We aimed to evaluate the reliability and validity of the adapted Korean version of the Quality-of-Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-26). Translation/retranslation of the English version of QUALEFFO was conducted, and all steps of the cross-cultural adaptation process were performed. The Korean version of the visual analog scale measure of pain, QUALEFFO-26 and the previously validated Short Form-36 (SF-36) were mailed to 162 consecutive patients with osteoporosis. Factor analysis and reliability assessment by kappa statistics of agreement for each item, the intraclass correlation coefficient and Cronbach's α were conducted. Construct validity was also evaluated by comparing the responses of QUALEFFO-26 with the responses of SF-36 using Pearson's correlation coefficient. Factor analysis extracted 3 factors. All items had a kappa statistics of agreement greater than 0.6. The QUALEFFO-26 showed good test/retest reliability (QUALEFFO-26: 0.8271). Internal consistency of Cronbach's α was found to be very good (QUALEFFO-26: 0.873). The Korean version of QUALEFFO-26 showed good significant correlation with SF-36 total score and with single SF-36 domains scores. The adapted Korean version of the QUALEFFO-26 was successfully translated and showed acceptable measurement properties and, as such, is considered suitable for outcome assessments in the Korean-speaking patients with osteoporosis.
我们旨在评估改编后的韩国版骨质疏松症欧洲基金会生活质量问卷（QUALEFFO - 26）的信度和效度。对QUALEFFO英文版进行了翻译/再翻译，并完成了跨文化适应过程的所有步骤。将韩国版疼痛视觉模拟量表、QUALEFFO - 26以及先前验证过的简短健康调查问卷36项版本（SF - 36）邮寄给162例连续性骨质疏松症患者。进行了因子分析以及通过kappa一致性统计对每个项目进行信度评估、组内相关系数和Cronbach's α分析。还通过使用Pearson相关系数比较QUALEFFO - 26与SF - 36的回答来评估结构效度。因子分析提取出3个因子。所有项目的kappa一致性统计均大于0.6。QUALEFFO - 26显示出良好的重测信度（QUALEFFO - 26：0.8271）。发现Cronbach's α的内部一致性非常好（QUALEFFO - 26：0.873）。韩国版QUALEFFO - 26与SF - 36总分及单个SF - 36领域得分显示出良好的显著相关性。改编后的韩国版QUALEFFO - 26成功完成翻译，显示出可接受的测量特性，因此被认为适用于韩国骨质疏松症患者的疗效评估。
