摘要

This study aimed to examine the association between childhood trauma and mobile phone dependency among adolescents, as well as the mediating roles of self-esteem and depressive symptoms in this association. A questionnaire survey was conducted among 3,866 middle school students from Guizhou Province, using the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Self-Esteem Scale (SES), the Patient Health Questionnaire-9 (PHQ-9), and the Mobile Phone Addiction Index (MPAI). The results showed: (1) Childhood trauma positively predicted mobile phone dependency in adolescents (β = 0.55, p < 0.001); (2) Self-esteem (β = 0.05, p < 0.001) and depressive symptoms (β = 0.17, p < 0.001) each played a partial mediating role in the relationship between childhood trauma and mobile phone dependency, accounting for 9.10% and 30.91% of the total effect, respectively; (3) Childhood trauma also indirectly influenced mobile phone dependency through a chain-mediating effect composed of self-esteem and depressive symptoms (β = 0.15, p < 0.001), with an indirect impact accounting for 27.27% of the total. Childhood trauma is not only a significant external factor influencing mobile phone dependency among adolescents but also exerts an indirect effect on such dependency by impacting adolescents’ self-esteem and depressive symptoms levels.
