Project Title: Factors Influencing Users' Adoption of Technology: Empirical Investigations in Different Contexts using Structural Equation Modeling Approach


Abstract By the fact that technology and its practices have taken place in our lives everyday more than the other days, the factors that affect the user acceptance of technological products and practices have attracted the attention of researchers. Technology Acceptance Model-TAM is used for our practices which are accepted as a cornerstone in this field. In this study, a general technology acceptance model will be attempted to develop, considering Structural Equation Modeling methodology, by enhancing TAM in four different contexts, and by investigating the factors that affect the attitudes of users towards the practices or products in each context, and at the end, by calculating the common factors with cross reference. The study will be implemented by collecting data with e-government, e-health, e-learning and mobile practices. Survey method will be used as a data collection and measurement tool, and the proposed models will be verified which the data is analyzed with Structural Equation Modeling methodology. It is anticipated that the verified models will be a pathfinder for product and application developers in design process. The project duration is 18 months. The development of a comprehensive technology acceptance model valid in four various contexts, together with their validation, will be complete. The Aim of the Project In this Project, four technology adoption models will be developed for different four context; e-government, e-learning, mobile systems, e-health. The models developed for different context will be compared to recognize the requirements of different fields. And then it is aimed to form a general technology adoption model for these contexts. In order to form these models, Structural Equation Modeling (SEM) will be used. We aim to develop models for being guideline for system developers and designers to predict the needs of the end-users during the development stage of systems in these four domains. Also, we hope that, at the end of research the created general adoption model will help to reduce the financial needs and to improve the effectiveness of the development, implementation and continuous improvement stages of the systems. The Scope of the Project Technology Acceptance Model (TAM) is one of the mostly used model in order to evaluate the adoption of end-users towards offered systems. Although, TAM has been criticizing and has been found limited to predict user adoption, it is the most widely used adoption model in the literature. In order to improve the prediction power of the model, external variables added to original TAM in the existing researches of technology adoption. However, there is no study has been conducted that examined different domains (e-government, e-health, e-learning and mobile systems) and compare them in one study. In this project, new external factors will be investigated for different domains, and the common factors that affect users’ adoption will be identified by taking original TAM as a theoretical adoption model. The scope of the project               • To test TAM in different domains and to contribute the literature by providing different researches               • To determine the common factors for different domains by comparing all identified factors in the specified context.              • To investigate the needs of end-users in different domains and identify their needs to help technology providers and system production.



The Institute for Prospective Technological Studies (IPTS) is one of the seven scientific institutes of the European Commission's Joint Research Centre (JRC). IPTS promotes and enables a better understanding of the links between technology, economy and society. Its mission is to provide customer-driven support to the EU policy-making process by developing science-based responses to policy challenges that have both a socio-economic as well as a scientific/ technological dimension.
