Background: Internationally deployed humanitarian aid (HA) workers are at risk for traumatic and chronic stress, and consequently stress-related psychopathology. Therefore, HA deployment may lead to long-term changes in neuroendocrine stress reactivity. Objective: We investigated whether awakening cortisol changed upon deployment, and whether this was associated with lifetime childhood and adulthood traumatic stressors, current deployment-related traumatic and chronic stressors and within-person changes in stress-related symptomatology upon deployment. Method: From a prospective study among expatriate HA workers (n = 214) from 19 international NGOs, we included n = 86 participants (68% females, 33 ± 8 years) who completed questionnaires and cortisol assessments at three points: pre-deployment, early post-deployment and 3–6 months post-deployment. At each assessment, cortisol parameters were calculated from two saliva samples: at awakening and 30 minutes post-awakening. Results: Linear mixed models showed significant decreased awakening cortisol over time (bs: −.036 [SE = .011] to −.008 [SE = .003], all ps < .007). Cortisol was significantly predicted by three-way interactions between lifetime stressors, deployment stressors and time, with the smallest decrease over time in those with limited lifetime and current stressors (all ps < .05). The change in cortisol was no longer significant upon inclusion of stress-related symptoms in the model. Moreover, a sharper cortisol decrease was significantly associated with higher anxiety (p = .004) and PTSD symptoms (p = .049) across assessments. Conclusions: This is the first study indicating decreased awakening cortisol after HA deployment. The exact decrease within participants depended on the amount of lifetime and current stressors. Importantly, when taking changes in stress-related symptomatology into account, we found these accounted for the attenuated awakening cortisol.
Factors associated with common mental health problems of humanitarian workers in South Sudan
(PLoS, 2018-10-31) Strohmeier, Hannah; Scholte, Willem F.; Ager, Alastair
Background - The latest data on major attacks against civilian aid operations have identified South Sudan as the most dangerous country for aid workers globally. Exposure to other traumatic events and chronic stress is also common in this population. No research exists on the mental health of humanitarian workers in South Sudan. Objectives - This study examined symptom burden and predictors of posttraumatic stress disorder (PTSD), depression, anxiety, hazardous alcohol consumption, and burnout among humanitarian workers in South Sudan. Method - We conducted a cross-sectional online survey with humanitarian workers (national and international staff, consultants, United Nations volunteers). We applied validated measures useful for this setting. We applied Least Absolute Shrinkage and Selection Operator (LASSO) regression to fit models with high prediction accuracy for each outcome and used ordinary least squares (OLS) regression to obtain final coefficients and perform inference. Results - A total of 277 humanitarian workers employed by 45 organizations completed the survey (a response rate in the order of 10%). We estimated prevalence of PTSD (24%), depression (39%), anxiety disorder (38%), hazardous alcohol consumption in men (35%) and women (36%), and the burnout components emotional exhaustion (24%) and depersonalization (19%). Chronic stress exposure was positively associated with PTSD (p < .001), depression (p < .001), anxiety (p < .001), emotional exhaustion (p < .01), and depersonalization (p < .001). We found no significant association between emotion focused and problem focused coping and mental health outcomes. Associations between dysfunctional coping and depression (p < .001) and anxiety (p < .01) were positive. Higher levels of spirituality were associated with lower risk of hazardous alcohol consumption (p < .001). Contrary to expectations, working directly with humanitarian aid beneficiaries was significantly associated with lower risk for emotional exhaustion (p < .01). Conclusion - Our results suggest that humanitarian workers in South Sudan experience substantial levels of mental ill-health. This study points to the need for staff support strategies that effectively mitigate humanitarian workers’ chronic stress exposure. The dynamics between coping and mental health among humanitarian workers require further study.
How to improve organisational staff support? Suggestions from humanitarian workers in South Sudan
(Wolters Kluwer - Medknow, 2019-06-28) Strohmeier, Hannah; Scholte, Willem F.; Ager, Alastair
Humanitarian workers experience high symptom burdens of common mental health problems. This requires action from the organisations they are employed with. However, many studies have documented continuing weaknesses in organisational staff support, as well as disparities in access to the services for national and international staff. Systematic data capturing suggestions from humanitarian workers on how to tackle this situation within a specific crisis setting is rarely available. This study addresses this gap through qualitative content analysis of the suggestions from the 210 humanitarian workers based in South Sudan collected through an online survey in 2017. Five major themes emerged regarding proposed improvements: ‘Competitive benefit and salary packages’; ‘internal work climate and organisational culture’; ‘equality within and between organisations’; ‘skill enhancement and personal development’ and ‘physical safety and security’. For both national and international staff, improved access to psychosocial support services was the most frequent proposal. Apart from this suggestion, their top priorities for improvement of staff support differed greatly. National staff emphasised improvements related to training and greater equality between employees. International staff emphasised improvements related to time off and team cohesion. Findings provide a clear case for organisations to assess their services and offer a potential framework to inform future interventions that better address the priorities of the humanitarian community as a whole.
