Iranian Translation of the Prolapse and Incontinence Knowledge Questionnaire: Validity and Reliability.

Area of Science:

• Urogynecology
• Medical Education
• Psychometrics

Background:

• Urinary incontinence (UI) and pelvic organ prolapse (POP) are prevalent conditions affecting women's quality of life.
• Assessing patient knowledge is crucial for effective management and treatment adherence.
• The Prolapse and Incontinence Knowledge Questionnaire (PIKQ) is an established tool for evaluating this knowledge.

Purpose of the Study:

• To translate the PIKQ into Persian.
• To evaluate the validity and reliability of the Persian version of the PIKQ for use in an Iranian population.

Main Methods:

• A descriptive cross-sectional study involving 205 women was conducted.
• Standardized translation and back-translation methods were employed for the Persian version.
• Psychometric properties, including content validity, construct validity (confirmatory factor analysis), and reliability (test-retest, KR-20), were assessed.

Main Results:

• Confirmatory factor analysis indicated acceptable model fit for both UI and POP components after item refinement, though original items were retained.
• Convergent validity was confirmed with Average Variance Extracted (AVE) reaching 0.5 for PIKQ-UI.
• Reliability was good, with intraclass coefficients of 0.852 for PIKQ-UI and 0.646 for PIKQ-POP, and KR-20 values of 0.775 and 0.756, respectively.

Conclusions:

• The Persian version of the PIKQ demonstrates good validity and reliability.
• This translated tool is suitable for assessing knowledge regarding UI and POP among Persian-speaking women.
• The PIKQ can be utilized to enhance patient understanding and educational interventions for these conditions.
