Psychological symptoms as long-term consequences of war experiences

Psychotic and Somatic Symptoms Are Frequent in Refugees With Posttraumatic Stress Disorder: A Narrative Review

OBJECTIVE

In 2021, 89.3 million refugees were vulnerable to posttraumatic stress disorder (PTSD) after exposure to multiple and repeated traumatic experiences. The recent war in Ukraine provoked 7 million refugees to flee their homes. Specific clinical presentations of PTSD in refugee populations may not be familiar to most physicians. The goal of this review is to describe the diagnosis and specific clinical features of PTSD in refugees.

METHODS

This narrative review of 263 articles explores 3 PTSD diagnoses that are frequently described in refugee populations and that have been observed in our clinical practices: complex PTSD, PTSD with psychotic symptoms, and PTSD with somatic symptoms.

RESULTS

While complex PTSD does not seem to be related to individuals' culture and origin, the other 2 diagnoses have been specifically described in refugee populations. PTSD with somatic manifestations appears to be the most frequently described and commonly acknowledged form in refugee populations, whereas PTSD with psychotic symptoms remains more controversial due to its clinical variability and association with comorbid disorders.

CONCLUSIONS

The difficulty of identifying PTSD with psychotic symptoms and PTSD with somatic symptoms in refugee populations may lead to misdiagnosis and explain the moderate effectiveness of care delivered to these populations. Appropriate diagnosis is essential to provide optimal psychiatric care to refugee populations.

Increased social identification is linked with lower depressive and anxiety symptoms among ethnic minorities and migrants: A systematic review and meta-analysis

Evidence suggests that social identities, which provide purpose and a sense of belonging to the social world, promote resilience against psychological strain and protect well-being. This is especially important in ethnic minorities, who experience exclusion and discrimination from the majority group, and in migrant populations where adverse experiences, such as prejudice, disconnection from previous identities and issues of integration into the host country, negatively impact well-being. Drawing from the social identity theory, a meta-analysis was conducted examining the influence of group memberships and sense of belonging on ethnic minority and migrant mental health (depression and anxiety). The final search on three databases (i.e., PubMed, PsycINFO, Web of Science) was conducted on August 9th, 2022, identifying 3236 citations before removing any duplicates within and between databases. Across the 74 studies that met the inclusion criteria for the meta-analysis, increased social identification (ethnic, national and other types of identification) was associated with low psychological symptoms. We found that social identification is protective against common psychological disorders but with small effect sizes for depression (r = - 0.09, CI = [- 0.12; - 0.06]) and anxiety (r = - 0.08, CI [- 0.12; - 0.03]). Results are discussed with regard to the role that social context plays on ethnic minority and migrant mental health and the importance of facilitating migrant integration with the host society after displacement.

Mental health outcomes in Syrian refugees: A systematic review

BACKGROUND

Syria is the main country of origin for refugees in the world. The prevalence of mental disorders in this population is high, but there is a lack of more comprehensive data on mental health issues in this population.

AIM

This study aims to review the literature for mental health outcomes in Syrian refugees.

METHODS

We performed a systematic quantitative literature review of original observational studies indexed on the MEDLINE via PubMed, Embase, Web of Science, PsycINFO, LILACS, and SciELO databases with quantitative data reporting mental health outcomes in Syrian refugees. A descriptive analysis was conducted, and the quality of the included studies was assessed using an adaptation from The National Institutes of Health (NIH) quality assessment tool for observational studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed.

RESULTS

A total of 64 studies were included. The majority were published between 2019 and 2020, and focused on the prevalence of post-traumatic stress disorder (PTSD), depression, and anxiety, with a wide range of variations. Other outcomes were difficulties in the post-migration period and promotive factors for mental health, such as resilience, positive coping strategies, and psychosocial well-being.

CONCLUSIONS

High prevalence rates of mental disorders were observed, as well as risk factors for their occurrence. Studies showed a very high variability of prevalence rates and heterogeneity in methodologies. There is a need for research focusing on other determinants and specific necessities for mental health, especially in the post-resettlement period.

