스마트폰 의존이 아동의 그릿을 매개로 학업성취에 미치는 영향 = The Mediating Role of Grit in the Relationship between Smartphone Dependency and Academic Achievement in Late School-Age Children

다국어 초록 (Multilingual Abstract)

This study aimed to examine the mediating role of grit in the relationship between smartphone dependency and academic achievement among late school-age children using a mediation model. The research subjects were 2,247 male and female children from the third year (2020) data of the Korean Children and Youth Panel Survey (KCYPS). Data analysis was conducted using SPSS 21.0 and AMOS 20.0 (IBM Co., Armonk, NY).
For the mediation effect analysis, a structural equation model was applied, and Sobel's test was performed using the multivariate delta method. The fit of the mediation model was evaluated based on the absolute fit index RMSEA and the relative fit indices TLI and CFI.
The results showed that as children's smartphone dependency increased, their level of grit decreased, which in turn influenced a decrease in academic achievement, demonstrating a significant mediating effect. In the mediation model, while the indirect effect was significant, the direct effect on academic achievement was not significant, indicating that the research model had a full mediation effect.
These findings suggest that increased smartphone dependency during the late school-age period leads to a decrease in internal attributes such as perseverance and tenacity. They also imply that grit plays an essential role in suppressing the negative effects of smartphone dependency while driving academic achievement.
The developmental importance of grit in suppressing the negative effects of smartphone dependency and its necessity for academic achievement was discussed, along with the meaning of grit as an essential personal attribute from a Christian perspective. Christian interventions and implications for promoting positive social achievement and inner strength in school-age children were also discussed.
