We translated and adapted transculturally the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) for Korean patients. The translated Korean version of QUALEFFO-41 showed satisfactory reliability and validity.
The aim of this study was to translate the QUALEFFO-41 for Korean patients and then validate the Korean version of QUALEFFO-41.
Translation and transcultural adaptation of the QUALEFFO-41 was conducted according to the international recommendations. Ninety-seven patients (mean age, 73.6 years) with osteoporosis were participated in validating the Korean version of QUALEFFO-41. To test reliability, internal consistency was evaluated using Cronbach's alpha coefficient. To test validity, convergent validity was assessed using correlation with the SF-12 and EQ-5D and discriminant validity was assessed using ROC curve analysis.
The English version of QUALEFFO-41 was translated and adapted to Korean without notable discrepancies. The Korean QUALEFFO-41 had good reliability with Cronbach's alpha ranging from 0.733 to 0.942. QUALEFFO-41 had good correlations to SF-12 and EQ-5D. Compared with subjects without history of vertebral fracture (VF), those with history of VF showed significantly worse scores according to QUALEFFO-41, but not according to SF-12 or EQ-5D. ROC curve analysis revealed that the physical function domain of QUALEFFO-41 had significant ability to discriminate between subjects with and without history of VF, while SF-12 or EQ-5D did not.
The Korean version of QUALEFFO-41 demonstrated relevant internal consistency, convergent validity, and discriminant validity, which can be recommended to evaluate quality of life in Koreans.
本研究旨在翻译 QUALEFFO-41 并验证 QUALEFFO-41 的韩文版本。
根据国际建议对 QUALEFFO-41 进行翻译和跨文化适应性调整。97 名骨质疏松症患者（平均年龄 73.6 岁）参与了 QUALEFFO-41 韩文版的验证。为了测试可靠性，使用 Cronbach's alpha 系数评估内部一致性。为了测试有效性，使用与 SF-12 和 EQ-5D 的相关性评估收敛有效性，使用 ROC 曲线分析评估判别有效性。
QUALEFFO-41 的英文版本被翻译成韩文，没有明显的差异。韩文 QUALEFFO-41 具有良好的可靠性，Cronbach's alpha 范围为 0.733 至 0.942。QUALEFFO-41 与 SF-12 和 EQ-5D 具有良好的相关性。与无椎体骨折（VF）病史的受试者相比，有 VF 病史的受试者根据 QUALEFFO-41 显示出明显较差的评分，但根据 SF-12 或 EQ-5D 则不然。ROC 曲线分析显示，QUALEFFO-41 的身体功能域具有区分有和无 VF 病史受试者的显著能力，而 SF-12 或 EQ-5D 则没有。
QUALEFFO-41 的韩文版本表现出相关的内部一致性、收敛有效性和判别有效性，可用于评估韩国人的生活质量。
