The purpose is to develop linguistic validation of the PFDI-20 and PFIQ-7 questionnaires. Three types of Korean version of questionnaires have been used in four locations of University Hospitals in Korea. Each version of questionnaires was developed by forward translation and back-translation by bilingual translators and was verified by the patients with pelvic floor disorder and healthy persons. For harmonization of 3 types of questionnaires, four authors reviewed, discussed all discrepancies, incorporated and produced a new version. The multi-step processes of translation and linguistic validation of the Korean version of PFDI-20 and PFIQ-7 questionnaire were completed. Further process of validation of Korean version of these questionnaires is required.
