This study aims to examine the factor structure and validity of the Albanian TAS-20 (Toronto Alexithymia Scale) using a sample comprised of 342 students and 196 patients from a psychiatric clinic. Based on a literature review of studies of confirmatory factor analysis (CFA), three types of models were tested: first-order models with method factors and covariances, a second-order model with method factors and covariances, and nested models with method factors and covariances. The findings suggest that a three-factor correlated model with method factors was the best and most parsimonious solution for the clinical sample, exhibiting adequate levels of performance based on the goodness of fit criteria. However, regarding the student sample, the nested three-factor model with method factors and covariances demonstrated a superior fit when compared with the other tested models. Although the total scale of difficulty identifying feelings (DIF) and difficulty describing feelings (DDF) scores provided sound internal consistency, the externally oriented thinking (EOT) subscale did not. Nonetheless, as the CFA suggests the plausibility of negatively keyed items in the method factors, further interpretation of this scale is suggested. This study concludes that the TAS-20 of the Albanian language is appropriate for research purposes, and further research is needed for its application for clinical practice.

这项研究的目的是使用由342名学生和196名来自精神病诊所的患者组成的样本来检查阿尔巴尼亚TAS-20（多伦多Alexithymia量表）的因素结构和有效性。基于对确认性因子分析（CFA）研究的文献综述，测试了三种类型的模型：具有方法因子和协方差的一阶模型，具有方法因子和协方差的二阶模型以及具有方法因子和协方差的嵌套模型协方差。研究结果表明，具有方法因素的三因素关联模型是临床样品的最佳，最简约的解决方案，根据拟合标准的优劣表现出足够的性能水平。但是，关于学生样本，与其他测试模型相比，具有方法因子和协方差的嵌套三因子模型具有更高的拟合度。尽管识别感觉的困难（DIF）和描述感觉的困难（DDF）的总分表提供了良好的内部一致性，但面向外部的思维（EOT）子量表却没有。但是，由于CFA暗示了方法要素中负键项目的合理性，因此建议对该标准进行进一步解释。这项研究得出的结论是，阿尔巴尼亚语的TAS-20适用于研究目的，其在临床实践中的应用还需要进一步的研究。外部思考（EOT）量表没有。但是，由于CFA暗示了方法要素中负键项目的合理性，因此建议对该标准进行进一步解释。这项研究得出的结论是，阿尔巴尼亚语的TAS-20适用于研究目的，其在临床实践中的应用还需要进一步的研究。外部思考（EOT）量表没有。但是，由于CFA暗示了方法要素中负键项目的合理性，因此建议对该标准进行进一步解释。这项研究得出的结论是，阿尔巴尼亚语的TAS-20适用于研究目的，其在临床实践中的应用还需要进一步的研究。
