THE LONGITUDINAL ASSOCIATION BETWEEN PASSIVE SOCIAL NETWORKING SITE USAGE AND DEPRESSIVE SYMPTOMS: THE MEDIATING ROLE OF ENVY AND MODERATING ROLE OF LIFE SATISFACTION

Introduction: The relationship between Social Networking Site (SNS) usage and depressive symptoms is a growing concern among mental health researchers and practitioners. The purpose of this study was to better understand the mechanism and context under which SNS use affects depressive symptoms. Method: We did this by examining envy as a mediator of the relationship between passive SNS usage and depression over time, with life satisfaction as a moderator of this mediation effect. The sample included 266 college students, who completed the surveys in two waves. Results: The results showed that envy fully mediated the association between passive SNS usage and depression. This indirect relationship was moderated by level of life satisfaction. Specifically, and unexpectedly, among individuals with higher levels of life satisfaction, more frequent passive SNS use was related to increased envy, which, in turn, was associated with increased depressive symptoms. However, this indirect relationship was non-significant for those with lower levels of life satisfaction. Discussion: Thus, the potential of passive SNS use to increase depressive symptoms through envy among individuals with high life satisfaction should be considered when mental health practitioners design interventions.
