초등학생의 운동시간과 스마트폰 의존도의 관계에서 그릿(grit)과 우울의 다중매개효과

초록

Purpose: This study aims to verify the multiple mediating effects of grit and depression on the relationship between exercise time and smartphone dependency in elementary school students. It emphasizes the need to enhance participation in physical activity to alleviate the increasing issue of smartphone overdependency. Methods: To achieve this, we utilized data from the third-year panel of Korean Children and Youth Panel Survey 2018 (KCYPS 2018) provided by the National Youth Policy Institute in Korea. A total of 2,364 participants (male: 1,179, female: 1,185) were included, and a multiple mediation model analysis was conducted. Results: The results revealed that elementary school students’ exercise time negatively predicted smartphone dependency, and there were significant indirect effects of grit and depression in the relationship between these two variables. Furthermore, the statistical significance of a sequential mediating model predicting smartphone dependence through exercise time, grit, and depression was confirmed. Conclusion: By increasing exercise time, it is possible to reduce elementary school students' dependency on smartphones, and such effects may also manifest indirectly through the elevation of grit or the reduction of depression. Additionally, the increased grit resulting from extended exercise time could contribute to lowering the level of depression, leading to an anticipated decrease in smartphone dependency among elementary school students.
