Integrating Diffusion of Innovations and Theory of Reasoned Action models to predict utilization of information technology by end-users

This paper reports on a field study investigating the adoption of an information technology (IT) by end-users. First, based on theories and empirical findings from research into the Diffusion of Innovations and the Theory of Reasoned Action a model was developed of the factors influencing individual level decisions to use IT. The model was then field tested in a survey of 540 individuals in seven organizations. Results show that the model received good support and that it can be used for understanding the utilization of IT. Both one’s own attitude and the expectations of others influenced the degree to which one used IT after adoption. Consistent with results from diffusion research, the most significant perceptions that had an effect on degree of use were ease of use, relative advantage and compatibility.
