Turkish Validity and Reliability of PRAFAB Questionnaire: A Validation Study

Abstract

Aim: PRAFAB-Questionnaire is a short, responsive, and practical tool that assesses subjective severity and the impact of urinary incontinence (UI). The aim of this study was to conduct a Turkish adaptation, validity and reliability of the PRAFAB-Questionnaire. Methods: A total of 55 women with stress and mixed UI complaints were included in the study. The English version of the questionnaire was translated into Turkish. Explanatory and confirmatory factor analysis, concurrent validity (with Incontinence Severity Index (ISI) and Visual Analogue Scale (VAS) for body/selfimage) and face validity were conducted for validity. Women were asked to refill the questionnaire after one week. Test-retest results and Cronbach's alpha coefficient were calculated for reliability analysis. Results: Explanatory factor analysis revealed that the questionnaire had only one factor, and confirmatory factor analysis confirmed this single factor. There was a moderate positive correlation between PRAFAB-Questionnaire and VAS scores (r = 0.690, p < .001). There was a strong positive correlation between PRAFAB-Questionnaire and ISI (r = 0.741, p < .001). PRAFAB also had face validity. Reliability between PRAFAB-Questionnaire items and total score was good to excellent (ICC: 0.807-0.925). Cronbach's alpha coefficient was 0.720. Conclusion: Turkish version of PRAFAB-Questionnaire has been shown valid and reliable. The responsiveness of the questionnaire needs to be evaluated for different types of UI for further studies.
