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 PPOP 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.... Show more Show less
