The Turkish Language and Psychometric Validation of the Bladder Control Self-assessment Questionnaire Evaluating the Lower Urinary Tract Dysfunction

Abstract

Objective: The aim of this study was to develop and validate the Turkish version of the Bladder Control Self-assessment Questionnaire (B-SAQ). Materials and Methods: B-SAQ that comprises two parts and four questions in each section was translated into Turkish, followed by a back-translation into English. The study included 79 and 49 women who were admitted to the urology outpatient clinic with and without complaints of lower urinary tract symptom (LUTS), respectively. Turkish B-SAQ questionnaire was filled for the second time by 67 patients after a two week interval for test-retest correlation. All patients filled the Turkish B-SAQ form, International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) and Overactive Bladder Screener (OAB-V8) questionnaire. Results: The Cronbach alpha value for B-SAQ was 0.868. Reliability of the test/retest was found to be 0.860 (p<0.001). There were statistically significant differences in B-SAQ scores between the controls and patients (p<0.001). Convergent validity analyzes with ICIQ-SF and OAB-V8 (respectively r=0.61 and r=0.44, p<0.001). The total B-SAQ cut-off score was determined as 7. The sensitivity and specificity of B-SAQ were 96% in women with LUTS. Conclusion: Turkish version of B-SAQ is a valid and reliable questionnaire to evaluate the symptoms and disorders of patients with LUTS.
