Psychosocial response to mass conflict: examining the Adaptation and Development after Persecution and Trauma (ADAPT) model using a newly devised Refugee-Mental Health Assessment Package (R-MHAP) amongst refugees from West Papua.

This research program pursued two inter-related aims: to develop the Refugee-Mental Health Assessment Package (R-MHAP) and to apply it to assess aspects of the Adaptation and Development after Persecution and Trauma (ADAPT) model. The model infers that when the domains of safety/security, bonds/networks, access to justice, roles/identities, and existential meaning are undermined, the risk of mental disorder is increased. An additional aim of this research is to examine the validity of complex-post-traumatic stress disorder (C-PTSD) and intermittent explosive disorder (IED). The studies reported herein as published articles were conducted amongst refugees from West Papua (n=230). Chapter Two reports the development and testing of the core R-MHAP modules. The study supports the psychometric properties and validity of the modules of Traumatic Events (TEs), stressors, psychosocial impacts of conflict, and mental disorders. Chapter Three examines the mental health impacts of conflict-related TEs and adversities. The study found that TE exposure was associated with functional impairment; high exposure to stressors was associated with mental disorder. Chapter Four applies the ADAPT index to assess the psychosocial effects of mass conflict on symptoms of post-traumatic stress disorder (PTSD). The study found that the undermining of the foundations of society by conflict exerted a moderating effect on PTS symptoms. Chapters Five and Six investigate the coherence and correlates of PTSD/C-PTSD and IED, respectively, and associations with the ADAPT pillars of sense of insecurity and injustice, ongoing adversities, and conflict exposure. The data offer preliminary support to the independence of PTSD and IED (but not C-PTSD) in this distinctive cultural group. The generic constellation of C-PTSD may have direct relevance to survivors of extreme interpersonal traumas. Furthermore, the intrusion and avoidance domains of PTSD were associated with the interaction of witnessing murders and injustice. The IED constellation was associated with conditions of long-term displacement and separation experienced by the refugees. The research findings encourage a shift in conceptualization and future approaches in the field of post-conflict and refugee mental health. Development of psychopathology following mass violence may be viewed as a dynamic interplay of bio-psychosocial-cultural-spiritual factors. The implications of these findings are detailed in Chapter Seven

Twelve-month trajectories of depressive and anxiety symptoms and associations with traumatic exposure and ongoing adversities: a latent trajectory analysis of a community cohort exposed to severe conflict in Sri Lanka

We conducted a 12-month follow-up of a population sample of adults from districts (Mannar, Killinochi, Mullaitivu and Jaffna) exposed to high levels of mass conflict in Sri Lanka, the aim of the present analysis being to identify trajectories of depression and anxiety symptoms and their associations with exposure to psychological trauma and ongoing living adversities. The cohort of 1275 adults (response 86%) followed-up in 2015 was a structured subsample drawn from the baseline nationally representative survey conducted in 2014 across 25 districts in Sri Lanka. Interviews were conducted using electronic tablets by field workers applying contextually adapted indices of trauma exposure, ongoing adversities and symptoms of depression and anxiety. Latent transition analysis revealed a three-class longitudinal model from which four composite trajectories were derived, comprising a persistent symptom trajectory (n = 555, 43.5%), an incident or new onset trajectory (n = 170, 13.3%), a recovery trajectory (n = 299, 23.5%) and a persistently low-symptom trajectory (n = 251, 19.7%). Factors associated with both the persistent symptom and incident trajectories were female gender, past trauma exposure and lack of access to health services. Loss of a job was uniquely associated with the persisting trajectory at follow-up. The recovery trajectory comprised a higher proportion of men, older persons and those without risk factors. Our findings assist in translating epidemiologic data into public policy and practice by indicating the importance of stable employment and the provision of healthcare as key factors that may act to reduce anxiety and depressive symptoms in the post-conflict phase. The findings also confirm that women are at high risk of mental distress. Brief screening for trauma exposure in populations with high levels of exposure to mass conflict may assist in defining those at risk of ongoing symptoms of anxiety and depression.We thank Australian National University for providing financial support

