Moral injury appraisals and complex PTSD in refugees: A longitudinal study.

OBJECTIVE: Refugees show elevated rates of complex posttraumatic stress disorder (CPTSD). However, relatively little is known regarding the psychological mechanisms that underlie the association between exposure to potentially traumatic events (PTEs) and CPTSD following exposure to war, persecution and displacement. In this study, we investigated the potential mediating role of moral injury appraisals (cognitive appraisals regarding the experience and consequences of morally transgressive events) in the association between PTE exposure, posttraumatic stress disorder (PTSD), and disturbances in self-organization (DSO) symptoms. METHOD: Participants were 889 refugees from Arabic-, Farsi-, Tamil-, and English-speaking backgrounds who completed an online survey in their own language at two time points 12 months apart. We assessed PTE exposure, moral injury-other appraisals (appraising moral transgressions as enacted by others), moral injury-self appraisals (appraising moral transgressions as enacted by the self), PTSD symptoms, and DSO symptoms. RESULTS: Longitudinal structural equation modeling indicated that moral injury-other appraisals mediated the association between PTE exposure and both PTSD and DSO symptoms. In contrast, moral injury-self appraisals only mediated the association between PTE exposure and DSO symptoms. CONCLUSIONS: Findings highlight the role of moral injury appraisals in exacerbating traditional PTSD symptoms, as well as the broader symptoms characteristic of CPTSD. Further, results indicate that specific types of moral injury appraisals (relating to one's own and others' perceived moral transgressions) may lead to differential psychological reactions, raising important implications for clinical practice.

Self-construal modulates default mode network connectivity in refugees with PTSD.

BACKGROUND: While self-construal and posttraumatic stress disorder (PTSD) are independently associated with altered self-referential processes and underlying default mode network (DMN) functioning, no study has examined how self-construal affects DMN connectivity in PTSD. METHODS: A final sample of 93 refugee participants (48 with DSM-5 PTSD or sub-syndromal PTSD and 45 matched trauma-exposed controls) completed a 5-minute resting state fMRI scan to enable the observation of connectivity in the DMN and other core networks. A self-construal index was calculated by substracting scores on the collectivistic and individualistic sub-scales of the Self Construal Scale. RESULTS: Independent components analysis identified 9 active networks-of-interest, and functional network connectivity was determined. A significant interaction effect between PTSD and self-construal index was observed in the anterior ventromedial DMN, with spatial maps localizing this to the left ventromedial prefrontal cortex (vmPFC), extending to the ventral anterior cingulate cortex. This effect revealed that connectivity in the vMPFC showed greater reductions in those with PTSD with higher levels of collectivistic self-construal. LIMITATIONS: This is an observational study and causality cannot be assumed. The specialized sample of refugees means that the findings may not generalize to other trauma-exposed populations. CONCLUSIONS: Such a finding indicates that self-construal may shape the core neural architecture of PTSD, given that functional disruptions to the vmPFC underpin the core mechanisms of extinction learning, emotion dysregulation and self-referential processing in PTSD. Results have important implications for understanding the universality of neural disturbances in PTSD, and suggest that self-construal could be an important consideration in the assessment and treatment of post-traumatic stress reactions.

Cultural differences in appraisals of control and posttraumatic stress disorder symptoms.

Background: Appraisals are central to posttraumatic stress disorder (PTSD). Yet, few studies have examined how culture influences the associations between different types of trauma-related appraisals and PTSD symptoms.Objective: This study investigated cultural influences on appraisals of control and their associations with PTSD symptoms.Method: European Australian (n = 140, Mage = 35.80, SD = 12.44; 21 men, 97 women, 20 gender diverse/prefer not to report) and Chinese Australian (n = 129, Mage = 30.16, SD = 8.93, 21 men, 97 women, 20 gender diverse/prefer not to report) trauma survivors completed measures of appraisals, cultural values, and PTSD symptoms.Results: Findings showed that the Chinese Australian group was associated with greater Chinese cultural beliefs about adversity (i.e. emphasizing the value of adversity and people's ability to overcome adversity) and fewer fatalism appraisals (i.e. appraising one's destiny as externally determined), which in turn were atemporally associated with fewer PTSD symptoms; these atemporal indirect associations were moderated by self-construal and holistic thinking. The Chinese Australian group also reported fewer secondary control appraisals (i.e. attempts to change aspects of the self and accept current circumstances), which were atemporally associated with greater PTSD symptoms. In contrast, the European Australian group was associated with fewer primary control appraisals (i.e. perceived ability to personally change or control a situation), which were atemporally associated with greater PTSD symptoms.Conclusion: These findings highlight the importance of considering the influence of culture on appraisals in PTSD. However, it must be noted that causal relationships cannot be inferred from cross-sectional mediation analyses and thus, future longitudinal research is needed.

