The relationship between narcissism, intensity of Facebook use, Facebook flow and Facebook addiction.

Introduction: The present study investigated mechanisms that may contribute to the enhanced risk of narcissistic individuals to develop Facebook addiction.

Methods: In a sample of 449 Facebook users (age: () = 31.07(9.52), range: 18-65) the personality trait narcissism, Facebook flow, intensity of Facebook use, and Facebook addiction were assessed by an online survey.

Results: In a moderated mediation analysis, the positive relationship between narcissism and Facebook addiction was positively mediated by the level of flow experienced on Facebook. Intensity of Facebook use moderated the positive association between Facebook flow and Facebook addiction.

Conclusions: Excessive Facebook use may cause psychological dependence. Narcissistic individuals are at enhanced risk for this form of dependence that is fostered by experience of flow during Facebook use and intensity of Facebook use. Current results should be taken into account, when assessing individuals at risk for pathological Facebook use and when planning specific interventions to deal with it.
