Systèmes d'Information et Management


Social Networking Sites (SNS) have grown exponentially. They may nevertheless induce negative effects on the individuals and the organizations that are now capturing the inter- est of an emerging body of research. The aim of this article is to provide an understanding of one of these effects: the dependence phenomenon on these platforms. An extensive liter- ature review in management information systems and psycho-sociology is mobilized and helped developing an original explanatory model which stipulates that perceived useful- ness, along with perceived behavioral control may contribute to install usage habits and information overload. These, jointly and under the effect of social influence may in turn induce perceived dependence on SNS. The model is tested using the PLS method applied to structural equation modeling on data collected via an online survey within a population of 248 Facebook users. Findings confirm the central role played by habit and information overload in this mechanism, with regard to the type of usage adopted (professional/pri- vate) and to the gender effect which has appeared to be significant. The managerial and theoretical implications of the study, the limitations and also the new research areas to which it can open the path are then discussed.
