Alexithymic individuals have difficulties processing emotional stimuli, including faces, and may require more resources to process such stimuli. Alexithymia may interact with task characteristics, like perceptual load, which modulates the processing capacity allocated to task-relevant, versus task-irrelevant stimuli. We examined effects of load and distractor type (face, object) and valence (threatening, neutral), and alexithymia on performing a letter-search task. We assessed reaction time, accuracy, and heart rate to index arousal and cognitive effort. Perceptual load, distractor presence, type and valence showed expected effects. Alexithymia did not meaningfully affect reaction time, but was associated with decreased accuracy when distractors were threatening, under low perceptual load. HR did not suggest changes in resources mobilized depending on alexithymia level. Results suggest that alexithymic individuals perceived emotional stimuli and were able to maintain intact reaction time, though this came with a cost in accuracy. Absence of HR effects suggests that no additional resources were recruited to remedy this difficulty. Overall, results suggest that emotional stimuli are perceived in alexithymia at early stages, but resources are not appropriately allocated to prevent performance impairment.
述情障碍患者在处理情绪刺激(包括面部)方面有困难,可能需要更多的资源来处理这些刺激。述情障碍可能与任务特征相互作用,如知觉负荷,它调节分配给任务相关和任务无关刺激的处理能力。我们研究了负载和干扰物类型(面孔、物体)、效价(威胁性、中性)以及述情障碍对执行字母搜索任务的影响。我们评估了反应时间、准确性和心率来衡量觉醒和认知努力。知觉负荷、干扰物存在、类型和效价均有预期的影响。述情障碍对反应时间没有显著影响,但在低知觉负荷下,当干扰物具有威胁性时,与准确性下降有关。HR并没有建议资源调动的变化取决于述情障碍的程度。结果表明,述情障碍个体感知情绪刺激并能够保持完整的反应时间,尽管这是以准确性为代价的。人力资源效应的缺失表明没有额外的资源来弥补这一困难。总的来说,结果表明情绪刺激在述情障碍的早期阶段被感知,但资源没有适当分配以防止表现障碍。

Borderline Personality Disorder (BPD) is a mental disorder characterized by significant impairment in intrapersonal and interpersonal functioning, as well as patterns of personality pathology. Memory deficits are not recognized as a core symptom of BPD, but individuals with BPD symptoms have long been suspected to have inaccurate perceptions, disturbed memory processes, and an increased tendency to develop false memories. In the present study, we examined whether there was an association between BPD features and the production of false memories in the Deese-Roediger-McDermott (DRM) paradigm—a laboratory-based procedure that is frequently used to investigate false memory. We also compared the traditional categorical BPD criteria (DSM-5 Section II) with the alternative model of personality disorders BPD criteria (DSM-5 Section III) in predicting memory performance. A total of 298 university students completed the McLean Screening Instrument for Borderline Personality Disorder, SCID-II Personality Questionnaire, Borderline Personality Disorder Impairment Scale, Personality Inventory for DSM-5, Beck Depression Inventory, Dissociative Experiences Scale, and Traumatic Life Events Questionnaire. Participants were also tested using both traditional DRM word lists as well as word lists that were specifically associated with BPD features. Using the traditional diagnosis of BPD, BPD features were correlated with higher false memory for positive information; in the alternative model of BPD, identity impairment and anxiousness were correlated with the overall false memory score. We also found that trauma and dissociation mediated the relation between BPD and false memory. These findings are discussed in terms of how the consequences of trauma, such as dissociation and identity disturbance, are associated with false memory. Whether false memory rates are higher in a clinical population of BPD patients than in non-clinical volunteers remains to be determined.
边缘型人格障碍(BPD)是一种精神障碍,其特征是人际和人际功能的严重损害,以及人格病理模式。记忆缺陷并不被认为是BPD的核心症状,但长期以来,人们一直怀疑有BPD症状的个体有不准确的感知,记忆过程紊乱,以及产生错误记忆的倾向增加。在本研究中,我们用Deese-Roediger-McDermott (DRM)范式检验了BPD特征与错误记忆的产生之间是否存在关联。DRM范式是一种经常用于研究错误记忆的实验室程序。我们还比较了传统的分类BPD标准(DSM-5第2节)和人格障碍备选模型BPD标准(DSM-5第3节)在预测记忆表现方面的效果。298名大学生完成了麦克林边缘型人格障碍筛查量表、SCID-II型人格问卷、边缘型人格障碍损害量表、DSM-5型人格问卷、贝克抑郁量表、分离体验量表和创伤性生活事件问卷。参与者还使用传统的DRM单词列表和专门与BPD特征相关的单词列表进行了测试。在传统的BPD诊断中,BPD特征与较高的阳性信息错误记忆相关;在BPD备选模型中,身份障碍和焦虑与错误记忆总分相关。我们还发现创伤和分离介导了BPD与错误记忆之间的关系。这些发现讨论了创伤的后果,如分离和身份障碍,是如何与错误记忆相关的。临床人群中BPD患者的错误记忆率是否高于非临床志愿者仍有待确定。

