Translation and Validation of Bristol Female Lower Urinary Tract Symptoms Questionnaire for Urinary Incontinence in Urdu

Background In this study, we aimed to translate and validate the 19-item version of the Bristol Female Lower Urinary Tract Symptoms (Bristol FLUTS) Questionnaire in Urdu among women experiencing urinary incontinence at a tertiary care hospital in Karachi, Pakistan. Methodology A cross-sectional validation study was conducted in the urology clinic at Aga Khan University Hospital, Karachi, Pakistan, between April and September 2021. After forward and backward translation of the Bristol FLUTS questionnaire, content validation was done by six experts, followed by the administration of the questionnaire to 10 respondents in the pilot phase of the study. In total, 207 participants were approached to fill the final version of the translated questionnaire. Overall, 188 respondents filled out the questionnaire, including 94 women with urinary incontinence and 94 women from the community to test construct validity. Finally, 30 women with urinary incontinence were asked to fill the form again two weeks later to determine test-retest reliability. Cronbach’s alpha was employed to assess the internal consistency of the questionnaire. Results The questionnaire displayed good content validity for reliability (content validity index: 0.84) and clarity (0.89). The scores reported by cases were significantly higher than the controls in all but the sexual function domain, suggesting good construct validity. Cronbach’s alpha of 0.81 signified good internal consistency, and a Pearson’s coefficient of 0.993 (p < 0.001) comparing responses at baseline and after two weeks indicated good test-retest reliability. Conclusions The Urdu translation of the Bristol FLUTS is a valid and reliable questionnaire that can be used in the clinical setting.
