RESUMEN
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.

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.

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.

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.

OBJECTIVE: Many refugees experience prolonged separation from family members, which research suggests has adverse effects on mental health and post-displacement outcomes in refugee populations. We examine mental health differences in refugees separated and not separated from their families, and key post-migration factors and cultural mechanisms that may underlie this impact. METHODS: A sample of 1085 refugees resettled in Australia, of which 23.3% were separated from all of their immediate family, took part in an online battery of survey measures indexing pre- and post-migration refugee experiences, mental health symptoms, disability and individualistic/collectivistic self-identity. Family separation was used as a predictor of mental health outcomes in a series of linear regressions, and the separated and non-separated groups were compared in multigroup path analysis models to examine group-specific indirect effects. RESULTS: The separated group reported greater exposure to pre-migration potentially traumatic events and higher levels of post-migration living difficulties compared to the non-separated group. Family separation predicted higher post-traumatic stress and depression symptoms, but not disability, after controlling for potentially traumatic event exposure, age and sex. Path analyses revealed distinct indirect effects for separated and non-separated groups. Principally, higher collectivistic self-identity was associated with elevated post-traumatic stress, depression and disability symptoms via social-related post-migration living difficulties such as isolation and loneliness in the separated group; whereas collectivism was linked with increased depression symptoms via economic-related post-migration living difficulties in the non-separated group. CONCLUSION: These findings indicate that family separation powerfully influences mental health outcomes, but that its effect may be mediated by the type of post-migration stress experienced in the settlement environment and culturally bound differences in how the sense of self is interconnected with family.

In this paper, we draw on empirical research and theoretical models of refugee and posttrauma mental health to propose the "Psychological Interaction with Environment (PIE) Matrix Model" of refugee mental health. This model focuses on the mental health of adult refugees and proposes that psychological factors and the external environment interact to influence mental health outcomes and functioning for individuals with refugee backgrounds. Environmental factors include adversity faced before, during, and after the migration journey, including adversity faced in a resettlement or postdisplacement environment. Psychological factors refer to psychological (i.e., cognitive and emotional) mechanisms that individuals may use to cope with adversity. We posit that individuals from refugee backgrounds are likely to show individual differences in psychological processes that may protect against or underpin the development and maintenance of psychopathology following exposure to trauma and displacement. The PIE Matrix Model proposes a framework to guide intervention by identifying key pathways by which psychological and environmental factors impact one another. We suggest that psychological interventions can be targeted according to the kind and level of support different individuals may require, based on individualized and context-driven assessments of the interaction between environmental and psychological factors at any given point in time. This model draws on existing models of refugee adaptation and highlights the need for longitudinal and experimental research to explain the interaction between these factors and their causal impact on refugee mental health.

BACKGROUND: Refugees report elevated rates of posttraumatic stress disorder (PTSD), but are relatively unlikely to seek help for their symptoms. Mental health stigma is a key barrier to help-seeking amongst refugees. We evaluated the efficacy of an online intervention in reducing self-stigma and increasing help-seeking in refugee men. METHODS: Participants were 103 refugee men with PTSD symptoms from Arabic, Farsi or Tamil-speaking backgrounds who were randomly assigned to either receive an 11-module online stigma reduction intervention specifically designed for refugees ('Tell Your Story', TYS) or to a wait-list control (WLC) group. Participants completed online assessments of self-stigma for PTSD and help-seeking, and help-seeking intentions and behaviors at baseline, post-intervention, and at a 1 month follow-up. RESULTS: Intent-to-treat analyses indicated that, compared to the WLC, TYS resulted in significantly smaller increases in self-stigma for seeking help from post-treatment to follow-up (d = 0.42, p = 0.008). Further, participants in the TYS conditions showed greater help-seeking behavior from new sources at follow-up (B = 0.69, 95% CI 0.19-1.18, p = 0.007) than those in the WLC. The WLC showed significantly greater increases in help-seeking intentions from post-intervention to follow-up (d = 0.27, p = 0.027), relative to the TYS group. CONCLUSIONS: This is the first investigation of a mental health stigma reduction program specifically designed for refugees. Findings suggest that evidence-based stigma reduction strategies are beneficial in targeting self-stigma related to help-seeking and increasing help-seeking amongst refugees. These results indicate that online interventions focusing on social contact may be a promising avenue for removing barriers to accessing help for mental health symptoms in traumatized refugees.