Research examining emotion dysregulation and posttraumatic stress disorder (PTSD) has seen tremendous growth over the past decade. However, past investigations have almost exclusively relied on cross-sectional designs and have neglected to consider the potential role of dysregulation stemming from positive emotions. The current study utilized rigorous methodology (experience sampling) and statistics (dynamic structural equation modeling) to explicate daily reciprocal associations between negative and positive emotion dysregulation and PTSD symptoms. Participants were 145 community women (M age = 40.66, 40.7% white) experiencing intimate partner violence (IPV) and using substances who participated in a baseline interview and then completed surveys three times a day for 30 days. Results at the between-person level showed that women who reported higher negative and positive emotion dysregulation also reported more PTSD symptoms. At the within-person level, findings supported a significant contemporaneous effect between positive emotion dysregulation and PTSD symptoms. Further, there was a significant cross-lagged effect from negative emotion dysregulation to next-interval PTSD symptoms. Results suggest that positive emotion dysregulation co-occurs with PTSD symptoms and that negative emotion dysregulation predicts PTSD symptoms. Findings provide additional support for the utility of addressing both negative and positive emotion dysregulation in the treatment of PTSD among women experiencing IPV.
在过去的十年里,对情绪失调和创伤后应激障碍(PTSD)的研究有了巨大的增长。然而,过去的研究几乎完全依赖于横断面设计,而忽略了考虑来自积极情绪的失调的潜在作用。目前的研究采用严格的方法(经验抽样)和统计(动态结构方程模型)来解释消极和积极情绪失调与创伤后应激障碍症状之间的日常相互关联。参与者为145名遭受亲密伴侣暴力(IPV)和使用物质的社区妇女(M年龄= 40.66,白人40.7%),她们参加了基线访谈,然后每天完成三次调查,持续30天。人与人之间水平的结果显示,报告较高的消极和积极情绪失调的女性也报告了更多的创伤后应激障碍症状。在个人层面上,研究结果支持积极情绪失调和创伤后应激障碍症状之间的显著同步效应。此外,负性情绪失调对下一间隔PTSD症状存在显著的交叉滞后效应。结果表明,积极情绪失调与PTSD症状共存,消极情绪失调可预测PTSD症状。研究结果为解决消极和积极情绪失调在治疗IPV女性创伤后应激障碍中的效用提供了额外的支持。

