title: [Validation of incontinence impact questionnaire short form in Chinese population].
abstract: OBJECTIVE
  To study reliability and validity of incontinence impact questionnaire short form (IIQ-7) in the Chinese population.
  
  
  METHODS
  IIQ-7 form was translated into Chinese; 74 patients with urinary incontinence completed the IIQ-7 simplified Chinese version and short-form 12-item health survey (SF-12) questionnaires. The urinary incontinence patient also ran a 1 hour pad test. Then, reliability and validity of those forms were analyzed.
  
  
  RESULTS
  The Cronbach's alpha of IIQ-7 simplified Chinese version was 0.824 (P<0.01). The intra-class correlation coefficient of IIQ-7 simplified Chinese version was 0.749 (P<0.01). IIQ-7 simplified Chinese version scores were negatively correlated with SF-12 scores (Spearman correlation coefficient: -0.570, P<0.01), IIQ-7 simplified Chinese version scores were positively correlated with 1 hour pad test (Spearman correlation coefficient: 0.461, P<0.01), IIQ-7 simplified Chinese version scores were also positively correlated with the course of disease (Spearman correlation coefficient: 0.235, P<0.05). Factor analysis of IIQ-7 simplified Chinese version showed good construct validity.
  
  
  CONCLUSIONS
  The simplified Chinese version of IIQ-7 has higher reliability and validity in the Chinese population. They are highly recommended for clinical treatment and research.
