A new questionnaire for urinary incontinence diagnosis in women: Development and testing

Objective: The purpose of this study was to develop a questionnaire for urinary incontinence diagnosis in women and to test its reliability and validity, with incontinence specialists' clinical evaluations as the gold standard. Study design: One hundred seventeen urogynecology outpatients with urinary incontinence symptoms completed the Questionnaire for Urinary Incontinence Diagnosis at enrollment and 1 week and 9 months later. Baseline clinical diagnoses were compared with Questionnaire for Urinary Incontinence Diagnosis diagnoses (criterion validity). Nine-month Questionnaire for Urinary Incontinence Diagnosis change scores were compared across treatment groups (responsiveness). Results: Clinical diagnoses included stress (n = 15), urge (n = 26), and mixed urinary incontinence (n = 72). Internal consistency and test-retest reliability estimates were good. Sensitivity and specificity were 85% (95% CI, 75%, 91%) and 71% (95% CI, 51% 87%), respectively, for stress urinary incontinence and 79% (95% CI, 69%, 86%) and 79% (95% CI, 54%, 94%), respectively, for urge urinary incontinence. The Questionnaire for Urinary Incontinence Diagnosis correctly diagnosed urinary incontinence type in 80% of subjects. Questionnaire for Urinary Incontinence Diagnosis Stress and Urge scores decreased significantly in treated subjects. Conclusion: The Questionnaire for Urinary Incontinence Diagnosis, a new 6-item questionnaire for female urinary incontinence type diagnosis is reliable and able to diagnose stress urinary incontinence and urge urinary incontinence in a referral urogynecology patient population with accuracy.
