The buffering effect of flow experience on the relationship between overload and social media usersxe2x80x99 discontinuance intentions Abstract   There is a growing need to understand why users discontinue using social media platforms. Understanding the antecedents of such decisions and the moderators that govern the antecedent effects can help users reach such decisions, and assist service providers in mitigating them. From a theoretical standpoint, there is a need to enrich the theoretical account of social media discontinuance phenomena. To address these issues, we integrate the xe2x80x9cstimulusorganismresponsexe2x80x9d (SOR) framework and flow theory. We consequently portray the direct, indirect and moderating roles of flow experience in mitigating discontinuance intentions. We test this model via a survey of 502 WeChat users. The results support the SOR model and indicate that social overload, information overload, and communication overload (stimuli) increase the fatigue feelings (organism) of social media users, which, in turn, increase their social media discontinuance intentions (response). By combining the SOR perspective with flow theory, we show that flow experience not only help reduce usersxe2x80x99 perceptions of fatigue and discontinuance intentions, but also moderate (weaken) the effects of fatigue on discontinuance intentions. Flow experience, therefore, serves as a means to inhibit the formation of social media discontinuance intentions, even when overload and fatigue persist. The present research also has several valuable theoretical and practical implications.

Worker stress in the age of mobile technology: The combined effects of perceived interruption overload and worker control Abstract   Mobile technologies have dramatically increased the number of workrelated interruptions, especially after regular work hours. At the same time, many employees have limited freedom to decide how and when they accomplish their work, a condition that renders the explosion of interruptions especially problematic. This study proposes that perceived interruption overload negatively impacts workrelated technologyusage via workersxe2x80x99 experiences of worklife conflict, a key source of stress, and that this indirect effect is stronger for lower levels of worker control (moderated mediation). Data were collected from 601 knowledge workers and analyzed through Conditional process analysis, which integrates moderation and mediation analyses. The results supported our model. This study takes an important step toward elucidating the role of mobile technology in worklife conflict and technostress, and it illustrates the roles of perceived interruption overload as well as conflict and technostress in IT use.
