BACKGROUND
Exposure to stressful events related to the COVID-19 coronavirus pandemic has been associated with increases in the prevalence of depression and anxiety, raising questions about vulnerabilities that make some individuals more susceptible to internalizing symptoms following stress exposure.
METHODS
This prospective study examined the effects of neurophysiological reactivity to positive and threatening interpersonal stimuli, indexed by the late positive potential (LPP) event-related potential, in conjunction with exposure to interpersonal pandemic-related stressors in the prediction of internalizing symptom changes from before to during the pandemic. Emerging adults (n= 75) initially completed measures of internalizing symptoms and an interpersonal emotional images task while an electroencephalogram was recorded pre-pandemic and were recontacted during the COVID-19 pandemic in May 2020 to complete measures of exposure to pandemic-related stressful events and current internalizing symptoms.
RESULTS
Results indicated that emerging adults experienced numerous stressful events associated with the pandemic, as well as overall increases in symptoms of depression and traumatic intrusions during the pandemic. Furthermore, significant interactions between LPP reactivity to positive and threatening interpersonal stimuli and interpersonal stress exposure emerged in the prediction of internalizing symptoms, controlling for baseline symptoms. Under high exposure to interpersonal stressors, reduced positive LPPs predicted increases in depressive symptoms while enhanced threatening LPPs predicted increases in traumatic intrusions.
CONCLUSIONS
These findings highlight the mental health impacts of the COVID-19 pandemic on emerging adults, and the role of individual differences in neurophysiological reactivity to emotional stimuli in vulnerability for depression and traumatic intrusions following stress exposure.
背景
接触与2019冠状病毒病疫情相关的应激事件与抑郁和焦虑患病率的增加有关，这引发了关于某些个体在应激暴露后更易出现内化症状的脆弱性问题。
方法
这项前瞻性研究考察了以晚期正电位（LPP）事件相关电位为指标的对积极和威胁性人际刺激的神经生理反应性，以及人际疫情相关应激源的暴露，在预测疫情前到疫情期间内化症状变化中的作用。新兴成年人（n = 75）在疫情前最初完成内化症状测量和一项人际情感图像任务，同时记录脑电图，并在2020年5月的2019冠状病毒病疫情期间再次联系，以完成与疫情相关应激事件暴露和当前内化症状的测量。
结果
结果表明，新兴成年人经历了许多与疫情相关的应激事件，以及疫情期间抑郁症状和创伤性侵入症状的总体增加。此外，在控制基线症状的情况下，在预测内化症状时，LPP对积极和威胁性人际刺激的反应性与人际应激暴露之间出现了显著的交互作用。在高人际应激源暴露下，积极LPP降低预测抑郁症状增加，而威胁性LPP增强预测创伤性侵入增加。
结论
这些发现突出了2019冠状病毒病疫情对新兴成年人的心理健康影响，以及个体在对情感刺激的神经生理反应性方面的差异在应激暴露后抑郁和创伤性侵入易感性中的作用。
