The Relationship between Lifetime Exposure to Potentially Traumatic Events, Peritraumatic Dissociation, and PTSD in a Sample of Sexually Assaulted Women in Sao Paulo, Brazil

Sexually assaulted women represent a particularly high-risk group for developing post-traumatic stress disorder (PTSD). Potentially traumatic events (PTEs) and peritraumatic dissociation (PD) are known risk factors for PTSD. However, little is known about how previous trauma affects PD and how this relationship affects PTSD. We aimed to investigate whether PD acts as a mediator between PTEs and PTSD severity in a sample of recently sexually assaulted women in Sao Paulo, Brazil.

Effects of prenatal exposure to the 1944–45 Dutch famine and glucocorticoid receptor polymorphisms on later life PTSD susceptibility

Background: Exposure to adversity in utero is thought to increase susceptibility to develop posttraumatic stress disorder (PTSD) following later life trauma, due to neurobiological programming effects during critical developmental periods. It remains unknown whether effects of prenatal adversity on PTSD susceptibility are modulated by genetic variations in neurobiological pathways implicated in PTSD susceptibility.

Traumatic Grief : The Intersection of Trauma and Grief

This chapter focuses on the mental vulnerability of traumatic grief and recovery with this vulnerability, which implies a reduction in the number or intensity of symptoms or distress. Grief is characterized by an ambiguous presence-in-absence of the deceased, involving existential concerns such as isolation and meaninglessness.

A comparison of the CAPS-5 and PCL-5 to assess PTSD in military and veteran treatment-seeking samples

Background: This study was an examination of the puzzling finding that people assessed for symptoms of posttraumatic stress disorder (PTSD) consistently score higher on the self-report PTSD Checklist for DSM-5 (PCL-5) than the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5). Both scales purportedly assess PTSD severity with the same number of items, scaling, and scoring range, but differences in scores between measures make outcomes difficult to decipher.

Sex‑Based Contributors to and Consequences of Post‑traumatic Stress Disorder

Purpose of Review

Women are twice as likely to develop post-traumatic stress disorder (PTSD) compared to men after a traumatic experience. The purpose of this mini review was to explore recent research on biological contributors to this sex difference.

Sleep impairments in refugees diagnosed with post-traumatic stress disorder : a polysomnographic and self-report study

Background: Post-traumatic stress disorder (PTSD) is the clinical manifestation of traumatic events and is associated with sleep disturbances. Sleep disturbances, if left untreated, may perpetuate or even worsen symptoms of PTSD. Previous studies of other PTSD populations show a higher incidence of sleep impairments and sleep disorders compared to healthy controls (HCs); however, this has never been investigated in trauma-affected refugees diagnosed with PTSD.

The associations between metabolic profiles and sexual and physical abuse in depressed adolescent psychiatric outpatients : an exploratory pilot study

Background: Sexual and physical abuse have been associated with long-term systemic alterations such as low-grade inflammation and changes in brain morphology that may be reflected in the metabolome. However, data on the metabolic consequences of sexual and physical abuse remain scarce.

 

Objective: This pilot study sought to investigate changes in the metabolite profile related to sexual and physical abuse in depressed adolescent psychiatric outpatients.

Exploring the associations between social support and symptoms of posttraumatic stress disorder among Malaysian and Australian trauma survivors

Background: Social support is an important feature in understanding posttraumatic stress disorder (PTSD) and its treatment. Non-clinical research has identified distinct profiles of culturally appropriate social support. Despite this, little research has examined cultural influences on social support in the context of PTSD.

 

Objective: This study examined cultural differences in the associations between social support and symptoms of PTSD.

Moral injury associated with increased odds of past-year mental health disorders : a Canadian Armed Forces examination

Background: Potentially morally injurious experiences (PMIEs) are common during military service. However, it is unclear to what extent PMIEs are related to well-established adverse mental health outcomes.

 

Objective: The objective of this study was to use a population-based survey to determine the associations between moral injury endorsement and the presence of past-year mental health disorders in Canadian Armed Forces (CAF) personnel and Veterans.
