The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 15-Palliative Care (EORTC QLQ-C15-PAL) is a shortened version of the EORTC QLQ-C30, developed for use in advanced cancer patients.
We evaluated the psychometric properties of the Korean version of the EORTC QLQ-C15-PAL to determine if this tool can be used to evaluate Korean patients with cancer who receive palliative care.
A multicenter, cross-sectional survey was performed in palliative care units and hospices in Korea from September to October 2009. A total of 102 patients with cancer completed the questionnaires that included the EORTC QLQ-C15-PAL.
The compliance rate was high, with the missing rate for each item ranging from 0% to 7.8% (mean 3.1%). A multitrait scaling analysis revealed good convergent and discriminant validity, with only three scaling errors. The Cronbach's alpha coefficients ranged from 0.65 to 0.89. The questionnaire discriminated among patient subgroups with different clinical profiles (e.g., performance status and degree of oral intake), thereby demonstrating the clinical validity of this tool.
Our findings indicate that the Korean version of the EORTC QLQ-C15-PAL is a reliable and valid instrument with regard to its psychometric properties. This tool is suitable for measuring quality of life, particularly with regard to physical aspects, in Korean cancer patients who receive palliative care.
欧洲癌症研究与治疗组织生活质量问卷核心 15-姑息治疗版（EORTC QLQ-C15-PAL）是 EORTC QLQ-C30 的缩短版，专为晚期癌症患者使用而开发。
我们评估了 EORTC QLQ-C15-PAL 韩文版的心理测量特性，以确定该工具是否可用于评估接受姑息治疗的韩国癌症患者。
2009 年 9 月至 10 月，在韩国的姑息治疗病房和收容所进行了一项多中心、横断面调查。共有 102 名癌症患者完成了包括 EORTC QLQ-C15-PAL 在内的问卷。
问卷的完成率很高，每个项目的缺失率为 0%至 7.8%（平均 3.1%）。多特质评分分析显示具有良好的收敛和区分效度，只有 3 项评分错误。Cronbach's alpha 系数范围为 0.65 至 0.89。该问卷可区分具有不同临床特征的患者亚组（例如，表现状态和口腔摄入程度），从而证明了该工具的临床有效性。
我们的研究结果表明，EORTC QLQ-C15-PAL 韩文版在心理测量特性方面具有可靠性和有效性。该工具适合测量韩国姑息治疗癌症患者的生活质量，特别是在身体方面。
