Swedish validation of the Pelvic Floor Questionnaire for pregnant and postpartum women

Abstract

Introduction and hypothesis The German “Pelvic Floor Questionnaire for pregnant and postpartum women” is a self-administered questionnaire customized for pregnancy and the postpartum period that assesses four domains of pelvic floor function regarding perceived symptoms, suffering, and impact on quality of life: bladder, bowel, prolapse, and sexual function. No similar questionnaire is available in Swedish, despite a high prevalence of pregnancy and postpartum pelvic floor dysfunction. Thus, we aimed to translate the validated German questionnaire into Swedish and test its validity and reliability in a Swedish population. Methods Translation and cultural adaptation were performed according to guidelines. Of the 248 women who answered the Swedish questionnaire, 57 filled out the questionnaire twice to evaluate test-retest reliability. We also assessed internal consistency and discriminant validity. Results The Swedish version of the questionnaire showed good face and content validity. Cronbach’s alpha was in the acceptable to excellent range (bladder 0.82, bowel 0.78, prolapse 0.91, and sexual 0.83), showing adequate internal consistency. A comparison of means (≥ 1 point) showed that the questionnaire significantly (p < 0.05) distinguished between women who reported suffering and those who did not. Cohen's kappa for all individual items showed fair to almost perfect agreement (0.24–0.87) between test and retest scores. The intraclass correlation coefficients for domain scores (0.92–0.97) were all in an optimal range. Conclusions The Swedish version of the questionnaire is a reliable and valid instrument for assessing pelvic floor disorders, symptom severity, and impact on quality of life during pregnancy and the postpartum period.
