Veterans who have killed in combat and suffer from nightmares, hyper-vigilance to perceived threats, and numbness to people and activities that once made them happy, may be helped by a six-to-eight week talk therapy program, a UC San Francisco study has found.
In the study, 33 veterans with post-traumatic stress disorder (PTSD) were enrolled in six-to-eight one-on-one sessions with a licensed psychologist. The veterans had either “endorsed killing” or were “responsible for the death of another in a war zone,” said first author Shira Maguen, PhD, associate professor in the UCSF Department of Psychiatry and mental health director of the San Francisco VA Health Care System Integrated Care Clinic.
The study follows earlier work by Maguen that found veterans with killing experiences were twice as likely to think about suicide as those who had not killed.
In the current study, published Aug. 17, 2017, in the Journal of Clinical Psychology, Maguen and her co-investigators assessed the mental health of 17 veterans who had completed the program, and compared the results with 16 counterparts who were waitlisted for the same treatment. While both groups of veterans suffered from PTSD and had killed in combat, the group that had completed the program experienced a 63 percent drop in depression symptoms, 43 percent improvement in anxiety and a 37 percent dip in general psychiatric symptoms.
Difficulties with closeness, intimacy
The participants were all male, with an average age of 61, and 14 of the 17 had served in Vietnam.
“Many of the veterans struggled with difficulties getting close to people, intimacy with partners and a belief that they were no longer lovable,” said Maguen. “Others were unable to trust their anger after killing, or felt that they deserved to suffer.”
Components of the program included identifying the barriers to feeling better, such as numbing feelings with drugs or alcohol, living in an unhealthy environment or sabotaging personal relationships. Participants worked with psychologists to challenge “killing cognitions,” those beliefs that the deaths had made them unworthy of affection, trust or respect.
A latter phase of the program involved self-forgiveness – “a key ingredient in healing,” according to Maguen.
Practicing compassion for self and others
“Self-forgiveness might involve volunteering, reconnecting with friends and family who were cut off, tutoring children, or even going back to the country where the killing occurred and trying to make amends there,” she said.
Finally, participants were encouraged to express “guilt and remorse for those harmed, and sadness and compassion for self and others,” the authors noted in the study.
Currently veterans can receive PTSD evaluation and treatment without ever being asked about killing and its impact, said senior author Thomas Neylan, MD, professor in the UCSF Department of Psychiatry and director of the PTSD clinic at the San Francisco VA Medical Center.
“Veterans have disclosed that although they have spoken in depth about other traumas, they felt that killing should be kept secret,” said Neylan, who is also affiliated with the U.S. Department of Veterans Affairs. “It should be recognized that killing happens in war and is an expected and important part of the veteran’s experience. Creating a culture in which killing is asked about allows for non-stigmatizing discussions about how veterans may be impacted by their killing experiences.”
PTSD is characterized by reliving a terrifying event, avoiding situations that prompt memories of that event, a surge in negative feelings and beliefs, and being hyper-aware of potential dangers. The U.S. Department of Veterans Affairs says that an estimated 30 percent of Vietnam veterans have had PTSD in their lifetime, versus 12 percent of those serving in the Gulf War, and between 11 and 20 percent of those in Iraq and Afghanistan.
