Kolda lenfödem semptom şiddeti ve distres ölçeği’nin kültürel adaptasyonu, güvenirlik-geçerliği, lenfödem semptomları ve ödem değerlendirmeleri arasındaki ilişkinin incelenmesi

Abstract

This study was planned to adapt the Intensity Lymphedema Symptom Severity and Distress Survey-Arm (LSIDS-A) into Turkish, to investigate its reliability and validity, and to examine the relationship between the presence and severity of patient-reported symptoms and edema assessments in women undergoing breast cancer surgery. One hundred and twenty women (mean age = 52.6 years) who completed their breast cancer treatments were included in the study. The reliability of the Turkish version of the LSIDS-A was evaluated with internal consistency and test-retest analysis. Confirmatory factor analysis was performed to determine the construct validity. The criterion validity of the scale was evaluated by the Lymphedema Function, Disability and Health Scale - Upper Extremity (Lymph-ICF-UL), Upper Extremity Lymphedema Quality of Life Scale (ULL-27) and the shortened version of Disabilities of Arm, Shoulder and Hand Questionnaire (Quick-DASH). Concurrent validity was determined by the correlations between the total/subscale scores of Turkish LSIDS-A and the bioimpedance spectroscopy score (L-Dex). The internal consistency of the LSIDS-A-Tr was found to be strong/very strong (Cronbach's alpha= 0.87 - 0.91). The test-retest reliability for the total and subscale scores of the LSIDS-A-Tr was very strong (Intraclass correlation coefficient (ICC)= 0.91–0.95; p=0.001). The factor structure obtained from the data of Turkish LSIDS-A was found to be compatible with the factor structure of the original scale. A moderate or strong correlation was found between the total score of the LSIDS-A-Tr and the total scores of the Lymph-ICF-UL (r=0.84), ULL-27 (r=0.83) and Quick-DASH scales (r=0.74), (p=0.001). There was only a significant correlation between the LSIDS-A-soft tissue subscale score and the L-Dex score (r=0.46; p<0.01). There were positive and significant correlations between swelling, heaviness, tightness, and pain symptoms and objective edema evaluations (r=0.24-0.52, p<0.05). Compared to Stage 0 and Stage 1 patients, the presence and/or severity of all subjective symptoms was found to be higher in patients with Stage 2. The LSIDS-A-Tr is a valid and reliable scale for the evaluation of lymphedema symptoms. This scale can be used in clinical settings and research to comprehensively evaluate lymphedema symptoms. Finding significant relationships between subjective lymphedema symptoms and objective edema evaluations indicates that subjective symptoms should also be evaluated comprehensively in these patients in the clinical settings.
