This study was conducted to investigate the mediating effects of self-control in the relationship between preschooler's smartphone use and school readiness.
Data from the 7th wave of the Panel Study on Korean Children(N = 1,078). Mediating effect was analyzed using Structural Equation Modeling with Bootstrapping method utilizing SPSS 21.0 and AMOS 20.0.
Results showed that increased smartphone use has affected school readiness concerning social and emotional development, communication, approach to learning and cognitive development and general knowledge through self-control.
This indicates that while smartphone use itself does not directly affect school readiness, it seems to impede developing self-control; consequently, as self-control weakens, certain developmental domains for readiness to school may be hindered. This confirms that self-control plays an important mediating role between smartphone use and school readiness. Theoretical and practical implications, as well as limitations, are discussed.
Key Words: smartphone use, self-control, school readiness, mediating effects, bootstrapping method
