Background: Effective management of lower extremity lymphedema requires its recognition as a distinct clinical entity. This study aimed to evaluate the validity and reliability of the Turkish version of the Lymphedema Symptom Intensity and Distress Survey–Lower Limb (LSIDS-L), a tool designed to assess both the severity and distress of symptoms in patients with lower limb lymphedema. Aims: To evaluate the validity and reliability of the Turkish version of the Lymphedema Symptom Intensity and Distress Survey–Lower Limb (LSIDS-L) in patients with lower extremity lymphedema. Study design: Diagnostic Accuracy Study. Methods: The LSIDS-L was translated and culturally adapted into Turkish using the forward-backward translation method. The final version was administered to 155 patients alongside the Lymphoedema Quality of Life Questionnaire–Leg (LYMQOL-Leg). Reliability was assessed using a 7-days test-retest approach. Descriptive statistics were used for demographic data. Construct validity was evaluated using Spearman’s rank correlation coefficient, while internal consistency and test-retest reliability were assessed via Cronbach’s alpha and the intraclass correlation coefficient (ICC), respectively. Results: The questionnaire demonstrated excellent test-retest reliability with ICC1k = 0.9989 and r = 0.9970. Internal consistency was also high, with a Cronbach’s alpha of 0.9180 and a standardized alpha of 0.9145, indicating strong coherence among items. Conclusion: The Turkish version of the LSIDS-L (LSIDS-L-TR) is a valid and reliable instrument for assessing symptom intensity and distress in patients with lower extremity lymphedema. It offers a comprehensive tool for use in both clinical practice and research settings.
