Is there a vulnerability paradox in PTSD? : Pitfalls in cross-national comparisons of epidemiological data

Dückers et al analyse the relationship between prevalence estimates of trauma exposure and post-traumatic stress disorder (PTSD) in published data-sets from 24 countries, and between PTSD and vulnerability (based on a country vulnerability index developed in the 2013 World Risk report). The findings are substantially counterintuitive; countries with low vulnerability have higher life-time rates of PTSD, meaning that countries with low vulnerability and high trauma exposure have the highest rates of lifetime PTSD.

PTSD symptom trajectories in disaster volunteers : The role of self-efficacy, social acknowledgement, and tasks carried out

Millions of volunteers respond after disasters, with a 24% to 46% risk of developing posttraumatic stress disorder (PTSD). It is unclear which symptom trajectories develop and how they differ between core (volunteering before the disaster) and noncore volunteers (joining after the disaster) and which factors predict trajectories. Symptoms of PTSD were assessed at 6-, 12-, and 18-months postearthquake in 449 volunteers in Indonesia.

Trauma occurs in social contexts

Vilnius, Lithuania's capital, was the beautiful location of the 14th Conference of the European Society of Traumatic Stress studies (ESTSS) from June 10 to 13, 2015. The main theme of this two-yearly conference was “Trauma in changing societies: social contexts and clinical practice.” The topic of the conference is timely, unfortunately. The current crisis in Syria changed (and is still changing) societies, especially in the Middle East.

Intranasal oxytocin enhances neural processing of monetary reward and loss in post-traumatic stress disorder and traumatized controls

Abstract
Background
Anhedonia is a significant clinical problem in post-traumatic stress disorder (PTSD). PTSD patients show reduced motivational approach behavior, which may underlie anhedonic symptoms. Oxytocin administration is known to increase reward sensitivity and approach behavior. We therefore investigated whether oxytocin administration affected neural responses during motivational processing in PTSD patients and trauma-exposed controls.

Cognitive behavioural therapy for psychopathology in relatives of missing persons : study protocol for a pilot randomised controlled trial

Abstract
Background: It is hypothesized that the grieving process of relatives of missing persons is complicated by having
to deal with uncertainty about the fate of their loved one. We developed a cognitive behavioural therapy (CBT)
with mindfulness that focuses on dealing with this uncertainty. In this article, we elucidate the rationale of a pilot
randomised controlled trial (RCT) for testing the feasibility and potential effectiveness of this CBT for reducing

Prolonged grief and post-traumatic stress among relatives of missing persons and homicidally bereaved individuals : A comparative study

Abstract
Background

Traumatic loss (e.g., homicide) is associated with elevated prolonged grief disorder (PGD) and posttraumatic stress disorder (PTSD). Several studies comparing relatives of missing persons with homicidally bereaved individuals showed inconsistent results about the difference in PGD- and PTSD-levels between the groups. These studies were conducted in the context of armed conflict, which may confound the results. The current study aims to compare PGD- and PTSD-levels between the groups outside the context of armed conflict.

Predicting post‐traumatic stress disorder treatment response in refugees : Multilevel analysis

Abstract
Objectives
Given the recent peak in refugee numbers and refugees’ high odds of developing post-traumatic stress disorder (PTSD), finding ways to alleviate PTSD in refugees is of vital importance. However, there are major differences in PTSD treatment response between refugees, the determinants of which are largely unknown. This study aimed at improving PTSD treatment for adult refugees by identifying PTSD treatment response predictors.

Intranasal Oxytocin Affects Amygdala Functional Connectivity after Trauma Script-Driven Imagery in Distressed Recently Trauma-Exposed Individuals.

Approximately 10% of trauma-exposed individuals go on to develop post-traumatic stress disorder (PTSD). Neural emotion regulation may be etiologically involved in PTSD development. Oxytocin administration early post-trauma may be a promising avenue for PTSD prevention, as intranasal oxytocin has previously been found to affect emotion regulation networks in healthy individuals and psychiatric patients.

Trauma-related self-defining memories and future goals in Dissociative Identity Disorder.

This study examined the content of self-defining autobiographical memories in different identities in patients with Dissociative Identity Disorder (DID) and comparison groups of patients with PTSD, healthy controls, and DID simulators. Consistent with the DID trauma model, analyses of objective ratings showed that DID patients in trauma identities retrieved more negative and trauma-related self-defining memories than DID patients in avoidant identities.
