The current study examined the longitudinal measurement invariance (LMI) of the Short Grit Scale (Grit-S) in a survey sample of Chinese young adults ( = 233, 48.9% male, mean age = 19.36 years, = 0.90 years) who completed the Grit-S twice over a 3-month interval. Confirmatory factor analysis was conducted to examine the LMI of the Grit-S across time. Results showed that the Grit-S has strict longitudinal invariance (i.e., equality of factor patterns, factor loadings, item intercepts, and item uniqueness for all items) over time. Additionally, the internal consistency indices of the Grit-S were acceptable across time, the stability coefficients over time were moderate, and latent factor means did not differ significantly across time. In sum, these findings suggest that the Grit-S has satisfactory longitudinal properties when used in Chinese young adults.
本研究在一个中国青年成年人调查样本（n = 233，48.9%为男性，平均年龄 = 19.36岁，标准差 = 0.90岁）中检验了简短坚毅量表（Grit-S）的纵向测量不变性，这些参与者在3个月的间隔内完成了两次Grit-S量表测试。进行验证性因素分析以检验Grit-S量表随时间的纵向测量不变性。结果显示，Grit-S量表在不同时间具有严格的纵向不变性（即所有项目的因素模式、因素载荷、项目截距和项目独特性均相等）。此外，Grit-S量表的内部一致性指标在不同时间均可接受，随时间的稳定性系数适中，潜在因素均值在不同时间无显著差异。总之，这些发现表明，Grit-S量表在中国青年成年人中使用时具有令人满意的纵向特性。
