How It Feels to Be "Left on Read": Social Surveillance on Snapchat and Young Individuals' Mental Health

Research has shown that young individuals frequently turn to social networking sites (SNSs) to monitor others' behaviors. This is especially likely with Snapchat, as this platform offers extensive monitoring options in real time, for instance through the use of the "snap map". However, despite the growth of surveillance features, little is known about the use of these features and their possible association with individuals' mental health. Consequently, this cross-sectional survey among 16-to 25-year-olds (N = 360, Mage = 19.51) examines (1) whether individuals with a higher need for popularity are more likely to engage in Snapchat surveillance behaviors, (2) whether these behaviors, in turn, are associated with indicators of individuals' mental health, specifically feelings of loneliness and depressive symptoms, and (3) whether fear of missing out mediates the association between surveillance behaviors and these mental health indicators. The findings show that a higher need for popularity is associated with the monitoring of others through Snapchat, which, in turn, was associated with health indicators via fear of missing out. These associations were, however, not found for general Snapchat use, indicating that specific uses of this platform are more detrimental than others. Future research should, therefore, focus more thoroughly on the relationships between specific SNS behaviors and individuals' mental health.
