Abstract Experimental studies applying cognitive bias modification of attention (CBM-A) and interpretation (CBM-I) to reduce aggression have examined the effect of modifying each cognitive bias in isolation. In order to maximise the potential impact on both biases and symptom reduction, we examined whether a combined bias training procedure targeting both attention and interpretation biases (CBM-AI) in combination would be more effective than targeting interpretation bias (CBM-I) alone. University students (17–35 years) were randomly assigned to either a single session of CBM-AI training (n = 40), CBM-I training (n = 40), or a control condition (n = 40). Contrary to our expectations, participants showed an increase in adaptive attention and pro-social interpretation bias in all training conditions. Additionally, in none of the conditions, we found a significant change on self-reported or behavioural aggression. These findings suggest: (1) that the combined training did not have added effect over single interpretation bias training, (2) that training interpretation bias may lead to changes in attention bias, (3) that elements of the control condition unexpectedly, but interestingly, also affected attention and interpretation biases, and (4) single-session CBM procedures do not produce robust effects on self-report or behavioural measures of aggression in unselected samples.
应用注意认知偏差修正(CBM-A)和解释认知偏差修正(CBM-I)来降低攻击行为的实验研究考察了单独修正每一种认知偏差的效果。为了最大限度地提高对偏倚和症状减轻的潜在影响,我们研究了针对注意力和解释偏倚(CBM-AI)的联合偏倚训练程序是否比单独针对解释偏倚(CBM-I)更有效。17-35岁的大学生被随机分配到单次CBM-AI训练(n = 40)、CBM-I训练(n = 40)或对照条件(n = 40)。与我们的预期相反,参与者在所有训练条件下都表现出适应性注意和亲社会解释偏见的增加。此外,在任何一种情况下,我们都没有发现自我报告或行为攻击的显著变化。这些发现表明:(1)联合训练并没有比单一解释偏见训练产生额外的效果;(2)训练解释偏见可能导致注意偏见的变化;(3)控制条件的元素出乎意料地(但有趣的是)也影响了注意和解释偏见;(4)单次CBM程序对非选择样本的自我报告或攻击行为测量没有产生强大的影响。

The presence of body dissatisfaction (BD) in non-Western countries is an important area of empirical enquiry. The results reflect collectivistic and individualistic cultures of Malaysians and Australians, respectively, whereby social approval, social acceptance, and cultural values are of high importance to Malaysians compared with the more liberal attitudes of Australians with respect to health behaviours. This study sought to compare: (1) Australian and Malaysian women on BD, thin ideal internalisation, sociocultural influences, problematic weight-related behaviours, and health behaviours; and (2) the degree to which BD is associated with health behaviours (smoking, alcohol consumption, drug use, and sexual behaviours) across the two cultures. Participants were 428 Australian females and 402 Malaysian females aged 18–25 years old. Australians had higher BD, thin ideal internalisation, family and media influences, restrained eating, and poorer health behaviours, while Malaysians had higher peer influence. There was no difference for bulimic behaviours across the two countries. BD was found to have an association with use of drugs, smoking, and sexual behaviours among Malaysian women, but not for Australian participants. The permeation of Western standards of the thin ideal due to increased industrialisation, Westernisation, and modernisation has brought about bulimic behaviours in Malaysian women, similar to that of Australian women.
在非西方国家,身体不满(BD)的存在是实证研究的一个重要领域。结果分别反映了马来西亚人和澳大利亚人的集体主义和个人主义文化,与澳大利亚人对健康行为的更自由的态度相比,社会认可、社会接受和文化价值观对马来西亚人来说非常重要。本研究试图比较:(1)澳大利亚和马来西亚女性的双相障碍、理想瘦内化、社会文化影响、有问题的体重相关行为和健康行为;(2)两种文化中双相障碍与健康行为(吸烟、饮酒、吸毒和性行为)的关联程度。参与者是428名澳大利亚女性和402名马来西亚女性,年龄在18-25岁之间。澳大利亚人有较高的抑郁、较弱的理想内化、家庭和媒体影响、节制饮食和较差的健康行为,而马来西亚人有较高的同伴影响。两国的暴食行为没有差异。在马来西亚女性中发现BD与吸毒、吸烟和性行为有关,但在澳大利亚参与者中没有发现。由于工业化、西方化和现代化程度的提高,西方理想瘦标准的渗透给马来西亚女性带来了与澳大利亚女性相似的暴食行为。