‘We are inferior, we have no rights’: Statelessness and mental health among ethnic minorities in Northern Thailand

Research has shown that asylum seekers, refugees, and internally displaced persons, including stateless persons, are at increased risk of poor mental health. Yet, only a few studies explicitly focus on stateless persons. This article examines the association between legal status and mental health among Akha, Lahu and Tai-Yai people in Northern Thailand. A convergent parallel mixed-methods design was adopted and primary data were collected in June 2020 by face-to-face, semi-structured interviews with persons who do not hold a nationality (n = 108). A distinction was made between registered (nationalityless) and unregistered (stateless) persons since only the former have a legal status in Thailand. The correlates of mental health were analyzed using descriptive statistics and logistic regression. Qualitative thematic analysis was employed to gain deeper insights into the relationship between legal status, ethnicity and mental health. The quantitative results weakly suggest that stateless persons are more likely to have poorer mental health than nationalityless persons, who are recognized as habitually resident in Thailand and are recorded in the country's civil registry. The qualitative results, however, show that the legal status afforded to nationalityless persons is considered important as it gives rise to hope and increases livelihood opportunities. Yet, respondents also pointed out that it is not comparable to citizenship. The odds of having poorer mental health are significantly higher for Lahu and Tai-Yai respondents. The importance of ethnicity is confirmed by the qualitative results. These further indicate that citizenship problems and ethnicity are deeply interrelated. Stigma, discrimination, and lack of social support are key risk factors identified by respondents. Disaggregating data to better understand the heterogeneity of persons without nationality could play a key role in accelerating efforts to resolve protracted citizenship problems and close ethnic gaps.

•

Legal recognition and ethnicity affect the mental health of persons without nationality.

•

Stigma, discrimination, and lack of social support are key risk factors.

•

Disaggregated data are essential for identifying and addressing existing gaps.

Mental health and psychosocial support in conflict: children's protection concerns and intervention outcomes in Syria

Child protection and mental health during conflict intersects with a variety of adverse conflict-related factors, and intervention outcomes in the field are often difficult to predict. Using the casefiles of 376 school children registered in a Mental Health and Psychosocial Support (MHPSS) project in the Northwest governorate of Idleb in Syria, this study aimed to determine (i) the rates of various protection concerns (potential mental health conditions, psychosocial deprivation issues, and social, behavioural and emotional issues) for students enrolled in this project, (ii) whether the rates of any of the protection concerns varied between children and adolescents, or between boys and girls, and (iii) which of the identified demographic and protection sector factors predicted the presence of potential mental health conditions and MHPSS intervention outcomes. MHPSS interventions (including individual MHPSS sessions tailored for children in conflict, resilience building activities, tutoring, peer building activities, community awareness, and other tailored services) were implemented at schools operated by the UK-based organization, Syria Relief. The variables tested included demographic variables of age group (208 children, aged 4-9 years; 168 adolescents, aged 10-14 years) and gender (211 males, 165 females), and 23 protection sector variables including 11 potential mental health problems (anxiety, attention deficit hyperactivity disorder, conduct disorder, autism, epilepsy, motor tics, depression, post-traumatic-stress disorder, social phobia, specific phobia, learning disability), 7 psychosocial deprivation (PSD) variables (war injury, child labour, loss of caregiver, neglect, domestic abuse, displacement, poverty), and 5 social, behavioural and emotional (SBE) variables (low/abnormal socialization, emotional issue, peer issues/being bullied, peer issues/being aggressive, educational decline). Within the sample, 73.7% were found with a probable mental health problem, with 30.6% showing signs of anxiety, 36.2% of depression and 26.6% showing signs of post-traumatic-stress disorder. Additionally, 74.5% of the sample had at least one form of PSD present (42.6% were displaced, 39.6% suffered from abject poverty), and 64.9% had a reported SBE concern. Children were more likely to have a potential mental health concern, especially autism and PTSD, and poor socialization; while adolescents were more likely to engage in child labour, experience abject poverty, exhibit aggressive behaviour, and educational decline. Male gender was associated with child labour and aggressive behaviour while female gender was associated with the presence of potential mental health problems, especially depression, and loss of caregiver, and poor socialisation. Odds ratios (ORs) indicated significant negative impact of the presence of SBE concerns (any), 4.45 (95% CI: 1.68-12.7), emotional issue, 11.02 (95% CI: 2.76-74.49), low/abnormal socialization, 8.37 (95% CI, 2-57.71), and displacement, 2.91 (95% CI, 1.21-7.48) on the child's mental health. MHPSS intervention outcomes were categorized as case improvement, decline, or incomplete/limited information available; with case improvement noted for 63.6% of the sample, decline noted for 14.4%, and incomplete treatment/limited follow-up noted for 22.1% of the sample. Additional analysis of predictors of treatment success found that child labour was significantly associated with a lack of treatment success, OR 0.24 (95% CI, 0.07-0.92). These findings provide important insights into the complex tailoring needs that protection and MHPSS field projects require.

