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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
