This study aimed to translate the Lymphedema Quality of Life Questionnaire-leg into Korean (K-LYMQOL-leg) and test its reliability and validity.
The LYMQOL-leg was translated forward and backward from English to Korean. Fifty-five patients with lower limb lymphedema completed the K-LYMQOL-leg and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30) at the first visit, and the K-LYMQOL-leg was re-administered within a week. Reliability was tested by calculating the intraclass correlation coefficient (ICC) and the Cronbach's alpha for each domain. Face validity was evaluated, and concurrent validity was verified by comparing the K-LYMQOL-leg domain scores with the corresponding EORTC-QLQ-C30 and limb volume scales. The known-group construct validity was then assessed.
Excellent reliability was confirmed by internal consistency (Cronbach's alpha coefficient, 0.851-0.878) and test-retest reliability (ICC, 0.901-0.936) in the four domains. A significant correlation was confirmed in the appearance domain with limb volume ( = 0.424) and in the other domains [function, symptom, and mood], with the EORTC-QLQ-C30 scales ( = -0.779, 0.712, and -0.783). Known-group validity was confirmed in all four domains.
The K-LYMQOL-leg verified in this study can be used in clinical practice to evaluate the Quality of Life (QOL) of patients with lymphedema or in research as an outcome.IMPLICATIONS FOR REHABILITATIONAmong cancer treatment-related complications, lymphedema of the lower extremities severely and persistently reduces the health-related quality of life of cancer survivors.The Korean version of the Lymphedema Quality of Life Questionnaire-leg (K-LYMQOL-leg) is an easy, reliable and valid questionnaire for patients with lower limb lymphedema.K-LYMQOL-leg will be useful in assessing the quality of life of patients with lower limb lymphedema in a clinical setting or for research purposes.
本研究旨在将淋巴水肿生活质量问卷-下肢（LYMQOL-leg）译为韩文（K-LYMQOL-leg）并检验其信度和效度。
将 LYMQOL-leg 从英文正向和反向译为韩文。55 例下肢淋巴水肿患者于首次就诊时同时完成 K-LYMQOL-leg 和欧洲癌症研究与治疗组织生活质量核心问卷 30 版（EORTC-QLQ-C30），并于一周内再次完成 K-LYMQOL-leg 评估。采用组内相关系数（ICC）和各领域 Cronbach's alpha 检验信度。通过与 EORTC-QLQ-C30 和肢体容积量表的比较，评价内容效度。然后评估已知群组的结构效度。
四个领域的内部一致性（Cronbach's alpha 系数，0.851-0.878）和重测信度（ICC，0.901-0.936）均证实具有极好的信度。在外观领域与肢体容积（ = 0.424）以及在功能、症状和情绪等其他领域与 EORTC-QLQ-C30 量表（ = -0.779、0.712 和-0.783）均存在显著相关性。在所有四个领域均证实具有已知群组的结构效度。
本研究中验证的 K-LYMQOL-leg 可用于临床实践中评估淋巴水肿患者的生活质量（QOL）或作为研究结局。
在癌症治疗相关并发症中，下肢淋巴水肿严重且持续地降低癌症幸存者的健康相关生活质量。下肢淋巴水肿生活质量问卷-韩文版（K-LYMQOL-leg）是一种评估下肢淋巴水肿患者简便、可靠且有效的问卷。K-LYMQOL-leg 将有助于在临床环境中评估下肢淋巴水肿患者的生活质量，或用于研究目的。
