Modeling The Longitudinality Of User Acceptance Of Technology With An Evidence-Adaptive Clinical Decision Support System, Michael P. Johnson Jr., Kai Zheng, Rema Padman

Michael P. Johnson

This paper presents multiple innovations associated with an electronic health record system developed to support evidence-based medicine practice, and highlights a new construct, based on the technology acceptance model, to explain end users' acceptance of this technology through a lens of continuous behavioral adaptation and change. We show that this new conceptualization of technology acceptance reveals a richer level of detail of the developmental course whereby individuals adjust their behavior gradually to assimilate technology use. We also show that traditional models such as technology acceptance model (TAM) are not capable of delineating this longitudinal behavioral development process. Our TAM-derived analysis …
