新的研究表明，情绪处理困难反映了共同发生的述情障碍，而不是自闭症谱系障碍（ASD）的核心特征。因此，有述情障碍的自闭症患者可能代表了一个特定的自闭症亚群，他们可能会从量身定制的干预措施中受益。本系统综述和荟萃分析的目的是使用多伦多述情障碍量表（TAS）探讨自闭症述情障碍的性质和患病率。使用TAS系统检索在线科学数据库中关于ASD人群的研究。进行荟萃分析，以评估ASD和神经型组之间的评分差异，并确定这些人群中述情障碍的患病率。确定了15篇比较自闭症和神经型（NT）组的文章。与NT组相比，自闭症患者在所有分数上的得分都显着更高。ASD组的述情障碍患病率也较高（49.93%对4.89%），自闭症参与者的述情障碍风险显著增加。这篇综述强调了述情障碍在ASD中是常见的，而不是普遍的，支持越来越多的证据表明，自闭症和述情障碍并存代表了ASD人群中可能具有特定临床需求的特定亚组。需要更多的研究来了解共同发生的ASD和述情障碍的性质和影响。
New research suggests that, rather than representing a core feature of autism spectrum disorder (ASD), emotional processing difficulties reflect co-occurring alexithymia. Autistic individuals with alexithymia could therefore represent a specific subgroup of autism who may benefit from tailored interventions. The aim of this systematic review and meta-analysis was to explore the nature and prevalence of alexithymia in autism using the Toronto Alexithymia Scale (TAS). Online scientific databases were searched systematically for studies on ASD popu lations using the TAS. Meta-analyses were performed to evaluate differences in scores between the ASD and neurotypical groups, and to determine the prevalence of alexithymia in these populations. 15 articles comparing autistic and neurotypical (NT) groups were identified. Autistic people scored significantly higher on all scores compared to the NT group. There was also a higher prevalence of alexithymia in the ASD group (49.93% compared to 4.89%), with a significantly increased risk of alexithymia in autistic participants. This review highlights that alexithymia is common, rather than universal, in ASD, supporting a growing body of evidence that co-occurring autism and alexithymia represents a specific subgroup in the ASD population that may have specific clinical needs. More research is needed to understand the nature and implications of co-occurring ASD and alexithymia.
