述情结构通常采用20项多伦多述情量表（TAS-20）进行测量，该量表有20多种不同的语言翻译。然而，尽管复制了因素结构，但不能假设观察到的TAS-20平均分数的差异可以在不同的语言和文化群体中得到类似的解释。还需要演示语言的测量不变性（MI）。本研究的目的是利用17866名加拿大新兵的数据来评估英语和法语版本的TAS-20的MI；71%的人以英语为母语，29%的人以法语为母语。我们使用验证性因子分析（CFAs）建立了TAS-20的基线模型，并使用四个限制性越来越强的多组CFA分析来评估MI的结构、度量、标量和剩余误差水平。两个样本中最适合的因子结构是一个倾斜的3因子模型，其中包含一个由负关键项组成的附加方法因子。MI在所有四个不变性级别上都实现了。两个样本的平均得分只有很小的差异。结果支持英语和法语版本的TAS-20的MI，允许对加拿大法语和英语群体的调查结果进行有意义的比较。
The alexithymia construct is commonly measured with the 20-Item Toronto Alexithymia Scale (TAS-20), with more than 20 different language translations. Despite replication of the factor structure, however, it cannot be assumed that observed differences in mean TAS-20 scores can be interpreted similarly across different languages and cultural groups. It is necessary to also demonstrate measurement invariance (MI) for language. The aim of this study was to evaluate MI of the English and French versions of the TAS-20 using data from 17,866 Canadian military recruits; 71% spoke English and 29% spoke French as their first language. We used confirmatory factor analyses (CFAs) to establish a baseline model of the TAS-20, and four increasingly restrictive multigroup CFA analyses to evaluate configural, metric, scalar, and residual error levels of MI. The best fitting factor structure in both samples was an oblique 3-factor model with an additional method factor comprised of negatively-keyed items. MI was achieved at all four levels of invariance. There were only small differences in mean scores across the two samples. Results support MI of English and French versions of the TAS-20, allowing meaningful comparisons of findings from investigations in Canadian French-speaking and English-speaking groups.