A Systematic Review of Factors Affecting Mental Health and Well-Being of Asylum Seekers and Refugees in Germany

Background: Since the onset of the 2015 European refugee crisis, ~4. 46 million people have sought asylum in the European Union, with Germany logging the largest share of all asylum applications. In addition to the severe adversities before and during flight, the process of settling into a new environment involves stressors that affect psychological well-being and mental health. The aim of this systematic review was to examine contextual factors during post-migration that influence the mental health and well-being of asylum seekers and refugees (ASRs) in Germany. Methods: Following PRISMA guidelines, a systematic review was conducted across multiple databases for English and German studies published between 2015 and 2020 with index keywords. Results: From a total of 303 articles, 156 duplicates were removed and, after title review, another 87 were excluded for not meeting the inclusion criteria. After assessing the abstracts of the remaining 60 articles, 39 were excluded. Full texts of 21 articles were assessed for eligibility and after excluding 8 articles, 13 articles were included in the review. The results demonstrate high rates of psychological distress among ASRs in Germany and the significant influence of contextual factors on their mental health and psychological well-being. The risk factors for poor mental health include an uncertain asylum status, living in shared asylum accommodations, separation from the nuclear family, lack of German language skills, integration issues and discrimination, while employment is a protective factor. Conclusion: Asylum seekers and refugees have high prevalence rates of psychological distress directly influenced by contextual factors in Germany. Based on these findings, policy makers are strongly recommended to apply preventive strategies to reduce mental health problems of ASRs in Germany.

Venir de loin et se retrouver : intervention de groupe pour femmes immigrantes et réfugiées ayant vécu la violence

Objectifs Cet article a une visée clinique et présente une intervention novatrice pouvant être offerte dans différents milieux de pratique. Il est question ici d’une intervention de groupe s’adressant plus spécifiquement à des femmes immigrantes et réfugiées qui ont vécu différentes formes de violence. Les répercussions de l’exposition à la violence intentionnelle et déshumanisante, jumelées aux défis liés à la migration et à l’exil forcé, peuvent fragiliser les individus et mettre à l’épreuve leurs capacités d’adaptation. Bien que le soutien psychologique et psychosocial au cours des années qui suivent leur arrivée peut s’avérer salutaire, les personnes immigrantes et réfugiées ont peu recours aux services institutionnels, et des experts pointent le manque d’adéquation des services offerts à cette population. Il s’avère donc indispensable de promouvoir le développement d’interventions plus signifiantes pour ces personnes, en vertu du principe d’équité et d’égalité des chances d’accès à des services adéquats, mais aussi pour mieux outiller les intervenants en leur fournissant des interventions sécuritaires et culturellement sensibles. C’est dans cette perspective qu’a été élaborée en 2010 une intervention de groupe pour des femmes immigrantes et réfugiées ayant vécu la violence, fruit d’une collaboration entre des chercheuses de l’IUPLSSS et des intervenantes du CIUSSS de l’Estrie-Chus.

Méthode Cet article vise en premier lieu à présenter cette intervention de groupe. Il sera notamment question de son caractère novateur ainsi que du rationnel clinique et empirique qui sous-tend le choix de ses principales composantes, soit le format de groupe et les modalités artistiques. S’ensuivra une description plus détaillée de l’intervention quant à ses objectifs, son déroulement et certaines composantes essentielles pour assurer sa portée thérapeutique et l’établissement d’un espace sécuritaire. En second lieu, l’article présente brièvement les données préliminaires d’une étude en cours visant notamment à évaluer les retombées de cette intervention. Dans le cadre de cette étude, des données qualitatives et quantitatives ont été recueillies auprès de 3 groupes (n = 17) et soumises à des analyses de contenu et des analyses quantitatives non paramétriques pour mesurer les changements entre le pré et posttest.

Résultats En ce qui concerne plus spécifiquement l’étude en cours, les résultats préliminaires des analyses qualitatives et quantitatives montrent que les femmes ayant participé aux groupes rapportent à la fin de l’intervention une diminution des symptômes de stress posttraumatique de même que des améliorations sur différentes dimensions de leur bien-être.

