Responsiveness of the Spanish Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaires Short Forms (PFDI-20 and PFIQ-7) in women with pelvic floor disorders.

OBJECTIVE

To evaluate the responsiveness of the Spanish versions of Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire Short Forms (PFDI-20 and PFIQ-7), in order to assess symptoms and quality of life in Spanish women with pelvic floor disorders.

STUDY DESIGN

Prospective observational study to assess the responsiveness in 85 women with pelvic floor disorders. PFDI-20 and PFIQ-7 were completed before and after Physiotherapy intervention. The responsiveness was assessed with the p values using the Wilcoxon signed-rank test, the standardized response means of the change (SRM) and the effect size (ES).

RESULTS

The Spanish PFDI-20 and PFIQ-7 and the subscales demonstrated small to good responsiveness. The responsiveness was higher for PFDI-20 than for PFIQ-7. The statistic for PFDI-20 was moderate to good (ES 0.68 and SRM 0.84; p<0.0001), and small to moderate for PFIQ-7 (ES 0.48 and SRM 0.57; p<0.0001). Regarding the subscales, the responsiveness was better for Pelvic Organ Prolapse Distress Inventory (POPDI) than Pelvic Organ Prolapse Impact Questionnaire (POPIQ) (ES 0.70 and SRM 0.78; ES 0.42 and SRM 0.47 respectively; p<0.0001). Moderate responsiveness was found for Urinary Distress Inventory (UDI) and Urinary Impact Questionnaire (UIQ) (ES 0.54 and SRM 0.67; ES 0.52 and SRM 0.61 respectively; p<0.0001). Colo-Rectal-Anal Distress Inventory (CRADI) and Colo-Rectal-Anal Impact Questionnaire (CRAIQ) showed poor responsiveness, small in both (ES 0.42, SRM 0.50 and p<0.0001; ES 0.34, SRM 0.39 respectively; p<0.001). All responsiveness was significant.

CONCLUSIONS

PFDI-20 and PFIQ-7 Spanish versions showed good responsiveness to evaluate the symptoms and the quality of life in Spanish women with PFD undergoing Physiotherapy treatment.
