The purpose of this study was to examine the effects of peer attachment and parental abuse on adolescents' dependence on mobile phones and the mediating effect of self-esteem. For this study, I used the panel data of the 7th year of the 1st grade of the elementary school for the Korean Children and Youth Panel Survey provided by the Korea Youth Policy Institute. A total of 1,937 adolescents were selected to analyze causal relationship among variables, and SPSS 26.0 and AMOS 26.0 were used to verify research problem. As a result of the study, First, the better the relationship with peers, the higher the self-esteem and the less the dependence on their mobile phone. On the other hand, the more severe the abuse, the lower the self-esteem and the higher the dependence on mobile phones.
Second, Self-esteem was found to have a significant effect on peer attachment and abuse on mobile phone dependence. Based on these results, I would like to provide them as basic data for helping positive development of adolescents.
