Online Social Network Site Addiction: A Comprehensive Review

Research into online social network site (SNS) addiction (i.e., excessive and compulsive online social networking) has expanded over the last years. This paper aims to give a review of this research. Although not formally recognized as a diagnosis, SNS addiction shares many similarities with those of other addictions, including tolerance, withdrawal, conflict, salience, relapse, and mood modification. Several screening instruments to identify SNS addicts have been developed—approaching the phenomenon in various ways, disclosing a conceptual and empirical obscurity in this field. Theoretical and empirical models suggest that SNS addiction is molded by several factors; including dispositional, sociocultural, and behavioral reinforcement. Also, empirical findings generally unveil that SNS addiction is related to impaired health and well-being. There has been little, if any, empirical testing of prevention or treatment for this behavioral addiction, although certain self-help strategies, therapies, and interventions have been proposed. © 2015, Springer International Publishing AG.
