Post-traumatic stress disorder in peacekeepers: a systematic literature review and meta-analysis.

Background: In peacekeeping operations, soldiers are often exposed to the same traumatic factors as in conventional war and may also be subject to physical risks and psychological stressors associated with post-traumatic stress disorder (PTSD). According to the Conservation of Resources Theory (COR), PTSD stems from resource depletion and inadequate restoration.Objectives: To discuss and meta-analyse PTSD-related factors among peacekeepers, based on the COR theory, framing them as resources or loss/threat of loss of resources.Methods: A systematic literature search was performed with relevant keywords, 51 articles were reviewed and 21 of them meta-analysed.Results: Factors mentioned in prior reviews, reinforced by ours, include: family/community and military support as resources; single marital status, female gender, serving in infantry, and longer time since deployment as lack of resources. Factors mentioned in prior reviews, confirmed by our meta-analysis, include: education, rank, and problem-focused coping as resources; negative perceptions about deployment, combat/trauma exposure, deployment stressors, and deployment duration as lack of resources. Factors overlooked in prior reviews include: age as a resource; negative life events, and negative social interactions as lack of resources. Comorbidities include: physical health problems, post-deployment impact on functioning, and post-deployment psychopathology (e.g., depression, substance use).Conclusions: Significantly more individual than contextual factors were identified. While some factors inherent to missions (e.g., combat exposure, deployment stressors) cannot be mitigated, others are crucial to prevent peacekeepers' PTSD (e.g., coping strategies, deployment duration, perceptions about deployment, social interactions, support during deployment) and to inform selection and monitoring by the Armed Forces (e.g., pre-, during and post-deployment psychopathology). However, the findings should be interpreted with caution due to limitations (e.g., publication bias, study heterogeneity) that may have affected the generalizability and strength of the recommendations.

This study discusses and meta-analyses PTSD-related factors among peacekeepers, based on the Conservation of Resources Theory, framing them as resources or loss/threat of loss of resources.Identified resources include: family/community and military support; education, rank, problem-focused coping; age.Identified lack of resources include: single marital status, female gender, serving in infantry, longer time since deployment; negative perceptions about deployment, combat/trauma exposure, deployment stressors, deployment duration, negative life events, negative social interactions.

UN peacekeeper health and risk factors --- a systematic scoping review.

BACKGROUND: Conflicts, natural disasters, and complex emergencies present substantial health challenges to United Nations (UN) peacekeepers deployed in mission areas. This scoping review aims at summarizing previous research on the health of UN peacekeepers and identifies issues for further investigation. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Reviews, we systematically searched Web of Science, PubMed, EMBASE, Scopus and China National Knowledge Infrastructure (CNKI) for English and Chinese literature published from April 1997 to November 2023. A data charting form was developed by two reviewers to extract relevant themes and provided narrative descriptions. RESULTS: We screened 1079 de-duplicated records and included 143 studies in this scoping review. There were 112 studies on the health status of UN peacekeepers, with more than half on mental health problems such as stress and anxiety. Many studies explored the health status of UN peacekeepers in African countries deployed from mainly U.S., Canada, U.K., China, Australia and Norway. There were 39 studies on the health risk factors of UN peacekeepers, including natural environmental, social environmental, psychological, behavioral lifestyle, biological factors and health service factors. There were 62 articles on the health protection of UN peacekeepers, mainly based on previous deployment experience, with a lack of theoretical guidance from global health perspectives. This scoping review found that health problems of UN peacekeepers are complicated, and whose impacts are cross-border. Social environmental factors were explored the most among health risk factors. Disease prevention measures, medical and health measures, and psychosocial measures were the main health protection for UN peacekeepers. CONCLUSIONS: This scoping review highlighted that health problems of UN peacekeepers were typical global health issues with complicated and cross-border health risk factors. Therefore, comprehensive strategies could be taken from global health perspectives, including multi-phases (before-deployment, during-deployment, and post-deployment), multi-disciplines (public health, medicine, politics, health diplomacy, and others), and multi-levels (the UN, host countries, troop-contributing countries, the UN peacekeeping team, and UN peacekeepers).

How do you see me? The impact of perceived societal recognition on PTSD symptoms amongst Norwegian peacekeepers.

