Abstract
INTRODUCTION AND HYPOTHESIS: Despite the widespread use of UDI-6 and ICIQ-UI SF in Croatia, it remains unknown whether a realiable and valid measure for the population of interest is used. Thus, the aim of this study was to translate, adapt and validate the UDI-6 and the ICIQ-UI SF in Croatia. METHODS: The study included a total of 232 consecutive patients with urinary incontinence symptoms. The translation to Croatian followed standardized procedure. All participants underwent urodynamic assesment and completed UDI-6 and ICIQ-UI SF questionnaires at inclusion and 2 weeks after to assess test-retest reliability. Cronbach α coefficient was calculated in order to assess internal consistency. RESULTS: Both questionnaires had high internal consistency (Cronbach α for UDI-6 and ICIQ-UI SF was .83 and .85, respectively) and high test-retest reliability (intraclass correlation coefficient .99 for instruments). Strong correlation was found between urodynamic findings and total scores in UDI-6 and ICIQ-UI SF (ρ = 0.88 and 0.89, respectively). Women with stress urinary incontinence (SUI) and detrusor overactivity (DOA) group had significantly higher scores on UDI-6 (Mdn = 33.33 and Mdn = 50, respectively) compared to women with no urodynamic abnormality (Mdn = 0; p < 0.001). Women with no urodynamic abnormality scored significantly lower on ICIQ-UI SF (Mdn = 0; p < 0.001) compared to women with SUI (Mdn = 14) and DOA (Mdn = 16). Women with DOA scored worse on Irritative and Obstructive symptoms when comparing with two other groups (p < 0.001), while women with SUI had significantly worse score on Stress symptoms subscale (p < 0.001). CONCLUSIONS: The UDI-6 and ICIQ-UI SF have very good psychometric characteristics and can be used in Croatian urogynecology practice.
