Cross-Cultural Adaptation and Validation of the ICIQ-BD for Brazilian Women With Lower Urinary Tract Symptoms.

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.

Bladder training compared to bladder training associated with pelvic floor muscle training for overactive bladder symptoms in women: A randomized clinical trial.

AIMS: To compare the effects of bladder training (BT) versus BT with pelvic floor muscle training (PFMT) in women with overactive bladder (OAB) symptoms. METHODS: Randomized controlled clinical trial including women with OAB symptoms, randomized into two groups: BT versus BT + PFMT. For 12 consecutive weeks, the women received home BT. The BT + PFMT performed supervised PFMT, once/week, associated at home PFMT protocol. Primary outcomes were urinary urgency, daytime voiding frequency, nocturia and urgency urinary incontinence assisted by both 3-day bladder diary and International Consultation on Incontinence OAB (ICIQ-OAB) questionnaire. Secondary outcomes were 24-h pad test and Patient Global Impression of Improvement. T-test, analysis of variance, Mann-Whitney (SPSS 20.0) and power/effect size (G-power) were applied in data analyses. RESULTS: Sixty-three women were included (B = 31; BT + PFMT = 32). There was no significant statistical difference between groups in terms of urinary symptoms: daytime frequency (BT: pre: 11.59 [±5.80], post: 9.10 [±4.05]; BT + PFMT: pre: 10.67 [±3.73], post: 8.08 [±3.38]) p = 0.75; nocturia: (BT: pre: 1.46 [±0.91], post: 0.82 [±0.82]; BT + PFMT: pre: 1.80 [±2.26], post: 0.82 [±1.15]) p = 0.70; urinary urgency (BT: pre: 3.22 [±4.70], post: 4.49 [±4.32]; BT + PFMT: pre: 6.87 [±5.60], post: 6.15 [±4.52]) p = 0.10; ICIQ-OAB total score: (BT: pre: 9.16 [±2.55], post: 6.32 [±3.77]; (BT + PFMT: pre: 9.75 [±2.06], post: 5.06 [±3.44] p = 0.30. CONCLUSIONS: Supervised PFMT added to BT did not provide further improvements than isolated BT in women with OAB symptoms.

The Brazilian Portuguese version of the ICIQ-OABqol: cross-cultural adaptation and reliability.

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.
