Validation of a Mandarin Chinese version of the pelvic organ prolapse/urinary incontinence sexual questionnaire IUGA–revised (PISQ-IR)

Introduction and hypothesis: Sexual dysfunction has a high prevalence in women with pelvic organ disorders. Until recently, there has been no single one questionnaire translated or validated that can evaluate the sexual function of patients with a pelvic floor disorder, either for sexually active or inactive women. The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire IUGA–Revised (PISQ-IR) was developed to fill this gap. The aim of this study was to translate and validate the Mandarin Chinese version of PISQ-IR for global use. Methods: This study was conducted with a sample of 106 patients. The PISQ-IR was translated and back-translated by two bilingual urogynecological specialists, and the Mandarin Chinese version was approved by the PISQ-IR Working Group of the International Urogynecological Association (IUGA). Its reliability was assessed using test–retest reliability and internal consistency, and its criterion validity was assessed in relation to other currently valid Chinese questionnaires. Both exploratory and confirmatory factor analyses were assessed. Results: The mean age of the participants was 52 ± 10.6 years. The Cronbach alpha value for each subscale ranged from 0.65 to 0.84 and from 0.6 to 0.83 for the sexually active and inactive groups, respectively. The convergent validity test showed that the value of each subscale was positively correlated with those of other questionnaires (P < 0.05). Exploratory and confirmatory factor analysis illustrated both good factor extraction and model fit. Conclusion: This study demonstrated the Mandarin Chinese version of PISQ-IR is a valid, reliable and condition-specific instrument to assess sexual function in sexually active or inactive women with a pelvic floor disorder.
