OBJECTIVE
The 20-item Toronto Alexithymia Scale (TAS-20) measures three intercorrelated dimensions of alexithymia: (1) difficulties identifying feelings (DIF), (2) difficulties describing feelings (DDF), and (3) externally oriented thinking (EOT). The aim of the study was to test the three-factor model of the TAS-20 using confirmatory factorial analyses (CFA).
METHOD
769 healthy subjects and 659 patients meeting the DSM-IV criteria for substance use disorders or eating disorders completed the TAS-20. The correlation matrices for each of the samples were analyzed with LISREL 7.16.
RESULTS
In each sample, the three-factor model was found to be replicable.
CONCLUSION
The three TAS-20 subcales can be used to explore the distinct facets of the alexithymia construct.
目的
20项多伦多述情障碍量表（TAS - 20）测量述情障碍的三个相互关联的维度：（1）识别情感困难（DIF），（2）描述情感困难（DDF），以及（3）外向性思维（EOT）。本研究的目的是使用验证性因素分析（CFA）来检验TAS - 20的三因素模型。
方法
769名健康受试者和659名符合物质使用障碍或饮食障碍DSM - IV标准的患者完成了TAS - 20。使用LISREL 7.16分析每个样本的相关矩阵。
结果
在每个样本中，三因素模型被发现是可重复的。
结论
TAS - 20的三个子量表可用于探索述情障碍结构的不同方面。
