How Does Parental Smartphone Addiction Affect Adolescent Smartphone Addiction? Testing the Mediating Roles of Parental Rejection and Adolescent Depression

Little has been known about the mechanisms underlying parental smartphone addiction (PSA) and adolescent smartphone addiction (ASA). This study examined whether PSA predicts ASA and investigated the mediating roles of parental rejection (PR) and adolescent depression (ADP) among a sample of 4,415 parent-child dyads. Analysis of a serial multiple-mediator model indicated that PSA positively predicted ASA (B = 0.13, SE = 0.02, 95% confidence interval [CI] = 0.09-0.16). In addition, PR and ADP sequentially mediated the link between PSA and ASA (B = 0.01, 95% boot CI = 0.01-0.02). Implications of the findings and directions for future research are discussed.
