Implementation of evidence-based treatments (EBT) is necessary to address posttraumatic stress disorder (PTSD) in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) military service personnel. Because virtual reality (VR) offers a promising tool for delivery of one type of EBT--exposure therapy--this study explored veterans' perceptions of VR as(More)
Repetitive transcranial magnetic stimulation (rTMS) holds promise as a probe into the pathophysiology and possible treatment of neuropsychiatric disorders. To explore its regional effects, we combined rTMS with positron emission tomography (PET). Fourteen healthy volunteers participated in a baseline 18-fluorodeoxyglucose (FDG) PET scan. During a second FDG(More)
The current study investigated in a sample of Operation Enduring and Iraqi Freedom (OEF/OIF) veterans how a symptom overreporting response style might influence the association between PTSD diagnostic status and color-naming response latency for trauma-related stimuli during the Modified Stroop Task (i.e., the Modified Stroop Task effect, MST effect). It(More)
Using the event-related potential P3a component as a marker, the authors tested the efficacy of repetitive transcranial magnetic stimulation (rTMS) for reducing hyperarousability to specific threat stimuli in one Vietnam veteran with chronic posttraumatic stress disorder (PTSD), who exhibited an exaggerated P3a response to combat-related pictures. Twenty(More)
Biased appraisal is central to cognitive theories of posttraumatic stress, but little research has examined the potentially distinct meanings of the term. The ongoing process of appraising social information and the beliefs that emerge as products of that process can be distinguished conceptually. This study sought to examine whether these 2 meanings are(More)