This study investigated whether positive feedback from same-age peers can modify self-relevant cognitive processes of high socially anxious youth in a positive direction. Thirty-three high socially anxious and 32 non-socially anxious undergraduate students (17–22 years) gave an impromptu speech and received either positive or neutral feedback post-speech. Anticipatory processing (AP) was rated prior to the speech via self-report. One week later participants returned to the laboratory and completed questionnaires assessing post-event processing (PEP) thoughts related to the impromptu speech and AP about a future speech. For high socially anxious youth receiving positive feedback, AP about their speech performance significantly improved over time. In addition, high socially anxious participants who received positive feedback reported a higher frequency of positive PEP thoughts about their speech in the intervening week. These improvements did not occur in the neutral peer feedback condition. Non-socially anxious participants’ AP improved in both feedback conditions, whereas their frequency of PEP was unaffected by feedback. These findings suggest that, in high socially anxious youth, positive feedback from same-age peers can modify self-relevant cognitive processes in a positive direction. We discuss how methodological improvements could more thoroughly investigate the potential of positive peer feedback for changing cognitions.
摘要本研究旨在探讨来自同龄同伴的积极反馈是否能正向调节高社交焦虑青少年的自我相关认知过程。33名高社交焦虑大学生和32名非社交焦虑大学生(17-22岁)进行了即兴演讲,并在演讲后得到了积极或中立的反馈。预期加工(AP)在演讲前通过自我报告进行评定。一周后,参与者回到实验室,完成问卷,评估与即兴演讲相关的事件后处理(PEP)想法和对未来演讲的预估。对于接受积极反馈的高社交焦虑青少年,随着时间的推移,他们对语言表现的认知能力显著提高。此外,收到积极反馈的高社交焦虑参与者报告说,在中间的一周内,他们对自己的演讲产生积极PEP想法的频率更高。这些改善在中立的同伴反馈条件下没有发生。非社交焦虑参与者的AP在两种反馈条件下都有所改善,而他们的PEP频率不受反馈的影响。这些发现表明,在高度社交焦虑的青少年中,来自同龄同伴的积极反馈可以朝着积极的方向改变自我相关的认知过程。我们讨论了方法的改进如何能够更彻底地调查积极的同伴反馈对改变认知的潜力。

The purpose of this study was to develop and provide a preliminary validation of a new measure of scrupulosity, the Scrupulous Thoughts and Behaviours Questionnaire (STBQ). More specifically, the STBQ was designed to assess a range of scrupulosity-related thoughts/obsessions and behaviours/compulsions. Following item development, a sample of non-referred college students completed the STBQ along with numerous validation measures. Based on factor analyses, a two-factor solution was retained. The first factor consisted of items that measure scrupulosity-themed obsessions and thoughts, and the second factor consisted of items that measure scrupulosity-themed compulsions and related behaviours. Support was found for the validity of STBQ, as both subscales were significantly and positively associated with measures of relevant constructs, including the Pennsylvania Inventory of Scrupulosity-Revised, the only other self-report measure of scrupulosity, thought–action fusion, religiosity, and obsessive–compulsive disorder symptoms. As the first known self-report measure to assess scrupulosity obsessions and compulsions, the STBQ has a potential utility in clinical practice and research.
本研究的目的是开发一种新的谨慎性衡量标准,即仔细思考和行为问卷(STBQ),并对其进行初步验证。更具体地说,STBQ旨在评估一系列与谨慎相关的想法/痴迷和行为/强迫。在项目开发之后,非转介大学生的样本完成了STBQ以及许多验证措施。基于因素分析,保留了一个双因素解决方案。第一个因素由衡量以谨慎为主题的痴迷和想法的项目组成,第二个因素由测量以谨慎为标题的强迫和相关行为的项目组成。STBQ的有效性得到了支持,因为这两个分量表都与相关结构的测量值显著正相关,包括宾夕法尼亚州审查量表修订版,这是唯一一个关于谨慎、思想-行动融合、宗教信仰和强迫症症状的自报测量值。STBQ作为已知的第一种评估谨慎强迫症和强迫性的自我报告指标,在临床实践和研究中具有潜在的实用性。

