Abstract

Objective: This study aimed to adapt the Questionnaire for Urinary Incontinence Diagnosis (QUID) into Brazilian Portuguese (QUID-Br) and evaluate its measurement properties, given as reliability, validity, and responsiveness in women with urinary incontinence. Study design: It was a methodological study which enrolled 168 women (mean age = 55.1, standard deviation = 17.9 years old). Translation and cross-cultural adaptation were done and subsequently analysis of the measurement properties of QUID-Br were tested: structural validity (by exploratory and confirmatory factory analysis) internal consistency (Cronbach's a) construct validity (Pearson Correlation), and test-retest reliability (Intraclass Correlation Coefficient). Results: The QUID-Br two-factor was confirmed showing two domains with three items each: stress urinary incontinence (SUI) and urge urinary incontinence (UUI). Furthermore, QUID-Br showed acceptable internal consistency for both scales (Cronbach's a> 0.70), reliability {[}intraclass correlation coefficient (ICC = 0.85 for SUI and 0.87 for UUI)] with 95 % confidence interval (CI) and construct validity - with all the hypothesis raised a priori being confirmed. Conclusions: The results of the present investigation showed that the QUID-Br is a valid, reliable, and consistent instrument to be administered to Brazilian women and its use is recommended in clinical practice and research.
