity analyses were made. We assessed the correlation between SarQoL (R) and similar/different domains of other two QoL questionnaires.Results Sarcopenic subjects reported a reduced global QoL compared to non-sarcopenic individuals. Significantly (p = 0.018) higher total scores for non-sarcopenic subjects compared to those of sarcopenics indicate a good discriminative power of the Romanian questionnaire. Sarcopenic individuals had significantly lower scores in almost all domains. The Cronbach's alpha value of 0.946 indicates a high internal consistency. No floor or ceiling effects were found. A strong positive correlation was also found between similar domain scores from SF-36 and EQ-5D questionnaires with the Total SarQoL (R) score. Moreover, lower scores of quality of life have been shown to be significantly associated with lower muscle strength, in univariate analyses, and lower gait speed, both in univariate and multivariate analyses.Conclusions Our results indicate that the Romanian version of the SarQoL (R) questionnaire, qualified in terms of psychometric properties, could be a useful tool to assess the sarcopenia-related QoL among frail Romanian individuals.
