Instant messaging app use and depression among adolescents in South Korea: the roles of self-esteem and neuroticism

초록

Analyzing two-wave panel survey data from adolescents in South Korea, this study examined how instant messaging app use is associated with depression. Specifically, this study tested a moderated mediation model to determine between instant messaging app use and depression through self-esteem, and whether this pathway differs according to one's level of neuroticism. The results showed that instant messaging app use was positively associated with self-esteem, which was negatively related to depression. Furthermore, the indirect association between instant messaging app use and depression through self-esteem was stronger as adolescents' neuroticism level increased. These findings advance our understanding of the effect of instant messaging app use on depression among adolescents. The current study has important implications regarding the role of instant messaging app use in adolescents' psychological health.
