The objectives of this research were to develop and to examine an integrated model for Web-based Learning system (WBLS) adoption by Computer and Information Technology (CIT) instructors in Thai universities. To achieve these objectives, the integrated model of this research was developed by incorporating four existing models and theories (i.e. Technology Acceptance Model, Delone & McLean IS success model, Diffusion of Innovations theory, and theory of planned behavior). The survey data were collected from 295 CIT instructors in Thai universities, and, then, were analyzed by using the structural equation modeling in order to verify the proposed model. The results showed that the proposed model was consistent with the empirical data, and accounted for 81.10% of variance in WBLS adoption. The results, moreover, showed that factors affecting WBLS adoption of CIT instructors in Thai universities, sorted in descending order by their total effect sizes, were intention to use, system quality, information quality, perceived usefulness, perceived ease of use, compatibility, service quality, and computer self-efficacy.