Urgency, the trait-like tendency to respond to heightened emotion states with rash action, has been associated with both non-suicidal self-injury (NSSI) and suicide attempts (Lynam et al., 2011). Limited research has sought to identify specific emotions that may trigger NSSI or suicide attempts for those with high urgency. We examined shame as a candidate emotion. We hypothesized that greater shame-proneness, in combination with greater urgency, would explain unique variance in NSSI and suicide attempt history in two community samples (Ns = 192 and 225). Logistic and negative binomial regression analyses examined the effects of shame, urgency, and their interaction on the presence (vs. absence) and frequency of NSSI and suicide attempts. The proposed interaction of shame and urgency was related to greater risk and frequency of NSSI and suicide attempts when examining simple slopes, across the six models tested, particularly when urgency was high. Further research should examine shame as a trigger for self-harm in the context of heightened urgency using time series designs.
紧迫感是一种对情绪状态升高做出鲁莽行为反应的特质倾向,它与非自杀性自伤(NSSI)和自杀企图都有关系(Lynam et al., 2011)。有限的研究试图确定可能引发高度紧急的自伤或自杀企图的特定情绪。我们将羞耻感作为一种候选情绪进行了研究。我们假设,更大的羞耻倾向,结合更大的紧迫感,可以解释两个社区样本(Ns = 192和225)中自伤和自杀未遂史的独特差异。逻辑回归和负二项回归分析检验了羞耻感、紧迫感及其相互作用对自伤和自杀企图的存在(相对于不存在)和频率的影响。在测试的六个模型中,当检查简单斜坡时,羞耻感和紧迫感之间的相互作用与自伤和自杀企图的更高风险和频率有关,特别是当紧迫性很高时。进一步的研究应该使用时间序列设计来检验羞耻感是否会在高度紧急的情况下引发自残。

Most studies on the psychometric properties of the Cognitive Emotion Regulation Questionnaire (CERQ) were done in adolescents and adults. The scarce studies in older adults were mainly limited to associations of CERQ scales with internalising symptoms and wellbeing. Only one study explored the underlying factor structure in Spanish older adults and concluded that only a 27 item CERQ version showed adequate fit when tested with confirmatory factor analysis. The present study analyses the psychometric properties of all three versions of the CERQ in a sample of 451 community-dwelling older adults: the original 36 item CERQ, the short 18 item CERQ developed by the original authors and a Spanish 27 item CERQ version. Because gender differences among strategies used have been reported, the present study examined and provided first evidence for the gender invariance of the CERQ structure. Moreover, cognitive emotion regulation strategies correlated like hypothesized with clinical symptoms in general, and behavioural inhibition and activation systems and coping styles. The nomological net was highly similar for the original CERQ and shortened versions. The shortened versions of the CERQ consequently can be viable alternatives to the CERQ in settings where short assessment instruments are needed.
关于认知情绪调节问卷(CERQ)心理测量特性的研究大多是在青少年和成人中进行的。老年人的稀缺研究主要局限于CERQ量表与内化症状和健康的关联。只有一项研究探索了西班牙老年人的潜在因素结构,并得出结论,只有27项CERQ版本在进行验证性因素分析时显示出足够的契合度。本研究以451名社区老年人为样本,分析了三个版本的CERQ的心理测量特性:原始的36项CERQ,原作者开发的短18项CERQ和西班牙语27项CERQ版本。由于所使用的策略之间存在性别差异,因此本研究对CERQ结构的性别不变性进行了检查并提供了第一个证据。此外,认知情绪调节策略与临床症状、行为抑制和激活系统以及应对方式的相关性与假设一致。原始CERQ和缩短版本的词法网络非常相似。因此,在需要短期评估工具的情况下,CERQ的缩短版本可以成为CERQ的可行替代方案。

