Identification of the pelvic organ prolapse/incontinence sexual questionnaire—IUGA revised (PISQ-IR) cutoff scores for impaired sexual function in women with pelvic floor disorders

Abstract

The aim of this cross-sectional study was to determine the cutoff scores for sexual dysfunction in disease-specific Pelvic Organ Prolapse/Incontinence Sexual Questionnaire—IUGA Revised (PISQ-IR) for women with pelvic floor disorders (PFD). Medical history and urogynecological data of 521 women with PFD were collected. The subjects provided information about their sexual activity and completed Female Sexual Function Index (FSFI) and PISQ-IR questionnaires. Sexually active (SA) women were further analyzed and categorized using their FSFI scores: <26.55—sexual dysfunction, >26.55—no sexual dysfunction. Receiver operating characteristics (ROC) curve tested how well PISQ-IR allowed to discriminate between patients with and without sexual disorders. Area under curve (AUC) was calculated to measure the PISQ-IR Summary Score efficiency in the prediction. The cutoff values which minimalize (1-specifity) and maximize sensitivity were selected. In the analyzed cohort, 250 (48%) women were SA and a total of 226 SA were recruited for the study: 143 (63.3%) with <26.55 FSFI and 83 (36.7%) with >26.55 FSFI (response rate: 90.4%). Using ROC curve analysis, PISQ-IR Summary Score of 2.68 was determined to be the optimal cutoff for distinguishing between dysfunctional and nondysfunctional women (AUC = 0.85), allowing to diagnose sexual dysfunction in SA women with PFD, with 90% sensitivity and 71% specificity.