Chinese Australian trauma survivors were associated with greater reporting of Chinese cultural beliefs about adversity and fewer fatalism appraisals, which were associated with fewer PTSD symptoms. These associations were moderated by a trauma survivor's self-construal and level of holistic thinking.Chinese Australian trauma survivors reported fewer secondary control appraisals, which were associated with greater PTSD symptoms.European Australian trauma survivors were associated with fewer primary control appraisals, which were associated with greater PTSD symptoms.

Opponent intrinsic brain network connectivity profiles associated with posttraumatic fear and dysphoria symptoms in trauma-exposed refugees.

OBJECTIVE: Resting-state functional magnetic resonance imaging (rsfMRI) studies report functional alterations in the connectivity between intrinsic brain networks in posttraumatic stress disorder (PTSD), but PTSD heterogeneity is rarely considered. Evidence points to fear (e.g., reexperiencing) and dysphoria (e.g., withdrawal) symptom factors as important in PTSD presentations, including relating to variable emotion dysregulation patterns. This study, therefore, tested how fear and dysphoria posttraumatic symptoms were differentially associated with core network connectivity and emotion dysregulation behaviors in a large group of trauma-exposed refugees. METHOD: A final sample of 77 trauma-exposed participants completed a rsfMRI scan. Independent component analysis identified active networks and functional network connectivity (FNC) between networks was assessed. Fear and dysphoria posttraumatic symptoms were partially correlated with FNCs, and linear regression models examined relationships with self-reported difficulties in emotion regulation. RESULTS: Twenty-three active networks were identified, eight being in the networks of interest (p < .05 false discovery rate-corrected). Fear and dysphoria symptoms were specifically related to connectivity patterns between two subnetworks of the default mode network (DMN). Fear symptoms were negatively associated with anterior dorsomedial DMN (admDMN) and temporoparietal DMN (tpDMN) connectivity; whereas dysphoria symptoms were positively associated with admDMN-tpDMN connectivity. Additionally, admDMN-tpDMN connectivity was positively predicted by goal-directed emotion dysregulation but negatively predicted by poor emotional clarity. CONCLUSIONS: Fear and dysphoria posttraumatic symptoms showed opponent associations with admDMN and tpDMN connectivity, potentially reflecting patterns of under- and overemotion dysregulation associated with these symptom profiles respectively. Findings highlight the importance of considering posttraumatic heterogeneity when constructing neural models of PTSD. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Refugee visa insecurity disrupts the brain's default mode network.

BACKGROUND: Research has largely focused on the psychological consequences of refugee trauma exposure, but refugees living with visa insecurity face an uncertain future that also adversely affects psychological functioning and self-determination. OBJECTIVE: This study aimed to examine how refugee visa insecurity affects the functional brain. METHOD: We measured resting state brain activity via fMRI in 47 refugees with insecure visas (i.e. temporary visa status) and 52 refugees with secure visas (i.e. permanent visa status) residing in Australia, matched on key demographic, trauma exposure and psychopathology. Data analysis comprised independent components analysis to identify active networks and dynamic functional causal modelling tested visa security group differences in network connectivity. RESULTS: We found that visa insecurity specifically affected sub-systems within the default mode network (DMN) - an intrinsic network subserving self-referential processes and mental simulations about the future. The insecure visa group showed less spectral power in the low frequency band in the anterior ventromedial DMN, and reduced activity in the posterior frontal DMN, compared to the secure visa group. Using functional dynamic causal modelling, we observed positive coupling between the anterior and posterior midline DMN hubs in the secure visa group, while the insecure visa group displayed negative coupling that correlated with self-reported fear of future deportation. CONCLUSIONS: Living with visa-related uncertainty appears to undermine synchrony between anterior-posterior midline components of the DMN responsible for governing the construction of the self and making mental representations of the future. This could represent a neural signature of refugee visa insecurity, which is marked by a perception of living in limbo and a truncated sense of the future.

