Abstract
Introduction and hypotheses
The International Continence Society recommends the International Consultation on Incontinence Questionnaire-Bladder Diary (ICIQ-BD) for the assessment, management, and monitoring of lower urinary tract symptoms (LUTS). Translation, cross-cultural adaptation and validation will establish a valid and reliable tool for Brazilian women with LUTS.
Methods
A cross-sectional study involving 101 women was carried out at the Urogynecology Outpatient Clinic in Belo Horizonte, Brazil, between August 2020 and April 2022. The process of cross-cultural adaptation and validation was executed following the ICIQ Group's protocol. Reviewed by an expert committee, the first pre-test was followed by subsequent adaptations, resulting in a second adapted version that underwent expert revisions. A second pretest was conducted, followed by cross-cultural adaptation and construct validation. Finally, the International Consultation on Incontinence Questionnaire-Bladder Diary-Brazilian Portuguese Version (ICIQ-BD-Br) underwent a validation process.
Results
Construct validity (IVC >0.78) and internal consistency were satisfactory (α-Cronbach coefficient 0.87–0.94). The following adjustments were made: a specific field was created to document sleep and wake times, and a printed score ranging from 0 to 4 was included in the bladder sensation column. Test–retest reliability ranged from fair to excellent for all analyzed items (Spearman correlation: 0.64–0.95). Criterion validity analysis indicated slight agreement for one of the four symptoms analyzed (nocturia k=0.32). The final version was approved by the ICIQ Group.
Conclusions
The ICIQ-BD-Br has been adapted for use in Brazilian Portuguese and has exhibited robust construct validity and reliability for Brazilian women with LUTS.
