Alexithymia can be defined as inability to identify and describe emotions in the self. Has shown to be related to several psychological and pathological processes that can result in unsatisfactory interpersonal relationships and decreased social adjustment. Advances in research of alexithymia require the development and validation of assessment instruments, and its application to different population. With this aim, we studied the psychometric properties of the Twenty-Item Toronto Alexithymia Scale (TAS-20) in Chilean population using various modeling procedures (e.g., CFA, ESEM) in different structures (i.e., Correlated, Unidimensional, Hierarchical or Wording factors). Among the 10 models tested, the four-dimensional structure offered the best fit but with item-loading problems in the last factor (Pragmatic Thinking). We suggest that the studied version of the scale needs improvement (theoretical and empirical) to ensure optimal indices of validation for Chilean population.
述情障碍可被定义为无法识别和描述自身的情绪。研究表明，它与多种心理和病理过程相关，这些过程可能导致人际关系不尽人意以及社会适应能力下降。述情障碍研究的进展需要开发和验证评估工具，并将其应用于不同人群。出于这一目的，我们使用不同结构（即相关、单维、层次或措辞因素）中的各种建模程序（例如，验证性因素分析、扩展的验证性因素分析），研究了智利人群中20项多伦多述情障碍量表（TAS-20）的心理测量特性。在测试的10个模型中，四维结构提供了最佳拟合，但最后一个因素（实用思维）存在项目负荷问题。我们建议，该量表的研究版本需要（从理论和实证方面）改进，以确保针对智利人群的最佳验证指标。
