Abstract

Objectives: To translate the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-ELD14 (EORTC QLQ-ELD14) into Chinese and validate its effectiveness in China.

Methods: The Chinese version was developed through a rigorous translation and back-translation process based on the Brislin model, followed by cross-cultural adaptation through expert consultation. A total of 260 elderly cancer patients from a tertiary hospital in Tianjin were recruited between June 2024 and February 2025 to evaluate the instrument's reliability and validity.

Results: Among the 248 completed responses, the Chinese version of the EORTC QLQ-ELD14 demonstrated robust psychometric properties. The questionnaire comprises 7 dimensions (14 items), with item-level content validity indices ranging from 0.800 to 1.000 and a scale-level content validity index of 0.980. Exploratory factor analysis identified 7 underlying factors, accounting for 82.913% of the cumulative variance. Internal consistency was excellent, with a Cronbach's α of 0.958 for the total scale and dimension alphas exceeding 0.800. Test-retest reliability was 0.849 for the total scale and ranged from 0.813 to 0.856 across dimension.

Significance of results: The Chinese version of the EORTC QLQ-ELD14 has good reliability and validity, which is suitable for evaluating the quality of life of elderly cancer patients within Chinese cultural contexts.

EORTC生活质量问卷- eld14中文版用于评估老年癌症患者生活质量的验证。

目的：将欧洲癌症研究与治疗组织生活质量问卷eld14 （EORTC QLQ-ELD14）翻译成中文并验证其在中国的有效性。方法：根据布里斯林模型，经过严格的翻译和反翻译过程，并通过专家咨询进行跨文化改编。本研究于2024年6月至2025年2月在天津市某三级医院招募260例老年肿瘤患者，对该量表进行信度和效度评估。结果：在248份已完成的问卷中，中文版的EORTC QLQ-ELD14表现出较强的心理测量特性。问卷包括7个维度（14个项目），项目层面的内容效度指数为0.800 ~ 1.000，量表层面的内容效度指数为0.980。探索性因子分析确定了7个潜在因素，占累积方差的82.913%。总体量表的Cronbach’s α为0.958，维度α大于0.800，内部一致性较好。总量表的重测信度为0.849，各维度的信度在0.813 ~ 0.856之间。结果的意义：中文版的EORTC QLQ-ELD14具有良好的信度和效度，适用于中国文化背景下老年癌症患者的生活质量评价。
