Validity and reliability of the Turkish version of the PRAFAB questionnaire in individuals with urinary incontinence

Abstract

PURPOSE: To translate and culturally adapt the Protection, Amount, Frequency, Adjustment, and Body Image (PRAFAB) questionnaire into Turkish and assess its validity and reliability. MATERIALS AND METHODS: 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). RESULTS: < 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. CONCLUSION: Findings support the validity and reliability of PRAFAB-Turkish for assessing UI-related quality of life.Trial registration: ClinicalTrials.gov, NCT07339657.
