The Sarcopenia Quality of Life (SarQoL) questionnaire has been translated into various languages. This study validated the Taiwanese version of the SarQoL (SarQoL-TW) questionnaire.
Forward-backward translation was conducted, along with a test of the prefinal version of the translated questionnaire. To validate the psychometric properties of the questionnaire, 50 older adults with sarcopenia and 50 older adults without sarcopenia completed the SarQoL-TW, the Short Form12 Health Survey (SF-12), and the EQ-5D-3L questionnaire. Participants with sarcopenia were asked to complete the SarQoL-TW questionnaire once more after 2 weeks. Validating the psychometric properties of the SarQoL-TW questionnaire involved assessing its discriminative power, internal consistency, construct validity, test-retest reliability, and potential floor and ceiling effects.
The SarQoL-TW questionnaire was translated without major difficulties. The psychometric analysis revealed that older adults with sarcopenia scored significantly lower on the SarQoL-TW, both overall and in some of the domains. The Cronbach's alpha of 0.846 indicated high internal consistency. The SarQoL-TW questionnaire correlated well with similar constructs on the SF-12 and EQ-5D-3L for convergent validity and correlated weakly with distinct domains for divergent validity, confirming its favorable construct validity. The test-retest reliability was excellent (intraclass correlation coefficient: 0.970). Neither floor nor ceiling effects were observed.
The SarQoL-TW questionnaire is a reliable and valid questionnaire, useful for assessing quality of life in older adults with sarcopenia in clinical practice and research.
肌少症生活质量（SarQoL）问卷已被翻译成多种语言。本研究对SarQoL问卷的台湾版本（SarQoL-TW）进行了验证。
进行了前后向翻译，并对翻译问卷的预终版进行了测试。为了验证问卷的心理测量特性，50名患有肌少症的老年人和50名未患有肌少症的老年人完成了SarQoL-TW、简短健康调查问卷12（SF-12）和EQ-5D-3L问卷。患有肌少症的参与者在2周后再次被要求完成SarQoL-TW问卷。验证SarQoL-TW问卷的心理测量特性包括评估其区分能力、内部一致性、结构效度、重测信度以及潜在的地板效应和天花板效应。
SarQoL-TW问卷的翻译没有遇到重大困难。心理测量分析显示，患有肌少症的老年人在SarQoL-TW上的总体得分以及在某些领域的得分显著较低。Cronbach's α系数为0.846，表明内部一致性较高。SarQoL-TW问卷与SF-12和EQ-5D-3L上的类似结构在收敛效度方面相关性良好，与不同领域在区分效度方面相关性较弱，证实了其良好的结构效度。重测信度极佳（组内相关系数：0.970）。未观察到地板效应和天花板效应。
SarQoL-TW问卷是一份可靠且有效的问卷，有助于在临床实践和研究中评估患有肌少症的老年人的生活质量。
