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.
