Objective: To Validate the International Consultation on Incontinence QuestionnaireQuality of Life for the Portuguese population. Urinary incontinence is a highlyprevalent condition with a negative impact on people’s quality of life. The International Consultation on Incontinence QuestionnaireQuality of Life was adapted in order to have a standardized structure thatallows the assessment of the impact of urinary incontinence on quality of life.Method: An observational cross-sectional study was carried out with two hundredand twenty participants recruited at the CentroHospitalar de Vila Nova de Gaia/Espinho and at the CentroHospitalar Universitário de São João during the period from September 2019 to January 2020.The psychometric properties of the questionnaire were assessed. For internalconsistency, the standardized Cronbach’s alphacoefficient was calculated. In order to obtain construct validity, anexploratory factor analysis was performed using varimax rotation to extract themain components. Results: The Portuguese version of the questionnaire has 21 items distributed bythe three factors found, maintaining the items proposed in the originalversion. The result of standardized Cronbach’s alpha coefficient, α=0.906 overall, confirms the internal consistency ofthe Portuguese version of the instrument. Pearson’s correlation analysis was performed between each item and the itemassessing the impact on quality of life in the form of a scale, verifying apositive correlation in all items. Conclusions:ThePortuguese version of the questionnaire proved to be reliable and valid in thestudy carried out for clinical and research use.
