Psychopathological symptoms and social networking sites addiction in Poland and Germany: The role of fear of missing out and preference for online social interaction

Psychopathological symptoms, especially depression and anxiety, can contribute to the development of addictive tendencies offline and online. The present cross-national study aims to verify whether Fear of Missing Out (FoMO) and Preference for Online Social Interactions (POSI) could explain the relationship between psychopathological symptoms (i.e., depression and anxiety symptoms) and Social Networking Sites (SNS) addiction. We tested our hypothesis in two samples from Poland (N = 1163) and Germany (N = 781) using self-report measures of psychopathological symptoms, FoMO, POSI, and SNS addiction. In both countries, we found the same result pattern. Depression and anxiety symptoms were positively related to SNS addiction. Moreover, FoMO and POSI partially mediated the relationship between psychopathological symptoms and addictive SNS use. Notably, the relationship between psychopathological symptoms is significantly more robust via FoMO as it is an essential predictor of SNS addiction in both countries. Our findings show that ineffective emotional regulation, as well as maladaptive thoughts and beliefs about one's Internet use among persons with psychopathological symptoms, might increase the risk for SNS addiction.
