The Influence of Physical Self-Image on Adolescents’ Depression : The Dual Mediating Roles of Peer Attachment and Self-Esteem

This study aimed to explore how peer attachment and self-esteem mediate the association between adolescents’ physical self-image and their levels of depression. The sample consisted of 1,328 middle school students who participated in the 14th wave of the Korean Children and Youth Panel Survey (KCYPS). Descriptive statistics, correlation analysis, and significance analysis of mediating pathways were conducted using SPSS 26.0. and the SPSS PROCESS macro 3.3. The results were as follows: First, a significant mediating effect of peer attachment was confirmed in the relationship between physical self-image and depression. Second, a significant mediating effect of self-esteem was also confirmed in the relationship between physical self-image and depression. Finally, both peer attachment and self-esteem demonstrated a significant dual mediating effect on the relationship between physical self-image and depression. This study suggests that an integrative approach is necessary for effectively preventing and inventing in adolescents’ depression, one that enhances not only physical self-image but also peer attachment and self-esteem.