BACKGROUND: The mental health and social functioning of millions of forcibly displaced individuals worldwide represents a key public health priority for host governments. This is the first longitudinal study with a representative sample to examine the impact of interpersonal trust and psychological symptoms on community engagement in refugees. METHODS: Participants were 1894 resettled refugees, assessed within 6 months of receiving a permanent visa in Australia, and again 2-3 years later. Variables measured included post-traumatic stress disorder symptoms, depression/anxiety symptoms, interpersonal trust and engagement with refugees' own and other communities. RESULTS: A multilevel path analysis was conducted, with the final model evidencing good fit (Comparative Fit Index = 0.97, Tucker-Lewis Index = 0.89, Root Mean Square Error of Approximation = 0.05, Standardized Root-Mean-Square-Residual = 0.05). Findings revealed that high levels of depression symptoms were associated with lower subsequent engagement with refugees' own communities. In contrast, low levels of interpersonal trust were associated with lower engagement with the host community over the same timeframe. CONCLUSIONS: Findings point to differential pathways to social engagement in the medium-term post-resettlement. Results indicate that depression symptoms are linked to reduced engagement with one's own community, while interpersonal trust is implicated in engagement with the broader community in the host country. These findings have potentially important implications for policy and clinical practice, suggesting that clinical and support services should target psychological symptoms and interpersonal processes when fostering positive adaptation in resettled refugees.

Refugees who suffer from posttraumatic stress disorder (PTSD) often react with strong emotions when confronted with trauma reminders. In this study, we aimed to investigate the associations between low emotion regulation capacity (as indexed by low heart rate variability [HRV]), probable PTSD diagnosis, and fear and anger reaction and recovery to trauma-related stimuli. Participants were 81 trauma-exposed refugees (probable PTSD, n = 23; trauma-exposed controls, n = 58). The experiment comprised three 5-min phases: a resting phase (baseline); an exposition phase, during which participants were exposed to trauma-related images (stimulus); and another resting phase (recovery). We assessed HRV at baseline, and fear and anger were rated at the end of each phase. Linear mixed model analyses were used to investigate the associations between baseline HRV and probable DSM-5 PTSD diagnosis in influencing anger and fear responses both immediately after viewing trauma-related stimuli and at the end of the recovery phase. Compared to controls, participants with probable PTSD showed a greater increase in fear from baseline to stimulus presentation, d = 0.606. Compared to participants with low emotion regulation capacity, participants with high emotion regulation capacity showed a smaller reduction in anger from stimulus presentation to recovery, d = 0.548. Our findings indicated that following exposure to trauma-related stimuli, probable PTSD diagnosis predicted increased fear reactivity, and low emotion regulation capacity predicted decreased anger recovery. Impaired anger recovery following trauma reminders in the context of low emotion regulation capacity might contribute to the increased levels of anger found in postconflict samples.
Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Reactividad Emocional, Capacidad de Regulación Emocional y trastorno por Estrés Postraumático en Refugiados Traumatizados: Una Investigación Experimental REACTIVIDAD EMOCIONAL, REGULACION EMOCIONAL Y TEPT Los refugiados que sufren de trastorno de estrés postraumático (TEPT) a menudo reaccionan con emociones fuertes cuando se enfrentan a recordatorios de trauma. El objetivo de este estudio fue investigar las asociaciones entre la baja capacidad de regulación emocional (según la variabilidad de la frecuencia cardíaca [HRV en su sigla en inglés]), el diagnóstico probable de TEPT y la reacción de miedo e ira, y la recuperación ante estímulos relacionados-al-trauma. Los participantes fueron 81 refugiados expuestos a traumas (TEPT probable, n = 23; controles expuestos a traumas, n = 58). El experimento estuvo compuesto por tres fases de 5 minutos: una fase de reposo (línea base); una fase de exposición, durante la cual los participantes fueron expuestos a imágenes relacionadas-al-trauma (estímulo); y otra fase de reposo (recuperación). Se evaluó la HRV al inicio, y el miedo y la ira se evaluaron al final de cada fase. Se utilizaron análisis de modelos lineales mixtos para investigar las asociaciones entre la HRV basal y el diagnóstico probable de TEPT DSM-5 para influir en las respuestas de ira y miedo, inmediatamente después de ver los estímulos relacionados-al-trauma y al final de la fase de recuperación. En comparación con los controles, los participantes con TEPT probable mostraron un mayor incremento en miedo desde la línea base hasta la presentación del estímulo, d = 0.606. En comparación a los participantes con baja capacidad de regulación emocional, los participantes con alta capacidad de regulación emocional mostraron una menor reducción en ira desde la presentación del estímulo a la recuperación, d = 0.548. Nuestros hallazgos indican que el diagnóstico de TEPT probable predice un aumento de la reactividad al miedo y una baja capacidad de regulación emocional predice una disminución de la recuperación de ira tras la exposición a estímulos relacionados-al-trauma. Nuestros hallazgos indican que el diagnóstico de TEPT probable predice un aumento de la reactividad al miedo y una baja capacidad de regulación emocional predice una disminución de la recuperación de ira después de la exposición a estímulos relacionados-al-trauma. La recuperación de ira deteriorada seguida a los recuerdos traumáticos en el contexto de una baja capacidad de regulación emocional podría contribuir al aumento de los niveles de ira que se encuentran en las muestras posteriores al conflicto.

