The Reliability and Validity of the Turkish Version of the Lipedema Screening Questionnaire

Abstract Background/ Aim: The aim of this study was to investigate the reliability and validity of the Turkish version of the Lipedema Screening Questionnaire (T-LSQ). Method: The study involved 59 female volunteers diagnosed with lipedema by a cardiovascular surgeon. Key demographics such as age, onset age, lipedema types and stages, clinical features, and BMI were recorded. The Turkish adaptation of the LSQ was performed in accordance with the protocol of Beaton. Confirmatory factor analysis was performed for structural validity. For concurrent validity, T- LSQ, the Lower Extremity Functional Scale (LEFS), the Lymphedema Life Impact Scale (LLIS), and the Lymphoedema Functioning, Disability and Health Quastionnaire for Lower Extremity Lymphedema (Lymph-ICF-LL) were applied and the correlation between the scale responses was analyzed. Test-retest and internal consistency reliability were performed.