Conclusion La conclusion met en exergue les avantages et les limites de cette intervention, mais aussi sa pertinence pour les milieux de pratique. Bien que n’étant pas l’unique réponse pour intervenir en contexte interculturel et postviolence, cette intervention représente une option de choix pour octroyer des services adaptés à la réalité et aux besoins de personnes immigrantes et réfugiées.

Systematic review and meta-analyses of the long-term efficacy of narrative exposure therapy for adults, children and perpetrators

Objective: Narrative Exposure Therapy (NET) is a short-term trauma-focused intervention originally developed for treating survivors of war and torture. The neurobiological theoretical foundations of NET would suggest that the approach should have long term beneficial effects. We tested this assumption and also provided an extensive overview of all NET studies for adults, for children (KIDNET), and for perpetrators (Forensic Offender Rehabilitation NET; FORNET).Method: Following a systematic literature review, we conducted meta-analyses with all studies that had control conditions, and with all Randomized Controlled Trials (RCTs). We assessed between-groups short- (< 6 months) and long-term (≥ 6 months) effect sizes for symptoms of posttraumatic stress disorder (PTSD) and depression.Results: In a total of 56 studies from 30 countries comparing 1370 participants treated with NET to 1055 controls, we found large between group effect sizes regarding the reduction of PTSD symptoms in favor of NET. Analyses of RCTs with active controls yielded small to medium effect sizes in the short-term, and large effect sizes in the long-term.Conclusions: NET, KIDNET, and FORNET yield beneficial and sustainable treatment results for severely traumatized individuals living in adverse circumstances. Studies in highly developed health care systems comparing NET with other evidence-based trauma-focused interventions are needed.

Trauma, Aggression, and Post Conflict Perpetration of Community Violence in Female Former Child Soldiers-A Study in Eastern DR Congo

OBJECTIVE

Former combatants are exposed to multiple traumatic stressors during conflict situations and usually participate in perpetration of violence. Ongoing perpetration of violence in post conflict areas, linked to mental health problems and appetitive aggression, destabilises peace keeping efforts. The aim of this study is to investigate lifetime exposure to violence and the relationship between this exposure and mental health and current violent behaviour in a sample of female former child soldiers with a history of perpetration of violence in Eastern DR Congo.

METHODS

98 female former child soldiers who had been abducted and forcibly recruited during the M23 insurgency (2012-2014) were assessed for lifetime exposure to trauma including perpetration of violence, clinical outcomes (PTSD and appetitive aggression), and current violent behaviour.

RESULTS

Female former child soldiers had been exposed to extremely high levels of trauma including perpetration of violence and presented with high levels of mental health problems. Linear regression models showed that current violent behaviour was predicted by both PTSD and appetitive aggression.

CONCLUSIONS

Trauma exposure predicts ongoing perpetration of violence post conflict via the resulting mental health problems. The findings imply that if PTSD and appetitive aggression symptoms are successfully treated, ongoing violent behaviour in the community post conflict will also decrease.

Psychological, social, and welfare interventions for torture survivors: A systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Torture and other forms of ill treatment have been reported in at least 141 countries, exposing a global crisis. Survivors face multiple physical, psychological, and social difficulties. Psychological consequences for survivors are varied, and evidence on treatment is mixed. We conducted a systematic review and meta-analysis to estimate the benefits and harms of psychological, social, and welfare interventions for torture survivors.

METHODS AND FINDINGS

We updated a 2014 review with published randomised controlled trials (RCTs) for adult survivors of torture comparing any psychological, social, or welfare intervention against treatment as usual or active control from 1 January 2014 through 22 June 2019. Primary outcome was post-traumatic stress disorder (PTSD) symptoms or caseness, and secondary outcomes were depression symptoms, functioning, quality of life, and adverse effects, after treatment and at follow-up of at least 3 months. Standardised mean differences (SMDs) and odds ratios were estimated using meta-analysis with random effects. The Cochrane tool was used to derive risk of bias. Fifteen RCTs were included, with data from 1,373 participants (589 females and 784 males) in 10 countries (7 trials in Europe, 5 in Asia, and 3 in Africa). No trials of social or welfare interventions were found. Compared to mostly inactive (waiting list) controls, psychological interventions reduced PTSD symptoms by the end of treatment (SMD -0.31, 95% confidence interval [CI] -0.52 to -0.09, p = 0.005), but PTSD symptoms at follow-up were not significantly reduced (SMD -0.34, 95% CI -0.74 to 0.06, p = 0.09). No significant improvement was found for PTSD caseness at the end of treatment, and there was possible worsening at follow-up from one study (n = 28). Interventions showed no benefits for depression symptoms at end of treatment (SMD -0.23, 95% CI -0.50 to 0.03, p = 0.09) or follow-up (SMD -0.23, 95% CI -0.70 to 0.24, p = 0.34). A significant improvement in functioning for psychological interventions compared to control was found at end of treatment (SMD -0.38, 95% CI -0.58 to -0.18, p = 0.0002) but not at follow-up from only one study. No significant improvement emerged for quality of life at end of treatment (SMD 0.38, 95% CI -0.28 to 1.05, p = 0.26) with no data available at follow-up. The main study limitations were the difficulty in this field of being certain of capturing all eligible studies, the lack of modelling of maintenance of treatment gains, and the low precision of most SMDs making findings liable to change with the addition of further studies as they are published.

