Article Synopsis
  • Refugees and asylum seekers often face post-migration living difficulties (PMLD) that are linked to psychological issues like post-traumatic stress (PTS).
  • Attachment insecurity, specifically anxiety and avoidance, might explain the connection between PMLD and PTS, but how it works isn't fully understood.
  • A study with 134 refugees in Switzerland found that PMLD can lead to PTS through attachment anxiety, and this relationship is further influenced by emotion dysregulation, suggesting a need for better assessment and treatment of these aspects in refugee care.

Background: Emotion regulation (ER) plays a central role in psychopathology. Understanding person-centred patterns of ER strategies is crucial for prevention and intervention strategies. However, there is a paucity of research on ER profiles and their psychological correlates in forcibly displaced people (FDP).

Background: Torture trauma is characterized 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 (TSs) and 44 non-TSs, all with a refugee background, completed a Go/NoGo response inhibition task during functional magnetic resonance imaging scanning. Data-driven independent component analysis identified active networks across the task and on Go, NoGo, and error of commission trials.

The refugee experience is typically characterized by exposure to numerous premigration traumatic events and postmigration stress in the resettlement environment. Refugees' experiences can lead to elevated rates of psychopathology, including posttraumatic stress disorder (PTSD) and depression. Emotion regulation is a key mechanism contributing to mental health outcomes among refugees.

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.

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.

Despite reporting elevated rates of posttraumatic stress disorder (PTSD), refugees are less likely than other groups to seek psychological treatment. Relatively little attention has been paid to the role of negative help-seeking beliefs in influencing treatment uptake. The current study sought to develop and psychometrically validate a novel measure indexing negative help-seeking beliefs for refugees (Help-Seeking Beliefs Scale [HSBS]).

As the premier global traumatic stress society, the International Society for Traumatic Stress Studies (ISTSS) has an important role to play in educating and raising awareness about the consequences of traumatic events, such as the war in Ukraine. On November 12, 2022, during its 38th annual meeting, the ISTSS hosted an invited Presidential Panel, chaired by Ananda Amstadter during her term as ISTSS President, that brought together trauma experts Peter Ventevogel, Marit Sijbrandij, Vitalii Klymchuck, Iryna Frankova, and Angela Nickerson to highlight how traumatic stress professionals can assist individuals affected by the war in Ukraine. The present paper summarizes the key points from the panel and discusses future challenges anticipated for people affected by the war.

Background And Objectives: Psychopathology has been associated with a deficit in emotion regulation (ER) flexibility - the ability to flexibly utilize ER strategies that are appropriate to situational demands. Yet, whether anxious individuals can be taught ER flexibility, or whether ER flexibility is effective in managing negative affect, remains unknown. We investigated the impact of instructed ER flexibility on emotional responding among individuals with differing levels of anxiety.

The number of refugees and internally displaced people in 2022 is the largest since World War II, and meta-analyses demonstrate that these people experience elevated rates of mental health problems. This review focuses on the role of posttraumatic stress disorder (PTSD) in refugee mental health and includes current knowledge of the prevalence of PTSD, risk factors, and apparent differences that exist between PTSD in refugee populations and PTSD in other populations. An emerging literature on understanding mechanisms of PTSD encompasses neural, cognitive, and social processes, which indicate that these factors may not function exactly as they have functioned previously in other PTSD populations.

Introduction: The vast majority of the 100 million forcibly displaced persons worldwide live in a state of prolonged uncertainty with limited resettlement prospects and access to resources. Little is known, however, regarding how refugees and asylum-seekers cope with this uncertainty.

Methods: In this study, we investigated the longitudinal association between a measure of how people cope with uncertainty (intolerance of uncertainty (IU)), fears for the future, posttraumatic stress disorder (PTSD) symptoms and depression symptoms.

The most used questionnaires for PTSD screening in adults were developed in English. Although many of these questionnaires were translated into other languages, the procedures used to translate them and to evaluate their reliability and validity have not been consistently documented. This comprehensive scoping review aimed to compile the currently available translated and evaluated questionnaires used for PTSD screening, and highlight important gaps in the literature.

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.

Background: This research examined the mental health of a cohort of asylum-seeking children, adolescents and their primary caregiver affected by insecure residency while living in the community, compared to refugees and immigrants.

Methods: The project investigated the prevalence of psychosocial problems among Iranian and Afghani asylum seeker, refugee and immigrant children and adolescents, and their caregivers who arrived in Australia from 2010. In total, =196 children and adolescents aged 5-18 years, and their primary caregiver were asked about family visa status, country of origin, level of education, parent symptoms of posttraumatic stress disorder (Harvard Trauma Questionnaire) and child wellbeing (Strengths and Difficulties Questionnaire).

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 community settings prior to resettlement impacted the course of refugees' psychological distress over the 4 years following arrival in Australia.

Objective: A prior study with people exposed to a traumatic event indicated that posttraumatic anger is a multidimensional construct that consists of five factors comprising anger at (a) the criminal justice system, (b) other people, (c) the self, and (d) a perpetrator and (e) a desire for revenge. Preliminary evidence shows that anger at the self and perpetrators is related to posttraumatic stress disorder (PTSD) symptoms. Expanding the focus from trauma victims to people exposed to a traumatic loss of a significant other, for example, due to road traffic accidents, may enhance our knowledge on factors that are amenable to change in the treatment of prolonged grief disorder (PGD) and PTSD.