Anxiety sensitivity (AS) is a common vulnerability in emotional disorders. Due to the pathological role of AS, individuals with high AS are faced with emotional problems. Thus, cognitive behavioural interventions try to reduce these problems by targeting AS. The present study aimed to compare the efficacy of transdiagnostic cognitive behavioural therapy (T-CBT) and construct-specific CBT (CS-CBT) on AS, anxiety, depression, and positive and negative affect in these patients. To this end, 40 patients with high AS were randomly assigned to one of the three groups of T-CBT, CS-CBT, and wait list. Participants were assessed using the Anxiety and Related Disorders Interview Schedule for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Anxiety Sensitivity Index-3, Beck Anxiety Inventory, Beck Depression Inventory-II, and Positive and Negative Affect Schedule at baseline, post-treatment, 3-month follow-up, and 6-month follow-up. The findings showed that T-CBT and CS-CBT have a significant effect on AS, anxiety, and negative affect; however, contrary to T-CBT, CS-CBT is not effective for reducing depression and positive affect. T-CBT had a more promising efficacy than CS-CBT in all treatment outcomes. The results show better and more stable efficacy of T-CBT among patients with high AS. It is essential to consider AS as a target for cognitive behavioural intervention for the spectrum of emotional disorders.
焦虑敏感性(AS)是情绪障碍中一种常见的脆弱性。由于AS的病理作用,高AS患者面临情绪问题。因此,认知行为干预试图通过靶向AS来减少这些问题。本研究旨在比较跨诊断认知行为疗法(T-CBT)和构建特异性CBT(CS-CBT)对这些患者的AS、焦虑、抑郁以及积极和消极影响的疗效。为此,40名高AS患者被随机分配到T-CBT、CS-CBT和等待名单三组中的一组。在基线、治疗后、3个月随访和6个月随访时,使用《精神障碍诊断与统计手册》第五版的焦虑和相关障碍访谈表、焦虑敏感指数-3、贝克焦虑量表、贝克抑郁量表II以及积极和消极情绪表对参与者进行评估。结果表明,T-CBT和CS-CBT对AS、焦虑和负面情绪有显著影响;然而,与T-CBT相反,CS-CBT在减少抑郁和积极情绪方面无效。在所有治疗结果中,T-CBT比CS-CBT更有希望。研究结果表明,T-CBT在高AS患者中的疗效更好、更稳定。将AS视为一种针对情绪障碍的认知行为干预的靶点是至关重要的。

The Role of Disgust and Threat in Contamination-Related Obsessive–Compulsive Disorder 厌恶和威胁在污染相关强迫症中的作用

Theoretical models suggest that the emotion disgust or threat overestimates are important in the aetiology and maintenance of contamination-based obsessive–compulsive disorder. In the current study, both threat and disgust were manipulated and 115 non-clinical participants (mean age 20.46 years, 94 females) were randomly allocated to one of four conditions: high-disgust/low-threat (n = 29), high-disgust/high-threat (n = 29), low-disgust/low-threat (n = 27), and low-disgust/high-threat (n = 30). Participants completed a hierarchical Behavioural Avoidance Task (BAT). Those in the high-threat and high-disgust conditions completed less BAT steps and showed more latency to begin each step than those in the low-threat and low-disgust conditions. A significant interaction effect was observed for the high-disgust/high-threat condition as significantly more task avoidance was found. However, handwashing duration was not significantly different between the high and low-disgust conditions or the high and low-threat conditions. The overall low mean washing duration of 30 s possibly due to the testing conditions and/or the ethnic heterogeneity of the sample may account for these results. There were also no significant differences in the level of anxiety for participants in the high-threat compared with the low-threat conditions. It is possible that anxiety remained relatively low across conditions as a result of the graduated BAT. Future research and theoretical and clinical implications are discussed.
理论模型表明,情绪厌恶或威胁高估在基于污染的强迫症的病因和维持中很重要。在当前的研究中,威胁和厌恶都被操纵,115名非临床参与者(平均年龄20.46岁,94名女性)被随机分配到四种情况中的一种:高厌恶/低威胁(n=29)、高厌恶/高威胁(n=27)、低厌恶/低威胁(n=30)。参与者完成了分层行为回避任务(BAT)。与低威胁和低厌恶条件下的人相比,在高威胁和高厌恶条件下完成的BAT步骤更少,并且每一步开始的延迟更多。在高厌恶/高威胁条件下观察到显著的交互效应,因为发现了显著更多的任务回避。然而,在高厌恶程度和低厌恶程度以及高威胁程度和低威胁程度之间,洗手时间没有显著差异。可能由于测试条件和/或样本的种族异质性,30 s的总体平均洗涤持续时间较低,这可能是这些结果的原因。与低威胁条件相比,高威胁条件下参与者的焦虑水平也没有显著差异。由于BAT的分级,焦虑可能在各种情况下保持相对较低。讨论了未来的研究以及理论和临床意义。

