METHODS
Data were collected from 324 middle school students in D City during the period of July 1st-17th, 2015. Multiple regression analysis, the Baron & Kenny's mediation verification, and Sobel test were conducted to measure the mediating effects of self-esteem and resilience on depression.
RESULTS
There were significant correlations among the variables; smartphone addiction, self-esteem, resilience, and depression. Self-esteem had a complete mediating effect(β=-.40, p<.001) in the relationship between smartphone addiction and depression(Sobel test: Z=4.68, p<.001). Resilience had a partial mediating effect(β=-.15, p<.001) in the relationship between smartphone addiction and depression(Sobel test: Z=2.40, p<.001).
