Subclinical presentations of posttraumatic stress disorder (PTSD), wherein patients are one or two symptom criteria short of the full disorder, are prevalent and associated with levels of distress and impaired functioning approximating that of full PTSD. Nonetheless, research examining treatment efficacy for this group is in the nascent stage. The purpose of the present study was to examine whe...

BACKGROUND Post-traumatic stress disorder (PTSD) is a chronic and difficult to treat psychiatric disorder. Objective, performance-based diagnostic markers that uniquely index risk for PTSD above and beyond subjective self-report markers could inform attempts to improve prevention and early intervention. We evaluated the predictive value of threat-related attention bias measured immediately afte...

The DSM-5 currently includes a dissociative-PTSD subtype within its nomenclature. Several studies have confirmed the dissociative-PTSD subtype in both American Veteran and American civilian samples. Studies have begun to assess specific factors which differentiate between dissociative vs. non-dissociative PTSD. The current study takes a novel approach to investigating the presence of a dissocia...

It remains unclear whether white matter (WM) changes found in post-traumatic stress disorder (PTSD) patients are stress-induced or precursors for vulnerability. The current study aimed to identify susceptibility factors relating to the development of PTSD and to examine the ability of these factors to predict the course of longitudinal PTSD. Sixty two victims who had experienced traffic acciden...

We examined hopelessness and suicidal ideation in association with subthreshold and threshold posttraumatic stress disorder (PTSD) in a sample of Iraq and Afghanistan War Veterans (U.S., N 275) assessed within a specialty VA postdeployment health clinic. Veterans completed paper-and-pencil questionnaires at intake. The military version of the PTSD Checklist was used to determine PTSD levels (No...

The process that resulted in the diagnostic criteria for posttraumatic stress disorder (PTSD) in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association; ) was empirically based and rigorous. There was a high threshold for any changes in any DSM-IV diagnostic criterion. The process is described in this article. The rationale is presented that ...

Children and adolescents are more susceptible than adults to developing posttraumatic stress disorder (PTSD). Pediatric PTSD is characterized by functional alterations in brain fear circuitry, but little known about the underlying microstructural changes; previous work has mainly focused on corpus callosum. This study aimed at investigating brain-wide abnormalities pediatric PTSD, their relatio...

The correlation between the kind of cesarean section and post-traumatic stress disorder (PTSD) in Greek women after a traumatic birth experience has been recognized previous studies along with other risk factors, such as perinatal conditions life events. Data from early have suggested some possible links vulnerable factors potential development postpartum PTSD. classification each case three st...

A variety of structural abnormalities have been described in post traumatic stress disorder (PTSD), but only a few studies have focused on cortical thickness alterations in recent onset PTSD. In this study, we adopted surface-based morphometry (SBM), which enables an exploration of global structural changes throughout the brain, in order to compare cortical thickness alterations in recent onset...