Refugee visa insecurity disrupts default mode network (DMN) connectivity ­ a core network that supports the internal construction of the self.Refugees living with insecure visa status showed decreased connectivity in the DMN and more negative coupling between midline anterior­posterior hubs of the DMN, compared to refugees living with secure visas.Diminished DMN connectivity may represent a neural basis for the psychological effects of refugee visa insecurity, which is associated with prolonged uncertainty regarding the future self and increased risk for psychological distress.

The mental health effects of changing from insecure to secure visas for refugees.

OBJECTIVE: In response to growing numbers of refugees worldwide, host governments are increasingly implementing temporary protection policies; however, little is known regarding the mental health impact of these policies. This online longitudinal study investigated whether refugees who transitioned from low visa security (e.g. short-term transient visas) to medium (e.g. temporary protection visas) or high visa (e.g. permanent visas) security showed changes in depression symptoms, social difficulties and immigration-related fears. METHODS: Participants were 1,201 refugees and asylum-seekers from Arabic, Farsi, Tamil or English-speaking backgrounds. Study variables were measured prior to and after change in visa status (6 months apart). RESULTS: Refugees who transitioned from low to medium security visas showed reduced immigration-related fear (B = -0.09, 95% confidence interval = -0.29 to -0.06), but no change in depression symptoms or social difficulties compared to those who retained low visa security. Refugees who transitioned from low to high security visas showed reduced depression symptoms (B = -0.02, 95% confidence interval = -0.04 to -0.01), social difficulties (B = -0.04, 95% confidence interval = -0.05 to -0.01) and immigration-related fear (B = -0.03, 95% confidence interval = -0.06 to -0.01) compared to those who retained low visa security. CONCLUSION: Findings indicate that the increased security afforded by temporary protection policies (vs short-term transient visas) did not translate into improved mental health and social outcomes for refugees. In contrast, permanent protection was associated with significant improvements in psychological and social functioning. These results have important policy implications for countries who have committed to protect and facilitate improved mental health among refugees.

The impact of COVID-19 stressors on refugee mental health and well-being in the context of sustained displacement.

Refugees and asylum seekers in contexts of sustained displacement represent particularly vulnerable communities during the COVID-19 pandemic. The aim of this study was to identify profiles of COVID-19 stressors in refugees in a transit context (i.e., Indonesia) and examine the relationship between these profiles of stressors and mental health and well-being. Participants in this study included 913 refugees and asylum seekers living in Indonesia. The study was completed online in five languages (i.e., Arabic, Dari, Farsi, Somali, and English). A latent class analysis was implemented with 12 COVID-19 stressors representing indicator variables to identify profiles of COVID-19-related stressors experienced. Associations between COVID-19 classes and mental health (posttraumatic stress disorder, depression, anxiety) and well-being (physical and mental) outcomes were investigated. A five-class solution was identified as providing the best fit to the data as follows: (a) a high-COVID stressors class (18.1%), (b) a high access stressors class (13.2%), (c) an infection stressors class (22.7%), (d) a moderate access stressors class (23.1%), and (e) a low-COVID stressors class (22.8%). Membership of all classes reporting at least moderate levels of COVID-19 stressors was associated with greater mental health difficulties and lower physical and mental well-being than the low-COVID stressors class. Results indicated that the severity and type of stressors differed between groups suggesting heterogeneous experiences of the pandemic. Classes also differed according to contextual and social factors such as negative social support, language, and geographic area. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Context, coping, and mental health in refugees living in protracted displacement.

