Urinary incontinence (UI) and pelvic organ prolapse (POP) significantly decrease quality of life and sexual health. This study aimed to evaluate the reliability and validity of a Serbian adaptation of the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12) used in assessing sexual function in women with UI and/or POP.
This study included 416 women, 310 (74.5%) with UI and/or POP and 106 (25.5%) without UI and/or POP. The adaptation of the PISQ-12 to Serbian language was performed via back-translation. The content validity of the questionnaire was conducted by experts in the field. The reliability and validity of the PISQ-12 were analyzed. Evaluation of the data was performed using Content Validity Index (CVI), Cronbach's alpha, test-retest reliability, item total correlation and confirmatory factor analysis.
Content validity of the Serbian PISQ-12 was 1.00 (100%). Item total correlations were between 0.459 and 0.819 (P < 0.001). The PISQ-12 had an adequate and high internal consistency (Cronbach's alpha 0.806) as well as high test-retest reliability (Pearson correlation coefficient r = 0.807; P < 0.001). Factor analysis results revealed strong construct validity. The mean scores of PISQ-12 were significantly better in the control group compared with the women with UI and/or POP. Sexual function was negatively affected by UI and/or POP as assessed with SF-36 and I-QoL questionnaires.
This study showed that the Serbian version of the PISQ-12 is a reliable, consistent, valid and condition-specific instrument to assess sexual function in women with UI and/or POP.
