title: Reliability and normal ranges for the Patient's Perception of Intensity of Urgency Scale in asymptomatic women.
abstract: METHODS
  Symptom prevalence (prospective cohort).
  
  
  METHODS
  1b.
  
  
  OBJECTIVE
  To measure the test-retest reliability of a 7-day bladder diary incorporating the Patient's Perception of Intensity of Urgency Scale (PPIUS), and to establish the normal values of the scale in a population of asymptomatic women.
  
  
  METHODS
  Women volunteers, aged > or =18 years, were screened with the International Consultation on Incontinence Modular Questionnaire - Female Lower Urinary Tract Symptoms Long Form, to exclude those with bothersome lower urinary tract symptoms. Participants completed two separate 7-day bladder diaries with a 1-week interval between. Reliability was assessed using intraclass correlation, Spearman's correlation, and Student's t-test.
  
  
  RESULTS
  Forty volunteers were recruited. Most (67.5%) reported no urgency episodes. Convenience voids accounted for 26.8% of all voids. There was a significant positive effect of age (r = 0.34, P = 0.034) on urgency episodes, but no effect on mean urge scores (r = -0.03, P = 0.843). The reliability of assessment of frequency (0.86), nocturia (0.84), and the mean urge scores (0.85), were better than the reliability of assessment of urgency episodes (0.56), which occurred infrequently. The 95th centile for daily urinary frequency was 7.27 and for weekly urgency episodes was 2.00.
  
  
  CONCLUSIONS
  The PPIUS is a reliable tool for assessing urinary urge sensation in women. Inclusion of this measure in bladder diaries does not compromise the recording of other variables.
