OBJECTIVES To develop and validate a standardized tool assessing urinary symptoms among men and women
with stress, urge, frequency, or urinary obstructive symptoms for use in clinical practice to
complement clinical measures and diagnosis.
METHODS After development by an advisory committee and comprehension testing with patients, the Urinary
Symptoms Profile (USP) item content and validity were evaluated by clinicians. Patients with urinary
symptoms (n ⫽ 253) and without symptoms (n ⫽ 75) completed the final questionnaire at day 0 and
day 7. Psychometric properties were assessed, including construct and clinical validity, reliability, and
predictive ability for detection of and differentiation between urinary disorders.
RESULTS Principal Component Analysis with Varimax Rotation confirmed the final USP structure of 13
items in 3 dimensions: stress urinary incontinence (SUI), overactive bladder (OAB), and low
stream (LS). Internal consistency reliability (Cronbach’s alpha ranging from 0.69 to 0.94) and
concurrent validity (Spearman correlation coefficients between International Consultation on
Incontinence Questionnaire and SUI and OAB dimensions of 0.73 and 0.62, respectively) were
good. Test-retest reproducibility over 7 days was excellent in stable patients (Intraclass Corre-
lation Coefficients from 0.84 to 0.91). USP clinical validity was demonstrated by comparing
micturition diary with USP scores. USP dimension scores were excellent predictors of urinary
disorder presence and identification.
CONCLUSIONS USP is the first valid and reliable questionnaire providing comprehensive evaluation of all
urinary disorders and their severity in both men and women with SUI, OAB, and LS. It allows
the screening and contributes to the differential diagnosis of these symptoms. The USP is a
valuable tool for use in clinical practice. UROLOGY 71: 646 – 656, 2008. © 2008 Elsevier Inc.
