This study aimed to demonstrate the reliability and validity of the Korean version of the Lymphedema Quality of Life (LYMQOL) questionnaire. This study was a multicentered cross-sectional survey of patients with breast cancer-related lymphedema. The LYMQOL-arm questionnaire was translated from English to Korean. This 28-item instrument contains the overall quality of life (QOL) and is categorized into four domains: function, appearance, symptoms, and mood. In addition, the demographics and characteristics of lymphedema were assessed by reviewing the medical records. The LYMQOL-arm, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), and Breast Cancer Module 23 (EORTC QLQ-BR23) were administered. The internal consistency of the LYMQOL-arm was analyzed using Cronbach's , and test-retest reliability was examined using the intraclass correlation coefficient (ICC). Concurrent validity was evaluated using Pearson's correlation test between the LYMQOL-arm and the EORTC QLQ instruments. A total of 62 participants were enrolled in the study. All domains of the LYMQOL-arm showed high internal consistency, and the ICC of each domain and overall QOL ranged from 0.836 to 0.956 ( < 0.001). All domains and overall QOL scores of the LYMQOL-arm significantly correlated with most of the EORTC QLQ-C30 and EORTC QLQ-BR23 scales. Furthermore, it revealed a significant association with the degree of perceived edema. The Korean version of the LYMQOL-arm questionnaire has proven its reliability and validity in assessing QOL in patients with breast cancer-related lymphedema.
本研究旨在验证韩国版淋巴水肿生活质量问卷（LYMQOL）的可靠性和有效性。本研究为一项多中心横断面调查，对象为乳腺癌相关淋巴水肿患者。LYMQOL 臂问卷从英文翻译成韩文。该 28 项工具包含整体生活质量（QOL），并分为四个领域：功能、外观、症状和情绪。此外，通过查阅病历评估了淋巴水肿的人口统计学和特征。对 LYMQOL 臂、欧洲癌症研究与治疗组织生活质量问卷核心 30 项（EORTC QLQ-C30）和乳腺癌模块 23 项（EORTC QLQ-BR23）进行了评估。采用 Cronbach's 分析 LYMQOL 臂的内部一致性，采用 ICC 检验其重测信度。采用 Pearson 相关检验评估 LYMQOL 臂与 EORTC QLQ 仪器之间的同时效度。共有 62 名参与者纳入研究。LYMQOL 臂的所有领域均表现出较高的内部一致性，各领域和整体 QOL 的 ICC 范围为 0.836 至 0.956（ < 0.001）。LYMQOL 臂的所有领域和整体 QOL 评分与 EORTC QLQ-C30 和 EORTC QLQ-BR23 的大部分量表显著相关。此外，它与感知水肿程度显著相关。韩国版 LYMQOL 臂问卷在评估乳腺癌相关淋巴水肿患者的生活质量方面具有可靠性和有效性。
