Abstract

Background: This study investigated the presence and level of alexithymia and examined the relationship between alexithymia and affect recognition abilities after acquired brain injury (ABI), accounting separately for etiology due to stroke or traumatic brain injury (TBI).

Methods: Ninety-nine neurologically healthy adults (NHA) and 119 adults with moderate-to-severe ABI (63 TBI, 56 stroke) participated. Main measures included the Toronto Alexithymia Scale-20 (TAS-20) and Multicultural Facial Emotion Perception Test (MFEPT).

Results: ABI groups endorsed greater alexithymia than NHA, but TBI and stroke subgroups did not significantly differ. Hierarchical multiple regression indicated that TAS-20 subscales difficulty identifying feelings (DIF) and externally oriented thinking (EOT), but not Difficulty Describing Feelings (DDF), added unique value to predicting objective affect recognition (MFEPT) after accounting for age, education, sex, face recognition ability, and general cognitive function. Moreover, the relationship between alexithymia and affect recognition was moderated by group: DIF and DDF were inversely related to MFEPT only for adults with ABI. EOT was inversely related to affect recognition for all three groups.

Conclusions: Adults with ABI experience alexithymia more frequently and intensely than neurologically healthy adults, and this impairment may partly underlie struggles with affective processing frequently observed in these individuals on experimental tasks and in real-world interactions.

述情障碍预测后发性脑损伤后的面部情绪知觉。

背景：本研究调查了获得性脑损伤（ABI）后述情障碍的存在和水平，并探讨了述情障碍与情感识别能力的关系，分别考虑了脑卒中或创伤性脑损伤（TBI）所致的病因。方法：99例神经系统健康成人（NHA）和119例中重度ABI成人（TBI 63例，卒中56例）参与研究。主要测量方法包括多伦多述情障碍量表20 （TAS-20）和多元文化面部情绪知觉测验（MFEPT）。结果：ABI组比NHA组支持更大的述情障碍，但TBI和卒中亚组无显著差异。分层多元回归结果表明，TAS-20量表在考虑年龄、教育程度、性别、面部识别能力和一般认知功能等因素后，对客观情感识别（MFEPT）具有独特的预测价值，而对情感描述困难（DDF）的预测价值不显著。此外，述情障碍与情感识别之间的关系被组调节：仅在ABI成人中，DIF和DDF与MFEPT呈负相关。EOT与三组情感认知呈负相关。结论：ABI患者比神经系统健康的成年人更频繁、更强烈地经历述情障碍，这种损伤可能在一定程度上是这些个体在实验任务和现实世界互动中经常观察到的情感处理斗争的基础。
