INTRODUCTION AND HYPOTHESIS: The differential diagnosis of urinary symptoms may allow health professionals to establish a therapeutic objective and to choose the appropriate treatment for the patient's complaint. The aim of this study was to cross-culturally adapt the Three Incontinence Questionnaire (3IQ) into Brazilian Portuguese (3IQ-Br) and to analyze test-retest reliability, construct, and criterion validity in women.
METHODS: The cross-cultural adaptation of the 3IQ-Br included forward-translation, back-translation, and consensus among an expert committee. Participants with and without urinary incontinence (UI) completed the 3IQ-Br, King's Health Questionnaire (KHQ), and Questionnaire for Female Urinary Incontinence Diagnosis (QUID-Br). Only women with UI answered 3IQ-Br after 7-10 days. Test-retest reliability and construct validity were analyzed using the Cohen linear kappa (k). The 3IQ-Br accuracy was analyzed using the area under the curve (AUC) of the receiver-operating characteristic (ROC) curve, considering the sensitivity and specificity to correctly classify women with and without UI.
RESULTS: The reliability of each question from the 3IQ-Br was considered substantial in the test-retest. The agreement among 3IQ-Br, QUID-Br, and KHQ was almost perfect for UI diagnosis (k > 0.8). The 3IQ-Br was considered to have good accuracy in distinguishing women with UI considering the KHQ (AUC 0.83, 95% confidence interval [CI] 0.78 to 0.87, p < 0.001), and fair to the QUID-Br (AUC 0.73, 95% CI 0.68 to 0.78; p < 0.001).
CONCLUSIONS: The results of this study showed that this version of the 3IQ-Br has acceptable measurement properties for identifying and differentiating UI symptoms in Brazilian women.
