Abstract

Introduction and hypothesis

Our objective was to translate and validate a Portuguese version of the Urinary Incontinence-Specific Quality-of-Life Instrument (I-QOL), a questionnaire that is widely used in clinical trials.

Methods

Fifty patients completed the same questionnaire twice at a 2-week interval. During the first visit, we conducted a face-to-face interview and collected demographic data. The King's Health Questionnaire was completed during the same visit for comparisons.

Results

The results showed that the Portuguese version of the I-QOL has very good psychometrics properties. Reliability was assessed by Cronbach's alpha (0.93), reproducibility was calculated through the intraclass correlation coefficient (0.88), construct validity was determined by comparing the I-QOL scores and King's Health scores, and discriminant validity was calculated by comparing the total I-QOL scores with measures of gravity.

Conclusions

We conclude that the Portuguese version of the I-QOL is a very good tool for the evaluation quality-of-life in women with urinary incontinence in Portuguese-speaking countries.
