摘要

背景人们认为童年和青少年时期的情感虐待与大脑有关;然而,这一认知过程的神经机制仍然未知。因此,我们旨在研究消极自动想法对青春期情感虐待与静息态功能连通性(rsFC)之间关系的中介作用。我们对54名13-17岁的青少年进行了社区样本统计分析,并进行了静息状态功能和结构磁共振成像(MRI)检查,同时使用自我报告量表对情感虐待和消极自动想法进行了评估。结果较高的消极自动想法与较低的连接性有关,而较高的情绪虐待程度则与较低的连接性有关(即抑制效应)。因此,情绪虐待与楔前皮层(pCun)-内侧前额叶皮层、海马旁皮层-外显皮层和颞皮层-颞极的连接性之间的关系因消极自动想法而降低。与此相反,当遭受情感虐待的青少年报告其有较高的消极自动想法倾向时,pCun-pCun、pCun-precuneus/后扣带回皮层和伏隔核-躯体运动区的功能连接则会受到强烈的介导。这些发现强调了创伤事件-神经系统的潜在认知处理过程,支持使用认知疗法治疗创伤后症状。

Emotional abuse mediated by negative automatic thoughts impacts functional connectivity during adolescence

Background

Emotional abuse during childhood and adolescence is thought to be associated with the brain; however, the neural mechanism underlying the cognitive process remains unknown. Therefore, we aimed to investigate the mediating effect of negative automatic thoughts on the relationship between emotional abuse and resting-state functional connectivity (rsFC) during adolescence.

Method

Our community sample included 54 adolescents aged 13–17 years in the statistical analysis. Resting-state functional and structural magnetic resonance imaging (MRI) was performed, while emotional abuse and negative automatic thoughts were assessed using self-reported scales. A mediation analysis was used to assess the contributions of early traumatic events and negative automatic thoughts to resting functional connectivity.

Result

Higher negative automatic thoughts were associated with lower connectivity in the context of greater emotional abuse (i.e., suppression effect). Thus, the relationships between emotional abuse and connectivity in the precuneus (pCun)-medial prefrontal cortex, parahippocampal cortex-extrastriate cortex, and temporal cortex-temporal pole were decreased by negative automatic thoughts. In contrast, functional connections in the pCun-pCun, pCun-precuneus/posterior cingulate cortex, and nucleus accumbens-somatomotor areas were strongly mediated when emotionally abused adolescents reported a high tendency for negative automatic thoughts.

Conclusion

Negative automatic thoughts strengthened the relationship between emotional abuse and rsFC. These findings highlight the underlying cognitive processing of the traumatic event-neural system, supporting the use of cognitive therapy for post-traumatic symptoms.

期刊介绍: Neurobiology of Stress is a multidisciplinary journal for the publication of original research and review articles on basic, translational and clinical research into stress and related disorders. It will focus on the impact of stress on the brain from cellular to behavioral functions and stress-related neuropsychiatric disorders (such as depression, trauma and anxiety). The translation of basic research findings into real-world applications will be a key aim of the journal. Basic, translational and clinical research on the following topics as they relate to stress will be covered: Molecular substrates and cell signaling, Genetics and epigenetics, Stress circuitry, Structural and physiological plasticity, Developmental Aspects, Laboratory models of stress, Neuroinflammation and pathology, Memory and Cognition, Motivational Processes, Fear and Anxiety, Stress-related neuropsychiatric disorders (including depression, PTSD, substance abuse), Neuropsychopharmacology.
