摘要
Purpose The purpose of this study was to translate and evaluate the psychometric properties of the Chinese version of the Upper Limb Lymphedema Quality of Life Questionnaire (C-ULLQoL).Methods Eighty-five participants completed the C-ULLQoL and the Functional Assessment of Cancer Therapy-Breast (C-FACT-B). The Cronbach’s alpha (α) was used to determine the internal consistency, and intraclass correlation coefficients (ICCs) – to evaluate the test-retest reliability. The content validity index (CVI) was assessed by a group of experts. Construct validity was examined by performing factor analysis and criterion validity by observing the correlations between C-ULLQoL with C-FACT-B.Results Cronbach’s α of the total scale was 0.930. ICC scores ranged from 0.874 to 0.938. The content validity of C-ULLQoL was acceptable. Two factors (65.488% of the variance) were extracted by exploratory factor analysis. A significant correlation was observed between C-ULLQoL and C-FACT-B (r = −0.611, p < 0.01).Conclusion The C-ULLQoL is a reliable and valid questionnaire that can be used in clinic and scientific practice for evaluating health-related quality of life in Chinese patients with breast cancer-related lymphedema.IMPLICATIONS FOR REHABILITATIONAn effective and comprehensive scale to measure the health-related quality of life (HRQoL) is essential because breast cancer-related lymphedema (BCRL) leads to various complications for patients, caregivers, and society.The Chinese version of the Upper Limb Lymphedema Quality of Life Scale (C-ULLQoL) is a valid, reliable, and practical instrument to comprehensively assess HRQoL in Chinese patients with BCRL.The C-ULLQoL can be used in both clinical and research settings to evaluate HRQoL of BCRL patients in China.