While chronic worry is typically associated with cautious and harm-avoidant behaviours, there is evidence that people high in chronic worry are characterised by negative urgency (NU), that is, the propensity to act rashly when experiencing negative affect. The present study was a preliminary examination of how rash action and impulsive decision-making manifest for chronic worriers compared to individuals low in worry. In total, 93 participants who endorsed high and low worry and NU responded to open-ended questions about their experience of NU on Amazon Mechanical Turk. Themes were identified using a data-driven approach. Participants high in chronic worry endorsed significantly greater NU compared to those low in worry. However, the types of NU behaviours were similar across participants, with a majority of responses involving initiating interpersonal conflict. Other themes included spending money, excessive eating, alcohol use, and aggressive behaviours. The manifestations of NU were largely consistent with those described in the model of NU. Although individuals higher in chronic worry engaged in NU behaviours to a greater extent, the types of behaviours were similar to those reported by people lower in worry. More research is needed to understand the characteristics of NU-motivated behaviour in individuals high in chronic worry.
虽然慢性焦虑通常与谨慎和避免伤害的行为有关,但有证据表明,慢性焦虑高的人的特征是消极紧迫性(NU),也就是说,当经历负面影响时,他们倾向于轻率行事。目前的研究是对慢性忧虑者与低忧虑者相比的轻率行为和冲动决策的初步检验。总共有93名支持高、低担忧和NU的参与者回答了关于他们在亚马逊土耳其机械上使用NU的体验的开放式问题。使用数据驱动的方法确定主题。与那些低焦虑的参与者相比,高慢性焦虑的参与者认可了更大的NU。然而,不同参与者的不情愿行为类型是相似的,大多数反应涉及引发人际冲突。其他主题还包括花钱、暴饮暴食、酗酒和攻击性行为。NU的表现与NU模型的描述基本一致。尽管慢性焦虑程度较高的个体在更大程度上参与了NU行为,但其行为类型与焦虑程度较低的个体相似。需要更多的研究来了解长期焦虑高的个体的nu动机行为的特征。

Triple P is a parenting programme used in the youth healthcare practice of many Dutch municipalities to support parents in raising their children. According to international research, this Australian intervention is effective for parents with children up to the age of 12. It shows positive effects on parenting skills and on the reduction of both parents' child-rearing stress and their children's behavioural and emotional problems. Our study examined the effectiveness of Teen Triple P level 4: a training programme for parents of teenagers aged 10–16. The programme included five group sessions of 1.5–2 h each, as well as three individual (phone) consultations. Through a matching procedure, 103 parents who participated in Teen Triple P were compared in a quasi-experimental study with 397 parents in a control group. Compared with the control group, parents who received the Teen Triple P training reported a significant improvement in their parental practice. Now, they are more involved with their child, more responsive to the needs of the children, and they report fewer parent–child conflicts. Some positive differences in behavioural problems among adolescents, as reported by their parents, could be found among the experimental group. These findings remained the same at the follow-up.
3p是荷兰许多市政当局在青年保健实践中使用的一项育儿方案,以支持父母抚养子女。根据国际研究,澳大利亚的这种干预对12岁以下孩子的父母有效。它对育儿技巧和减少父母双方的育儿压力以及孩子的行为和情感问题都有积极的影响。我们的研究考察了青少年3p四级的有效性:一个针对10-16岁青少年父母的培训项目。该方案包括五次小组会议,每次1.5-2小时,以及三次个人(电话)咨询。通过配对程序,103名参加青少年3p的父母与397名对照组的父母在准实验研究中进行了比较。与对照组相比,接受青少年3p训练的父母报告说,他们的父母实践有了显著的改善。现在,他们更多地与孩子在一起,对孩子的需求反应更积极,他们报告的亲子冲突也更少了。在青少年的行为问题上,正如他们的父母所报告的,可以在实验组中发现一些积极的差异。这些发现在随访中保持不变。