Although it is well documented that exposure to severe, cumulative trauma and postdisplacement stress increases the risk for posttraumatic stress symptom disorder (PTSD), less is known about the representation and predictors of complex PTSD (CPTSD) symptoms in refugee populations. We examined PTSD and CPTSD symptom profiles (co-occurring PTSD and disturbances in self-organization [DSO] symptoms) and their premigration, postmigration, and demographic predictors, using latent class analysis (LCA), in a cohort of 112 refugees resettled in Australia. The LCA identified a four-factor model as the best fit to the data, comprising classes categorized as: (a) CPTSD, exhibiting high levels of PTSD and DSO symptoms (29.5%); (b) PTSD only (23.5%); (c) high affective dysregulation (AD) symptoms (31.9%); and (d) low PTSD and DSO symptoms (15.1%). Membership in the CPTSD and PTSD classes was specifically associated with cumulative traumatization, CPTSD OR = 1.56, 95% CI [1.15, 2.12], and PTSD OR = 1.64, 95% CI [1.15, 2.34]; and female gender, CPTSD OR = 14.18, 95% CI [1.66, 121.29], and PTSD OR = 16.84, 95% CI [1.78, 159.2], relative to the low-symptom class. Moreover, CPTSD and AD class membership was significantly predicted by insecure visa status, CPTSD OR = 7.53, 95% CI [1.26, 45.08], and AD OR = 7.19, 95% CI [1.23, 42.05]. These findings are consistent with the ICD-11 model of CPTSD and highlight the contributions of cumulative trauma to CPTSD and PTSD profiles as well as of contextual stress from visa uncertainty to DSO symptom profiles in refugee cohorts, particularly those characterized by AD.
Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Perfiles de Síntomas de Trastorno de Estrés Postraumático Complejo en Refugiados Traumatizados PERFILES DE SÍNTOMAS DE TEPT COMPLEJO EN REFUGIADOS TRAUTATIZADOS Aunque está bien documentado que la exposición a trauma severo y acumulativo y el estrés posterior al desplazamiento en poblaciones de refugiados aumenta el riesgo de trastorno por síntomas de estrés postraumático (TEPT), se conoce menos acerca de la representación y los predictores de síntomas del TEPT complejo (TEPT-C). Examinamos los perfiles de síntomas de TEPT y TEPT-C (TEPT concurrente y síntomas de alteraciones en la auto-organización [DSO en su sigla en inglés]) y su pre-migración, post-migración y predictores demográficos, utilizando el análisis de clases latentes (ACL), en una cohorte de 112 refugiados reasentados en Australia. El ACL identificó un modelo de cuatro factores como el que mejor se ajusta a los datos, que comprende clases clasificadas tales como: (a) TEPT-C, que exhiben altos niveles de síntomas de TEPT y DSO (29.5%); (b)TEPT (23.5%); (c) síntomas de alta desregulación afectiva (DA) (31,9%); y (d) síntomas bajos de TEPT y DSO (15,1%). La adscripción en las clases de TEPT-C y TEPT se asociaron específicamente con traumatización acumulativa, TEPT-C OR = 1.56, IC 95% [1.15, 2.12] y TEPT OR = 1.64, IC 95% [1.15, 2.34]; y género femenino, TEPT-C OR = 14.18, IC 95% [1.66, 121.29], y TEPT OR = 16.84, IC 95% [1.78, 159.2], en relación con la clase de síntomas bajos. Además, la adscripción a la clase TEPT-C y AD se predijo significativamente por la inseguridad en el estado de su visa, TEPT-C OR = 7.53, IC 95% [1.26, 45.08], y AD OR = 7.19, IC 95% [1.23, 42.05]. Estos hallazgos son consistentes con el modelo CIE-11 de TEPT-C y destacan las contribuciones del trauma acumulativo a los perfiles de TEPT-C y TEPT, así como del estrés contextual desde la incertidumbre del estado de las visas hasta los perfiles de síntomas de DSO en cohortes de refugiados, particularmente en aquellos caracterizados por DA.

