This study investigated the mediating effects of sleep duration and quality on the relationships between adolescents’ smartphone addiction tendencies and depressive symptoms. We performed multiple mediation analysis with Hayes’ Process Macro program and bootstrapping. A survey was conducted with 410 high school students and the following tools were used; a smartphone addiction scale(S-scale), a questionnaire on sleep duration, the PSQI-K, and the CES-D. The data thus collected were analyzed by SPSS 22.0 and Process Macro. The results were as follows: First, adolescents’ smartphone addiction tendencies did not affect depressive symptoms through sleep duration. Second, adolescents’ smartphone addiction tendencies significantly influenced depressive symptoms through sleep quality. This study provides initial evidence suggesting the importance of sleep quality rather than sleep duration in the relationship between adolescents’ smartphone addiction tendencies and depressive symptoms.
