Studies on the psychometric properties of the EAS Temperament Survey (EAS) have produced equivocal results. In particular the psychometrics of the EAS are largely unknown in adolescence. Confirmatory factor analysis was used to explore the EAS structure in adolescents. Structural equation modeling was also used to assess measurement invariance and factor stability. A modified 4-factor model provided the best fit to the data and demonstrated reasonable longitudinal invariance and stability. Furthermore, the standardized factor scores correlated at near unity with the sum of observed scores, suggesting factor interpretations remained unchanged. However, the modifications suggest that further work is necessary.
对 EAS 气质调查（EAS）的心理测量学特性的研究产生了模棱两可的结果。特别是，EAS 的心理测量学在青春期还知之甚少。验证性因子分析用于探索青少年的 EAS 结构。结构方程模型也用于评估测量不变性和因子稳定性。经过修正的 4 因素模型与数据拟合最好，表现出合理的纵向不变性和稳定性。此外，标准化因子分数与观察分数的总和高度相关，表明因子解释保持不变。然而，这些修正表明需要进一步的工作。
