The purpose of this article is to
present the clinician and researcher with a contemporary 8-stage framework for
measurement scale development based on a mixed-methods qualitative and
quantitative approach. Core concepts related to item response theory are
presented. Qualitative methods are described to conceptualize scale constructs;
obtain patient, family, and other stakeholder perspectives; and develop item
pools. Item response theory statistical methodologies are presented, including
approaches for testing the assumptions of unidimensionality, local independence,
monotonicity, and indices of model fit. Lastly, challenges faced by scale
developers in implementing these methodologies are discussed. While
rehabilitation research has recently started to apply mixed-methods qualitative
and quantitative methodologies to scale development, these approaches show
considerable promise in advancing rehabilitation measurement.