CONCLUSIONS

Our findings show evidence that psychological interventions improve PTSD symptoms and functioning at the end of treatment, but it is unknown whether this is maintained at follow-up, with a possible worsening of PTSD caseness at follow-up from one study. Further interventions in this population should address broader psychological needs beyond PTSD while taking into account the effect of multiple daily stressors. Additional studies, including social and welfare interventions, will improve precision of estimates of effect, particularly over the longer term.

Long-term psychological distress of Bosnian war survivors: an 11-year follow-up of former displaced persons, returnees, and stayers

BACKGROUND

Research on the long-term mental health consequences of war and displacement among civilians who live in post-conflict countries is rare. The aim of this study was to examine the developmental trajectories and predictors of general psychological distress in three samples of Bosnian war survivors over an 11-year period.

METHODS

In 1998/99, about three years after the war in Bosnia and Herzegovina, a representative sample of 299 adult Sarajevo citizens was examined in three subsamples: individuals who had stayed in Sarajevo throughout the siege, individuals who had been internally displaced, and refugees who had returned. Of the 138 study participants who could be located 11 years later, 100 were re-assessed (71%) using the Brief Symptom Inventory.

RESULTS

Over time, psychological symptoms and general psychological distress decreased in those survivors who had stayed and increased in returnees. Former displaced persons did not show any significant changes. After controlling for other factors, cumulative trauma exposure before and during the war predicted general psychological distress at baseline. Eleven years later, higher trauma exposure during and after the war, returnee status, and more current stressors were all associated with higher levels of general psychological distress.

CONCLUSIONS

Levels of psychological symptoms remained high in three subsamples of Bosnian war survivors. The differential symptom trajectories may correspond to distinct war experiences and contemporary stressors. Still, the cumulative effect of war traumata on mental distress persisted more than a decade after war and displacement, although the influence of current stressors seemed to increase over time.

Post-migration treatment targets associated with reductions in depression and PTSD among survivors of torture seeking asylum in the USA

Mental health research among asylum seekers and refugees has largely focused on effects of pre-migration trauma on post-migration wellbeing. While emerging literature highlights the importance of post-migration factors, we do not yet understand how addressing these factors may influence change in psychological distress. This study uses archival clinical data to identify post-migration correlates of reductions in distress among torture survivors, after accounting for pre-migration trauma. Depression (Patient Health Questionnaire-9) and Post Traumatic Stress Disorder (PTSD; Harvard Trauma Questionnaire) were measured among torture survivors following 6 months of interdisciplinary treatment (N = 323). Relationships between pre-, post-migration factors, and changes in symptom levels from intake to six months follow-up, were evaluated using regression analyses. Average levels of depression and PTSD significantly reduced after six months of treatment. Higher exposure to pre-migration trauma, female gender, and change to a more secure visa status were associated with reduced distress. Accessing more social services and not reporting chronic pain were associated with reduced PTSD. Stable housing and employment significantly moderated the relationship between lower chronic pain and reduced PTSD. Although effect sizes were small, results emphasize the importance of post-migration factors on wellbeing among torture survivors and are a first step towards identifying key treatment targets.

