Abstract
BACKGROUND Fear overgeneralization constitutes a susceptibility factor contributing to the development and maintenance of anxiety spectrum disorders. Extant research has demonstrated that exposure to positive and supportive social relationships attenuates fear acquisition and promotes the extinction of conditioned fear responses. However, the literature lacks investigation into the effect of secure attachment priming on inhibiting the generalization of conditioned fear. METHODS In this study, college students were recruited via online platforms to voluntarily engage in the experimental procedures, resulting in 57 subjects whose data were deemed suitable for analysis. The experimental protocol consisted of four consecutive phases: pre-acquisition, acquisition, priming, and generalization. The priming phase consisted of two experimental conditions: secure attachment priming (experimental group) and positive emotion priming (control group). This study adopted the perceptual discrimination fear conditioning paradigm, employing subjective expectancy of shock ratings and skin conductance responses as primary assessment indices. Individual difference variables were measured using corresponding psychological measurement scales. RESULTS In terms of generalization degree, a notable divergence surfaced in the skin conductance responses across various generalization materials between the secure attachment priming group and the control group. Similarly, during generalization extinction, a significant disparity emerged in the skin conductance responses across different generalization phases between the secure attachment priming group and the control group. In addition, individual differences analyses revealed that the inhibitory effect of secure attachment priming on fear generalization was not affected by intolerance of uncertainty and attachment orientations. Conversely, slope analyses confirmed that as intolerance of uncertainty increased, the inhibitory effect of positive emotion priming on fear generalization was attenuated. CONCLUSION The findings suggest that activating participants' representations of secure attachment via imagination effectively attenuates the generalization of perceptual fear at the physiological level. The inhibitory effect of secure attachment priming appears to be distinct from positive emotional modulation and remains unaffected by individual trait attachment styles. These results offer novel insights and avenues for the prevention and clinical intervention of anxiety spectrum disorders.

Abstract
According to the Learning Theory of Attachment, naturalistic learning experiences about others' responsiveness during distress are an underlying mechanism in the development of attachment. Previous studies have demonstrated attachment figures' unique safety-inducing effects in highly controlled conditioning procedures. Yet, neither have studies examined the presumed influence of safety learning on state attachment, nor have they examined how attachment figures' safety-inducing effects relate to attachment styles. To address these gaps, a differential fear conditioning paradigm was used in which pictures of participants' attachment figure and two control stimuli served as safety cues (CS-). US-expectancy and distress ratings were measured as indicators of fear responding. Results indicate that attachment figures evoked enhanced safety responding compared to control safety cues at the start of acquisition, which was maintained throughout acquisition and when presented together with a danger cue. Attachment figures' safety-inducing effects were reduced in individuals with higher attachment avoidance, although attachment style did not affect the rate of new safety learning. Finally, safe experiences with the attachment figure in the fear conditioning procedure resulted in diminished anxious state attachment. Adding to previous work, these findings underscore the importance of learning processes for attachment development and attachment figures' provision of safety.

Abstract
Current conceptualisations of posttraumatic stress disorder (PTSD) are driven by biological, learning, and cognitive models that have shaped current treatments of the disorder. The strong influence of these models has resulted in a relative neglect of social mechanisms that can influence traumatic stress. There is abundant evidence from experimental, observational, and clinical studies that social factors can moderate many of the mechanisms articulated in prevailing models of PTSD. In this review it is proposed that attachment theory provides a useful framework to complement existing models of PTSD because it provides explanatory value for social factors can interact with biological, learning, and cognitive processes that shape traumatic stress response. The review provides an overview of attachment theory in the context of traumatic stress, outlines the evidence for how attachment factors can moderate stress responses and PTSD, and considers how harnessing attachment processes may augment recovery from and treatment of PTSD. This review emphasizes that rather than conceptualizing attachment theory as an independent theory of traumatic stress, there is much to gain by integrating attachment mechanisms into existing models of PTSD to accommodate the interactions between cognitive, biological, and attachment processes.

Abstract
Social attachment systems are disrupted for refugees through trauma and forced displacement. This study tested how the attachment system mitigates neural responses to threat in refugees with posttraumatic stress disorder (PTSD). Refugees with PTSD (N = 28) and refugee trauma-exposed controls (N = 22) viewed threat-related stimuli primed by attachment cues during a functional magnetic resonance imaging scan. Group differences and the moderating effects of avoidant or anxious attachment style and grief related to separation from family on brain activity and connectivity patterns were examined. Separation grief was associated with increased amygdala but decreased ventromedial prefrontal cortical (VMPFC) activity to the attachment prime and decreased VMPFC and hippocampal activity to attachment primed threat in the PTSD (vs trauma-exposed control) group. Avoidant attachment style was connected with increased dorsal frontoparietal attention regional activity to attachment prime cues in the PTSD group. Anxious attachment style was associated with reduced left amygdala connectivity with left medial prefrontal regions to attachment primed threat in the PTSD group. Separation grief appears to reduce attachment buffering of threat reactivity in refugees with PTSD, while avoidant and anxious attachment style modulated attentional and prefrontal regulatory mechanisms in PTSD, respectively. Considering social attachments in refugees could be important to post-trauma recovery, based within changes in key emotion regulation brain systems.