There is currently an unprecedented number of forcibly displaced people worldwide. Little is known, however, about how external stressors and internal coping strategies intersect to influence mental health in displaced refugees, particularly whether specific types of coping strategies are more or less effective across different levels of external stress. This study aimed to understand whether positive and negative internal coping strategies were differentially associated with mental health across high and low levels of external stressors in displaced refugees. Participants were 1,216 refugees living in Indonesia who completed an online survey indexing demographic characteristics, exposure to ongoing stressors, positive psychological coping strategies (i.e., cognitive flexibility, self-efficacy, and hope), negative psychological coping strategies (i.e., rumination and intolerance of uncertainty), psychological symptoms (i.e., posttraumatic stress disorder, depression, and anxiety) and mental health-related quality of life. Participants (27.3% female, Mage = 30.52 years) were from Arabic-, Farsi-, Tamil-, Somali-, Dari-, and English-speaking backgrounds. Results of latent moderated structural equation modeling indicated that the association between negative psychological coping strategies and poorer mental health was stronger at higher levels of stress, whereas the association between positive psychological coping strategies and better quality of life was stronger at lower levels of stress. These findings provide evidence in support of tailored approaches that integrate interventions addressing external stressors and internal coping strategies to support positive mental health and enhanced quality of life in displaced refugees.

Impact of displacement context on psychological distress in refugees resettled in Australia: a longitudinal population-based study.

AIMS: Refugees typically spend years in a state of protracted displacement prior to permanent resettlement. Little is known about how various prior displacement contexts influence long-term mental health in resettled refugees. In this study, we aimed to determine whether having lived in refugee camps v. community settings prior to resettlement impacted the course of refugees' psychological distress over the 4 years following arrival in Australia. METHODS: Participants were 1887 refugees who had taken part in the Building a New Life in Australia study, which comprised of five annual face-to-face or telephone surveys from the year of first arrival in Australia. RESULTS: Latent growth curve modelling revealed that refugees who had lived in camps showed greater initial psychological distress (as indexed by the K6) and faster decreases in psychological distress in the 4 years after resettling in Australia, compared to those who had lived in community settings. Investigation of refugee camp characteristics revealed that poorer access to services in camps was associated with greater initial distress after resettlement, and greater ability to meet one's basic needs in camps was associated with faster decreases in psychological distress over time. CONCLUSIONS: These findings highlight the importance of the displacement context in influencing the course of post-resettlement mental health. Increasing available services and meeting basic needs in the displacement environment may promote better mental health outcomes in resettled refugees.

Cognitive mechanisms underlying the association between trauma exposure, mental health and social engagement in refugees: A longitudinal investigation.

BACKGROUNDS: Refugees and asylum-seekers are at heightened risk for developing psychological symptoms following exposure to trauma and displacement. Despite this, relatively little is known about the cognitive mechanisms that underlie common mental disorders in refugees. METHODS: In this study, we investigated the associations between self-efficacy, beliefs about others (relating to benevolence and trust) and psychological and social outcomes in 1079 refugees from Arabic, Farsi, Tamil or English-speaking backgrounds who were residing in Australia. Participants completed an online survey assessing exposure to potentially traumatic events (PTEs), at baseline (T1), and self-efficacy, beliefs about others, PTSD symptoms, depression symptoms, anger and social engagement at baseline (T1) and six months later (T2). RESULTS: A path analysis revealed that greater PTE exposure was associated with lower self-efficacy and lower positive beliefs about others at T1. Self-efficacy at T1 was negatively associated with depression and anger at T2, while positive beliefs about others at T1 were positively associated with social engagement and greater depression symptoms at T2. LIMITATIONS: Limitations of this study included the fact that the study sample was not necessarily representative of the broader refugee population, and in particular may have overrepresented those with higher education levels. CONCLUSIONS: Findings point to the critical role that cognitive variables play in the maintenance of psychological symptoms in forcibly displaced persons, and highlight the importance of targeting these in psychological interventions to promote positive posttraumatic mental health.

Understanding the effects of being separated from family on refugees in Australia: a qualitative study.

