Fear of Missing Out (FoMO) is a feeling of fear of missing out on a precious moment about another individual or group in which that person cannot be present and is characterized by a desire to stay connected to what others are doing via the internet or social networks. So there is a need for research to measure the effect of Fear of Missing Out (FoMO), and how these influences affect FoMO, so that a theoretical model can be constructed.This study aims to explain the model of the influences that affect FoMO through self-regulation as a moderating variable. The research method uses quantitative methods. The data analysis technique used in this study is the structural equation model (SEM). The tool used to implement this analysis technique is the AMOS program. The results showed that the research model was stated in accordance with the data (goodness of fit). With the results of a significance level of 5%, it proves that self-regulation is able to mediate the relationship between the influence of social networks on FoMO
