Abstract
Introduction and hypothesis
The International Consultation on Incontinence Questionnaire Overactive Bladder Symptoms Quality of Life (ICIQ-OABqol) Module evaluates the quality of life of individuals with overactive bladder (OAB) symptoms, and its use in scientific studies and clinical practice is recommended by the International Continence Society. The aim was to conduct the cross-cultural adaptation and validation of the Brazilian Portuguese version of the ICIQ-OABqol (ICIQ-OABqol_portuguese) in individuals with OAB symptoms.
Methods
An observational cross-sectional study was performed at the Clinical Physiotherapy of PUC MINAS in Belo Horizonte, MG, Brazil, between March 2017 and October 2018. The translation was previously carried out by the Mapi Research Institute. After receiving the translated questionnaire, the cross-cultural adaptation process was conducted as follows: (1) review by an expert committee (13 experts); (2) pre-test (n = 30); (3) cross-cultural adaptation; (4) validation of the ICIQ-OABqol_portuguese. We analyzed the intraexaminer reliability validation (n = 118) and internal consistency measurement (Cronbach’s α coefficient), test-retest reliability (ICC) and correlation between the ICIQ-OAB and ICIQ-OABqol_portuguese questionnaires through Pearson’s correlation coefficient and Bland-Altman scatter plot and concordance. Confirmatory factor analysis was used to confirm the domains of the instrument.
Results
The ICIQ-OABqol was cross-culturally adapted to Brazilian Portuguese and presented satisfactory internal consistency (α-Cronbach coefficient 0.88), adequate construct validity, strong reliability considering the test-retest with an interval of 19.68 (±6.98) days and moderate correlation with the ICIQ-OAB.
Conclusions
The Brazilian Portuguese version of the ICIQ-OABqol shows satisfactory psychometric properties and can be used to evaluate the quality of life of individuals of both sexes with OAB symptoms.
