We aimed to evaluate the reliability and validity of the adapted Korean version of the Italian Spine Youth Quality of Life (ISYQOL) questionnaire. Translation/retranslation of the English version of ISYQOL was conducted, and all steps of the cross-cultural adaptation process were performed. The Korean version of the ISYQOL and the previously validated Scoliosis Research Society-22 (SRS-22) questionnaire were mailed to 120 consecutive idiopathic scoliosis patients wearing brace. Factor analysis and reliability assessment by kappa statistics of agreement for each item, the intraclass correlation coefficient (ICC) and Cronbach’s α were conducted. Construct validity was also evaluated by comparing the responses of ISYQOL with the responses of SRS-22 by using Pearson’s correlation coefficient. Factor analysis extracted 2 factors. All items had a kappa statistics of agreement greater than 0.6. The ISYQOL showed good test/re-test reliability (ICC = 0.812). Internal consistency of Cronbach’s α was found to be very good (α = 0.873). The Korean version of ISYQOL showed good significant correlation with SRS-22 total score and with single SRS-22 domains scores. The adapted Korean version of the ISYQOL was successfully translated and showed acceptable measurement properties, and as such, is considered suitable for outcome assessments in the Korean speaking patients with idiopathic scoliosis.

我们旨在评估韩国版意大利脊柱青年生活质量 (ISYQOL) 问卷的信度和效度。进行了 ISYQOL 英文版的翻译/重新翻译，并执行了跨文化适应过程的所有步骤。韩国版的 ISYQOL 和先前经过验证的脊柱侧弯研究协会 22 (SRS-22) 问卷被邮寄给 120 名连续佩戴支具的特发性脊柱侧弯患者。对每个项目的一致性kappa统计、组内相关系数(ICC)和Cronbach's α进行因子分析和可靠性评估。还通过使用 Pearson 相关系数比较 ISYQOL 的反应与 SRS-22 的反应来评估结构有效性。因子分析提取2个因子。所有项目的一致性 kappa 统计数据均大于 0.6。ISYQOL 显示出良好的测试/重新测试可靠性（ICC = 0.812）。发现 Cronbach α 的内部一致性非常好（α = 0.873）。韩文版 ISYQOL 与 SRS-22 总分和单个 SRS-22 域得分显示出良好的显着相关性。ISYQOL 的改编韩文版本被成功翻译并显示出可接受的测量特性，因此，被认为适用于韩语特发性脊柱侧弯患者的结果评估。韩文版 ISYQOL 与 SRS-22 总分和单个 SRS-22 域得分显示出良好的显着相关性。ISYQOL 的改编韩文版本被成功翻译并显示出可接受的测量特性，因此，被认为适用于韩语特发性脊柱侧弯患者的结果评估。韩文版 ISYQOL 与 SRS-22 总分和单个 SRS-22 域得分显示出良好的显着相关性。ISYQOL 的改编韩文版本被成功翻译并显示出可接受的测量特性，因此，被认为适用于韩语特发性脊柱侧弯患者的结果评估。
