Abstract Background: Rasch analysis is a statistical model that can be used in the development of new assessment tools and the evaluation of already existing ones. Rasch analysis can also be used to provide various forms of construct validity evidence. In the revised conceptualization of validity, validity is operationalized as a unitary concept with five types of evidence. This article aims to inform rehabilitation practitioners of the different forms of validity evidence that can be demonstrated using Rasch analysis.
