Cutoff score of the traditional Chinese version of the short form of the pelvic organ prolapse/urinary incontinence sexual questionnaire (PISQ-12)

Abstract

Objective: The short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) is a condition-specific instrument used to evaluate sexual function in women with pelvic floor disorders. The traditional Chinese version of the PISQ-12 (CVPISQ-12) has been validated, however the cutoff score has yet to be determined. The aim of this study is to establish the cutoff score for the CVPISQ-12 and analyze the risk factors for female sexual dysfunction. Material and methods: A sub-analysis of data involving sexually active women who sought consultation for pelvic floor disorders at a medical center in 2016. Based on the known cutoff value of Female Sexual Function Index, the cutoff score of the CVPISQ-12 was analyzed using receiver operating characteristic (ROC) curve analysis. Other assessments included 1-h pad test and incontinence-related questionnaires using the short forms of the Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7). Results: ROC curve analysis showed a cutoff score of 32.5, with a sensitivity of 87% and specificity of 88%. The area under the ROC curve was 0.937 (p <0.001; 95% confidence interval: 0.895–0.979). The 1-h pad test (B = −0.266; p = 0.031), IIQ-7 (B = −0.378; p = 0.047) and age (B = −0.415; p = 0.001) were risk factors for sexual dysfunction in women with a score <32.5. However, age was the only significant risk factor for women with a higher score (B = −0.384; p = 0.035). Conclusions: A CVPISQ-12 score ≥32.5 suggested normal sexual function. For this patient group, age may be a more important factor associated with sexual function than pelvic floor disorders.