OBJECTIVE: To understand the impact of family separation on refugees living in Australia. METHOD: Thirteen participants with a refugee background and experiencing separation from family participated in a semi-structured qualitative interview. Interviews were coded and a thematic analysis was conducted using NVivo software. RESULTS: Identified themes were organised under four domains. Domain 1 focused on the personal impact of family separation. Themes were the effects on mental health and functioning, driven by incessant worrying about the safety of family and the absence of key attachment figures, the specific effects of having missing family, alterations to self-identity and family dynamics. Domain 2 focused on themes relating to actions taken to find missing family, connect or reunite with separated family. Domain 3 highlighted the coping strategies, support mechanisms and protective factors used by participants. Domain 4 identified core beliefs about the importance of family unity, focusing on security, settlement and a happy future. CONCLUSIONS: Family separation has an enduring effect on the wellbeing of refugees, with key pathways being ongoing fear and insecurity, disrupted social attachments and identity shifts in relation to the future self. IMPLICATIONS FOR PUBLIC HEALTH: Refugees separated from or missing family struggle with ongoing stress and adjustment issues.

Torture exposure and the functional brain: investigating disruptions to intrinsic network connectivity using resting state fMRI.

Torture has profound psychological and physiological consequences for survivors. While some brain structures and functions appear altered in torture survivors, it is unclear how torture exposure influences functional connectivity within and between core intrinsic brain networks. In this study, 37 torture survivors (TS) and 62 non-torture survivors (NTS) participated in a resting-state fMRI scan. Data-driven independent components analysis identified active intrinsic networks. Group differences in functional connectivity in the default mode network (DMN), salience network (SN) and central executive network (CEN) of the triple network model, as well any prefrontal network, were examined while controlling for PTSD symptoms and exposure to other potentially traumatic events. The analysis identified 25 networks; eight comprised our networks of interest. Within-network group differences were observed in the left CEN (lCEN), where the TS group showed less spectral power in the low-frequency band. Differential internetwork dynamic connectivity patterns were observed, where the TS group showed stronger positive coupling between the lCEN and anterior dorsomedial and ventromedial DMN, and stronger negative coupling between a lateral frontal network and the lCEN and anterior dorsomedial DMN (when contrasted with the NTS group). Group differences were not attributed to torture severity or dissociative symptoms. Torture survivors showed disrupted dynamic functional connectivity between a laterally-aligned lCEN that serves top-down control functions over external processes and the midline DMN that underpins internal self-referential processes, which may be an adaptive response to mitigate the worst effects of the torture experience. This study provides a critical step in mapping the neural signature of torture exposure to guide treatment development and selection.

The longitudinal association between moral injury appraisals and psychological outcomes in refugees.

BACKGROUND: Refugees report a diverse array of psychological responses following persecution and displacement. Little is known, however, regarding the mechanisms that underlie differential psychological reactions in refugees. This study investigated the longitudinal impact of negative moral appraisals about one's own actions [i.e. moral injury-self (MI-self) appraisals] and others' actions [i.e. moral injury-other (MI-others) appraisals] on a variety of psychological symptoms over a period of 6 months. METHODS: Participants were 1085 Arabic, Farsi, Tamil, or English-speaking refugees who completed a survey at baseline and 6 months later either on-line or via pen-and-paper. The survey indexed demographic factors, exposure to potentially traumatic events (PTEs), exposure to ongoing stressors, MI-other appraisals, MI-self appraisals, re-experiencing and arousal symptoms, and feelings of sadness, anger and shame. RESULTS: Findings indicated that, after controlling for demographics, PTE exposure and ongoing stressors, MI-other appraisals predicted increased re-experiencing and hyperarousal symptoms, and feelings of sadness and shame. MI-self appraisals predicted decreased feelings of shame, and decreased re-experiencing symptoms. In contrast, psychological symptoms at baseline did not as strongly influence MI appraisals 6 months later. CONCLUSIONS: These findings highlight the important role that cognitive appraisals of adverse events play in the longitudinal course of psychological symptoms. These results thus have important implications for the development of tailored psychological interventions to alleviate the mental health burden held by refugees.

Course and predictors of posttraumatic stress and depression longitudinal symptom profiles in refugees: A latent transition model.

