Posttraumatic stress disorder (PTSD) is associated with altered hypothalamic-pituitary-adrenal (HPA) axis function. Measurement of hair cortisol concentrations (HCC) allows retrospective assessment of HPA axis regulation over prolonged periods of time. Currently, research investigating HCC in PTSD remains sparse. Previous cross-sectional studies have included only civilian populations, although it is known that trauma type moderates associations between PTSD status and HPA axis function.

Objective: Exposure to potentially traumatic events (PTEs) has been identified as a risk factor for various psychological problems in adolescents generally and in young refugees. The aim of this study was to examine whether individual resilience (assessed as a personality characteristic) can protect adolescents in diverse contexts from negative effects of trauma exposure.
Background: Previous research has identified a vulnerability paradox in global mental health: contrary to positive associations at the individual level, lower vulnerability at the country level is accompanied by a higher prevalence in a variety of mental health problems in national populations. However, the validity of the paradox has been challenged, specifically for bias from modest sample sizes and reliance on a survey methodology not designed for crossnational comparisons.
Police officers exposed to potentially traumatic events (PTE) are at a heightened risk of developing posttraumatic stress disorder (PTSD). Little is known about trauma‐focused psychotherapy outcomes in the police. In this naturalistic study, we evaluated whether PTE exposure and baseline clinical characteristics predicted PTSD symptom reduction during treatment and residual PTSD symptoms posttreatment. In consecutive referrals to a specialized mental health service for police officers (N = 665), PTSD was measured pre‐ and posttreatment using structured clinical interviews.
In 2008, Taliban forces killed four aid workers in Afghanistan. Immediately afterwards, expatriate and national field staff undertook crisis management activities on the ground. While this was a devastating event, field and headquarters staff agreed that the organisational response to the crisis was positive. Nine months later, 19 expatriate staff members involved in the crisis response participated in an evaluation to reflect on personal and organisational factors that contributed to their post crisis resilience.
Posttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder that may develop after a traumatic event. Here we aimed to identify epigenetic and genetic loci associated with PTSD. We included 73 traumatized police officers with extreme phenotypes regarding symptom severity despite similar trauma history: n = 34 had PTSD and n = 39 had minimal PTSD symptoms.
Consistent failure over the past few decades to reduce the high prevalence of stress-related disorders has motivated a search for alternative research strategies. Resilience refers to the phenomenon of many people maintaining mental health despite exposure to psychological or physical adversity. Instead of aiming to understand the pathophysiology of stress-related disorders, resilience research focuses on protective mechanisms that shield people against the development of such disorders and tries to exploit its insights to improve treatment and, in particular, disease prevention.
Prehospital providers are at increased risk for psychological distress. Support at work after critical incidents is believed to be important for providers, but current guidelines are in need of more scientific evidence. This study aimed to investigate: (1) to what extent prehospital providers experience support at work; (2) whether support at work is directly associated with lower distress and (3) whether availability of a formal peer support system is related to lower distress via perceived colleague support.
