[Linguistic validation of Japanese version of Prolapse/Urinary Incontinence Sexual Questionnaire, IUGA-Revised...

Area of Science:

• Urogynecology
• Sexual Health Research
• Cross-cultural Adaptation of Medical Instruments

Background:

• Pelvic organ prolapse and urinary incontinence significantly impact women's quality of life, including sexual function.
• Standardized questionnaires are crucial for evaluating treatment outcomes and understanding patient experiences.
• The Prolapse/Urinary Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR) is a validated tool for assessing sexual function in women with these conditions.

Purpose of the Study:

• To translate the PISQ-IR into Japanese.
• To linguistically validate the Japanese version of the PISQ-IR for use in Japanese women.
• To ensure the translated questionnaire accurately reflects the original instrument's intent and meaning.

Main Methods:

• The translation process involved forward translation by urologists and review by a multidisciplinary team.
• Community review included cognitive interviews with 20 patients to assess comprehension.
• Backward translation and negotiation with the original PISQ-IR Working Group ensured accuracy and cultural appropriateness.

Main Results:

• The PISQ-IR Working Group approved the translation, with minor adjustments made for cultural nuances.
• Concerns regarding the translation of "disagree" were addressed by explaining linguistic differences.
• The expression for "sexual desire" was refined to be more emotionally resonant in Japanese.

Conclusions:

• The Japanese version of the PISQ-IR is linguistically valid and equivalent to the original English version.
• This validated tool can now be used to assess sexual function in Japanese women with prolapse and/or incontinence.
• It facilitates internationally harmonized assessment of sexual health in this patient population.
