针对多伦多述情障碍自陈量表（TAS）的不足，进行了两项研究，以重建规模的项目域。第一项研究导致了一个新的20项版本的量表TAS-20的发展。TAS-20表现出良好的内部一致性和重测信度，三因素结构理论上与述情障碍结构一致。在第二项研究中，通过使用验证性因子分析，证明了这三个因素结构的稳定性和可重复性。
Addressing shortcomings of the self-report Toronto Alexithymia Scale (TAS), two studies were conducted to reconstruct the item domain of the scale. The first study resulted in the development of a new twenty-item version of the scale-the TAS-20. The TAS-20 demonstrated good internal consistency and test-retest reliability, and a three-factor structure theoretically congruent with the alexithymia construct. The stability and replicability of this three-factor structure were demonstrated in the second study with both clinical and nonclinical populations by the use of confirmatory factor analysis.
