Purpose The purpose of this study was to translate and culturally adapt the GSE-UI for use with a Turkish population and to determine its validity and reliability. Methods 120 elderly with UI aged 60 and over years (mean 72.89 +/- 9.59 years) participated in this study. An interview was held to determine the type, severity and frequency if any, incontinence. Then, the Mini-Mental State Examination, IIQ-7, UDI-6 and I-QOL questionnaires were administered to the participants. After translating the tool to Turkish, test and retest was performed with an interval of 7-14 days. Results The internal consistency of the first test of the GSE-UI-Turkish was excellent, with a Cronbach alpha of 0.95. The test-retest reliability of the GSE-UI-Turkish was found to be excellent (ICC = 0.94, 95% CI 0.92-0.96). The correlation coefficient between the GSE-UI-Turkish and the UDI-6, IIQ-7, I-QOL were found to be good to excellent (r = 0.68, r = 0.67, r = 0.81, r = 0.45, respectively; p < 0.0001). Conclusion Results of our study GSE-UI of Turkish version, self-efficacy evaluation in geriatric incontinence was a valid and reliable survey that can be used in clinical practice.
