This study develops a theory-driven explanation for why individuals resume using SNS. The proposed IS return migration theory identifies novel two antecedents of SNS resumption: non-use-related dissatisfaction and use-related satisfaction. Also, we hypothesize dispositional resistance to change moderates the impact of non-use-related dissatisfaction and use related satisfaction on resumption. We conducted two studies to evaluate our model. Study One used the critical incident method to identify negative and positive antecedents to non-use related satisfaction and use-related satisfaction, thereby further developing the SNS resumption nomological net. Study Two extends these findings, using results of two three-wave surveys: one with recent ex-users who recently decided to stop using Facebook and one with long-standing ex-users who had stopped using Facebook months and years ago. Generally, we found support for our model, non-use related satisfaction and use-related satisfaction drove resumption intention and dispositional resistance moderated these relationships. Further, we found that time since quitting use moderated these relationships. Our findings advance understanding of resumption of SNS use, and understudied pattern of IT use and acceptance research. The paper concludes with a discussion of the implications of our findings for research and practice. Keywords: Social Network Sites, Resumption, Return Migration Theory, IT life cycle, Facebook
