The chain mediating effect of self-respect and self-control on peer relationship and early adolescent phone dependence.

This paper analyzes the influence of peer relationship on mobile phone dependence of middle school students, and probes into the chain mediating role of Self-respect and self-control. Using multi-stage random stratified cluster sampling method, 2311 middle school students in Wuling Mountain District were selected to explore the relationship between peer relationship and mobile phone dependence, Self-respect and self-control by using peer relationship scale, mobile phone dependence Scale, Self-respect scale and self-control scale. Correlation analysis showed that peer relationship, Peer relationship was positively correlated with Self-respect and self-control (r = 0.399, r = 0.291, P < 0.01), while peer relationship was negatively correlated with mobile phone dependence (r=- 0.227, P < 0.01). Mobile phone dependence was negatively correlated with Self-respect and self-control (r=- 0.409, r=- 0.629, P < 0.01). Self-respect was positively correlated with self-control (r = 0.519, P < 0.01). The structural equation model shows that Self-respect and self-control play a partial mediating role in the relationship between peer relationship and mobile phone dependence, in which the mediating effect size of Self-respect is - 0.098 (effect size 18.63%, 95%CI=- 0.140- 0.059), and the mediating effect size of self-control is - 0.131 (effect size 24.90%, 95%CI=- 0.188- 0.073); The chain mediating effect size of Self-respect and self-control was - 0.252 (effect size 47.91%, 95%CI = - 0.293~- 0.434). We should actively intervene the problem of mobile phone dependence of middle school students, improve Self-respect and self-control ability through good peer relationship, effectively improve their health behavior, and promote mental health.
