Keynote webinar | Spotlight on sleep in brain health

LIVE: Thursday 2nd May 2024, 18:00-19:30 (CEST)

Quality sleep is essential for health. But what happens to our brains when sleep patterns are disturbed? Join our experts to explore the interplay between sleep disruption and neurological diseases, and the questions that you need to be asking your patients to help you prevent the harmful effects of sleep deprivation.

Abstract

Introduction and hypothesis

To translate the Prolapse and Incontinence Knowledge Questionnaire (PIKQ) into Turkish and test its validity and reliability.

Methods

The study included 341 women. The translation of the PIKQ, which comprised of the urinary incontinence (PIKQ-UI) and pelvic organ prolapse (PIKQ-POP) sections, was performed in accordance with international recommendations. The Incontinence Quiz (IQ) and the Visual Analog Scale (VAS) were applied to assess the level of knowledge about POP and UI. Psychometric analyses consisted of assessing the following: (1) construct validity by confirmatory factor analysis, (2) criterion and known group validity, (3) internal consistency reliability by the KR-20 coefficient, and (4) test-retest reliability over 1 week with the intraclass correlation coefficient (ICC).

Results

All fit indices except the Standardized Root Mean Square Residual indicated acceptable fit for the final models. Criterion validity was supported by moderate correlations between the PIKQ-UI and the IQ (rho = 0.679, p < 0.001). There were positive and weak linear correlations between the PIKQ-UI and PIKQ-POP scores and their corresponding perceived knowledge scores (rho = 0.351, p = 0.013 and rho = 0.345, p = 0.014, respectively). The known group validity did not show differences indicating that participants did not have enough knowledge about UI and/or POP even when they had the condition or acquaintance with them (p = 0.852 and p = 0.185, respectively). Reliability was excellent as indicated by the ICCs of 0.91–0.90, and KR-20 of 0.67–0.75 indicated good internal consistency for the PIKQ-UI and PIKQ-POP, respectively.

Conclusions

The Turkish version of the PIKQ is a valid and reliable instrument to assess the knowledge of UI and POP.
