Validation of the international consultation on incontinence modular questionnaire – female lower urinary tract symptoms (ICIQ-FLUTS) into brazilian portuguese

ABSTRACT Purpose: To translate, adapt and validate the International Consultation on Incontinence Modular Questionnaire on Female Lower Urinary Tract Symptoms ICIQ-FLUTS for the Brazilian female population. Materials and Methods: A translation of the questionnaire into Brazilian Portuguese was made followed by an adaptation for better understanding by native speakers. After that, the ICIQ-FLUTS was answered by eighty volunteers (n=80) twice (for interviewers 1 and 2) with an interval of 30 minutes between them. Furthermore, after 15 days from the evaluation, the participants answered the ICIQ-FLUTS again in order to verify the questionnaire stability over time. The questionnaires Utian Quality Of Life (UQOL) and International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), which are validated in Brazil were also applied to perform the validation. Results: The result of the Cronbach α coefficient of the instrument presented a value of 0.832. The values for test-retest were 0.907 (inter-observer) and 0.901 (intra-observer). The correlation between ICIQ-FLUTS (score I - domain of urinary incontinence) with the ICIQ-SF (final score) was strong and positive (r=0.836, p=0.000). In addition, the ICIQ-FLUTS showed moderate and negative correlation with the total score of UQOL (r=-0.691, p=0.017). Conclusion: The Portuguese version of the ICIQ-FLUTS questionnaire showed strong correlation to ICIQ-SF questionnaire and satisfactory values to test-retest and internal consistency.
