Avoidance in posttraumatic stress among refugee survivors of violent conflict and atrocities: Testing trans-cultural risk processes and candidate intervention targets

COVID-19 and Mental Health Among People Who Are Forcibly Displaced: The Role of Socioeconomic Insecurity

OBJECTIVE

Forcibly displaced persons may be at elevated risk for poor mental health outcomes because of the COVID-19 pandemic. This study sought to examine associations between COVID-19-related socioeconomic insecurity and mental health outcomes among asylum seekers.

METHODS

The authors evaluated the association between the degree of food, housing, and income insecurity related to the pandemic and mental health outcomes among East African asylum seekers in a high-risk, postdisplacement setting in the Middle East (i.e., Israel).

RESULTS

Anxiety symptom severity (p=0.03) as well as the rate of suicidal ideation among women (odds ratio [OR]=2.81, p=0.016) were significantly elevated in a community sample of asylum seekers during the COVID-19 pandemic (N=66) relative to a similar sample (N=158) from the same community and context assessed before the pandemic. No differences between the two groups were observed for severity or rate of probable depression or posttraumatic stress disorders. In addition, among the sample assessed during the pandemic, socioeconomic insecurity due to the pandemic was strongly associated with elevated symptom severity and probable anxiety, depression, and posttraumatic stress disorders as well as suicidal ideation (R² range=0.19-0.35; OR range=4.54-5.46).

CONCLUSIONS

Findings are consistent with growing evidence of a mental health crisis among asylum seekers that is linked to COVID-19 control policies and residential status policies. The results highlight the risk for suicidal ideation linked to intersectional marginalization among female asylum seekers. These findings may inform postdisplacement policy making, social justice advocacy, humanitarian aid, and clinical science and practice to mitigate poor mental health outcomes associated with COVID-19 among forcibly displaced persons.

Prevalence and prevention of suicidal ideation among asylum seekers in a high-risk urban post-displacement setting

AIMS

Among asylum seekers in a high-risk unstable post-displacement context, we aimed to investigate the prevalence of and risk for suicidal ideation (study 1), and then to test whether and how Mindfulness-Based Trauma Recovery for Refugees (MBTR-R) may prevent or treat suicidal ideation (study 2).

METHODS

Study 1 was conducted among a community sample of N = 355 (31.8% female) East African asylum seekers in a high-risk urban post-displacement setting in the Middle East (Israel). Study 2 was a secondary analysis of a randomised waitlist-control trial of MBTR-R among 158 asylum-seekers (46.2% female) from the same community and post-displacement setting.

RESULTS

Prevalence of suicidal ideation was elevated (31%). Post-migration living difficulties, as well as posttraumatic stress, depression, anxiety and their multi-morbidity were strongly associated with suicidal ideation severity. Likewise, depression and multi-morbidity prospectively predicted the onset of suicidal ideation. Relative to its incidence among waitlist-control (23.1%), MBTR-R prevented the onset of suicidal ideation at post-intervention assessment (15.6%) and 5-week follow-up (9.8%). Preventive effects of MBTR-R on suicidal ideation were mediated by reduced posttraumatic stress, depression, anxiety and their multi-morbidity. MBTR-R did not therapeutically reduce current suicidal ideation present at the beginning of the intervention.

CONCLUSIONS

Findings warn of a public health crisis of suicidality among forcibly displaced people in high-risk post-displacement settings. Although preliminary, novel randomised waitlist-control evidence for preventive effects of MBTR-R for suicidal ideation is promising. Together, findings indicate the need for scientific, applied and policy attention to mental health post-displacement in order to prevent suicide among forcibly displaced people.

Neural correlates of emotional reactivity and regulation in traumatized North Korean refugees

Refugees often report heightened emotional reactivity and emotion regulation difficulties and are at high risk for mental health problems. Given that refugees are repeatedly exposed to traumatic events that may cause changes in the brain, the present study examined neural correlates of emotional reactivity and regulation and their associations with refugee features (e.g., cumulative trauma) and the severity of psychiatric symptoms (e.g., post-traumatic stress disorder [PTSD]) in North Korean (NK) refugees. Forty NK refugees with trauma exposure and varying levels of psychopathology and 41 healthy South Korean (SK) controls without trauma exposure participated in this study. They performed an emotion regulation task during a functional magnetic resonance imaging (fMRI) assessment. Region of interest (ROI), whole brain, and generalized psychophysiological interaction (gPPI) analyses were conducted. NK refugees with trauma exposure and varying levels of psychopathology showed increased activation in response to negative socio-affective pictures in regions involved in affective processing, including the amygdala and hippocampus, relative to healthy SK controls without trauma exposure. They also exhibited greater prefrontal cortex (PFC) activation, amygdala-PFC functional connectivity (FC), and hippocampal-PFC FC during emotion regulation. More severe PTSD symptoms were associated with greater hippocampal response to negative pictures (vs. neutral pictures) in NK refugees. This study provides neuroscientific evidence for neural alterations in association with emotional reactivity and regulation in traumatized refugees. These findings may contribute to a better mechanistic understanding of emotional reactivity and regulation in refugees and suggest potential ways to address the emotional and mental problems of traumatized refugees.

A Functional Network Perspective on Posttraumatic Stress in Refugees: Implications for Theory, Classification, Assessment, and Intervention

There is an important, long-standing debate regarding the universality vs. specificity of trauma-related mental health symptoms in socio-culturally and linguistically diverse population groups, such as refugees and asylum seekers. Network theory, an emerging development in the field of psychological science, provides a novel data analytic methodology to evaluate and empirically examine long-standing questions about the structure and function of posttraumatic stress symptoms. We sought to empirically model the functional network of posttraumatic stress symptoms among East African refugees who survived multiple potentially traumatic events. A sample of 148 Sudanese and Eritrean male asylum seekers (M(SD)_age = 32.60(7.13) were recruited from the community in Israel. The nature and function(s) of posttraumatic symptoms (Harvard Trauma Questionnaire) were modeled using regularized partial correlation models to derive a network of symptoms. Spinglass and exploratory graph analysis walktrap algorithms were then used to identify functional "circuits of symptoms" or clusters of nodes within the network. Analyses revealed a functional symptom circuitry that shares features with the predominant western model of posttraumatic stress disorder; as well as unique functional clusters of symptoms inconsistent with nosology and symptomatology observed in studies of Western populations. Findings may have important implications for theory, classification, assessment, candidate mechanisms that may drive and maintain posttraumatic stress, and in turn may inform prevention or treatment for socio-culturally diverse forcibly displaced population groups.
