尽管自闭症患者具有异质性,但社会情感障碍通常被认为是普遍存在的。然而,越来越多的证据表明,社交情感困难可能可以用述情障碍来解释,述情障碍是一种独特但经常共存的疾病。如果像一些人提出的那样,自闭症特征是导致社交情感障碍的原因,那么述情障碍本身可能是自闭症的一种症状。我们的目标是确定述情障碍是否应该被认为是自闭症的产物,还是应该被视为一种单独的疾病。使用因子分析和网络方法,我们提供了述情障碍和自闭症特征是不同的证据。我们认为:(1)自闭症的社会情绪处理模型应该将困难概念化为述情障碍的内在原因;(2)述情障碍的评估对于诊断和个性化干预至关重要。网上版载有补充材料,可在10.1007/s10803-021-05094-6查阅。
Despite the heterogeneity in autism, socioemotional difficulties are often framed as universal. Increasing evidence, however, suggests that socioemotional difficulties may be explained by alexithymia, a distinct yet frequently co-occurring condition. If, as some propose, autistic traits are responsible for socioemotional impairments, then alexithymia may itself be a symptom of autism. We aimed to determine whether alexithymia should be considered a product of autism or regarded as a separate condition. Using factor-analytic and network approaches, we provide evidence that alexithymic and autistic traits are distinct. We argue that: (1) models of socioemotional processing in autism should conceptualise difficulties as intrinsic to alexithymia; and (2) assessment of alexithymia is crucial for diagnosis and personalised interventions.
