The Revised Faecal Incontinence Scale possessed evaluative discrimination between different levels of incontinence severity. In this sample it had superior internal consistency and test-retest reliability to the Wexner and St Mark's Incontinence Scales. It was at least as responsive as the Wexner and St Mark's in detecting change in incontinence status following treatment. Although ongoing clinical validation is required, these findings suggest it is a short, reliable, and valid scale that could be considered for use by researchers, epidemiologists, and clinicians.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
