Understanding information technology acceptance by individual professionals: Toward an integrative view

Abstract

Although information technology is becoming a vital part of the workplace of skilled professionals, it is unclear what factors contribute to its acceptance by them. Building upon and integrating the key findings of three closely related theoretical paradigms (the technology acceptance model, the theory of planned behavior, and innovation diffusion theory), we developed a more complete, coherent, and unified model and tested the resulting model in the context of PDA acceptance by healthcare professionals. Using LISREL, data collected from 222 physicians in the U.S. were tested against the model; it explained 57% of the physician's intention to accept an innovation, with good model fit. Our study produced useful insights into the factors that influence technology acceptance decisions by professionals and provided new ideas in the understanding of user acceptance of technology.
