Construct validity of the 20-item Toronto Alexithymia Scale (TAS-20) was investigated by analyzing natural language use. It was hypothesized that the TAS-20 should be related to a lower use of emotion words and fewer references to social processes. 32 clinical interviews with mental health outpatients were analyzed with four categories of the computerized Linguistic Inquiry and Word Count dictionary: positive emotions, negative emotions, references to others, and communication words. The Difficulty Identifying Feelings subscale was positively related to negative emotion words, the Difficulty Describing Feelings subscale showed no relevant associations, and the Externally Oriented Thinking subscale was related to reduced use of positive emotion words and social process words. It is concluded that in this sample, the Externally Oriented Thinking subscale provides the best operationalization of the alexithymia construct.
通过分析自然语言的使用情况，对20项多伦多述情障碍量表（TAS - 20）的结构效度进行了研究。研究假设为，TAS - 20应与较少使用情感词汇以及较少提及社会过程相关。使用计算机化语言查询与字数统计词典的四类内容，对32名心理健康门诊患者的临床访谈进行了分析：积极情绪、消极情绪、对他人的提及以及交流词汇。难以识别情感分量表与消极情绪词汇呈正相关，难以描述情感分量表未显示出相关关联，而外向性思维分量表与积极情绪词汇和社会过程词汇的使用减少有关。研究得出结论，在该样本中，外向性思维分量表为述情障碍结构提供了最佳的操作化定义。
