Validation of the "international consultation on incontinence questionnaire urinary incontinence quality of life".

OBJECTIVE: To Validate the International Consultation on Incontinence Questionnaire Quality of Life for the Portuguese population. Urinary incontinence is a highly prevalent condition with a negative impact on people's quality of life. The International Consultation on Incontinence Questionnaire Quality of Life was adapted in order to have a standardized structure that allows the assessment of the impact of urinary incontinence on quality of life. METHOD: An observational cross-sectional study was carried out with two hundred and twenty participants recruited at the Centro Hospitalar de Vila Nova de Gaia/Espinho and at the Centro Hospitalar Universitário de São João during the period from September 2019 to January 2020. The psychometric properties of the questionnaire were assessed. For internal consistency, the standardized Cronbach's alpha coefficient was calculated. In order to obtain construct validity, an exploratory factor analysis was performed using varimax rotation to extract the main components. RESULTS: The Portuguese version of the questionnaire has 21 items distributed by the three factors found, maintaining the items proposed in the original version. The result of standardized Cronbach's alpha coefficient, α=0.906 overall, confirms the internal consistency of the Portuguese version of the instrument. Pearson's correlation analysis was performed between each item and the item assessing the impact on quality of life in the form of a scale, verifying a positive correlation in all items. CONCLUSIONS: The Portuguese version of the questionnaire proved to be reliable and valid in the study carried out for clinical and research use.

RESUMEN Objetivo: Validar la Consulta Internacional sobre Incontinencia Cuestionario de Calidad de Vida para la población portuguesa. La incontinencia urinaria es una condición altamente prevalente conun impacto negativo en la calidad de vida de las personas. Se adaptó el International Consultationon Incontinence Questionnaire Quality of Life para tener una estructura estandarizada que permita evaluar el impacto de la incontinencia urinaria en la calidad de vida. Método: Se realizóunestudio transversal observacional condoscientosveinte participantes reclutados en el Centro Hospitalar de Vila Nova de Gaia/Espinho y en el Centro Hospitalar Universitário de São João durante el período de septiembre de 2019 a enero de 2020. Las propiedades psicométricas delcuestionario. Para la consistencia interna se calculó el coeficiente alfa de Cronbach estandarizado. Para obtener la validez de constructo se realizó una nálisis factorial exploratorio mediante rotación varimax para extraer los componentes principales. Resultados: La versión portuguesa del cuestionario tiene 21 ítems distribuidos por los tres factores encontrados, manteniendo los ítems propuestos en la versión original. El resultado del coeficiente alfa de Cronbach estandarizado, α=0,906 global, confirma la consistencia interna de la versión portuguesa del instrumento. Se realizó el análisis de correlación de Pearson entre cada ítem y el ítem que evalúa el impacto en la calidad de vida en forma de escala, verificándose una correlación positiva en todos los ítems. Conclusiones: La versión portuguesa delcuestionario demostró ser confiable y válida en el estudio realizado para uso clínico y de investigación.

RESUMO Objetivo: Validar o International Consultationon Incontinence Questionnaire Quality of Life para a população portuguesa. A incontinência urinária é uma condição com elevada prevalência e com impacto negativo na qualidade de vida das pessoas. O International Consultationon Incontinence Questionnaire Quality of Life foi adaptado de forma a ter uma estrutura estandardizada e que permite avaliar o impacto da incontinência urinária na qualidade de vida. Método: Foi realizado um estudo observacional do tipo transversal com duzentos e vinte participantes recrutados no Centro Hospitalar de Vila Nova de Gaia/Espinho e no Centro Hospitalar Universitário de São João durante o período de setembro de 2019 a janeiro de 2020. Foram avaliadas as propriedades psicométricas do questionário. Para a consistência interna foi calculado o coeficiente alfa de Cronbach padronizado. Para obter a validade do constructo foi realizada uma análise exploratória fatorial por rotação varimax para extração dos principais componentes. Resultados: A versão portuguesa do questionário tem 21 itens distribuídos pelos três fatores encontrados mantendo, no entanto, os itens propostos na versão original.O resultado de coeficiente alfa de Cronbach padronizado, α=0,906 global, confirma a consistência interna da versão portuguesa do instrumento. Foi realizada a análise da correlação de Pearson entre cada item e o item de avaliação do impacto na qualidade de vida em forma de escala verificando-se uma correlação positiva em todos os itens. Conclusões: A versão portuguesa do questionário, mostrou-se confiável e válida no estudo realizado para utilização na clínica e na investigação.
