2001 JUL 12 - (NewsRx Network) -- A research study to investigate a little-used psychotherapy method is being launched in the U.S. and will examine treatment of military women for posttraumatic stress disorder (PTSD).
Believed to be the largest study of its kind, the research takes a multi-site approach to gathering data, and the results will be widely applicable to the general population. Primarily small, community-based studies have been done in the past.
This new study will focus on the treatment method known as prolonged exposure where the therapist leads the patient through a vivid memory of a traumatic event until the patient no longer experiences a strong emotional response. This method currently is not widely used for treating PTSD but has shown promise in clinical trials. The established mainstream therapy, called present-centered therapy, focuses on current problems while avoiding discussion of the traumatic event.
The five-year study, titled "Cognitive-Behavioral Therapy for Treatment of PTSD in Women," began July 1, 2001, and focuses on military women. The principal investigators are Paula Schnurr and Matthew Friedman, Dartmouth Medical School professors of psychiatry, and their colleague Lt.Col. Charles Engel, chief, Deployment Health Clinical Center at the Walter Reed Army Medical Center, Washington, DC.
Approximately 8% to 10% of military women, both active duty and veteran, suffer from PTSD, and are more than twice as likely as the average American man to develop the disorder. Although these women suffer an unusually high rate of PTSD, they tend to be overlooked in the research on PTSD.
"Even at facilities that have special programs for women, it would not be possible to obtain enough women at a single site to attain acceptable statistical power during a reasonable time frame," said Schnurr.
The study will incorporate data from 12 sites across the United States and will include 48 therapists and 384 patients.
