Objectives: This study aimed to examine the influence of academic engagement and grit on the relationship between parental structure provision and academic achievement. Specifically, this research sought to verify the moderated mediating effect of grit on the relationship between parental structure provision and academic achievement through academic engagement of children. Methods: The research subjects were 2,522 Children from the Korean Child and Youth Panel Survey 2018 panel (the first-year survey) by National Youth Policy Institute. Participants completed selfreport questionnaires designed to assess parental structure provision, academic engagement, grit, and academic achievement. Data were analyzed for moderated mediating effects between variables using PROCESS macro version 3.0 (Model 1, 4, 14) methods. Results: First, the mediating effect of academic achievement on the process of parental structure provision was proved to affect academic achievement. Second, as for the effects of academic engagement on academic achievement, the adjustment effect was found to vary according to the level of grit. Finally, the moderated mediating effect of grit was verified. Namely, the mediating effect of academic achievement was moderated by grit in the relationship between parental structure provision and academic achievement. The indirect effect of academic engagement was that the lower the level of grit, the higher the level of academic achievement.
Conclusion:This study is meaningful in providing academic information that emphasizes the importance of parental structure provision and academic engagement by confirming that it is a protective factor for grit. The results of this study provide academic data for the development of intervention programs to improve children's academic achievement.