Posttraumatic Stress Disorder and Psychiatric Co-morbidity among Syrian Refugees of Different Ages: the Role of Trauma Centrality

It has been documented that trauma centrality is associated with posttraumatic stress disorder (PTSD) and psychiatric co-morbidity among Syrian refugees. Whether age would influence the levels of the above constructs and the association between trauma centrality and distress outcomes is unclear. This study compared age differences in 1) the levels of trauma centrality, posttraumatic stress disorder and psychiatric co-morbidity, and 2) models depicting the association between trauma centrality and distress outcomes among Syrian refugees. One thousand one hundred and ninety-seven refugees completed the Centrality of Event Scale, Harvard Trauma Questionnaire and General Health Questionnaire-28. Age groups were divided into young, middle-aged adults and adults of 45 or above. No significant group differences were found in the proportion of refugees meeting the diagnostic criteria for PTSD. Controlling for demographic variables, all subscales of trauma centrality and psychiatric co-morbidity were significantly different between groups. Young adults reported significantly less trauma centrality and psychiatric co-morbidity than the other groups. Multiple-indicator multiple-cause modelling showed that trauma centrality was significantly correlated with PTSD and psychiatric co-morbidity. Multi-group analysis showed the model for the young adult group to be significantly different from the middle-aged group model. To conclude, age did not seem to influence the severity of PTSD among Syrian refugees. The war had a less severe impact on young adults' sense of self and other psychological problems than those who were older. The way in which young and middle-aged adults responded to distress varied depending on environment and personal characteristics.

The Relationship between Exposure to Missiles and PTSD Symptoms as a Function of Hemispheric Preference in Israelis

Recent research proposes that left hemispheric lateralization (HL) may protect against the effects of life events on mental distress. This study extends these findings by examining the protective role of left HL in the relationship between war threat (missile exposure) and PTSD symptoms. A sample of 186 Israelis, exposed to missile attacks, completed brief scales of self-reported missile exposure, a subjective and a neuropsychological HL measure, and of PTSD symptoms. The sample was split into right HL and left HL individuals on both HL measures. Self-reported missile exposure was positively associated with PTSD symptoms in right HL, but not in left HL individuals on both HL measures. These results replicate, extend our previous results and suggest that left HL may even protect against the effects of severe life threatening events. Results are discussed in relation to neuropsychological and neurophysiological differences between the hemispheres.

Prevalence of and risk factors for mental disorders in refugees

Given the increasing numbers of refugees worldwide, the prevalence of their mental disorders is relevant for public health. Prevalence studies show that, in the first years of resettlement, only post-traumatic stress disorder (PTSD) rates are clearly higher in refugees than in host countries' populations. Five years after resettlement rates of depressive and anxiety disorders are also increased. Exposure to traumatic events before or during migration may explain high rates of PTSD. Evidence suggests that poor social integration and difficulties in accessing care contribute to higher rates of mental disorders in the long-term. Policy and research implications are discussed.

The mental health of civilians displaced by armed conflict: an ecological model of refugee distress

Early research on the mental health of civilians displaced by armed conflict focused primarily on the direct effects of exposure to war-related violence and loss. Largely overlooked in this war exposure model were the powerful effects of ongoing stressors related to the experience of displacement itself. An ecological model of refugee distress is proposed, drawing on research demonstrating that mental health among refugees and asylum seekers stems not only from prior war exposure, but also from a host of ongoing stressors in their social ecology, or displacement-related stressors. Implications of this model for addressing the mental health and psychosocial needs of refugees and other displaced populations are considered.

Psychosocial interventions for post-traumatic stress disorder in refugees and asylum seekers resettled in high-income countries: Systematic review and meta-analysis

Treatment of post-traumatic stress disorder (PTSD) in refugees and asylum seekers resettled in high-income countries presents specific challenges. This systematic review examined the effectiveness of psychosocial interventions for this group. We searched the Cochrane Central Register of randomised trials, CINAHL, EMBASE, PILOTS, PsycINFO, PubMed and Web of Science up to July 2016. Studies included randomised and controlled clinical trials comparing psychosocial interventions with waiting list or treatment as usual in adult refugees and asylum seekers with PTSD resettled in high-income countries. PTSD symptoms post-intervention was the primary outcome. We computed standardized mean differences (SMD) with 95% confidence intervals (CI). This study is registered with PROSPERO: CRD42015027843. Twelve studies were included in the meta-analysis. Psychosocial interventions were effective in decreasing PTSD symptoms relative to control groups (SMD -1·03, 95% CI -1·55 to -0·51; number needed to treat 4·4; I2 86%; 95% CI 77 to 91). Narrative exposure therapy, a manualized short-term variant of cognitive behavioural therapy with a trauma focus, was the best-supported intervention (5 RCTs, 187 participants, SMD -0·78, 95% CI -1·18 to -0·38, I2 37%; 95% CI 0 to 77). Methodological quality of the included studies was limited. Overall, psychosocial interventions for asylum seekers and refugees with PTSD resettled in high-income countries were found to provide significant benefits in reducing PTSD symptoms. Yet, the number of studies is small and their methodological quality limited, so that more rigorous trials should be conducted in the future.