The COVID-19 pandemic has caused pervasive disruptions to family life. In light of the established role of parent-child dynamics in the maintenance of pediatric anxiety, we conducted a multilevel, multimodal study to examine how family-level factors moderate anxious youths’ responses to the COVID-19 pandemic. Prior to the pandemic (“pre-pandemic”), children with anxiety disorders (n = 28; ages 6-12) completed an fMRI task probing parental modulation of amygdala reactivity to fearful faces. During the first peak of the COVID-19 pandemic (“mid-pandemic”), parents completed questionnaires about their family’s exposure to COVID-19-related stress, their child’s COVID-19-related fears and behaviors, and their own (parental) functioning. Pre-pandemic parental modulation of amygdala reactivity moderated the association between children’s exposure to COVID-19-related stress and their COVID-19-related fears and behaviors. Furthermore, greater mid-pandemic parental assistance with their child’s use of venting and with their child’s use of expressive suppression as emotion regulation strategies exacerbated the effects of COVID-19-related stress on children’s COVID-19-related fears and behaviors, respectively. These results provide preliminary insight into the ways in which distinct family-level factors may buffer or exacerbate the effects of COVID-19-related stress on youth with a history of anxiety disorders.
2019冠状病毒病大流行对家庭生活造成了普遍干扰。鉴于亲子动态在儿童焦虑维持中的既定作用,我们开展了一项多层次、多模式的研究,以研究家庭层面因素如何调节焦虑青少年对COVID-19大流行的反应。在大流行之前("大流行前"),患有焦虑症的儿童(n = 28;6-12岁)完成了一项功能磁共振成像任务,探测父母对恐惧面孔的杏仁核反应的调节。在COVID-19大流行的第一个高峰(“大流行中期”)期间,父母完成了关于其家庭面临COVID-19相关压力、子女与COVID-19相关的恐惧和行为以及他们自己(父母)功能的问卷调查。大流行前父母对杏仁核反应性的调节调节了儿童暴露于covid -19相关压力与其covid -19相关恐惧和行为之间的关联。此外,大流行中期父母对孩子使用发泄和孩子使用表达抑制作为情绪调节策略的更多帮助,分别加剧了与covid -19相关的压力对儿童与covid -19相关的恐惧和行为的影响。这些结果初步了解了不同的家庭因素如何缓冲或加剧与covid -19相关的压力对有焦虑症病史的青年的影响。

Receipt of both positive and negative social feedback is associated with psychophysiological responses, and such responses vary based on levels of internalizing symptoms and associated cognitive constructs. However, research examining the relationship between physiological response to social feedback and internalizing symptoms is mixed, and there is a need to develop salient tasks to assess responses to social feedback. This paper reports on two studies that examined physiological response to social feedback in undergraduate students using the Chatroom Interact Task (CIT). We also explored associations between physiological response to social feedback and internalizing symptoms and associated constructs. Participants were 48 (35 female; Study 1) and 65 (55 female; Study 2) undergraduate students. Participants completed self-report questionnaires of internalizing symptoms and associated cognitive constructs. They also completed the CIT to assess response to acceptance and rejection, while physiological data, including electrocardiogram and respiration to derive respiratory sinus arrhythmia (RSA), were acquired. Results across both studies were largely consistent. There were significant differences in RSA during the questionnaire phase and the neutral and acceptance/rejection phases of the CIT.

接受积极和消极的社会反馈与心理生理反应有关,这种反应根据内化症状的水平和相关的认知结构而变化。然而,对社会反馈的生理反应与内化症状之间关系的研究是混杂的,有必要制定突出的任务来评估对社会反馈的反应。本文报道了两项利用聊天室互动任务(CIT)检测大学生对社会反馈的生理反应的研究。我们也探讨了对社会反馈的生理反应与内化症状和相关构念之间的联系。参与者48人(女性35人;研究1)和65(55名女性;研究本科生。参与者完成内化症状和相关认知构念的自我报告问卷。他们还完成了CIT来评估对接受和拒绝的反应,同时获得了生理数据,包括心电图和呼吸,以得出呼吸性窦性心律失常(RSA)。两项研究的结果基本一致。问卷阶段、中立阶段和接受/拒绝阶段的RSA有显著差异,接受阶段和拒绝阶段的RSA无显著差异。内化症状和相关构念与RSA的差异无关。目前的研究表明,使用CIT来引起大学生对社会反馈的更高生理反应的有效性值得怀疑,并建议对社会反馈反应的未来研究和相关任务的设计进行重要考虑。

This paper reports on two studies that examined physiological response to social feedback in undergraduate students using the Chatroom Interact Task (CIT). We also explored associations between physiological response to social feedback and internalizing symptoms and associated constructs. Participants were 48 (35 female; Study 1) and 65 (55 female; Study 2) undergraduate students. Participants completed self-report questionnaires of internalizing symptoms and associated cognitive constructs. They also completed the CIT to assess response to acceptance and rejection, while physiological data, including electrocardiogram and respiration to derive respiratory sinus arrhythmia (RSA), were acquired. Results across both studies were largely consistent. There were significant differences in RSA during the questionnaire phase and the neutral and acceptance/rejection phases of the CIT. There were no differences between RSA during acceptance and rejection phases. Internalizing symptoms and associated constructs were not related to differences in RSA.

