Cross-cultural adaptation and validation of the Urinary Incontinence Scale After Radical Prostatectomy for the Brazilian context.

OBJECTIVE

To translate, adapt, and validate the Urinary Incontinence Scale After Radical Prostatectomy for Brazil.

METHOD: Methodological study: cross-cultural adaptation (translation, synthesis, back translation, expert committee (n=25), pre-testing (n=40) and presentation to original authors) and evaluation of measurement properties (n=80). Data were collected between January 2018 and February 2019 in an oncology unit. The calculated measurement properties: structural validity, hypothesis testing, criterion validity and reliability.

RESULTS

The Brazilian version was called Escala de Incontinência Urinária Pós-Prostatectomia Radical. One item was excluded due to low factor loading (0.322). A significant correlation was identified between the total score of the scale and instruments applied (p<0.001). Incontinent men had higher scores on the total scale in relation to continents (p<0.001). Cronbach's alpha was 0.94 and composite reliability was 0.97.

CONCLUSION

The Brazilian version was considered valid and reliable for the assessment of urinary incontinence in prostatectomized patients.
