Researchers suggest diagnostic criteria for posttraumatic stress disorder are lacking

17.12.2010
Current diagnostic procedures for posttraumatic stress disorder (PTSD) fail to adequately reflect research into the broad nature of a traumatic event, according to a study that will appear in the January print issue of Psychological Bulletin.

The relevancy of an individual's subjective experience in determining what constitutes a traumatic event has been a source of debate among PTSD specialists for years. The study concludes that both objective and subjective factors are relevant and that current PTSD criteria are missing several reactions that many trauma survivors experience.

The study's authors conducted a comprehensive literature review of the research on peritraumatic experiences and the types of reactions that trauma survivors often demonstrate. They found that individuals adapt to extreme experiences in a highly complex and coordinated manner.

"A person's response is multifaceted and may include appraisals and other thoughts, a variety of felt emotions and behaviors. It's not enough to rely on the objective qualities of an experience to determine whether it should be considered traumatic or not," said co-author Brian P. Marx, PhD, an associate professor of psychiatry at Boston University School of Medicine and psychologist at the VA National Center for PTSD. "Trauma should be defined as the interaction between the individual and his or her environment and all parts of an individual's response should be considered."

PTSD is believed to be the result of exposure to trauma, so understanding what defines a traumatic experience is critical. Current criteria for PTSD in the Diagnostic and Statistical Manual include few distinct subjective emotions. The authors suggest that researchers investigate and add more appropriate examples to these criteria in order to more accurately categorize traumatic events.

"Knowing exactly what trauma is can help us to better know who is a trauma survivor and who is not," said Marx. "It is critical that we know this for the purposes of understanding the disorder as well as being better able to help those who are survivors of trauma."

These findings currently appear in Psychological Bulletin online.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
