The study is to translate the Medical, Epidemiologic, and Social aspects of Aging (MESA) urinary incontinence questionnaire into a Chinese language version and test the reliability and validity among women with urgency-predominant mixed urinary incontinence.

The hypothesis is that the Chinese language version of the MESA questionnaire will have adequate measurement properties (e.g. reliability and validity).

Mixed urinary incontinence(MUI) is regarded as urgency-predominant when urgency incontinence episodes dominate over stress incontinence episodes, and vice versa. The treatment of MUI often begins with the most bothersome symptoms.

MESA questionnaire is a reliable and validated tool to evaluate the severity and predominance of stress or urgency urinary incontinence. At present, it hasn't been translated into a Chinese language version and validated.

The validation study of MESA questionnaire is embedded in a randomized controlled trial conducted among female patients, of which the data will be collected and analysed.
