OBJECTIVE
Temporal stability is a basic assumption underlying any personality trait construct. Previous research on the stability of alexithymia has led to a controversy over whether alexithymia should be viewed as a state-dependent phenomenon or as a stable personality trait. The aim of this 5-year longitudinal study was to examine the temporal stability of alexithymia in the general population in Finland.
METHODS
Alexithymia was measured with the 20-Item Toronto Alexithymia Scale (TAS-20) at the baseline and 5 years later.
RESULTS
The test-retest correlations of the TAS-20 total and factor-specific scores at the baseline and at the 5-year follow-up ranged from moderate to high in both genders, reflecting a rather high relative stability of the TAS-20 scores over a period of 5 years.
CONCLUSIONS
The findings of our study suggest that alexithymia behaves like a stable personality trait in the general population.
目的
时间稳定性是任何人格特质结构的一个基本假设。先前关于述情障碍稳定性的研究引发了一场争议，即述情障碍应被视为一种依赖状态的现象还是一种稳定的人格特质。这项为期5年的纵向研究的目的是检验芬兰普通人群中述情障碍的时间稳定性。
方法
在基线时和5年后使用20项多伦多述情障碍量表（TAS-20）对述情障碍进行测量。
结果
TAS-20总分及各因子得分在基线和5年随访时的重测相关性在两性中均从中度到高度不等，反映出TAS-20得分在5年期间具有相当高的相对稳定性。
结论
我们的研究结果表明，在普通人群中，述情障碍表现得像一种稳定的人格特质。
