The European Organization for Research and Treatment of Cancer (EORTC) QLQ-ELD14 is a validated tool that measures Health-related Quality-of-life (HRQOL) for elderly patients with cancer. This study was conducted to evaluate the psychometric properties of the Korean version of the EORTC QLQ-ELD14 to determine if this tool can be used to evaluate HRQOL for older Korean patients with cancer.
We recruited 439 elderly patients with cancer aged ≥60years from 11 cancer centers and completed the EORTC QLQ-ELD14 questionnaires. The reliability and validity of the EORTC QLQ-ELD14 questionnaire were assessed via Cronbach alpha, multitrait scaling analyses, correlation analyses with the EORTC QLQ-C30, and known-group comparisons. Known-group comparisons were conducted by dividing the patients into groups based on the cancer stage, depression level, and loss of mobility.
The scale structure of the Korean version of the EORTC QLQ-ELD14 was consistent with the originally hypothesized scale structure. Cronbach alpha coefficients ranged 0.65-0.88. Multitrait scaling analysis showed good item convergent and discriminant validity. Low scaling errors (3.1%) were observed. Divergent validity was demonstrated by no strong correlation with the EORTC QLQ C30. The clinical validity of the Korean version of the EORTC QLQ-ELD14 was demonstrated by its ability to discriminate among patient subgroups categorized by AJCC stage, depression level, and loss of mobility.
Our findings indicate that the Korean version of the EORTC QLQ-ELD14 questionnaire is reliable and valid for measuring QOL of older Korean patients with cancer.
欧洲癌症研究与治疗组织（EORTC）QLQ - ELD14是一种经过验证的工具，用于测量老年癌症患者的健康相关生活质量（HRQOL）。本研究旨在评估EORTC QLQ - ELD14韩语版的心理测量特性，以确定该工具是否可用于评估韩国老年癌症患者的HRQOL。
我们从11个癌症中心招募了439名年龄≥60岁的老年癌症患者，并完成了EORTC QLQ - ELD14问卷。通过克朗巴赫α系数、多特质量表分析、与EORTC QLQ - C30的相关性分析以及已知组比较，评估EORTC QLQ - ELD14问卷的信度和效度。已知组比较是根据癌症分期、抑郁水平和行动能力丧失将患者分组进行的。
EORTC QLQ - ELD14韩语版的量表结构与最初假设的量表结构一致。克朗巴赫α系数范围为0.65 - 0.88。多特质量表分析显示出良好的项目收敛效度和区分效度。观察到低量表误差（3.1%）。与EORTC QLQ C30无强相关性，证明了区分效度。EORTC QLQ - ELD14韩语版的临床效度通过其区分按美国癌症联合委员会（AJCC）分期、抑郁水平和行动能力丧失分类的患者亚组的能力得以证明。
我们的研究结果表明，EORTC QLQ - ELD14韩语版问卷对于测量韩国老年癌症患者的生活质量是可靠且有效的。
