Social functioning is a crucial aspect of psychosocial adaptation following forced displacement. Yet, it has received far less attention than understanding and addressing mental health problems among refugees and asylum-seekers. This study aimed to extend the ecological model of refugee distress – one of the most widely used frameworks in refugee mental health – to social functioning, and to identify direct and indirect pathways from established conflict- and displacement-related factors to social functioning alongside mental health problems.

An online study with 1,235 refugees in Indonesia was conducted over a 2-year period. Conflict-related traumatic experiences before arrival in Indonesia, post-displacement stressors in the past 12 months, were measured at the onset of the study, while social functioning and mental health outcomes (symptoms of posttraumatic stress disorder, depression, and anger) were assessed 1 year later.

Longitudinal Structural Equation Modelling analysis revealed that diversity of conflict-related trauma predicted more post-displacement stress (β = 0.45, SE = 0.03, p < 0.001), higher mental health problems (β = 0.13, SE = 0.05, p = 0.004), but increased social functioning 1 year later (β = 0.10, SE = 0.04, p = 0.011), while post-displacement stressors predicted poorer mental health (β = 0.46, SE = 0.05, p < 0.011) and reduced social functioning (β = −0.09, SE = 0.04, p = 0.041). The indirect pathway from traumatic experiences via post-displacement stressors was positive for mental health (β = 0.21, 95% CI = 0.162–0.257) and negative for social functioning (β = −0.04, 95% CI = −0.082 to −0.003).

This study conceptually and empirically extended the ecological model of refugee distress to social functioning by highlighting the dual influences of conflict-related traumatic experiences. The findings provide a springboard for advancing research and practice in the mental health and psychosocial field.

Trauma-related psychopathology is markedly elevated among refugee populations, particularly those living in sustained displacement. While economic, social and psychological factors have been linked to the deterioration of mental health following trauma and displacement, these factors have rarely been investigated concurrently and longitudinally. Consequently, there is little information on the potential longitudinal mechanisms driving mental ill-health in displacement settings. This study explored the temporal association between economic stressors, social stressors, emotion dysregulation and psychopathology in 1,235 refugees displaced in Indonesia.

Refugee participants from Farsi, Dari, Arabic, Somali and English-speaking backgrounds completed an online survey at four timepoints, 6 months apart. Factors of interest were measured using validated instruments including the Patient Health Questionnaire (to assess depressive symptoms), Posttraumatic Diagnostic Scale (to assess posttraumatic stress [PTS] symptoms), Post-Migration Living Difficulties Checklist (to index economic and social stressors) and Difficulties in Emotion Regulation Scale (to assess emotion dysregulation).

Random-intercept cross-lagged panel analysis revealed that economic stressors and emotion dysregulation were central to the longitudinal course of trauma-related psychopathology. Specifically, economic stressors were associated with subsequent increases in PTS symptoms (B = 0.07, p = 0.047), depressive symptoms (B = 0.17, p < .001) and social stressors (B = 0.28, p < .001), while emotion dysregulation was antecedent to increases in PTS (B = 0.16, p < .001), depression symptoms (B = 0.13, p < .001), and social stressors (B = 0.10, p = .017). Additionally, depression was associated with subsequent increases in economic stressors (B = 0.18, p = .001) and social stressors were associated with subsequent increases in economic stressors (B = 0.12, p = .037).

The current study identified both economic stressors and emotion dysregulation as the main drivers of psychopathology for refugees. This indicates that both the structural barriers encountered in the environment and one’s internal capacity have a substantial impact on wellbeing. These findings highlight that alongside psychological interventions, policy changes that facilitate economic empowerment are critically, and equally, important.

Refugee experiences of trauma and displacement can significantly disrupt established social networks. While social functioning has been routinely associated with mental health, to our knowledge, no study has tested the direction of influence between social and psychological functioning within displaced refugee communities. This study investigated the temporal association between psychological symptoms (PTSD, depression, anger) and multiple facets of social functioning (including community connectedness, perceived social responsibility, positive social support and negative social support).

A culturally diverse sample of refugees (N = 1,235) displaced in Indonesia completed an online survey at four time-points, six months apart. Longitudinal structural equation modelling was used to investigate the temporal ordering between psychological symptoms and social functioning.

Findings revealed that greater psychological symptoms were associated with a subsequent deterioration in social functioning (decreased positive social support and community connectedness and increased negative social support and perceived social responsibility). Greater perceived social responsibility was also associated with subsequent increases in psychological symptoms, while positive social support and community connectedness were bi-directionally associated over-time.

These findings highlight the potential utility of mental health interventions for displaced refugees as a means to improve social functioning and inclusion with host communities. Findings have important implications in guiding the development of interventions and allocation of resources to support refugee engagement and wellbeing in displacement contexts.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Although emergency service personnel experience markedly elevated the rates of post-traumatic stress disorder (PTSD), there are no rigorously conducted trials for PTSD in this population. This study assessed the efficacy of cognitive behaviour therapy (CBT) for PTSD in emergency service personnel, and examined if brief exposure (CBT-B) to trauma memories is no less efficacious as prolonged exposure (CBT-L).

