“…The internal consistency was acceptable to excellent in the arm version and good to excellent in the leg version. These accord with the results in the other studies of the arm and leg versions [9][10][11][12][13].…”

“…Based on practical issues and statistical considerations they found it important to keep the size of the LYMQOL small to make it acceptable for users. None of the other translated versions of the LYMQOL have conducted a face validity evaluation of the questionnaire [7,[9][10][11][12][13].…”

“…For obvious reasons such a construction would probably facilitate a positive and significant correlation. However, the Turkish studies [10][11][12][13] also used other QoL instruments to analyse the construct validity and found good to very good correlations with the LYMQOL in these.…”

“…Consequently the LYMQOL can be seen as a better condition-specific instrument as the severity of the lymphoedema has impact on the QoL. No evaluations have been carried out in the previous publications of validation of the LYMQOL concerning the association between objective or subjective measures of lymphoedema volume and QoL aspects [9][10][11][12][13].…”

“…The LYMQOL is a self-report questionnaire with two versions; one adapted for oedema of the arms with 28 questions and one for oedema of the legs with 27 questions. The LYMQOL leg version has been translated into Dutch and validated [9] and the arm and leg versions have been translated into Turkish and validated by two research groups [10][11][12][13].…”

Background: The aim of this study was to validate a translated Swedish version of the lymphoedemaspecific quality of life questionnaire (LYMQOL) in a cohort of Swedish cancer patients with secondary lymphoedema of the limbs after cancer treatment. Material and methods: We recruited 102 patients with lymphoedema of the arms or legs after cancer treatment who were visiting lymphoedema therapists at the departments of oncology at the university hospitals in Link€ oping and Umeå. The LYMQOL questionnaires were translated forward and backward from English to Swedish. Content and face validity were evaluated. The construct validity was assessed by comparing the LYMQOL with the Short Form Health Survey (SF-36) and the perceived degree of lymphoedema of the limbs, respectively. Reliability was determined through test-retest. The internal consistency was assessed by determining Cronbach's alpha and by factor analysis. Results: The content and face validity assessments showed that LYMQOL was an easy, clear and not too long questionnaire to use for patients with lymphoedema. Construct validity was high in both versions when compared with the SF-36. The association between the degrees of perceived lymphoedema and the LYMQOL was only significant in the domains Function and Body Image in the arm version, whereas all domains in the leg version were significant. The reliability was good for the arm version (intra-class-correlation coefficients 0.53-0.87) and very good for the leg version (intra-class-correlation coefficients 0.78-0.90). The internal consistency was acceptable to excellent, with Cronbach's alpha values between 0.79-0.93 (arm-version) and 0.87-0.94 (leg-version). The factor analysis confirmed the usefulness of the four domains in the LYMQOL versions. Conclusions: This study confirmed the validity of the Swedish version of LYMQOL and demonstrated that LYMQOL may be a simple and useful tool for use in clinical practice and scientific contexts for evaluating QoL in patients with lymphoedema of the limbs.
