BACKGROUND Psychiatric symptoms typically cut across traditional diagnostic categories. In order to devise individually tailored treatments, there is a need to identify the basic mechanisms that underlie these symptoms. Behavioral economics provides a framework for studying these mechanisms at the behavioral level. Here, we utilized this framework to(More)
We investigated the extent of cortical thinning in U.S. Veterans exposed to combat who varied in the severity of their posttraumatic stress disorder (PTSD) symptoms. In addition, we explored the neural correlates of PTSD symptom dimensions and the interactive effects of combat exposure and PTSD upon cortical thickness. Sixty-nine combat exposed Veterans(More)
OBJECTIVES Numerous studies have shown that individuals with posttraumatic stress disorder (PTSD) display reduced performances on neuropsychological tests, although most prior research has not adequately accounted for comorbidities or performance validity concerns that are common in this population and could partially account for the observed neurocognitive(More)
This study explored the journey of American armed forces personnel from their decision to join the service, through their service in an active military conflict and how these factors may be associated with potential resistance for mental healthcare. The data came from qualitative interviews with 46 OIF/OEF/OND active-duty military, reservists, and(More)
Veterans of Operations Iraqi Freedom/Enduring Freedom/New Dawn (OEF/OIF/OND) tend not to engage in mental health care. Identifying modifiable factors related to mental health service utilization could facilitate development of interventions to increase utilization. The current study examined the relationship between mental health care utilization and(More)
Many patients with post-traumatic stress disorder (PTSD), especially war veterans, do not respond to available treatments. Here, we describe a novel neurofeedback (NF) intervention using real-time functional magnetic resonance imaging for treating and studying PTSD. The intervention involves training participants to control amygdala activity after exposure(More)
Theories of posttraumatic stress disorder (PTSD) implicate emotional processes, including difficulties utilizing adaptive emotion regulation strategies, as critical to the etiology and maintenance of PTSD. Operation Iraqi Freedom, Operation Enduring Freedom, and Operation New Dawn (OIF/OEF/OND) veterans report high levels of combat exposure and PTSD. We(More)
