Introduction and hypothesisThe use of validated Quality of Life (QoL) questionnaires is useful in the standardization and interpretation process of pelvic floor patient symptoms, due to their functional nature and high prevalence. The Pelvic Floor Distress Inventory QoL questionnaire (PFDI-20) serves both as a symptom inventory and a measure of the degree of bother and distress caused by pelvic floor symptoms. It includes items related to pelvic organ prolapse and lower gastrointestinal and bladder dysfunction.MethodsAfter consensus translation and a comprehension test, the Italian version of the questionnaire was submitted to patients reporting bowel, bladder, or pelvic disorders (cases) and to asymptomatic women (controls). Cases received the questionnaire once again 2 weeks later by email.ResultsA total of 254 patients answered the questionnaire. Construct validity was demonstrated by discriminating between cases and controls. Convergent validity was demonstrated for each domain (F < 0.001). In-ernal consistency reliability showed a satisfactory range (0.816-0.860).ConclusionsThe PFDI-20 allows a comprehensive assessment of the effect of pelvic floor disorders on the quality of life of women. Moreover, the PFDI-20 represents a very solid QoL tool, since it has been extensively used in literature, and its use is highly recommended by the International Consultation on Incontinence. The present study demonstrated good features for the Italian version of the PFDI-20 questionnaire.