According to cognitive theories of social anxiety, fear of negative evaluation (FNE) may be the mechanism whereby social anxiety induces distress. However, studying this can be challenging, as individuals with social anxiety may be reluctant to enter anxiety-provoking social situations, such as speaking in front of others. The present study used virtual reality (VR) to examine if giving a presentation in front of a virtual audience induced distress among undergraduate students and to test the hypothesis that FNE would mediate the relationship between social anxiety and distress. University students (N = 58, 70% female) entered a VR environment where they stood in front of a virtual audience and gave a short, impromptu presentation about their university. Participants also completed self-report measures of social anxiety, FNE, and distress (estimated before, during, and after VR). Distress and FNE had positive relationships with social anxiety and FNE fully mediated the relationship between social anxiety and distress. As far as we are aware, this is the first VR study to show this effect. The findings indicate that FNE could be a useful treatment target to reduce distress when presenting in front of an audience, either in VR or in person.
根据社交焦虑的认知理论,负面评价恐惧(FNE)可能是社交焦虑诱发痛苦的机制。然而,研究这一点可能具有挑战性,因为患有社交焦虑症的人可能不愿意进入引发焦虑的社交场合,比如在别人面前讲话。本研究利用虚拟现实技术(VR)来检验大学生在虚拟观众面前做演讲是否会引起焦虑,并检验FNE在社交焦虑和焦虑之间的关系中起中介作用的假设。大学生(N = 58, 70%为女性)进入一个虚拟现实环境,站在虚拟观众面前,对自己的大学做一个简短的即兴演讲。参与者还完成了社交焦虑、FNE和痛苦的自我报告测量(在VR之前、期间和之后进行评估)。苦恼、FNE与社交焦虑呈显著正相关,FNE在社交焦虑与苦恼的关系中起完全中介作用。据我们所知,这是第一个显示这种效果的VR研究。研究结果表明,FNE可能是一个有用的治疗目标,可以减少在VR或真人观众面前演讲时的痛苦。

The Effect of Comorbid Depression on Sudden Gains During Transdiagnostic Cognitive-Behavioural Therapy for Anxiety Disorders 共病性抑郁对焦虑症跨诊断认知行为治疗中突然获益的影响

During psychotherapy some patients experience large symptom improvements between sessions, termed sudden gains. Most commonly, sudden gains are observed during treatment for depression (40–50% of participants), but these are occasionally also observed in treatment for anxiety (15–20%). This study investigated the impact of comorbid depression on sudden gains in a primary anxiety sample. It was hypothesised that sudden gains would occur more frequently in participants with anxiety and comorbid depression than anxiety-only participants. The sample consisted of 58 adults who participated in a 12-week transdiagnostic cognitive-behavioural therapy (tCBT) programme. Sudden gains were more frequent in the comorbid depression group than in the anxiety-only group. Sudden gains may be predominantly a function of depressive disorders, which supports the higher rates seen in depressive disorders compared with anxiety disorders. Future research should endeavour to replicate these findings, as this was the first study designed to specifically investigate comorbidity in sudden gains.
在心理治疗过程中,一些患者在两次治疗之间症状有了很大的改善,称为突然好转。最常见的是,在抑郁症治疗期间(40-50%的参与者)会观察到突然的好转,但在焦虑症治疗中偶尔也会观察到(15-20%)。本研究调查了原发性焦虑样本中共病抑郁症对突然增加的影响。有人假设,与只有焦虑的参与者相比,有焦虑和共病抑郁的参与者会更频繁地出现突然的收获。该样本由58名成年人组成,他们参加了为期12周的跨诊断认知行为疗法(tCBT)计划。与单纯焦虑组相比,合并抑郁组的突然好转更为频繁。突然增加可能主要是抑郁障碍的一种功能,这支持了与焦虑障碍相比,抑郁障碍的发病率更高。未来的研究应该努力复制这些发现,因为这是第一项专门研究突然增加的合并症的研究。
