Validation of the Brazilian version of the Gaudenz-Fragebogen : used in the differential diagnosis of female urinary incontinence

摘要

Objective: To validate the Brazilian version of the Gaudenz-Fragebogen questionnaire, used in the differential diagnosis of female stress and urge urinary incontinence. Methods: Reliability was validated through the application of test-retest in 60 women. For the evaluation of the concurrent validity criterion, the diagnoses-based on the questionnaire's adapted scores-were compared to the urodynamic study (gold standard) in 116 women with urinary incontinence. Results: The questionnaire was found to be reliable and showed stability. The sensitivity and specificity for the diagnosis of stress urinary incontinence were 9.0% and 96.7%, and for urge urinary incontinence, 44.7% and 70% respectively. Conclusion: The questionnaire is reliable and stable, and it is suitable to be included in the phases that precede the final diagnosis. However, its use is not recommended as a single resource to determine the differential diagnosis of female urinary incontinence.
