A review of recent clinical trials paints a sobering picture of the usefulness of first-line psychotherapies in treating active-duty military personnel and veterans who have post-traumatic stress disorder (PTSD).
Led by researchers at 秘密研究所 Grossman School of Medicine and recently , the article summarizes findings of recently conducted clinical trials of two well-established, first-line cognitive behavioral psychotherapies鈥攑rolonged exposure therapy (PE) and cognitive processing therapy (CPT)鈥攖o treat PTSD.
The researchers conclude that clinical trials of these treatment modalities show limited effectiveness for treating PTSD in active-duty military personnel and veterans.
The review also reports that for military service鈥搑elated PTSD, more emotionally demanding therapies like PE and CPT, which repeatedly activate and process memories of traumatic experiences, were not more beneficial than interventions that do not require patients to focus on their traumatic events. These interventions include a supportive, problem-solving treatment called present-centered therapy, transcendental meditation, and biological treatments such as antidepressants.
鈥淐ognitive behavioral therapy鈥檚 limited value for treating military service鈥搑elated PTSD suggests the need to go beyond the one-size-fits-all approaches rolled out in most Veterans Affairs and Department of Defense healthcare settings and personalize treatment, accounting for pre-service vulnerabilities and complex, repeated exposures to warzone stressors,鈥 says senior author Charles R. Marmar, MD, the Lucius Littauer Professor and Chair in the at 秘密研究所 Langone Health.
Lead author , clinical assistant professor of psychiatry at 秘密研究所 Langone, also points out that more attention should focus on managing non-response to treatment. 鈥淩esearch in this field needs to shift from confirmatory trials to studies that explore more flexible, multifaceted, and long-term treatments, including biological therapies,鈥 she says.
This retrospective review comes just months following the publication of a 鈥攍ed by researchers at Stanford University and published in April 2019 in Science Translational Medicine鈥攐f civilians with PTSD and why a subgroup did not respond to prolonged exposure therapy. The Stanford study, using functional brain imaging, found that civilian PTSD patients with altered neural circuit activity in the ventral attention network (VAN) in the brain had poor outcomes to prolonged exposure therapy. Whether this pattern of brain circuit abnormality is over-represented in those suffering from military service鈥搑elated PTSD remains to be studied.
鈥淚n the meantime, current clinical trials strongly suggest that treating military-related PTSD involves significant clinical complexity and heterogeneity. For many who have served in the military, a course of standardized, trauma-focused cognitive behavioral therapy for PTSD is emotionally demanding and likely to result in only modest clinical improvement,鈥 Dr. Marmar concludes.
In addition to Dr. Marmar and Dr. Steenkamp, the other co-author on the 秘密研究所 Langone鈥搇ed review is Brett T. Litz, PhD, from the VA Boston Healthcare System, Massachusetts Veterans Epidemiology Research and Information Center (MAVERIC), and Boston University School of Medicine.