Violent Offending Promotes Appetitive Aggression Rather than Posttraumatic Stress-A Replication Study with Burundian Ex-Combatants

Research has identified appetitive aggression, i.e., the perception of committed, violent acts as appealing, exciting and fascinating, as a common phenomenon within populations living in precarious and violent circumstances. Investigating demobilized soldiers in the Democratic Republic of Congo (DRC) demonstrated that violent offending is associated with appetitive aggression and not necessarily with symptoms of posttraumatic stress. In the present study, we sought to replicate these results in an independent and larger sample of demobilized soldiers from Burundi. As with the Congolese ex-combatants, random forest regression revealed that the number of lifetime perpetrated violent acts is the most important predictor of appetitive aggression and the number of lifetime experienced traumatic events is the main predictor for posttraumatic stress. Perpetrated violent acts with salient cues of hunting (pursuing the victim, the sight of blood, etc.) were most predictive for perceiving violent cues appealingly after demobilization. Moreover, the association of violent acts and appetitive aggression as well as traumatic events and posttraumatic stress remains strong even years after demobilization. Patterns of traumatic events and perpetrated acts as predictors for posttraumatic stress and appetitive aggression seem to be robust among different samples of ex-combatants who fought in civil wars. Psychotherapeutic interventions that address these complementary facets of combat-related disorders—namely, posttraumatic stress and appetitive aggression—are indispensable for a successful reintegration of those who fought in armed conflicts and to achieve a successful transition to peace.

A Dream Best Forgotten

Refugees are often forced into states of imposed vulnerability in which loss is common and migration is normative. Karen refugees from Myanmar have endured a long civil war with the Burmese government, followed by their forced relocation to refugee camps and subsequent global resettlement. This phenomenological study aimed to understand the meanings ascribed to pre-resettlement stress among resettled Karen refugees. We interviewed six participants who were identified through purposeful sampling in a Karen refugee community. Using phenomenological analysis, we identified and interpreted 286 meaning units. The meaning units were then grouped into four themes: (a) Loss From Oppression, (b) Resignation and Acceptance in a Context of Regular Violence, (c) Ongoing Insecurity While Confined in Camps, and (d) Redefined Selfhood. The results provide a contextual understanding of the pre-resettlement stressors experienced by Karen refugees.

Combat high or traumatic stress: violent offending is associated with appetitive aggression but not with symptoms of traumatic stress

Former members of armed groups in eastern DR Congo had typically witnessed, experienced, and perpetrated extreme forms of violence. Enhanced trauma-related symptoms had been shown in prior research. But also lashing out in self-defense is a familiar response to threat defined as reactive aggression. Another potential response is appetitive aggression, in which the perpetration of excessive violence is perceived as pleasurable (combat high). What roles do these forms of aggressive behavior play in modern warfare and how are they related to posttraumatic stress symptoms? To answer the question, we sought to determine predictors for appetitive aggressive and trauma-related mental illness, and investigated the frequency of psychopathological symptoms for high- and low-intensity conflict demobilization settings. To this end, we interviewed 213 former members of (para)military groups in the eastern Democratic Republic of Congo in regard to their combat exposure, posttraumatic stress, appetitive aggression, depression, suicidality, and drug dependence. Random forest regression embedded in a conditional inference framework revealed that perpetrated violent acts are not necessarily stressful. In fact, the experience of violent acts that typically implicated salient cues of hunting (e.g., blood, suffering of the victim, etc.) had the strongest association with an appetite for aggression. Furthermore, the number of lifetime perpetrated violent acts was the most important predictor of appetitive aggression. However, the number of perpetrated violent acts did not significantly affect the posttraumatic stress. Greater intensity of conflict was associated with more severe posttraumatic stress symptoms and depression. Psychotherapeutic interventions that address appetitive aggression in addition to trauma-related mental illness, including drug dependence, therefore seem indispensible for a successful reintegration of those who fought in the current civil wars.
