This study investigated the effects of growth mindset and self-efficacy on foreign language achievement (FLA) in a sample of 379 intermediate learners of English as a foreign language (EFL) while also incorporating the mediation of second language (L2) grit in a structural model. The measurement model was examined using confirmatory factor analysis, and mediation analysis was conducted following Baron and Kenny’s (1986) method to explore the mediating role of L2 grit in the relationship between growth mindset, self-efficacy, and FLA. The results revealed that both L2 grit and English self-efficacy directly predicted FLA. Moreover, the mediation analysis revealed that growth mindset influenced FLA indirectly through the mediating role of L2 grit. These findings suggest that fostering growth mindset and self-efficacy beliefs in language learners could enhance their FLA, and that the development of L2 grit may play a significant role in mediating the relationship between growth mindset and FLA. Implications of these results for language education are discussed, and suggestions for future research are considered.

探索影响外语成绩的因素：成长心态、自我效能和第二语勇气的作用

本研究以 379 名英语作为外语 (EFL) 的中级学习者为样本，调查了成长心态和自我效能对外语成绩 (FLA) 的影响，同时还将第二语言 (L2) 勇气的中介作用纳入结构性研究中。模型。采用验证性因子分析对测量模型进行检验，并按照Baron和Kenny（1986）的方法进行中介分析，以探讨L2毅力在成长心态、自我效能和FLA之间关系中的中介作用。结果显示，L2 毅力和英语自我效能感直接预测 FLA。此外，中介分析显示，成长型思维通过 L2 毅力的中介作用间接影响 FLA。这些发现表明，培养语言学习者的成长心态和自我效能信念可以增强他们的 FLA，而二语毅力的发展可能在调节成长心态和 FLA 之间的关系中发挥重要作用。讨论了这些结果对语言教育的影响，并考虑了对未来研究的建议。