Exposure to potentially traumatic events and post-migration living difficulties (PMLDs) may explain the high rates of posttraumatic stress disorder (PTSD) and depression in resettled refugees. Latent class analyses (LCAs) in refugees have identified subgroups that differ in symptom profiles of PTSD and comorbid symptoms. However, knowledge on longitudinal symptom profiles in refugees is sparse. Examining longitudinal PTSD and depression symptom profiles could provide information on risk factors underlying worsening of symptoms post-resettlement. Self-rated PTSD (Posttraumatic Diagnostic Scale) and depression (Patient Health Questionnaire-9) symptoms were assessed among 613 refugees who had resettled in Australia up to two years previously (W1) and at 6 months follow-up (W2). PTSD and depression symptom profiles were identified using LCAs for W1 and W2 separately. Latent transition analysis was used to examine (predictors of) changes in symptom profiles, including gender, age, trauma exposure, and PMLDs. Four classes were identified that were consistent across timepoints: a No symptoms (W1 61%; W2 68%), Low PTSD/Moderate depression (W1 16%; W2 10%), Moderate PTSD/depression (W1 16%; W2 14%), and High symptoms class (W1 7%; W2 7%). Higher levels of problems with PMLDs, including being discrimination and family separation, predicted movements out of the No symptom class at W1 to classes with psychopathology at W2. To conclude, most participants did not develop PTSD or depression symptoms. The risk of developing these symptoms seems higher when problems with interpersonal PMLDs increased, pointing to the need for considering these stressors when addressing the mental health needs in this population.

Factors associated with COVID-19 vaccine hesitancy amongst refugees in Australia.

Background: Refugees may be especially vulnerable to the adverse effects of COVID-19. Therefore it is critical that refugee communities are supported to access COVID-19 vaccines and for public health responses to address vaccine hesitancy. Objective: To investigate the key demographic factors, barriers and attitudes associated with vaccine hesitancy in a community sample of refugees. Method: Participants in the Refugee Adjustment Study, a cohort of refugees living in Australia, were invited to complete a survey about their COVID-19 vaccine intentions, barriers to access and attitudes relating to the vaccine. Results: Of the 516 participants, 88% were unvaccinated and 28.1% were classed as vaccine hesitant. Key predictors of vaccine hesitancy were younger age, information and trust barriers, lower logistical barriers, and attitudes relating to low control and risk posed by COVID-19. Conclusions: Findings suggest that public health strategies need to address trust, control and risk perception attitudes to increase COVID-19 vaccine uptake in resettled refugee communities.

Antecedentes: Los refugiados pueden ser especialmente vulnerables a los efectos adversos del COVID-19. Por lo tanto, es fundamental que las comunidades de refugiados reciban apoyo para acceder a las vacunas COVID-19 y para que las respuestas de salud pública aborden la indecisión ante las vacunas.Objetivo: Investigar los factores demográficos clave, las barreras y las actitudes asociadas con la indecisión ante las vacunas en una muestra comunitaria de refugiados.Método: Se invitó a los participantes en el Estudio de Adaptación de Refugiados, una cohorte de refugiados que viven en Australia, a completar una encuesta sobre sus intenciones de vacunarse contra el COVID-19, barreras de acceso y actitudes relacionadas con la vacuna.Resultados: De los 516 participantes, el 88% no estaban vacunados y el 28,1% se clasificaron como reacios a vacunarse. Los predictores clave de la vacilación a la vacuna fueron menor edad, las barreras en información y confianza, menores barreras logísticas y las actitudes relacionadas con bajo control y el riesgo que plantea el COVID-19.Conclusiones: Los hallazgos sugieren que las estrategias de salud pública deben abordar las actitudes de confianza, control y percepción del riesgo para aumentar la aceptación de la vacuna COVID-19 en las comunidades de refugiados reasentados.

Secure attachment priming protects against relapse of fear in Young adults.

