Abstract

Introduction and hypothesis: The purpose of this study was to investigate the reliability and validity of the Chinese version of Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ).

Methods: Women who presented for pelvic floor disorders completed the Chinese version of PFDI and PFIQ, SF-36, a 3-day urinary and fecal diary. POP-Q assessment, urodynamic study, anal manometry, and ultrasound were performed where appropriate.

Results: Five hundred and ninety-seven women completed the study. The Cronbach's alpha and test-retest reliability of PFDI and PFIQ was 0.92 and 0.98, and 0.77 and 0.79, respectively. Convergent validity was demonstrated with negative correlation of PFDI and PFIQ with SF-36; positive correlation of staging of prolapse, urinary or fecal incontinent episodes with the respective subscales of PFDI and PFIQ.

Conclusions: The Chinese version of PFDI and PFIQ are reliable and valid condition-specific health-related quality of life questionnaires for women with pelvic floor disorders.