Refugees demonstrate high rates of post-traumatic stress disorder (PTSD) and other psychological disorders. The recent increase in forcible displacement internationally necessitates the understanding of factors associated with refugee mental health. While pre-migration trauma is recognized as a key predictor of mental health outcomes in refugees and asylum seekers, research has increasingly focused on the psychological effects of post-migration stressors in the settlement environment. This article reviews the research evidence linking post-migration factors and mental health outcomes in refugees and asylum seekers. Findings indicate that socioeconomic, social, and interpersonal factors, as well as factors relating to the asylum process and immigration policy affect the psychological functioning of refugees. Limitations of the existing literature and future directions for research are discussed, along with implications for treatment and policy.

BACKGROUND: Cumulative exposure to potentially traumatic events (PTEs) increases risk for mental distress in conflict-affected settings, but the psychophysiological mechanisms that mediate this dose-response relationship are unknown. We investigated diminished heart rate variability (HRV) - an index of vagus nerve function and a robust predictor of emotion regulation capacity - as a vulnerability marker that potentially mediates the association between PTE exposure, age and symptoms of posttraumatic stress disorder (PTSD), psychological distress and aggressive behavior, in a community sample from Timor-Leste - a post-conflict country with a history of mass violence. METHOD: Resting state heart rate data was recorded from 45 cases of PTSD, depression and intermittent explosive disorder (IED); and 29 non-case controls. RESULTS: Resting HRV was significantly reduced in the combined case group compared with non-cases (p = .021; Cohen's d = 0.5). A significant mediation effect was also observed, whereby a sequence of increased age, reduced HRV and elevated PTSD symptoms mediated the association between PTE exposure and distress (B = .06, SE = .05, 95% CI = [.00-.217]) and aggression (B = .02, SE = .02, 95% CI = [.0003-.069])). CONCLUSION: The findings demonstrate an association between diminished resting HRV and psychopathology. Moreover, age-related HRV reductions emerged as a potential psychophysiological mechanism that underlies enhanced vulnerability to distress and aggression following cumulative PTE exposure.

BACKGROUND: While a large proportion of conflict-affected populations have been dually exposed to trauma and loss, there is inadequate research identifying differential symptom profiles related to bereavement and trauma exposure in these groups. The objective of this study were to (1) determine whether there are distinct classes of posttraumatic stress disorder (PTSD) and prolonged grief disorder (PGD) symptoms in bereaved trauma survivors exposed to conflict and persecution, and (2) examine whether particular types of refugee experiences and stressors differentially predict symptom profiles. METHODS: Participants were 248 Mandaean adult refugees who were assessed at an average of 4.3 years since entering Australia following persecution in Iraq. PTSD, PGD, trauma exposure, adjustment difficulties since relocation, and English proficiency were measured. Latent class analysis was used to elucidate symptom profiles of PTSD and PGD in this sample. RESULTS: Latent class analysis revealed four classes of participants: a combined PTSD/PGD class (16%), a predominantly PTSD class (25%), a predominantly PGD class (16%), and a resilient class (43%). Whereas membership in the PTSD/PGD class was predicted by exposure to traumatic loss, those in the PGD class were more likely to have experienced adaptation difficulties since relocation, and individuals in the PTSD class were more likely to have experienced difficulties related to loss of culture and support. CONCLUSIONS: This study provides evidence that specific symptom patterns emerge following exposure to mass trauma and loss. These profiles are associated with distinct types of traumatic experiences and post-migration living difficulties. These results have substantial public health implications for assessment and intervention following mass trauma.

