Objective: The development of posttraumatic stress disorder (PTSD) is influenced by preexisting vulnerability factors. The authors aimed at identifying a preexisting biomarker representing a vulnerability factor for the development of PTSD. To that end, they determined whether the dexamethasone binding capacity of leukocytes, as a measure of glucocorticoidreceptor (GR) number, before exposure to trauma was a predictor of development of PTSD symptoms.

In this study, we investigated the prevalence, severity, and organisational factors of risk for psychological injury in a national sample of Australian school teachers, using the Psychological Injury Risk Indicator. We predicted that teachers would report higher levels of risk for psychological injury if working in schools located in rural areas, with a low socioeconomic index, and low psychosocial safety climate. Teachers from across Australia (N = 960) completed an online survey that measured risk for psychological injury and relevant organisational factors.

Previous research has consistently demonstrated that Prolonged Exposure (PE) therapy is an effective treatment for posttraumatic stress disorder (PTSD). Traditionally, PE has been studied and delivered on an individual basis. However, the growing number of Veterans in need of PTSD treatment has led to increased interest in group therapies as an efficient way to provide access to care. The current study examined a group and individual hybrid treatment that was developed based on PE principles.

The diagnostic criteria for posttraumatic stress disorder (PTSD) were substantially revised for Diagnostic and Statistical Manual of Mental DisordersGÇö5th edition (DSM-5). This in turn necessitated revision of DSM-correspondent assessment measures of PTSD. We describe the various changes to the PTSD diagnostic criteria and the corresponding changes to National Center for PTSD measures. We also discuss the implications of the new criteria for assessment of trauma exposure and PTSD.