Abstract
BACKGROUND AND OBJECTIVES Attachment theory suggests that internal working models developed from early experiences with attachment figures biases cognitive appraisals a person makes of themselves and others. The current paper investigates whether attachment-related interpretative biases can be altered using Cognitive Bias Modification (CBM-I). METHODS Eighty anxiously attached participants were randomly assigned to receive either secure or insecure CBM-I training. To measure training effects on attachment-related interpretation bias, participants read scenarios involving attachment figures whereby the availability of the attachment figure was undetermined, followed by test sentences that assigned an attachment-secure or -insecure interpretation to the situations. Participants rated the similarity of these sentences to the previously read ambiguous situations. RESULTS Participants who received secure CBM-I training ascribed higher similarity ratings to secure sentence interpretations of ambiguous scenarios compared to insecure sentence interpretations. Attachment anxiety increased after CBM-I training for those who received insecure training, but did not differ for those who received secure training. LIMITATIONS This study was limited to healthy participants and did not include clinical participants. These findings need to be replicated by assessing the effects of CBM-I over an extended period. CONCLUSIONS CBM-I training may provide a viable means of modulating attachment anxiety. If validated with more potent strategies for secure attachment training, this approach could have significant implications for the treatment of affective disorders characterized by insecure attachments.

Abstract
BACKGROUND Recent studies have found that attachment security primes can inhibit fear acquisition. This current study aimed to examine whether a brief imaginal prime of one's attachment figure could impact on fear consolidation. METHODS A total of 75 participants underwent fear conditioning on Day 1 and fear recall was tested on Day 2. Immediately following conditioning, half the participants were instructed to imagine an attachment figure while the other half imagined a nonattachment positive situation. Fear-potentiated startle and subjective expectancy of shock ratings were used as the measures of fear learning across trials. RESULTS The attachment group showed significantly lower levels of fear recall on Day 2 at both physiological and subjective levels. Furthermore, this effect was moderated by attachment anxiety, such that it was greatest for individuals who were securely attached. CONCLUSIONS These findings suggest that attachment relationships are protective during the consolidation of fear memories, and may have implications for how social attachments may impact how anxiety disorders can develop.

Abstract
BACKGROUND Dyads receiving palliative care for advanced heart failure are at risk for the loss of feeling safe, experienced as a fractured sense of coherence, discontinuity in sense of self and relationships, and strained social connections and altered roles. However, few theory-based interventions have addressed feeling safe in this vulnerable population. PURPOSE The purpose of this article is to describe the development of the Nostalgic Remembering Intervention to strengthen feeling safe and promote adaptive physiological and psychological regulation in dyads receiving palliative care for heart failure. CONCLUSIONS Systematic intervention development is essential to understand what, for whom, why, and how an intervention works in producing outcomes. Program theory provided a systematic approach to the development of the Nostalgic Remembering Intervention, including conceptualization of the problem targeted by the intervention, specification of critical inputs and conditions that operationalize the intervention, and understanding the mediating processes leading to expected outcomes. CLINICAL IMPLICATIONS Creating a foundation for cardiovascular nursing research and practice requires continued, systematic development of theory-based interventions to best meet the needs of dyads receiving palliative care for heart failure. The development of the Nostalgic Remembering Intervention to strengthen feeling safe in dyads provides a novel and relevant approach.

Abstract
To further understand protective mechanisms to prevent post-traumatic stress disorder or assist recovery from psychological trauma, this study investigated whether pharmacological and psychological activation of a secure attachment representation elicits higher felt-security and a related response pattern of reduced physiological arousal and increased parasympathetic activation; and whether it protects individuals from developing intrusions and experiencing distress in the week following exposure to a trauma film. Using a double-blind, experimental mixed factorial design, 101 volunteers received either oxytocin or placebo and either secure attachment or neutral priming before watching a trauma film. We measured felt security as an indicator of the strength of activation of a secure attachment representation, skin conductance and heart rate as indicators of physiological arousal, and high frequency heart rate variability as an indicator of parasympathetic activation during the priming and the film. Participants then completed a seven-day intrusion diary. Secure attachment priming, but not oxytocin administration or the combination of both, was associated with reduced physiological arousal and increased parasympathetic activity during priming. Although secure attachment priming was not related to the absolute number of intrusions or to less perceived distress or physiological arousal during the trauma film, it was associated with lower intrusion-related distress in the 7-days post-testing. Our findings extend previous research that suggests the importance of interventions that address intrusion-related distress for recovery from trauma, and suggest a promising role for secure attachment priming in trauma-focused psychological therapies. We contribute to the growing literature that finds that higher subjective distress during a trauma is associated with higher intrusion-related distress. We discuss theoretical implications and possible mechanisms through which secure attachment priming may exert potential beneficial effects.

