During adolescence, experiences of stress tend to increase due to individual, social and scholastic changes and challenges which pose a risk for students’ academic development. However, effort and interest may function as protective factors within the relationship of stress and academic grades. Specifically, in this study it is explored whether different aspects of stress – namely, ability to cope and helplessness – influence grit (interest and effort), and if grit explains the association between stress and academic grades. A total of N = 733 6th to 8th graders participated in a survey. The results from Structural Equation Modeling showed that ability to cope had a positive effect on effort, while helplessness had a negative effect on interest. Finally, grit mediated the relationship between stress and academic grades. Theoretical and practical implications are discussed to prevent negative effects of stress on students’ academic development.

在青春期，由于对学生的学业发展构成风险的个人、社会和学业变化和挑战，压力体验往往会增加。然而，努力和兴趣可能在压力和学业成绩的关系中起到保护因素的作用。具体来说，在这项研究中，探讨了压力的不同方面——即应对能力和无助感——是否会影响毅力（兴趣和努力），以及毅力是否可以解释压力与学业成绩之间的关联。共N个 = 733 名 6 至 8 年级学生参与了一项调查。结构方程模型的结果表明，应对能力对努力有积极影响，而无助感对兴趣有负面影响。最后，毅力调节了压力与学业成绩之间的关系。讨论了理论和实践意义，以防止压力对学生的学业发展产生负面影响。