Background: The peacekeeper role is different to that of traditional combat, however, peacekeepers, like combat soldiers, may also be exposed to high levels of dangerous and/or potentially morally injurious events (PMIEs).Objective: It was hypothesized that given the centrality of societal approval for the peacekeeping mission, in addition to the known relevance of perceived social support, perceived societal recognition would influence PTSD symptoms (PTSS) and depression. It was hypothesized that perceived societal recognition would moderate the effect of exposure to potentially traumatic events and PMIEs on psychological outcomes.Method: 8341, predominantly male, former UNIFIL peacekeepers, almost three decades following deployment, answered a survey to determine the impact of perceived social support and perceived societal recognition, on PTSS and depression symptoms. Hierarchical regression analyses were performed for PTSS and depression separately and moderation analysis was performed for perceived societal recognition.Results: Exposure to potentially traumatic events showed the greatest predictive value for PTSS and exposure to PMIEs and potentially traumatic events were equally predictive of depression symptoms. While perceived social support presented the strongest buffer for PTSS and depression symptoms following UNIFIL deployment, perceived societal recognition also significantly contributed to the prediction of both PTSS and depression symptoms. There was a weak moderation effect of perceived societal recognition on trauma type in the development of PTSS.Conclusions: Even decades following peacekeeping deployment, military experiences have a significant impact on psychological functioning. This impact is both from the types of events experienced and from the perception of social and societal support upon return home.

Peacekeepers receive little attention in general military research and their missions are often directly influenced by public perception.The current study found that key military traumas; danger based and moral injury based events, were prevalent in the peacekeeper population and predicted PTSD symptoms and depression symptoms respectively.While there was a weak moderation effect, perceived societal recognition was a unique predictor of PTSD symptoms. Those who perceived negative levels of societal recognition of the UNIFIL mission had greater PTSD symptoms than those who perceived neutral or positive levels of societal recognition.

Developing a conceptual framework for the health protection of United Nations peacekeepers against the COVID-19 pandemic from global health perspectives.

The coronavirus disease 2019 (COVID-19) pandemic has posed particular health risks to United Nations peacekeepers, which require prompt responses and global attention. Since the health protection of United Nations peacekeepers against the COVID-19 pandemic is a typical global health problem, strategies from global health perspectives may help address it. From global health perspectives, and referring to the successful health protection of the Chinese Anti-Ebola medical team in Liberia, a conceptual framework was developed for the health protection of United Nations peacekeepers against the COVID-19 pandemic. Within this framework, the features include multiple cross-borders (cross-border risk factors, impact, and actions); multiple risk factors (Social Determinants of Health), multiple disciplines (public health, medicine, politics, diplomacy, and others), and extensive interdepartmental cooperation. These strategies include multiple phases (before-deployment, during-deployment, and post-deployment), multi-level cooperation networks (the United Nations, host countries, troop-contributing countries, the United Nations peacekeeping team, and United Nations peacekeepers), and concerted efforts from various dimensions (medical, psychological, and social).

Potentially traumatic events and post-traumatic growth among Chinese peacekeepers: A moderated mediation model.

Peacekeepers are inherently exposed to potentially traumatic events (PTEs) in the line of duty. However, little is known about whether PTEs during peacekeeping missions may foster post-traumatic growth (PTG) among peacekeepers and its mechanisms. This study aimed to investigate the association between PTEs and PTG among Chinese peacekeepers, as well as the mediating role of coping style and the moderating role of resilience. Five hundred ninety-five Chinese peacekeepers completing the United Nations (UN) peacekeeping mission in South Sudan and returning to China were recruited to complete Peacekeeping Traumatic Stress Exposure Scale, Posttraumatic Growth Inventory, Simplified Coping Style Questionnaire and the Chinese version of Connor and Davidson's Resilience Scale. PTEs were positively associated with PTG among Chinese peacekeepers. Coping style partially mediated the association between PTEs and PTG. Resilience moderated the association between coping style and PTG. Specifically, at a lower level of resilience, positive coping style was more effective in predicting PTG. This study contributes to understanding the complex association between PTEs in peacekeeping missions, coping style, resilience and PTG by focusing on the experiences of Chinese peacekeepers and adds value to the current literature on psychological health in peacekeepers.

Development of an Index to Measure the Exposure Level of UN Peacekeeper-Perpetrated Sexual Exploitation/Abuse in Women/Girls in the Democratic Republic of Congo.

Sexual exploitation and abuse (SEA) of women and girls by United Nations (UN) peacekeepers is an international concern. However, the typical binary measurement of SEA (indicating that it occurred, or it did not) disregards varying exposure levels and the complex circumstances surrounding the interaction. To address this gap, we constructed an index to quantify the degree to which local women and girls were exposed to UN-peacekeeper perpetrated SEA. Using survey data (n = 2867) from the Democratic Republic of Congo (DRC), eight indicators were identified using a combination of qualitative (thematic analysis of narrative data) and quantitative variables. With further development, this index may offer a more comprehensive and nuanced perspective of peacekeeper-perpetrated SEA that can better inform SEA prevention and intervention efforts.

