Female Pelvic Floor Dysfunction Chinese Version Questionnaire Development And Validation Chinese Population

Female pelvic floor disorders (PFD) is a group of diseases, including urinary incontinence (UI), fecal incontinence (FI) and pelvic organ prolapse (POP), which often combine with each other. Treatment for such diseases, in addition to anatomic reconstruction, the more important is to improve patient’s quality of life. Questionnaire as an assessment of patient-oriented approach is widely used in the PFD clinical treatment and research. Mmany questionnaires currently used in pelvic floor research were validated in population of middle class Americans in American English most of them were validated in the target languages. As the conditions of domestic clinicians, most of the clinical used questionnaires were self-translated, which lacks psychometric cross-language translation and validation. It impedes the domestic clinical use of questionnaires and needs to be resolved.ObjectiveIn this study, we introduced IIQ-7, PFIQ-7and another ICS recommended PISQ-12questionnaires. After developing the Chinese version of the above instruments,we aimed at validating them in the Chinese population. The Simplified Chinese version of SF-12was also developed, whose reliability was also verified in this study.Method1. According to the principles of psychometrics, the Chinese version of IIQ-7, PFIQ-7and PISQ-12were developed;2. The Simplified Chinese version of SF-12which has been validated in the Hongkong Chinese population was developed from the Traditional Hongkong Chinese;3. We validated the IIQ-7, PFIQ-7and PISQ-12in the Chinese population, and test the reliability of SF-12in the PFD patients.Result 74patients with urinary incontinence completed the IIQ-7Chinese version and SF-12questionnaires, after that the1h pad test was made;134incontinence/pelvic organ prolapse patients completed PFIQ-7and SF-12questionnaires;86respondents (45in the patients group and41in the control group) completed the PISQ-12and the SF-12questionnaires.All of the4questionnaires have high internal consistency (the Cronbach’s alpha of IIQ-7, PFIQ-7, PISQ-12and SF-12were0.824,0.801,0.725and0.881independently), high test-retest reliability (the ICC coefficients of IIQ-7, PFIQ-7, PISQ-12and SF-12were0.749,0.862,0.745and0.845), adequate split-half reliability (the half Cronbach’s alpha for IIQ-7, PFIQ-7, PISQ-12and SF-12were0.696/0.707,0.742/0.789,0.649/0.597and0.776/0.805). Of all the reliability test P <0.01; PFIQ-7and IIQ-7scores were negatively correlated with SF-12scores (P <0.01), IIQ-7scores were positively correlated with1h pad test (P<0.01), IIQ-7scores were positively correlated with the course of disease (P<0.05), PISQ-12scores and SF-12scores were positively correlated (P<0.01); factor analysis of IIQ-7, PFIQ-7and PISQ-12showed good construct validity.ConclusionThe Chinese version of IIQ-7, PFIQ-7and PISQ-12has high reliability and validity in the Chinese population (Mainland). They are highly recommended for clinical treatment and research. Of course, a good questionnaire should also have good responsiveness, which may be verified in future researches and clinical use.This study has filled the domestic (mainland) gap of psychometric translation and validation of PFD questionnaires. From now on, we have validated questionnaires for PFD research and clinical use.