BACKGROUND: Torture trauma is characterised by intentional uncontrollable acts, but the long-term effects of torture exposure on cognitive control brain mechanisms are unknown. METHODS: A final sample of 33 torture survivors (TS) and 44 non-torture survivors (NTS), all with a refugee background, completed a Go/NoGo response inhibition task during fMRI scanning. Data-driven independent components analysis identified active networks across the task, and within Go, NoGo and error of commission trials. Groups were compared on within/between network connectivity, controlling for demographic and psychological symptom covariates. Secondary analyses investigated whether network connectivity moderated the associations between torture exposure and severity on fear (e.g. re-experiencing) and dysphoria (e.g. anhedonia) posttraumatic stress disorder (PTSD) symptoms. RESULTS: The TS group exhibited decreased connectivity (compared to NTS controls) within the posterior default mode network (specifically the left precuneus) and auditory-motor network (specifically right superior temporal gyrus STG), and reduced connectivity between the dorsomedial frontal network (dmFN) and dorsal attention network (dAN) across the Go/NoGo task. The TS group also showed comparatively more negative ventral attention network connectivity during NoGo (i.e. inhibition) trials. No behavioral effects were observed. Secondary analyses revealed that association between torture exposure and elevated PTSD dysphoria (not fear) symptoms was moderated by reduced connectivity in the right STG and between the dmFN-dAN. CONCLUSIONS: Response inhibition, attention and motor networks appear less connected in torture survivors, which may be specifically linked to PTSD dysphoria symptom profiles. Findings suggest that targeting cognitive control processes may hold promise for alleviating post-traumatic symptoms amongst survivors of torture.
RESUMEN
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.

RESUMEN
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.

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.

BACKGROUND: Studies suggest that immigrants have higher rates of anxiety-depression than compatriots in low-middle income countries and lower rates than populations in host high income countries. Elucidating the factors that underlie these stepwise variations in prevalence may throw new light on the pathogenesis of anxiety-depressive disorders globally. This study aimed to examine whether quantitative differences in exposure to, or the interaction between, risk factors account for these anxiety-depression prevalence differences amongst immigrant relative to source and host country populations. METHODS: Multistage population mental health surveys were conducted in three groups: 1) a Vietnamese-immigrant sample settled in Australia (n = 1161); 2) a Vietnamese source country sample residing in the Mekong Delta region (n = 3039); 3) an Australian-born host country sample (n = 7964). Multivariable logistic regression analyses compared risk factors between the Vietnamese-immigrant group and: 1) the Mekong Delta Vietnamese; and 2) the Australian-born group. Twelve month anxiety-depression diagnoses were the main outcome measures, derived from the Composite International Diagnostic Interview (CIDI), supplemented by an indigenously derived measure - the Phan Vietnamese Psychiatric Scale (PVPS) in both Vietnamese groups. RESULTS: The 12-month prevalence of anxiety-depression showed a stepwise increase across groups: Mekong Delta Vietnamese 4.8%; Vietnamese-immigrants 7.0%; Australian-born 10.2%. The two Vietnamese populations showed a similar risk profile with older age, exposure to potentially traumatic events (PTEs), multiple physical illnesses and substance use disorder (SUD) being associated with anxiety-depression, with the older Vietnamese-immigrants reporting greater exposure to these factors. The interaction between key risk factors differed fundamentally when comparing Vietnamese-immigrant and Australian-born samples. Age emerged as the major discriminator, with young Vietnamese-immigrants exhibiting particularly low rates of anxiety-depression. CONCLUSIONS: The findings reported here suggest that core risk factors for anxiety-depression may be universal, but their patterning and interaction may differ according to country-of-origin. The study also highlights the importance of including both standard international and culturally-specific measures to index cross-cultural manifestations of common mental disorders.

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).

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).
