LINGUISTIC VALIDATION OF JAPANESE VERSION OF PROLAPSE/URINARY INCONTINENCE SEXUAL QUESTIONNAIRE, IUGA-REVISED (PISQ-IR)

PURPOSE: To translate the Prolapse/Urinary Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR) into Japanese and evaluate the linguistic validation of the translated PISQ-IR. METHODS: The translation and evaluation of PISQ-IR were performed through 3 steps: forward translation based on 2 urologists and discussed by another 4 urologists, 1 pharmacoeconomist and 1 nurse; the community review process consists of conducting one-on-one cognitive interviews with 20 patients by a professional interviewer; backward translation by a native English speaker, which was negotiated with the PISQ-IR Working Group comprised original authors in International Urogynecological Association (IUGA). RESULTS: The PISQ-IR Working Group generally approved our translation and had 2 major concerns in the Japanese version; 1) "disagree" in every sentence of English version was not translated into Japanese, and 2) the Japanese expression in "sexual desire" should be more emotional. The former concern was approved by explaining that Japanese does not have the word which is the equivalent of "disagree", and "don't agree" is always used instead of "disagree". The latter concern was compromised by switching to a translation using emotional words. CONCLUSION: The Japanese version of PISQ-IR was translated in a linguistically valid manner. It would be equivalent to the original English questionnaire. It may provide a tool to assess sexual function for Japanese women with prolapse, urinary incontinence and/or fecal incontinence in an internationally harmonized fashion.