Previous studies have shown that activating the attachment system attenuates fear learning. This study aimed to explore whether attachment priming can also impact on fear extinction processes, which underpin the management of anxiety disorders. In this study, 81 participants underwent a standard fear conditioning and extinction protocol on day 1 and returned 24 h later for an extinction recall and reinstatement test. Half the participants were primed to imagine their closest attachment figure prior to undergoing extinction training, while the other half were instructed to imagine a positive situation. Fear-potentiated startle and subjective expectancies of shock were measured as the primary indicators of fear. Attachment priming led to less relapse during the reinstatement test at the physiological but not subjective levels. These findings have translational potential to imply that activating awareness of attachment figures might augment long-term safety memories acquired in existing treatments to reduce relapse of fear.

The association between COVID-19 related stressors and mental health in refugees living in Australia.

BACKGROUND: Refugees may be particularly vulnerable to the adverse effects of the COVID-19 pandemic on mental health due to their traumatic pasts and the challenges of the postmigration environment. OBJECTIVE: To evaluate the prevalence of COVID-19 related stressors and their relationship to key mental health and functioning outcomes in a resettled refugee sample. METHOD: N = 656 refugees and asylum seekers living in Australia completed a survey in June 2020 to index their mental health (posttraumatic stress disorder (PTSD), depression, health anxiety and disability) and COVID-19 experiences. The relationship between COVID-19 stressors and mental health was examined using a series of hierarchical linear regression models while controlling for other key demographic factors. RESULTS: Refugees' most prevalent stressors related to worries of being infected by COVID-19 or the risk COVID-19 posed to others, which predicted health anxiety and PTSD. Social-related difficulties predicted depression and disability symptoms. Accessing and trusting information from authorities were the least prevalent stressors and were not significantly associated with mental health outcomes; neither was accessing basic supplies and financial support. Fears relating to the future such as concerns about visa application processes predicted health anxiety and disability. Crucially, the strongest predictor of all mental health outcomes was COVID-19 serving as a reminder of difficult past events. CONCLUSIONS: Refugees may be uniquely affected by COVID-19 because the pandemic serves as a reminder of their past conflict and persecution trauma. It is critical that mental health strategies accommodate the specific needs of refugees during the COVID-19 pandemic.

Antecedentes: Los refugiados pueden ser particularmente vulnerables a los efectos adversos de la pandemia del COVID-19 en la salud mental a consecuencia de sus pasados traumáticos y los desafíos del ambiente post migración.Objetivo: Evaluar la prevalencia de los estresores relacionados al COVID-19 y su relación a resultados claves funcionamiento y salud mental claves en una muestra de refugiados reubicados.Método: N = 656 refugiados y personas en búsqueda de asilo que viven en Australia completaron una encuesta en junio de 2020 para identificar su salud mental (trastorno de estrés postraumático (TEPT), depresión, ansiedad de salud y discapacidad) y las experiencias de COVID-19. Fueron examinadas la relación entre los estresores de COVID-19 y la salud mental usando una serie de modelos de regresión lineal jerárquica mientras se controlaron otros factores demográficos claves.Resultados: Los estresores más prevalentes de los refugiados se relacionaban con la preocupación de infectarse de COVID-19 o el riesgo del COVID-19 hacia otros, lo cual predijo la ansiedad de salud y TEPT. Las dificultades sociales predijeron los síntomas de depresión y discapacidad. Acceder y confiar en la información proporcionada por las autoridades fueron los estresores menos prevalentes y no se asociaron significativamente a los resultados de salud mental; tampoco lo fue el acceder a insumos básicos y apoyo financiero. Los temores asociados al futuro tales como preocupaciones sobre los procesos de aplicación a la visa predijeron la ansiedad de salud y discapacidad. De manera crucial, el predictor más fuerte de todos los resultados de salud mental fue el COVID-19 sirviendo como un recordatorio de los eventos pasados difíciles.Conclusiones: Los refugiados pueden estar afectados de forma única por el COVID-19 porque la pandemia sirve como un recordatorio de sus conflictos pasados y trauma de persecución. Es crítico que las estrategias de salud mental se acomoden a las necesidades específicas de los refugiados durante la pandemia del COVID-19.

Activating the attachment system modulates neural responses to threat in refugees with PTSD.

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.

Secure attachment primes reduce fear consolidation.

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.
