Introduction and hypothesis: The primary aim of the study was to translate and validate a Polish version of the CONTILIFE, a quality of life questionnaire. The clinical validity of the CONTILIFE was assessed against the number of urinary leaks, Valsalva leak point pressure (VLPP), and maximum urethral closure pressure (MUCP).
Methods: One hundred women with stress urinary incontinence completed a Polish version of the CONTILIFE twice with a 4-day interval.
Results: Internal consistency (Cronbach's alpha= 0.94) and test-retest reliability of the instrument (ICC = 0.96) were very good. A significant relationship was found between all the CONTILIFE dimension scores, the CONTILIFE global score, and the number of urinary leaks per week. A less significant relationship was found between VLPP, MUCP, and CONTILIFE dimension and global scores.
Conclusions: A Polish version of the CONTILIFE can be a reliable measure of quality of life in stress urinary incontinence patients.
