This paper introduces the research model of user intention to continue adopting information in an online discussion forum. The model is built upon the information adoption model and the IS continuance model. Since the focus of this study is on continuance intention, the model takes user evaluation process into account and includes some important constructs (satisfaction, information quality, source credibility, and information usefulness) to explain the continuance behavior. An online survey was conducted and a total of 315 completed questionnaires were collected. Among the 315 respondents, 144 respondents have adopted the information in an online discussion forum. The research model explains 60% of the variance. The results also provide strong support for the existing theoretical links, as well as for those newly hypothesized in this study.
