最近，SarQoL((R)) (Sarcopenia and Quality of Life)，一种针对肌肉减少症的生活质量（QoL）问卷被成功开发出来。出于实际原因，在其他人群中验证该问卷很有意义。本横断面研究的目的是将SarQoL（(R)）翻译和调整为波兰语，并标准化该方法在波兰评估肌肉减少症个体的心理测量特性的有效性。翻译过程中使用的是英文版本。研究对象为106名居住在社区的白种人，年龄为73.3±5.94岁（65.1%为女性），其中60人被诊断为肌肉减少症。翻译和跨文化适应按照具体的标准准则分五个阶段进行。在翻译过程中没有出现重大的语言问题。数据证实了良好的判别效度，即所有领域的得分均显著降低（肌少症患者的总体生活质量比非肌少症患者降低；54.9 +/- 16.5比63.3 +/- 17.1,p = 0.013），内部一致性高（Cronbach's alpha系数为0.92）。SarQoL（(R)）得分与其他维度相似的问卷（SF-36v2(R)健康调查和euroqol -5维度）得分显著相关，表明SarQoL((R))-PL问卷具有一致的结构效度。没有发现地板/天花板效应。检验结果与复验结果非常吻合（类内相关系数：0.99）。第一个波兰语版本的SarQoL（(R)）问卷是有效和一致的，因此可以可靠地用于临床和研究目的，关于肌少症患者的生活质量评估。然而，需要进一步的研究，特别是前瞻性研究，以确定波兰方案和特异性的潜在局限性和新工具的适用性。
Recently, SarQoL((R)) (Sarcopenia and Quality of Life), a quality of life (QoL) questionnaire specific to sarcopenia, was successfully developed. For practical reasons, there is a great interest in validating this questionnaire in other populations. The aim of this cross-sectional study was to translate and adjust the SarQoL((R)) into Polish and to standardize the validity of this method for the assessment of sarcopenic individuals in Poland with regard to psychometric properties. The English version was used for the translation process. A total of 106 community-dwelling Caucasian subjects aged 73.3 +/- 5.94 years (65.1% females) were studied, with 60 participants being diagnosed sarcopenic. The translation and cross-cultural adaptation was carried out in five phases according to specific standard guidelines. There were no major linguistic issues in the translation process. The data confirmed a good discriminant validity, i.e., significantly lower scores for all domains (reduced global QoL in sarcopenic subjects compared to non-sarcopenic ones; 54.9 +/- 16.5 vs. 63.3 +/- 17.1, p = 0.013), and high internal consistency (Cronbach's alpha coefficient was 0.92). The significant correlation of the SarQoL((R)) scores with those of other questionnaires (SF-36v2((R)) Health Survey and EuroQoL-5-Dimension) that are supposed to have similar dimensions indicated the consistent construct validity of the SarQoL((R))-PL questionnaire. No floor/ceiling effects were found. An excellent agreement was found between the test and the re-test (intraclass coefficient correlation (ICC): 0.99). The first Polish version of the SarQoL((R)) questionnaire is valid and consistent and therefore may be used with reliability for clinical and research purposes regarding QoL assessment of sarcopenic individuals. However, further research, in particular prospective studies, is needed to determine potential limitations and the suitability of the new tool for the Polish scenario and specificity.