COVID-19 has significant impacts on young peoples’ lives and emotions. Understanding how young people maintain well-being in the face of challenges can inform future mental health intervention development. Here we applied network analysis to well-being data gathered from 2532 young people (12-25 years) residing in the UK during the COVID-19 pandemic to identify the structure across well-being and crucially, its central defining features. Gender and age differences in networks were also investigated. Across all participants, items emerged in two clusters: 1) optimism, positive self-perception, and social connectedness, and 2) processing problems and ideas. The two central features of well-being were: “I’ve been dealing with problems well” and “I’ve been thinking clearly”. There were minimal age and gender differences. Our findings suggest that the perception of being able to process problems and ideas efficiently could be a hallmark of well-being, particularly in the face of challenging circumstances. These findings contrast with pre-pandemic studies that point to positive affect as central aspects of well-being networks. Future interventions that encourage problem-solving and mental flexibility could be useful in helping young people maintain well-being during times of stress and uncertainty.
2019冠状病毒病对年轻人的生活和情绪产生了重大影响。了解年轻人在面对挑战时如何保持健康可以为未来的心理健康干预发展提供信息。在这里,我们对2019冠状病毒病大流行期间居住在英国的2532名年轻人(12-25岁)收集的幸福感数据进行了网络分析,以确定幸福感的结构,最重要的是,确定其核心定义特征。研究人员还调查了网络中的性别和年龄差异。在所有参与者中,出现的项目分为两类:1)乐观、积极的自我感知和社会联系,以及2)处理问题和想法。幸福的两个核心特征是:“我一直在很好地处理问题”和“我一直在清晰地思考”。年龄和性别差异很小。我们的研究结果表明,能够有效地处理问题和想法可能是幸福的标志,尤其是在面临挑战的情况下。这些发现与大流行前的研究形成对比,后者指出积极影响是福祉网络的核心方面。未来鼓励解决问题和心理灵活性的干预措施可能有助于帮助年轻人在压力和不确定时期保持健康。

Imagery rescripting (ImRs) of socially aversive memories is a promising intervention in the treatment of Social Anxiety Disorder. Little is known about the effects of ImRs on physiological responses to the rescripted socially aversive memory, which was the focus of this study in a healthy sample. Thirty individuals performed an imagination task measuring psychophysiological responses and subjective feelings (post-hoc) related to the rescripted memory, as well as to two control memories. In a within-subject design, participants completed the imagination task before and after a control intervention, and subsequently after one session ImRs of the socially aversive memory. At one-week follow-up, lasting effects on social anxiety and subjective feelings were assessed online (N = 26). ImRs of the socially aversive memory resulted in a significant reduction in negative feelings and activity of the corrugator supercilii, as well as a significant increase in valence and positive feelings related to the socially aversive memory compared to both control memories. However, only effects for positive feelings and corrugator supercilii were significantly stronger for ImRs compared to the control intervention. Lasting effects appeared for fear of negative evaluation and subjective emotional responses to the rescripted memory. These findings give preliminary evidence for the impact of ImRs on emotional aspects of the rescripted memory, indicating that ImRs might work through changing the representation of the aversive event in memory.
社交厌恶记忆的意象改写是治疗社交焦虑障碍的一种有前景的干预手段。关于ImRs对社会厌恶记忆的生理反应的影响,我们所知甚少,这是本研究在健康样本中的重点。30个人执行了一项想象任务,测量与指定记忆相关的心理生理反应和主观感受(事后),以及两个控制记忆。在受试者内部设计中,参与者在对照干预之前和之后完成了想象任务,随后在社会厌恶记忆的一个会话后完成了想象任务。在一周的随访中,对社交焦虑和主观感受的持续影响进行在线评估(N = 26)。与对照记忆相比,社会厌恶记忆的ImRs导致负面情绪和上睑肌活动的显著减少,以及与社会厌恶记忆相关的效价和积极情绪的显著增加。然而,与对照干预相比,ImRs仅对积极感觉和上睑皱肌的影响显着更强。对负面评价的恐惧和对重写记忆的主观情绪反应出现了持久的影响。这些发现为ImRs对指定记忆的情绪方面的影响提供了初步证据,表明ImRs可能通过改变记忆中厌恶事件的表征来起作用。

