Intimate Partner Violence (IPV) has been associated with cognitive, emotional, physical and physiological alterations, and with the presence of anxiety disorders. There is not enough research on this problem from an interdisciplinary approach despite the above. Therefore, this research compared the emotion perception and electrophysiological responses, elicited by an emotional task, in women who had experienced IPV and women who had not (WIPV). Forty-five participants (22 with and 23 without IPV experience) were presented with nine images from the International Affective Picture System (IAPS) database and performed a self-report using the Self-Assessment Manikin (SAM). In parallel, electrophysiological signals (ECG and EEG) were acquired, for the analysis of emotional response. In the between-group analysis, the IPV group showed lower perceived dominance and greater central asymmetry in the alpha band than the WIPV group; additionally, the IPV group exhibited a significant positive correlation between the valence of the images and the alpha band power in central areas. In the within-group analysis, the WIPV group showed greater activation in the alpha band and alpha/beta ratio in frontal areas during the emotional elicitation, as compared to baseline. Furthermore, the ECG analysis showed that, for the IPV group, there was a decrease in the power of the high-frequency (HF) band and an increase in the power of the very-low-frequency (VLF) band of heart rate variability (HRV) during the elicitation stage. It is hypothesized that the IPV group could present higher stress levels and greater physiological activity during emotional stimuli than the WIPV group. Possible changes in emotional regulation and anxiety levels due to IPV experiences are discussed.
亲密伴侣暴力(IPV)与认知、情绪、身体和生理改变以及焦虑症的存在有关。尽管如此,从跨学科角度对这一问题的研究仍不足。因此,本研究比较了经历过IPV的女性和未经历过IPV的女性(WIPV)在一项情绪任务中引发的情绪感知和电生理反应。45名参与者(22名有IPV经历,23名无IPV经历)观看了国际情感图片系统(IAPS)数据库中的九张图片,并使用自我评估人体模型(SAM)进行了自我报告。同时,采集了电生理信号(心电图和脑电图),用于分析情绪反应。在组间分析中,IPV组在α波段的感知优势较低,中央不对称性比WIPV组更大;此外,IPV组在中央区域的图片效价与α波段功率之间呈现出显著的正相关。在组内分析中,与基线相比,WIPV组在情绪诱发期间额叶区域的α波段和α/β比值激活程度更高。此外,心电图分析表明,对于IPV组,在诱发阶段心率变异性(HRV)的高频(HF)波段功率降低,极低频(VLF)波段功率增加。据推测,与WIPV组相比,IPV组在情绪刺激期间可能表现出更高的压力水平和更大的生理活动。文中讨论了由于IPV经历导致的情绪调节和焦虑水平的可能变化。