One hundred emergency service personnel with PTSD were randomised to either immediate CBT-L, CBT-B or wait-list (WL). Following post-treatment assessment, WL participants were randomised to an active treatment. Participants randomised to CBT-L or CBT-B were assessed at baseline, post-treatment and at 6-month follow-up. Both CBT conditions involved 12 weekly individual sessions comprising education, CBT skills building, imaginal exposure, in vivo exposure, cognitive restructuring and relapse prevention. Imaginal exposure occurred for 40 min per session in CBT-L and for 10 min in CBT-B.

At post-treatment, participants in WL had smaller reductions in PTSD severity (Clinician Administered PTSD Scale), depression, maladaptive appraisals about oneself and the world, and smaller improvements on psychological and social quality of life than CBT-L and CBT-B. There were no differences between CBT-L and CBT-B at follow-up on primary or secondary outcome measures but both CBT-L and CBT-B had large baseline to follow-up effect sizes for reduction of PTSD symptoms.

This study highlights that CBT, which can include either long or brief imaginal exposure, is efficacious in reducing PTSD in emergency service personnel.

The majority of survivors of mass violence live in low- and middle-income countries (LMICs).

To synthesise empirical findings for psychological interventions for children and adolescents with post-traumatic stress disorder (PTSD) and/or depression in LMICs affected by mass violence.

Randomised controlled trials with children and adolescents with symptoms of PTSD and/or depression in LMICs were identified. Overall, 21812 records were found through July 2016 in the Medline, PsycINFO and PILOTS databases; 21 met the inclusion criteria and were reviewed according to recommended guidelines.

Twenty-one studies were included. Active treatments for PTSD yielded large pre-treatment to post-treatment changes (g = 1.15) and a medium controlled effect size (g = 0.57). Effect sizes were similar at follow-up. Active treatments for depression produced small to medium effect sizes. Finally, after adjustment for publication bias, the imputed uncontrolled and controlled effect sizes for PTSD were medium and small respectively.

Psychological interventions may be effective in treating paediatric PTSD in LMICs. It appears that more targeted approaches are needed for depressive responses.

Traumatic injuries affect millions of patients each year, and resulting post-traumatic stress disorder (PTSD) significantly contributes to subsequent impairment.

To map the distinctive long-term trajectories of PTSD responses over 6 years by using latent growth mixture modelling.

Randomly selected injury patients (n = 1084) admitted to four hospitals around Australia were assessed in hospital, and at 3, 12, 24 and 72 months. Lifetime psychiatric history and current PTSD severity and functioning were assessed.

Five trajectories of PTSD response were noted across the 6 years: (a) chronic (4%), (b) recovery (6%), (c) worsening/recovery (8%), (d) worsening (10%) and (e) resilient (73%). A poorer trajectory was predicted by female gender, recent life stressors, presence of mild traumatic brain injury and admission to intensive care unit.

These findings demonstrate the long-term PTSD effects that can occur following traumatic injury. The different trajectories highlight that monitoring a subset of patients over time is probably a more accurate means of identifying PTSD rather than relying on factors that can be assessed during hospital admission.

The latent structure of the proposed ICD-11 post-traumatic stress disorder (PTSD) symptoms has not been explored.

To investigate the latent structure of the proposed ICD-11 PTSD symptoms.

Confirmatory factor analyses using data from structured clinical interviews administered to injury patients (n = 613) 6 years post-trauma. Measures of disability and psychological quality of life (QoL) were also administered.

Although the three-factor model implied by the ICD-11 diagnostic criteria fit the data well, a two-factor model provided equivalent, if not superior, fit. Whereas diagnostic criteria based on this two-factor model resulted in an increase in PTSD point prevalence (5.1%v. 3.4%; z = 2.32,P<0.05), they identified individuals with similar levels of disability (P = 0.933) and QoL(P = 0.591) to those identified by the ICD-11 criteria.

Consistent with theorised reciprocal relationships between re-experiencing and avoidance in PTSD, these findings support an alternative diagnostic algorithm requiring at least two of any of the four re-experiencing/avoidance symptoms and at least one of the two hyperarousal symptoms.

There have been changes to the criteria for diagnosing post-traumatic stress disorder (PTSD) in DSM-5 and changes are proposed for ICD-11.

To investigate the impact of the changes to diagnostic criteria for PTSD in DSM-5 and the proposed changes in ICD-11 using a large multisite trauma-exposed sample and structured clinical interviews.

Randomly selected injury patients admitted to four hospitals were assessed 72 months post trauma (n = 510). Structured clinical interviews for PTSD and major depressive episode, as well as self-report measures of disability and quality of life were administered.

Current prevalence of PTSD under DSM-5 scoring was not significantly different from DSM-IV (6.7% v. 5.9%, z = 0.53, P = 0.59). However, the ICD-11 prevalence was significantly lower than ICD-10 (3.3% v. 9.0%,z =–3.8, P<0.001). The PTSD current prevalence was significantly higher for DSM-5 than ICD-11 (6.7%v. 3.3%, z = 2.5, P = 0.01). Using ICD-11 tended to show lower rates of comorbidity with depression and a slightly lower association with disability.

The diagnostic systems performed in different ways in terms of current prevalence rates and levels of comorbidity with depression, but on other broad key indicators they were relatively similar. There was overlap between those with PTSD diagnosed by ICD-11 and DSM-5 but a substantial portion met one but not the other set of criteria. This represents a challenge for research because the phenotype that is studied may be markedly different according to the diagnostic system used.
