The aim of this study was to examine the factor structure and the validity of the Finnish version of the 20-item Toronto Alexithymia Scale (TAS-20). As part of the Northern Finland 1966 Birth Cohort Project, the TAS-20 was presented to a sample of 5034 31-year old persons. A confirmatory factor analysis showed that the three-factor model, earlier established with the original TAS-20, was in agreement with the Finnish version of the scale. Three criteria of goodness-of-fit met the standards for adequacy of fit. For the total scale, internal reliability (Cronbach's alpha) was 0.83 and for the three subscales (factors 1, 2, and 3) it was 0.81, 0.77, and 0.66, respectively. Two- and one-factor models for TAS-20 were also examined, but the other models did not perform as well as the three-factor model. The factor model also worked well with a sample of 516 students with a mean age of 24.8 years. In conclusion, the TAS-20 scale is useful in the Finnish version, too.
本研究旨在检验20项多伦多述情障碍量表（TAS - 20）芬兰语版本的因子结构和效度。作为芬兰北部1966年出生队列项目的一部分，TAS - 20被应用于5034名31岁人群的样本。验证性因子分析表明，先前用原始TAS - 20建立的三因子模型与该量表的芬兰语版本相符。三个拟合优度标准均达到了拟合充分的标准。总量表的内部信度（克朗巴哈系数）为0.83，三个分量表（因子1、2和3）的内部信度分别为0.81、0.77和0.66。还检验了TAS - 20的二因子和单因子模型，但其他模型的表现不如三因子模型。该因子模型在一个平均年龄为24.8岁的516名学生样本中也运行良好。总之，TAS - 20量表的芬兰语版本也很有用。