Measurement invariance of the Hopkins Symptoms Checklist: A novel multigroup alignment analytic approach to a large epidemiological sample across eight conflict-affected districts from a nation-wide survey in Sri Lanka

Background: The alignment method, a novel psychometric approach, represents a more flexible procedure for establishing measurement invariance in geographically, ethnically, or linguistically diverse samples, especially in large epidemiological surveys. Although the Hopkins Symptoms Checklist (HSCL-25) has been used extensively in the field to assess anxiety and depressive symptoms, questions remain about the comparability of findings when the instrument is applied across regions in large-scale national surveys. Methods: The present study is the first in the field to apply the alignment method to test the structure and measurement invariance of the anxiety and depression dimensions of the HSCL-25 amongst Sri Lankan subpopulations (n = 8456) stratified by geographical regions, levels of past exposure to conflict, and ethnic composition. Results: Multigroup CFA analysis yielded non-converging models requiring substantial modifications to the models. As a result, multigroup alignment analysis was applied and the results supported the bifactorial structure and measurement invariance of the HSCL-25 across eight (severe and moderate) conflict-affected districts. The alignment analysis based on a good-fitting configural model yielded a metric non-invariance of 22.22% and scalar non-invariance of 5.88% (both under the established 25% threshold). The bifactorial model outperformed the tripartite and other models. In comparison to the anxiety items, the depressive items showed higher levels of metric non-invariance across districts. Conclusions: Our findings demonstrate the methodological feasibility of applying the alignment method to test the structure and invariance of the HSCL across ethnically diverse populations living in conflict-affected districts in Sri Lanka. Further studies are needed to examine ethnicity and language factors more criticallyThe Australian National Universit

Heart rate variability and the relationship between trauma exposure age, and psychopathology in a post-conflict setting

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

Psychosocial treatment outcomes of common mental disorders vary widely in persons in low-and middle-income countries affected by humanitarian crises and refugees in high-income countries

This commentary discusses methodological and contextual factors that might account for variations in psychosocial treatment outcomes found in persons in low- and middle-income countries affected by humanitarian crises and refugees. Factors discussed are related to cultural adaptations, content and intensity of treatment, population characteristics and factors related to research design

Assessing the factorial structure and measurement invariance of PTSD by gender and ethnic groups in Sri Lanka: An analysis of the modified Harvard Trauma Questionnaire (HTQ)

The Harvard Trauma Questionnaire (HTQ) remains the most widely used screening measure for post-traumatic stress disorder (PTSD) in the refugee and post-conflict field. The present study is the first to test the factorial structure and measurement invariance of the HTQ according to DSM-5 criteria across gender and ethnic groups in the ethnically diverse society of post-conflict Sri Lanka. The survey sample included 5136 participants (86% response rate) followed up 12 months after a baseline nationally representative survey undertaken in Sri Lanka in 2014. Exposure to conflict-related traumatic experiences (TEs) generating a trauma count (TC), and symptoms of PTSD were assessed using a modified version of the HTQ adapted to the local context. The final analytic sample included 4260 participants after excluding records with missing data on key variables. We conducted Multigroup Confirmatory Factor Analysis (MG-CFA) to test the four-factor (DSM-5 consistent) and three-factor (DSM-IV-TR) models of PTSD, then assessing measurement invariance of the four factor model by gender and ethnic groups. The three-factor and four-factor DSM-5 model each produced a good fit across the sample as a whole. In addition, there was configural, metric, and scalar invariance for the four-factor model both by gender and ethnicity. The trauma count was directly associated with each of the symptom domains of the four factor model. Our findings provide support for the capacity of the modified HTQ to measure the DSM5 construct of PTSD across gender and key ethnic groupings in Sri Lanka. Confirmation of our findings in other cultures will be important.The study was funded by The Australian National University

