Mental health of Dutch peacekeeping veterans 10-25 years after deployment

Prevalence and Correlates of Mental Health Problems in Norwegian Peacekeepers 18-38 Years Postdeployment

Peacekeeping missions involve experiences that may impact the mental health of participating soldiers. However, research on the long-term mental health consequences of peacekeeping is sparse. The present study aimed to find the prevalence of mental health problems (MHPs), possible MHP predictors, and associations between predictors and MHPs in Norwegian peacekeepers 18-38 years after deployment to a United Nations peacekeeping mission. We used data from a cross-sectional, postdeployment survey of Norwegian peacekeepers who served in Lebanon between 1978 and 1998 (N = 10,605). Participants were assessed for posttraumatic stress disorder (PTSD); anxiety; depression; insomnia; alcohol misuse; drug misuse; and exposure to pre-, peri-, and postdeployment stressors. Logistic regressions were executed to explore key variables associated with MHPs. Total MHP prevalence was 15.1%, 95% CI [14.4, 15.8]. The estimates for specific disorders were 0.1% for drug misuse, 3.4% for alcohol misuse, 4.0% for depression, 6.2% for PTSD, 6.4% for anxiety, and 9.3% for insomnia. Postdeployment stressors, OR = 1.91, 95% CI [1.79, 2.04]; employment status, OR = 1.41, 95% CI [1.33, 1.48]; and traumatic exposure during deployment, OR = 1.11, 95% CI [1.09, 1.12], were positively related to PTSD, χ2(17, N = 8,568) = 1,791.299, p < .001. Similar patterns were found for the other MHPs. Considering that most participants (84.9%) reported low symptom levels, our findings challenge the widespread public perception that most peacekeepers have MHPs. Moreover, our results indicate that future peacekeepers should be prepared for challenges they may face not only during deployment but also in the years following their homecoming.

The Wellbeing of Italian Peacekeeper Military: Psychological Resources, Quality of Life and Internalizing Symptoms

Working as a peacekeeper is associated with the exposure to acute and/or catastrophic events and chronic stressors. Hence, the meager literature about peacekeepers' wellbeing has mainly analyzed Post-Traumatic Stress Disorder (PTSD). This study aims to deep the analysis of the wellbeing of peacekeepers military. Based on the few studies on this population, we hypothesized that Italian peacekeeper military officers and enlisted men (n = 167; 103 males, 6 females, 58 missing) exhibit lower levels of internalizing symptoms (i.e., PTSD, depression, general anxiety, obsessions, and somatization) as compared to a control group (n = 60; 32 males, 28 females). Moreover, we hypothesized that peacekeepers have higher levels of psychological resources (i.e., self-efficacy, self-esteem, social support) and quality of life (i.e., higher life satisfaction and lower general stress). We compared the groups by means of MANOVAs on the subscales of the Psychological Treatment Inventory (PTI; Gori et al., 2015). We found that Italian peacekeepers have lower internalizing symptoms and higher levels of self-efficacy and self-esteem than the control group; however, no statistically significant differences were observed on perceived social support. Finally, peacekeepers have a higher quality of life: scores reflect higher life satisfaction and lower distress than the control group. This study is in line with previous literature supporting the claim that Italian peacekeeper military officers have sufficient psychological resources for coping with the stressful situations implied in peacekeeping missions. Future studies should deepen the analysis of the military's psychological characteristics by comparing war veterans and peacekeeper military.

Prevalence and severity of mental disorders in military personnel: a standardised comparison with civilians

AIMS

Provision and need for mental health services among military personnel are a major concern across nations. Two recent comparisons suggest higher rates of mental disorders in US and UK military personnel compared with civilians. However, these findings may not apply to other nations. Previous studies have focused on the overall effects of military service rather than the separate effects of military service and deployment. This study compared German military personnel with and without a history of deployment to sociodemographically matched civilians regarding prevalence and severity of 12-month DSM-IV mental disorders.