A cross-sectional study of community perceptions of stigmatization amongst women affected by UN-peacekeeper perpetrated sexual exploitation and abuse.

BACKGROUND: Sexual exploitation and abuse (SEA) by UN peacekeepers perpetrated against local women and girls is a concern in the Democratic Republic of Congo (DRC). While stigma associated with sexual and gender-based violence is well documented more broadly, little is known about stigma associated with peacekeeper-perpetrated SEA. METHODS: The aim of this study was to examine how the degree of exposure to SEA affects community perceptions of a woman or girl's (1) social status (public stigma) and (2) institutional support in her community (structural stigma). Two poisson regression models with robust variance estimation were constructed utilizing community survey data of SEA experiences from eastern DRC (n = 2867) to quantify these associations. Relevant demographic variables were assessed for confounding and effect modification. RESULTS: The prevalence of public and structural stigma were 62.9 and 19.3% respectively across the sample. A positive relationship was demonstrated between level of exposure of SEA and diminished social status in which women and girls experiencing moderate levels of SEA were at the greatest risk of public stigmatization after adjusting for confounding (RR: 1.94; CI: 1.66-2.26). Similarly, a positive relationship between exposure to SEA and inadequate institutional support was shown for female narrators wherein women and girls experiencing a high degree of SEA were 6.53 times as likely to receive inadequate support (RR: 6.53; CI: 3.63, 11.73). This contrasted with male narrated stories for whom there was no significant association between the SEA exposure level and institutional support. CONCLUSIONS: Women/girls with high exposure levels to UN peacekeeper-perpetrated SEA are at the highest risk of public and structural stigmatization, which should be more routinely considered when conceptualizing the consequences of SEA in peacekeeping contexts. The frequent occurrence of both public and structural stigma, coupled with the varying perceptions by sex, demonstrates the need for a multi-faceted approach for stigma reduction.

A Review of Supplementary Medical Aspects of Post-Cold War UN Peacekeeping Operations: Trends, Lessons Learned, Courses of Action, and Recommendations.

Post-Cold War United Nations Peace Keeping Operations (UN PKOs) have been increasingly involved in dangerous areas with ill-defined boundaries, harsh and remote geographies, simmering internecine armed conflict, and disregard on the part of some local parties for peacekeepers' security and role. In the interest of force protection and optimizing operations, a key component of UN PKOs is healthcare and medical treatment. The expectation is that UN PKO medical support will adjust to the general intent and structure of UN PKOs. To do so requires effective policies and planning informed by a review of all medical aspects of UN PKO operations, including those considered supplementary, that is, less crucial but contributing nonetheless. Medical aspects considered paramount and key to UN PKOs have received relatively thorough treatment elsewhere. The intent of this article is to report on ancillary and supplemental medical aspects practical to post-Cold War UN PKO operations assembled through an iterative inquiry of open-source articles. Recommendations are made about possible courses of action in terms of addressing trends found in such medical aspects of PKOs and relevance of US/NATO/European Union models and research.

Post-cold war United Nations peacekeeping operations: a review of the case for a hybrid level 2+ medical treatment facility.

Post-Cold War, UN peacekeeping operations (UN PKOs) have become larger, more mobile, multi-faceted and conducted over vast areas of remote, rugged, and harsh geography. They have been increasingly involved in dangerous areas with ill-defined boundaries, simmering internecine armed conflict, and disregard on the part of some local parties for peacekeepers' security and role. Yet progressively there have been expectations of financial restraint and austerity. Additionally, UN PKOs have become more "robust," that is, engaged in preemptive, assertive operations. A statistically positive and significant relationship exists between missions' size, complexity, remoteness, and aggressive tenor and a higher probability of trauma or death, especially as a result of hostile actions or disease. Therefore, in the interest of "force protection" and optimizing operations, a key component of UN PKOs is health care and medical treatment. The expectation is that UN PKO medical support must conform to the general intent and structure of current UN PKOs to become more streamlined, portable, mobile, compartmentalized, and specialized, but also more varied and complex to address the medical aspects of these missions cost-efficiently. This article contends that establishing a hybrid level 2-a level 2 with level 3 modules and components (i.e., level 2+)-is a viable course of action when considering trends in the medical aspects of Post-Cold War UN PKOs. A level 2 medical treatment facility has the potential to provide needed forward mobile medical treatment, especially trauma care, for extended, complex, large-scale, and comprehensive UN PKOs. This is particularly the case for missions that include humanitarian outreach, preventive medicine, and psychiatry. The level 2 treatment facility is flexible enough to expand into a hybrid level 2+ with augmentation of modules based on changes in mission requirements and variation in medical aspects.