Psychosocial model of burnout among humanitarian aid workers in Bangladesh: role of workplace stressors and emotion coping

Abstract Background While trauma exposure is an established predictor of poor mental health among humanitarian aid workers (HAWs), less is known about the role of psychosocial work-related factors. This study aims to establish a psychosocial model for burnout and psychological distress in HAWs that tests and compares the effects of adversity exposure and workplace stressors in combination, and explores the potential mediating role of individual coping styles. Methods Path analysis and model comparison using cross-sectional online survey data were collected from full-time international and local HAWs in Bangladesh between December 2020 and February 2021. HAWs self-reported on exposure to adversities, workplace psychosocial stressors (Third Copenhagen Psychosocial Questionnaire), coping styles (Coping Inventory for Stressful Situations), burnout (Maslach Burnout Inventory—Human Services Survey), and psychological distress (Kessler-6). Results Among N = 111 HAWs, 30.6%, 16.4%, 12.7%, and 8.2% screened positive for moderate psychological distress (8 ≤ Kessler-6 ≤ 12), emotional exhaustion (EE ≥ 27), depersonalization (DP ≥ 13), and severe psychological distress (K-6 ≥ 13), respectively. 28.8% reported a history of mental disorder. The preferred model showed distinct pathways from adversity exposure and workplace stressors to burnout, with negative emotion-focused coping and psychological distress as significant intervening variables. While greater exposure to both types of stressors were associated with higher levels of burnout and distress, workplace stressors had a stronger association with psychological outcomes than adversity exposure did (β = .52, p ≤ .001 vs. β = .20, p = .032). Workplace stressors, but not adversities, directly influenced psychological distress (β = .45, p ≤ .001 vs. β = −.01, p = .927). Demographic variables, task-focused and avoidance-focused coping were not significantly associated with psychological outcomes. Conclusions Compared to exposure to adversities, workplace stressors primarily influenced occupational stress syndromes. Reducing workplace stressors and enhancing adaptive coping may improve psychological outcomes in humanitarian staff

Prevalence, predictors and associations of complex post-traumatic stress disorder with common mental disorders in refugees and forcibly displaced populations: a systematic review

Background: The inclusion of complex post-traumatic stress disorder (CPTSD) in ICD-11 represents a turning point for the field of traumatic stress, with accumulative evidence of this disorder in refugees and displaced populations. Objective: The objectives of this systematic review are to examine, in refugee and displaced populations: 1) the prevalence of CPTSD; 2) factors contributing to CPTSD; and 3) and associations between CPTSD and other common mental disorders including: PTSD, depression, anxiety and somatisation. Method: We followed the Joanna Briggs Institute Methodology for Systematic Reviews. Papers published in English language were included, with date of publication between 1987 and June 2019. We searched six relevant databases: MEDLINE, PsycINFO, Embase, Scopus, CINAHL, and PILOTS, and the grey literature. We included observational studies with prevalence data on CPTSD. Results: 19 articles met all inclusion criteria. Quality assessment was performed on each included study using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. Based on this, 13 moderate and high-quality studies were included in our narrative synthesis. The included studies reported prevalence of CPTSD in refugees and displaced populations ranging from 2% to 86%. Conclusions: Reasons for the wide variation in prevalence may include contextual and geographical differences, the influence of post-migration difficulties, and sample population characteristics such as treatment seeking versus general population. We found higher prevalence rates (range: 16–82%) in more studies with treatment seeking samples, followed by convenience and snowball samples (40–51%), and lower rates in more studies utilising random sampling techniques (2–86%). Consistent with the broader literature, the studies in our review supported an association for complex post-traumatic stress disorder with prolonged, repeated trauma, and post-migration living difficulties, with the latter association being specific to refugee and displaced populations. Further research on this construct in this population group, including effective treatments, is required