Abstract
Recognizing the biopsychosocial dimensions of chronic medical conditions in children and preparing them to adapt to medical processes is one of the most significant issues in the field of health psychology. The aim of this study was to measure heart rate variability and cognitive abilities based on attachment style in children with chronic medical conditions. To this end, 45 children aged 12-15 years who had received a diagnosis of a chronic medical disease and were matched with the inclusion/exclusion criteria, were entered the study using available sampling method. These children were assigned to three groups of secure, avoidance and anxiety attachment style based on the Collins and Reid Attachment Scale. These groups had been demographically homogeneous. Then heart rate variability and cognitive abilities were measured. One-way ANOVA results showed a significant difference between the three groups in the heart rate variability and cognitive abilities. Post hoc test showed that children with secure attachment style had higher efficiency in heart rate variability and cognitive abilities. These results indicate that attachment style is one of the factors influencing the health status of children with chronic medical illness. These findings highlight the importance of paying attention to psychological factors, especially attachment and its role in the health status of children with chronic medical conditions.

Abstract
Thinking of attachment figures can potentially impact acquisition and extinction of fear memories. In this study, 50 participants underwent a fear conditioning and extinction paradigm. Half the participants thought about a supportive attachment figure and half thought about a non-attachment positive experience prior to the fear conditioning. All participants then underwent a differential fear conditioning and fear extinction paradigm, and returned 2 days later for an extinction recall task. Fear-potentiated startle and subjective expectancy of shock ratings were measured as the primary indicators of fear learning across trials. The attachment prime significantly reduced the acquisition of fear-potentiated startle, and this lower level of fear was maintained at the extinction recall task. These results demonstrate that attachment primes can modulate the acquisition of conditioned fear. These findings provide preliminary evidence for the protective nature of attachment relationships at times that are characterized by fear learning.

Abstract
Attachment theory suggests that at all stages of life, regular contact with attachment figures fosters a fundamental sense of safety and security. Yet an increasing number of romantic couples undergo prolonged physical separations from one another, rangingfrom several weeks to several years, and involving widely varying opportunities for communication and contact. This article reviews contemporary research on the implications of such separations for attachment-related dynamics, including relationship satisfaction and psychobiological attunement between partners. Recent technological innovations in computer-mediated contact (such as video calls and electronic messaging) and their capacity to `stand in' for direct physical contact are also discussed, along with directions for future research in the diverse psychobiological mechanisms underlying attachment formation and functioning at different stages of life and in different contexts.

Abstract
BACKGROUND The aim of this study was to assess the potential effectiveness of secure attachment priming in outpatients with depressive disorders. METHODS Forty-eight participants engaged in secure attachment priming or neutral priming in the laboratory (Time 1), after which they received three daily consecutive primes via text message (Times 2-4), aimed at maintaining the effects from Time 1. A follow-up one day later (Time 5) was also included. Dependent measures were assessed at Times 1, 4 and 5. RESULTS Participants in the secure attachment priming condition experienced higher felt-security than the control group at all time-points, indicating that the felt-security benefit was maintained through repeated priming. Secure priming had a greater impact on reducing symptoms of anxiety and depression in comparison to the control prime, though the differences were only significant at Time 4. LIMITATIONS The moderate sample size limited our statistical power. CONCLUSIONS This study was the first experiment using repeated secure attachment priming within a clinical sample. Our findings have potential clinical implications; security priming could be used alongside other treatments to improve outcome. Recommendations for further research are discussed.

Abstract
Although activating mental representations of attachment figures is beneficial for psychological health, there is a paucity of knowledge of the underlying mechanisms. We investigated how priming attachment figures may modulate parasympathetic stress response. Participants (N = 62) with varying degrees of attachment security underwent a cold pressor test, and then imagined an attachment or non-attachment figure. Heart rate variability was assessed throughout the study. Participants with low avoidant attachment levels displayed less negative affect and greater heart rate variability following the attachment prime than those who imagined the non-attachment prime. This beneficial effect of attachment priming was not observed in participants with high avoidant attachment levels. These findings highlight that activating attachment representations can enhance the parasympathetic stress response in people with secure attachment styles, and provides one explanation for the psychological benefits of attachment proximity.