Implications of the Symptom-Level Overlap Among DSM Diagnoses for Dimensions of Psychopathology DSM诊断中症状水平重叠对精神病理维度的影响
Pub Date : 2023-02-20 DOI: 10.55913/joep.v1i1.6

Research on the patterns of covariation among mental disorders has proliferated, as summarized in the Hierarchical Taxonomy of Psychopathology (HiTOP). The aim of this brief descriptive study was to examine whether the repetition of symptoms among DSM-5 diagnoses is likely to be inflating the surface similarity of diagnoses in a way that artificially reinforces the dimensions that emerge when modelling patterns of disorder covariation or comorbidity. Specifically, the symptoms comprising the DSM-5 diagnostic criteria for all disorders covered by the HiTOP framework were examined for patterns of overlap that mirror the patterns of disorder covariation captured in HiTOP dimensions. I found that 358 pairs of the DSM-5 diagnoses covered by the HiTOP framework had one or more overlapping symptoms in their diagnostic criteria, and that a third (n = 130; 34%) of the unique constituent symptoms reinforced the higher-order structure of HiTOP through repetition within dimensions and/or between dimensions in the same superspectrum. By contrast, 86% of the possible pairs of diagnoses did not have any shared symptoms, and the majority of the symptoms (n = 222; 58%) did not influence the structure through repetition. Further, a fifth (n = 71; 19%) of the symptoms worked against the HiTOP structure by increasing the surface similarity of diagnoses under different subfactors, spectra, and superspectra. Overall, while patterns of symptom-level overlap do not appear strong enough to account for the emergence of HiTOP dimensions, these patterns do seem likely to inflate the similarity and consequent covariation of some DSM-5 diagnoses. Research on the statistical structure of psychopathology that uses DSM-5 diagnostic constructs should account for this potential source of bias.
精神病理分级分类法(HiTOP)总结了精神疾病共变模式的研究。这个简短的描述性研究的目的是检验DSM-5诊断中症状的重复是否可能以一种人为地加强在模拟疾病共变或共病模式时出现的维度的方式,夸大了诊断的表面相似性。具体而言,对HiTOP框架所涵盖的所有疾病的DSM-5诊断标准中包含的症状进行了检查,以寻找重叠模式,这些模式反映了HiTOP维度中捕获的疾病共变模式。我发现,HiTOP框架涵盖的358对DSM-5诊断在其诊断标准中有一个或多个重叠的症状,三分之一(n = 130;34%)的独特组成症状通过在同一超光谱的维度内和/或维度之间的重复加强了HiTOP的高阶结构。相比之下,86%的可能诊断对没有任何共同症状,大多数症状(n = 222;58%)没有通过重复影响结构。此外,五分之一(n = 71;19%)的症状通过增加不同子因子、谱和超谱下诊断的表面相似性而对HiTOP结构起作用。总的来说,虽然症状水平重叠的模式似乎不足以解释HiTOP维度的出现,但这些模式似乎确实可能夸大了一些DSM-5诊断的相似性和随之而来的协变。使用DSM-5诊断结构的精神病理学统计结构研究应该考虑到这种潜在的偏倚来源。
