Abstract

Introduction: This study examined how lifestyle risk behaviors mediate the relationship between smartphone overdependence, depressive symptoms, and suicidal behavior in adolescents. Method: Based on a secondary analysis of national survey data obtained in 2020 in South Korea, this study had 54,948 participating adolescents. Multiple logistic regression and mediating effect analyses were used to assess the relationships between the study variables. Results: Adolescents’ lifestyle risk behaviors partially mediated the link between smartphone overdependence and depression (Z = 6.86, p < .001), suicidal ideation (Z = 7.04, p < .001), and suicidal planning (Z = 4.59, p < .001). Discussion: This is the first study to examine the mediating role of comprehensive lifestyle behaviors, not single habits, in the relationship between smartphone overdependence, depression, and suicidal behaviors. Encouraging healthy lifestyle behaviors in adolescents can help alleviate the link between smartphone overdependence and mental health problems.
