Reliability and validity of the Turkish language version of the Core Lower Urinary Tract Symptom Score
(John Wiley and Sons Inc, 2022) Erbay,M.E.; Tarhan,S.T.
Objectives: The purpose of this study was to develop the Turkish version of the Core Lower Urinary Tract Symptom Score (CLSS) and determine its psychometric properties in Turkish subjects. Methods: A total of 428 subjects, 259 with lower urinary tract symptoms (LUTS) and 169 without any complaints, were included in the study. In addition, 40 subjects were included in the study for test-retest analysis. After the Turkish version of the CLSS was created, all patients underwent medical history, physical examination, complete urinalysis, urinary ultrasonography, and filled out a CLSS. In addition, men were asked to fill in International Prostate Symptom Score (IPSS), International Consultation on Incontinence Questionnaire-Male LUTS and National Institutes of Health Chronic Prostatitis Symptom Index. Women completed the Bristol Female LUTS-Short Form and IPSS. The patients from the test-retest group were asked to fill out the CLSS two times at 2-week intervals. Results: CLSS showed high internal consistency (Cronbach's α for men and women was 0.909 and 0.767, respectively). The test-retest reliability of CLSS was high for subdomains (intraclass correlation coefficient was 0.739-0.962). Scores of CLSS were significantly higher in the study group than the control group (P < 0.001). In men and women, it showed very strong convergent validity (P < 0.0001) with subdomain related to other questionnaires. In our confirmatory factor analysis, the original model of CLSS was found to be compatible. Conclusions: The Turkish version of CLSS is a valid and reliable questionnaire to evaluate the symptoms and disorders of patients with LUTS. © 2022 John Wiley & Sons Australia, Ltd.
