Background The Lymphoedema Quality-of-Life Questionnaire is a validated disease-specific instrument to measure the impact of lymphoedema on patients’ lives. In this study, we tested its psychometric properties and validated the use of the questionnaire in its Dutch translation. Methods We obtained the answers to a standardised questionnaire, including Lymphoedema Quality-of-Life Questionnaire and Short-Form (36) Health Survey, twice at an interval of 2 weeks in 60 patients with lower limb lymphoedema. Feasibility was tested on the basis of missing responses and response distribution. Structure was studied using factor analysis. The reliability of the Lymphoedema Quality-of-Life Questionnaire was assessed using Crohnbach’s α and test-retest reliability. Construct validity was tested by correlating Lymphoedema Quality-of-Life Questionnaire scores with the Short-Form (36) Health Survey scores. Results The response rate was 88.2%. One of the 22 items missed >10% of responses; another showed a borderline ceiling effect. Internal consistency was good and test-retest reliability was excellent. The Lymphoedema Quality-of-Life Questionnaire correlated well with the physical component of the Short-Form (36) Health Survey and moderately with the mental component, suggesting that its construct validity was good. Conclusion The Dutch Lymphoedema Quality-of-Life Questionnaire can be used for health-related quality-of-life research in lower limb lymphoedema patients.
