Relation between aggression exposure in adolescence and adult posttraumatic stress symptoms: Moderating role of the parasympathetic nervous system.

The present study examines the impact of the parasympathetic nervous system (PNS), as measured by respiratory sinus arrhythmia (RSA), on the link between family aggression experienced during adolescence and posttraumatic stress symptoms during young adulthood. Participants completed retrospective self-report measures of interparental aggression and harsh parenting exposure during adolescence and measures of current posttraumatic stress symptoms. RSA indexed PNS activity.

Structure of posttraumatic stress disorder symptoms and psychosocial functioning in Veterans of Operations Enduring Freedom and Iraqi Freedom.

Posttraumatic stress disorder (PTSD) is one of the most prevalent psychiatric conditions in Veterans of Operations Enduring Freedom and Iraqi Freedom (OEF-OIF), but little is known about the structure of PTSD symptoms, and associations between PTSD symptom clusters and psychosocial functioning in this population. A total of 272 OEF-OIF Veterans in Connecticut completed a mail survey containing measures of psychopathology, resilience, and psychosocial functioning. Confirmatory factor analyses revealed that the 4-factor dysphoria model, which is comprised of separate re-experiencing, avoidance, dysphoria, and hyperarousal symptom clusters, provided the best representation of PTSD symptom structure in this sample.

Posttraumatic growth in Veterans of Operations Enduring Freedom and Iraqi Freedom.

Objective: A growing body of research has examined the prevalence and correlates of psychopathology, mild traumatic brain injury, and related problems in Veterans of Operations Enduring Freedom and Iraqi Freedom (OEF-OIF). While these studies help characterize the deleterious effects of combat, no known study has examined factors that may enhance posttraumatic growth or positive changes experienced as a result of combat in this population.

Method: A total of 272 predominantly older Reservist/National Guard OEF-OIF Veterans completed an anonymous mail survey that assessed combat exposure, psychopathology, psychosocial functioning, social support, and posttraumatic growth.

Psychosocial buffers of traumatic stress, depressive symptoms, and psychosocial difficulties in veterans of Operations Enduring Freedom and Iraqi Freedom: the role of resilience, unit support, and postdeployment social support.

Background: Little research has examined the role of protective factors such as psychological resilience, unit support, and postdeployment social support in buffering against PTSD and depressive symptoms, and psychosocial difficulties in veterans of Operations Enduring Freedom (OEF) and Iraqi Freedom (OIF).

Materials And Methods: A total of 272 OEF/OIF veterans completed a survey containing PTSD and depression screening measures, and questionnaires assessing resilience, social support, and psychosocial functioning.

Results: Lower unit support and postdeployment social support were associated with increased PTSD and depressive symptoms, and decreased resilience and psychosocial functioning.
