Abstract

Background
This study aimed to determine the mediating role of loneliness in the relationship between anxiety and smartphone overdependence among Korean adolescents.
Methods
This national cross-sectional secondary study used data from the 16th (2020) Korea Youth Risk Behavior Survey. The sample comprised 54,948 adolescents in middle and high schools. The mediating effects were analyzed using the procedure of Baron and Kenny and the Sobel test.
Results
Anxiety impacted both loneliness and smartphone overdependence (P<0.001). Additionally, loneliness was identified as a factor influencing smartphone overdependence (P<0.001). Loneliness demonstrated a statistically significant mediating effect in the relationship between anxiety and smartphone overdependence (P<0.001).
Conclusions
It was concluded that smartphone overdependence increases with the heightened maladaptive emotions of adolescents, such as anxiety and loneliness. These findings confirmed the mediating role of loneliness in the relationship between anxiety and smartphone overdependence.
