Hypothesis
To investigate the factor structure, dimensionality and construct validity of the PRAFAB questionnaire score in women with stress urinary incontinence.
Conclusion
The findings suggest a two-factorial structure of the PRAFAB questionnaire, confirming its internal consistency and construct validity.
Supporting Evidence
- The PRAFAB questionnaire combines objective and subjective aspects of urinary incontinence severity.
- The two subscales demonstrated adequate internal consistency with Cronbach's alphas ranging from 0.78 to 0.84.
- Higher total PRAFAB scores were expected in patients referred by urogynaecologists compared to those referred by GPs.
Takeaway
The PRAFAB questionnaire helps understand how bad urinary incontinence is for women and how it affects their lives, showing two main areas: how much they leak and how it makes them feel.
Methodology
A cross-validation study design was used with a cohort of 279 patients, divided into two samples for exploratory and confirmatory factor analyses.
Limitations
The generalization of the two-factor solution for different types of UI or other populations is still unclear.
Participant Demographics
Mainly Caucasian women (96%) aged 18 and older with stress urinary incontinence.
