Abstract

This study compared the 20-item revised Toronto Alexithymia Scale with the 26-item version for 257 psychiatric outpatients. Scores on the 20-item version significantly correlated with those on the 26-item inventory even when controlled for depressed mood. Furthermore, the 20-item scale showed greater internal consistency. Factor analysis for both versions indicated three subfactors but the factors in the TAS-20 accounted for greater common variance (92%) than for the factors in the TAS-26 (78%). The total variance accounted for by these factors on the TAS-20 (45%) was also greater than for the TAS-26 (38%).

摘要

本研究对257名精神科门诊患者使用20项修订版多伦多述情障碍量表与26项版本进行了比较。即便在控制了抑郁情绪的情况下，20项版本的得分与26项量表的得分仍显著相关。此外，20项量表显示出更高的内部一致性。两个版本的因子分析均表明存在三个子因子，但多伦多述情障碍量表20项版本（TAS-20）中的因子所解释的共同方差（92%）高于多伦多述情障碍量表26项版本（TAS-26）中的因子（78%）。TAS-20中这些因子所解释的总方差（45%）也高于TAS-26（38%）。
