Relationship between Materialism and Social Networking Site Addiction among Adolescents: A Moderated Mediation Model

Abstract

Materialism has been consistently linked to Internet-related addictions, including compulsive online shopping, problematic online gaming, and excessive smartphone use; however, the relationship between materialism and social networking site (SNS) addiction has remained unclear. Thus, this study aims to examine the association between materialism and SNS addiction and investigate the mediating effect of fatalism and moderating effect of self-concept clarity in this relationship among 703 Chinese adolescents. Materialism was significantly positively associated with SNS addiction in adolescents, and fatalism partially mediated this association. Moreover, self-concept clarity moderated the direct and indirect relationships between materialism and SNS addiction. Specifically, for adolescents with low (versus high) self-concept clarity, those who also had high levels of materialism were more likely to develop fatalistic beliefs and showed further symptoms of SNS addiction. This study’s findings imply that decreasing materialism and fatalism and developing self-concept clarity might be effective interventions for reducing SNS addiction among adolescents.
