title: [Exploratory and confirmatory factor analyses for testing validity and reliability of the Chinese language questionnaire for urinary incontinence diagnosis].
abstract: OBJECTIVE
  To translate questionnaire for urinary incontinence diagnosis (QUID) into Chinese and to test its reliability and validity.
  
  
  METHODS
  The English version of QUID was translated into Chinese. The clinaical data of 95 patinents with urinary incontinence who were test by urinary dynamic study in Peking Union Medical College Hospital from May 2014 to May 2015 were analyzed prospectively. The reliability of QUID was evaluated by completing QUID twice. The validity of QUID was evaluated by the standard of urinary dynamic study.
  
  
  RESULTS
  Internal consistency (Cronbach α) of the items that pertained to stress urinary incontinence (SUI) and to urge urinary incontinence (UUI) were 0.91 and 0.89, respectively. Test-retest reliability (Kappa) was 0.795 and criterion validity (Kappa) was 0.62. Sensitivity and specificity were 83% (43/52) and 86% (37/43), respectively, for SUI, and 72% (13/18) and 86% (66/77), respectively, for UUI.
  
  
  CONCLUSIONS
  QUID has good reliability and validity. It could be used in Chinese urinary incontinence women.
