title: Validation of the modified American Urological Association symptom score.
abstract: OBJECTIVE
  We created a shorter version of the American Urological Association symptom score, called UWIN (urgency, weak stream, incomplete emptying and nocturia).
  
  
  METHODS
  Participants in Prostate Cancer Awareness Week from 2006 and 2007 were administered the regular American Urological Association symptom score and UWIN. A total of 278 participants completed each questionnaire. Total scores of each participant for the American Urological Association symptom score (range 0 to 35) and UWIN (range 0 to 12) were evaluated using Spearman's correlation coefficients and Bland-Altman plots to determine the level of agreement between the 2 questionnaires.
  
  
  RESULTS
  The correlation between the total American Urological Association symptom score (range 0 to 35) and the total UWIN score (range 0 to 12) was 0.913 (p<0.0001). The correlation between the quality of life question on the American Urological Association symptom score and UWIN was 0.821 using the Spearman correlation coefficient (p<0.0001). A second analysis performed using Bland-Altman plots showed good agreement between the American Urological Association symptom score and UWIN. Overall, respondents tended to have slightly higher UWIN total scores than their American Urological Association symptom scores.
  
  
  CONCLUSIONS
  This study validates that the UWIN questionnaire can be used in place of the American Urological Association symptom score. The UWIN questionnaire will lessen the burden on the respondent, broaden the applicability of the instrument and make collecting data as efficient and effective as possible.
