Abstract
To translate and culturally adapt the Protection, Amount, Frequency, Adjustment, and Body Image (PRAFAB) questionnaire into Turkish and assess its validity and reliability.
Content validity was assessed using the item-level content validity index (I-CVI) and the scale-level content validity index based on the average method (S-CVI/Ave). Validity analyses included exploratory factor analysis (EFA), convergent validity, known-groups validity, and floor and ceiling effects. Reliability included internal consistency, corrected item-total correlations, and test-retest reliability using a two-way mixed-effects intraclass correlation coefficient (ICC).
The study included 63 women with urinary incontinence (UI) and 51 healthy women (mean age: 52.54 ± 13.33 years). After revision, all I-CVIs and S-CVI/Ave were 1.00. EFA suggested a unidimensional structure in this sample, explaining 52% of variance, with loadings ≥0.598. PRAFAB-Turkish correlated strongly with UI scales (p < 0.001) and discriminated between groups (p < 0.001). Corrected item-total correlations exceeded 0.542. Internal consistency (Cronbach's α = 0.824) and test-retest reliability (ICC = 0.990) were good and excellent, respectively. Standard error of measurement (SEM), SEM%, minimum detectable change (MDC), and MDC% values were 0.372, 2.97%, 1.031, and 8.22%, respectively.
Findings support the validity and reliability of PRAFAB-Turkish for assessing UI-related quality of life.Trial registration: ClinicalTrials.gov, NCT07339657.