Abstract
In this study, the authors explored whether attachment insecurity moderates the effects of adverse childhood experiences on stress reactivity in the context of borderline personality disorder (BPD). Participants were 113 women (39 with BPD, 15 with some BPD criteria present, 59 without any BPD symptoms) who participated in the Trier Social Stress Test. Saliva samples were collected before and after the stressor and assayed for salivary alpha-amylase (sAA) and cortisol. Adverse childhood experiences were measured using the Childhood Trauma Questionnaire, and attachment by the Experiences in Close Relationships-Revised questionnaire. Results revealed that attachment avoidance and a combination of more adverse childhood experiences and attachment insecurity resulted in higher sAA levels and differences in reactivity to the stressor. Interactions between attachment anxiety and adverse childhood experiences were related to blunted cortisol reactivity. The results suggest that the influence of adverse childhood experiences on stress regulation in BPD may be moderated by attachment-related regulatory processes.

Abstract
BACKGROUND Refugees can suffer many experiences that threaten their trust in others. Although models of refugee mental health have postulated that attachment securities may be damaged by refugee experiences, this has yet to be empirically tested. This study aimed to understand the relationship between the nature of traumatic experiences sustained by refugees and attachment styles. METHOD In a cross-sectional study, treatment-seeking refugees (N = 134) were assessed for traumatic exposure using the Harvard Trauma Questionnaire and Posttraumatic Diagnostic Scale. Attachment style was assessed using the Experiences in Close Relationship Scale. RESULTS Whereas gender and severity of interpersonal traumatic events predicted avoidant attachment style (accounting for 11% of the variance), neither these factors nor non-interpersonal trauma predicted anxious attachment. CONCLUSIONS Exposure to interpersonal traumatic events, including torture, is associated with enduring avoidant attachment tendencies in refugees. This finding accords with attachment theories that prior adverse interpersonal experiences can undermine secure attachment systems, and may promote avoidance of attachment seeking. This finding may point to an important process maintaining poor psychological health in refugees affected by interpersonal trauma.

Abstract
Emotional memories, and especially intrusive memories, are a common feature of many psychological disorders, and are overconsolidated by stress. Attachment theory posits that activation of mental representations of attachment figures can reduce stress and boost coping. This study tested the proposition that attachment activation would reduce consolidation of emotional and intrusive memories. Sixty-seven undergraduate students viewed subliminal presentations of traumatic and neutral images, which were preceded by subliminal presentations of either attachment-related images or non-attachment-related images; free recall and intrusive memories were assessed two days later. Participants with low avoidant attachment tendencies who received the attachment primes recalled fewer memories and reported fewer intrusions than those who received the non-attachment primes. Unexpectedly, those with high anxious attachment tendencies reported fewer memories. These findings generally accord with attachment theory, and suggest that consolidation of emotional memories can be moderated by activation of attachment representations.

Abstract
Short-term separation from close family members during a disaster is a highly salient event for those involved. Yet, its subsequent impact on mental health has received little empirical attention. One relevant factor may be attachment style, which influences patterns of support-seeking under threatening conditions. Individuals (N = 914) affected by the 2009 Victorian bushfires in southeastern Australia were assessed for disaster experiences, depression, posttraumatic stress disorder (PTSD) symptoms, and attachment style 3-4 years after the fires. Using multigroup structural equation modelling, individuals who reported separation from close family members during the bushfires (n = 471) were compared to those who reported no separation (n = 443). Cross-sectional results indicated that separated individuals had higher levels of PTSD symptoms. Furthermore, attachment anxiety was more strongly positively associated with depression among separated (b = 0.62) versus not separated individuals (b = 0.32). Unexpectedly, among separated individuals, attachment avoidance had a statistically weaker association with depression (b = 0.17 vs. b = 0.35) and with PTSD symptoms (b = 0.06 vs. b = 0.22). These results suggest that attachment anxiety amplifies a negative reaction to separation; meanwhile, for avoidant individuals, separation in times of danger may facilitate defensive cognitive processes.

Abstract
The extent to which we engage with our social world has been central to our survival as a species and, accordingly, is relevant to how we cope with trauma and adversity. This review summarises current knowledge about the importance of social connections from an evolutionary perspective, as well as integrating this with a discussion of prevailing attachment theories. Experimental research supporting the potential benefit of attachments for managing adversity are presented, along with a review of how these benefits are moderated by individual differences in attachment style. The potential impact of trauma on attachment systems, and the manner in which this can compound trauma stress is discussed. Finally, a broader overview of social network analysis is introduced and it is proposed that a more sociocentric framework of trauma response would promote a fuller understanding of how social processes moderate trauma response.
