Aim: The purpose of this methodological study is to evaluate the reliability and validity of a Turkish adaptation of the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12) used in assessing sexuality function in women with POP/UI.
Methods: The PISQ-12 was translated into Turkish; the adaptation of the PISQ-12 to Turkish language was performed via back-translation, the content validity of the questionnaire was conducted by experts in the field, test-retest reliability was examined with 40 women with UI and/or POP. PISQ-12 was administered to 120 women with pelvic floor dysfunction. 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.
Results: CVI of the Turkish PISQ-12 was found 1.00 (% 100). Item-total correlations were between 0.42 and 0.68 (P < 0.001). The PISQ-12 had an adequate and high internal consistency (Cronbach's α = 0.74) as well as a high test-retest reliability (Pearson correlation coefficient, r = 0.961; P < 0.001). Factor analysis results revealed strong construct validity.
Conclusion: The Turkish version of the PISQ-12 is a reliable, consistent and valid instrument to assess sexual function in women with urinary incontinence and/or pelvic organ prolapse. It is also a comprehensive and easily applicable instrument which as a treatment outcome or research tool in clinical practices.
