摘要

The present study aimed to explore the mediating role of poor academic achievement and the moderating role of cumulative lifestyle risk factors (CLRF) in the relationship between mobile phone addiction and depression. In the cross-sectional study, a sample of 21,481 adolescents (mean age = 15.42 years, SD = 1.79) were recruited through a multi-stage cluster sampling method. Information was collected on demographic characteristics, Problematic Mobile Phone Use (PMPU), academic achievement, CLRF, and depressive symptoms. Mediation and moderation analyses were performed with the PROCESS macro v3.4 for SPSS. The results found that PMPU was significantly and positively associated with depressive symptoms, and the association was found to be mediated by poor academic achievement. In addition, CLRF moderated the pathways from PMPU to depressive symptoms. The present study enhances our understanding of how and under what conditions PMPU affects depressive symptoms. Practitioners should pay more attention to students with poor academic achievement and provide them with help and encouragement to reduce their depressive symptoms. Moreover, a variety of healthy lifestyle practices can be incorporated as a supplement in intervention programs to reduce depressive symptoms in adolescents.
