Technology adoption has been studied extensively within the IS discipline. However, few if any have studied end users’ acceptance of newly implemented technologies within organizational contexts before end-users start using the technology. Additionally, information management motivation is one of the areas that have not yet been sufficiently integrated with the technology acceptance literature. The present research investigates the personal information management motivation and its sub-dimensions, such as proactiveness, sharing, transparency, and formality, based on the extant literature from information systems (IS), social psychology, and knowledge management fields, and their relationships to behavioral intention to adopt content management systems in a mandatory setting. The proposed model was empirically tested using the data collected from 148 end users using PLS. The study findings provide important insights on understanding information management motivation in a mandatory adoption environment.
