This study is a conceptual replication of Teimouri et al.'s (2022) investigation into the validity of the second language (L2) grit scale (the L2-Grit scale). There are several concerns about the generalizability of the findings of Teimouri et al. (2022), especially regarding the discriminant validity of the scale and the relation of L2 grit with language achievements. A conceptual replication study was conducted because these concerns could be addressed by using a different methodology. The main findings include: (a) the factor structure of L2 grit was supported in the replication sample (106 English majors at a Japanese university), (b) the results support the discriminant validity of L2 grit, but in a different way from the initial study, and (c) L2 grit was a consistent predictor of L2-specific Grade Point Average and standardized test score. The results obtained lend further support for the validity of the L2-Grit scale.

这项研究是 Teimouri 等人 (2022) 对第二语言 (L2) 毅力量表（L2-Grit 量表）有效性调查的概念复制。对于 Teimouri 等人的研究结果的普遍性存在一些担忧。 (2022)，特别是关于量表的判别有效性以及第二语言毅力与语言成绩的关系。进行了概念复制研究，因为这些问题可以通过使用不同的方法来解决。主要发现包括：(a) L2 毅力的因子结构在复制样本（日本大学的 106 名英语专业学生）中得到支持，(b) 结果支持 L2 毅力的判别有效性，但方式与(c) L2 毅力是 L2 特定平均绩点和标准化考试成绩的一致预测因子。获得的结果进一步支持了 L2-Grit 量表的有效性。
