Mark W. Miller, PhD, associate professor at BUSM and a clinical research psychologist at the National Center for PTSD at VA Boston Healthcare System served as lead author of the study, which is published online in Psychological Trauma: Theory, Research, Practice and Policy.
The Diagnostic and Statistical Manual of Mental Disorders (DSM), the handbook that defines psychiatric disorders, has been undergoing revisions for the past decade in advance of the publication of its fifth edition (DSM-5). Included in the proposed revisions are the first major changes to the PTSD diagnosis since its initial appearance in DSM-III back in 1980. These include the addition of new symptoms, revision of existing ones and a new set of diagnostic criteria.
According to DSM-IV, the criteria for a diagnosis of PTSD include exposure to a traumatic event, persistent re-experiencing of the traumatic event, avoidance and emotional numbing, and persistent hyperarousal and hypervigilance. The proposed revisions for DSM-5 involve clarification regarding what constitutes a traumatic event, the addition symptoms such as self-destructive behavior and distorted blaming of oneself or others for the traumatic event and a reorganization of the diagnostic decision rules for establishing a diagnosis of PTSD.
Critics have raised concerns about the revision process, noting that some of the new symptoms are not unique to PTSD. They believe that the proposed changes could lead to a number of misdiagnoses, which could artificially increase the number of patients with the disorder.
To address this and to collect data to inform final decisions about the PTSD revision, research was initiated by the DSM-5 PTSD workgroup to see if these changes would affect the number of people diagnosed with PTSD. The researchers surveyed a nationally representative sample of 2,953 American adults and a second sample of 345 U.S. military veterans. They found that most of the proposed symptom changes were supported by statistical analysis and did not substantially affect the number of people who would meet criteria for the disorder. Based in part on these findings, the workgroup responsible for the PTSD revisions are now moving forward with the proposed revisions for DSM-5.
This research was funded primarily by the U.S. Department of Veterans Affairs Mental Health Service and the American Psychiatric Association DSM Research Program. The study was done in collaboration with Medical University of South Carolina, National Center for PTSD at White River Junction VA Medical Center, Dartmouth Medical School and New England Research Institutes. Other BUSM research collaborators include: Erika J. Wolf, PhD, assistant professor of psychiatry at BUSM and researcher at the National Center for PTSD at VA Boston Healthcare System; Terence Keane, PhD, professor and vice chairman of psychiatry at BUSM and director of the Behavioral Science Division of the National Center for PTSD and associate chief of staff for Research and Development at VA Boston Healthcare System; Brian P. Marx, PhD, professor of psychiatry at BUSM and researcher at the National Center for PTSD at VA Boston Healthcare System; and Darren W. Holowka, PhD, research assistant professor in psychiatry at BUSM and researcher at the National Center for PTSD at VA Boston Healthcare System.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
