This study examined alternative methods for detecting alexithymia to the Toronto Alexithymia Scale-20 (TAS-20) by comparing the emotional linguistic performance of ASD and NT samples (n = 32 in each) on the Alexithymia Provoked Responses Questionnaire (APRQ). We utilised both the LIWC and tidytext approaches to linguistic analysis. The results indicate the ASD sample used significantly fewer affective words in response to emotionally stimulating scenarios and had less emotional granularity. Affective word use was correlated with ASD symptomatology but not with TAS-20 scores, suggesting that some elements of alexithymia are not well detected by the TAS-20 alone. The APRQ, in combination with the tidytext package, offers significant potential for sophisticated exploration of emotional expression in ASD.
本研究通过比较自闭症谱系障碍（ASD）和正常对照组（NT）样本对情绪诱发反应问卷（APRQ）的情感语言表现，检验了多伦多 20 项量表（TAS-20）以外的其他检测述情障碍的方法。我们利用 LIWC 和 tidytext 两种语言分析方法。结果表明，ASD 样本在对情绪刺激场景的反应中使用的情感词汇显著减少，情绪粒度也更低。情感词汇的使用与 ASD 症状相关，但与 TAS-20 评分无关，这表明 TAS-20 并不能很好地检测到述情障碍的某些方面。APRQ 结合 tidytext 包为深入探索 ASD 中的情感表达提供了巨大的潜力。
