Abstract
Objectives: Urinary incontinence (UI) can affect up to 50% of the population of women over the age of 50. In order to objectively assess discomfort in women with UI prior to initiating treatment and monitoring the outcomes of the treatment, validated questionnaires need to be used to examine the impact of UI on health-related quality of life (HR-QoL). The Urogenital Distress Inventory — Short Form (UDI-6) and the Medical Epidemiologic and Social Aspects of Ageing (MESA) questionnaires are used typically. Assessment of the Polish translation of the MESA and UDI-6 questionnaires. Material and methods: 155 patients with symptoms of UI were enrolled. Each of the patients completed the MESA and UDI questionnaires prior to being examined. The final diagnosis was made after diagnostic tests were carried out in the patients. Results: Principle component analysis showed division of the Polish versions of the questionnaires into domains identical to the original version. Analyses of internal consistency reliability revealed high internal consistency for the MESA questionnaire (0.90) and a low reliability of the UDI-6 questionnaire (0.44). Conclusions: The Polish version of the MESA questionnaire was demonstrated to be a clinically useful diagnostic tool in the studied population, UDI-6 did not reached a sufficiently high reliability in the study group to be recommended as a diagnostic tool.