METHOD

1439 deployed soldiers (DS), 779 never deployed soldiers (NS) and 1023 civilians were assessed with an adapted version of the Munich Composite International Diagnostic interview across the same timeframe. Data were weighted using propensity score methodology to assure comparability of the three samples.

RESULTS

Compared with adjusted civilians, the prevalence of any 12-month disorder was lower in NS (OR: 0.7, 95% CI: 0.5-0.99) and did not differ in DS. Significant differences between military personnel and civilians regarding prevalence and severity of individual diagnoses were only apparent for alcohol (DS: OR: 0.3, 95% CI: 0.1-0.6; NS: OR: 0.2, 95% CI: 0.1-0.6) and nicotine dependence (DS: OR: 0.5, 95% CI: 0.3-0.6; NS: OR: 0.5, 95% CI: 0.3-0.7) with lower values in both military samples. Elevated rates of panic/agoraphobia (OR: 2.7, 95% CI: 1.4-5.3) and posttraumatic stress disorder (OR: 3.2, 95% CI: 1.3-8.0) were observed in DS with high combat exposure compared with civilians.

CONCLUSIONS

Rates and severity of mental disorders in the German military are comparable with civilians for internalising and lower for substance use disorders. A higher risk of some disorders is reduced to DS with high combat exposure. This finding has implications for mental health service provision and the need for targeted interventions. Differences to previous US and UK studies that suggest an overall higher prevalence in military personnel might result from divergent study methods, deployment characteristics, military structures and occupational factors. Some of these factors might yield valuable targets to improve military mental health.

Occupational stress and UN peacekeepers

BACKGROUND

Ireland has been actively involved in peacekeeping operations since the 1950s. The unique psychological stressors associated with this form of military activity have been under-recognised and under-researched. Aim The aim of this paper is to bring to the attention of mental health professionals, who have been caring for military and retired military peacekeeping personnel, the unique difficulties associated with peacekeeping and how they can impact upon the mental health of the peacekeeper.

METHODS

The nature of peacekeeping is outlined. There is a short review of the limited literature on the mental health effects of this kind of military deployment. There is also an outline of the positive outcomes for the majority of those who have served as peacekeepers.

RESULTS

Both the negative and the positive mental health outcomes depend on the particular mission. Each mission is different and the nature of a mission also changes over time. Post-traumatic stress disorder rates can vary from 3% to 15% of a peacekeeping cohort, depending upon the nature of the violence associated with the mission. The vast majority of peacekeepers have found their peacekeeping deployments as an enriching experience.

CONCLUSION

Peacekeepers are often witnesses as well as the victims of traumatic events. The restrictions placed upon their military role by the mission mandate can be a source of stress for them. Their mental health needs to be supported during the mission and after they have returned home.

Is peacekeeping peaceful? A systematic review

OBJECTIVE

To systematically review the literature on the association between deployment to a peacekeeping mission and distress, mental disorders, and suicide.

METHODS

Peer-reviewed English publications were found through key word searches in MEDLINE, PsycINFO, Scopus, and Embase, and by contacting authors in the field. Sixty-eight articles were included in this review.

RESULTS

Some studies have found higher levels of postdeployment distress and posttraumatic stress disorder (PTSD) symptoms. Most studies have not shown an increased risk of suicide in former peacekeepers. Correlates of distress and PTSD symptoms included level of exposure to traumatic events during deployment, number of deployments, predeployment personality traits or disorder, and postdeployment stressors. Perceived meaningfulness of the mission, postdeployment social supports, and positive perception of homecoming were associated with lower likelihood of distress.

CONCLUSIONS

Most peacekeepers do not develop high levels of distress or symptoms of PTSD. As postdeployment distress is consistently shown to be associated with high levels of exposure to combat during deployment, targeted interventions for peacekeepers who have been exposed to high levels of combat should be considered.
