Abstract: INTRODUCTION AND HYPOTHESES: Pelvic floor disorders (PFDs) affect women's quality of life through physical, psychological, and social domains. The Pelvic Floor Distress Inventory-20 (PFDI-20) and the Pelvic Floor Impact Questionnaire-7 (PFIQ-7) are validated tools for assessing symptom severity and quality of life impact. The current study aim to investigate the reliability and validity of the Hungarian versions of these questionnaires in women with PFD symptoms. METHODS: This validation study was carried out at the University of Debrecen among women with clinically confirmed pelvic floor disorders. The PFDI-20 and PFIQ-7 questionnaires were translated into Hungarian using independent native English speaker in the back- translation process. Psychometric testing included internal consistency (Cronbach's alpha), test-retest reliability (ICC), and construct validity using the SF-36 Health Survey. The tools were valid and reliable for assessing pelvic floor symptoms and their impact on the quality of life in Hungarian women. RESULTS: One hundred fifty patients completed the Hungarian PFDI-20, PFIQ-7, and SF-36 questionnaires for psychometric evaluation. Both Hungarian versions showed excellent internal consistency (PFDI-20 α = 0.885; PFIQ-7 α = 0.939) and strong test-retest reliability (PFDI-20 ICC = 0.903; PFIQ-7 ICC = 0.933). DISCUSSION: The Hungarian versions of the PFDI-20 and PFIQ-7 questionnaires demonstrated excellent reliability, validity, and cultural relevance for assessing symptom severity and quality of life in women with pelvic floor disorders. Strong internal consistency, high test-retest reliability, and significant correlations with the SF-36 support their psychometric soundness. These tools are suitable for both clinical and research applications in Hungarian-speaking populations.
