摘要

Adolescents with social anxiety are at elevated risk for problematic mobile phone use (PMPU), yet the developmental processes underlying this association remain unclear. This study aims to examine the pathway from rumination to depression and investigate whether this pathway mediates the association between social anxiety and PMPU. Data were collected from 287 Chinese adolescents (194 females, mean age = 16.34 years, SD = 0.81, ages 15–18) via a two-wave longitudinal survey with a six-month interval. Adolescents completed measures of social anxiety and rumination at baseline and depressive symptoms and PMPU six months later. Mediation analyses using the PROCESS macro Model 6 indicated that social anxiety predicted adolescent PMPU over time, with depressive symptoms serving as a significant mediator. Moreover, a sequential pathway from rumination to depressive symptoms further explained how social anxiety contributed to later PMPU, whereas rumination alone was not a significant mediator. These findings highlight the significant role of the rumination-depression pathway in the long-term effects of social anxiety on adolescent PMPU. Based on these results, interrupting the development of depression triggered by rumination emerges as a valuable approach to alleviating the adverse effects of social anxiety on adolescent PMPU.
