The present study investigated symptom relations between two highly comorbid disorders--posttraumatic stress disorder (PTSD) and generalized anxiety disorder (GAD)--by exploring their underlying dimensions. Based on theory and prior empirical research it was expected that the dysphoria factor of PTSD would be more highly related to GAD. As part of a longitudinal project of mental health among O...

Post traumatic stress disorder (PTSD) occurs across 15-20% of victims suffering physical injury. The occurrence of PTSD has been attributed to both the trauma and the victim's individual resources, such as resilience, coping strategies, and social support systems. In the present study, we explored the role of self-efficacy for cognitive self-regulation in the posttraumatic adaptation process of...

posttraumatic stress disorder (ptsd) occurs following exposure to potentially traumatic experiences such as those regularly encountered by emergency service workers (police, ambulance and firemen/women) and servicemen/women. ptsd is associated with high rates of somatic comorbidities including metabolic syndrome contributing to an excess mortality rate due to preventable cardiovascular diseases...

BACKGROUND Although sustaining physical injury in theater increases service members' risk for posttraumatic stress disorder (PTSD), exposure to explosive munitions may increase the risk of mild traumatic brain injury (mTBI). We hypothesized a higher incidence of PTSD and mTBI in service members who sustained both burn and explosion injuries than in nonexplosion exposed service members. METHOD...

Since posttraumatic stress disorder (PTSD) was first recognized as a psychiatric disorder, it has generated a great deal of scientific interest. Recent studies on the neurobiology of PTSD provide evidence that PTSD is biologically distinct from other types of traumatic and nontraumatic stress responses. This paper reviews three important directions of neurobiological research in PTSD: noradrene...

OBJECTIVES The objectives of this study were to investigate the prevalence of posttraumatic stress disorder in patients with a first myocardial infarction compared with a random sample of healthy controls and to determine variables associated with the disorder. DESIGN A questionnaire was distributed to 112 consecutive patients 4 to 6 weeks after infarction and to 115 healthy controls selected...

A prospective longitudinal follow-up study (n = 59) of child and adolescent survivors of physical assaults and motor vehicle accidents assessed whether cognitive processes predicted posttraumatic stress symptomatology (PTSS) at 6 months posttrauma in this age group. In particular, the study assessed whether maladaptive posttraumatic appraisals mediated the relationship between initial and later...

The wars in Iraq and Afghanistan have produced historically low rates of fatalities, injuries, and posttraumatic stress disorder (PTSD) among U.S. combatants. Yet they have also produced historically unprecedented rates of PTSD disability compensation seeking from the U.S. Department of Veterans Affairs. The purpose of this article is to consider hypotheses that might potentially resolve this p...

This study compared the cognitions of 37 female rape survivors before and after completing cognitive processing therapy (CPT). It was hypothesized that CPT would be associated with reductions in posttraumatic stress disorder (PTSD) symptoms and problematic (i.e., assimilated and overaccommodated) thoughts as well as increases in the number of realistic (i.e., accommodated) cognitions. Cognition...

C in patterns of attention allocation following traumatic exposure have been implicated in the development and maintenance of posttraumatic stress symptoms (1-4). Attentional allocation is defined, in part, by absorption and dissociation, constructs which require further empirical investigation vis-à-vis posttraumatic stress (5). Dissociation is characterized as a process involving “disruption ...
