Aims: To analyze the psychometric properties of instruments measure knowledge and/or attitude and/or practice related to urinary incontinence (UI)., Methods: This review was conducted in September 2018 without restrictions regarding language and year of publication., Data Sources: MEDLINE/PubMed, CINAHL, SCOPUS, PsycINFO, Web of Science, Cochrane, LILACS, and Google. The psychometric properties were evaluated using the COnsensus-based Standards for the selection of health status Measurement INstruments and the Quality Criteria for Measurement Properties., Results: A total of seven articles published between 1999 and 2018 were included. The evaluation of the psychometric properties showed that the majority of the instruments presented "excellent" or "good" methodological quality; however, the description of aspects related to the validation stages was inadequate in some studies, causing the quality of the results to be evaluated as "indeterminate" in some properties. This review cannot recommend any questionnaire without reservations; however, the Urinary Incontinence Scales and the Barriers Incontinence Care Seeking Questionnaire presented better evaluations, regarding both methodological quality and the quality of the results., Conclusion: This review provides a strategy to select the most suitable instrument to assess knowledge, attitude, and practice regarding UI, according to the psychometric properties, guiding their use by researchers in clinical practice., (© 2019 Wiley Periodicals, Inc.)
