Spanish version of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire IUGA-Revised (PISQ-IR): Transcultural validation

Abstract

Introduction and hypothesis

The aim of this study was to transculturally adapt the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire IUGA-Revised (PISQ-IR) into Spanish and to validate the new version.

Methods

We carried out a two-stage observational cross-sectional study: translation and back-translation, followed by a validation stage in which the final version was administered to 268 consecutive women (118 not sexually active [NSA] and 150 sexually active [SA]) older than 18 from an Urogynecology Unit. Besides PISQ-IR, women also completed the following questionnaires: Incontinence Severity Index (ISI); Female Sexual Function Index (FSFI); Pelvic Floor Distress Inventory (PFDI-20); and question #35 from the Epidemiology of Prolapse and Incontinence Questionnaire (EPIQ). Feasibility (percentage of valid cases), internal consistency (Cronbach’s alpha), and construct validity (structural, by factor analysis, and convergent validity by Spearman’s Rho) were evaluated.

Results

The sample was formed by 118 NSA and 150 SA women, with a mean age (SD) of 59.2 (11.5) years; mean body mass index (BMI) of 29.6 kg/m2 (5.6), and mean parity of 2.6 deliveries (1.2). PISQ-IR showed a high response rate (98.3% NSA and 94.7% SA), and elevated internal consistency (Cronbach’s alpha for NSA and SA of 0.79 and 0.91 respectively). Factor analysis confirmed the structure of the original questionnaire and the convergent validity showed moderate to strong correlation between PISQ-IR and the ISI, PFDI-20, and FSFI scores, in addition to item #35 of the EPIQ.

Conclusions

The Spanish version of the PISQ-IR has adequate psychometric properties; therefore, it can be a useful tool for assessing sexual function in women with pelvic floor disorders.
