The findings have important implications as combat-related PTSD in military service personnel remains a national public health concern with an estimated 2 to 17 percent of veterans suffering from the disorder.
Veterans who participated in the therapeutic riding program showed clinically significant improvements in depression and post-traumatic stress symptoms compared to those who did not participate.
“PTSD is difficult to treat. But those who went through the program reported lessening of symptoms and better mental health,” said lead author Beth A. Lanning, Ph.D., associate chair and associate professor of public health in Robbins College of Health and Human Sciences at Baylor University in Texas.
“The veterans felt less anxious, depressed, angry and isolated than before the intervention,” she said. “They indicated feelings of self-acceptance, increased confidence, gratitude and hope, as well as increased patience.”
Mental health diagnoses among active duty military personnel have increased by 65 percent during the past decade, including adjustment disorders, depression, substance abuse, anxiety and PTSD, according to the Armed Forces Health Surveillance Center. In addition, the U.S. Department of Veterans Affairs estimates that 20 veterans commit suicide every day.
While animal-assisted activities and therapies are gaining in popularity as an effective intervention for mental and physical health issues among various groups of people, few studies have involved military service members.
The new study is the largest published study designed to look at the immediate and long-term effects of therapeutic riding on post-traumatic stress symptoms, depression and quality of life for military service members, Lanning said.
Requirements for study participants included having served in any of the three Iraq and Afghanistan war missions; not having participated in any equine-assisted therapies or activities in the past six months; and having been diagnosed with PTSD.
The research involved 89 participants divided into two groups — one composed of 51 individuals who went through the horseback riding and one a comparison group of 38 veterans. Those in both groups were allowed to continue traditional therapy such as cognitive behavioral therapy and medications if already enrolled. A little more than half were attending a traditional psychotherapy program; 36 percent had completed a therapy program such as cognitive behavioral therapy.
The 8-week horseback riding program consisted of 90-minute sessions each week, with participants sharing a meal before each session. The first four weeks included grooming, leading and working with the horse in a round pen to develop a relationship. The last four weeks including riding and horsemanship exercises. Participants selected their own horse for the program, and a riding instructor certified by Professional Association for Therapeutic Horsemanship International (PATH) supervised all program sessions. In addition, each horse-rider pair was accompanied by a trained volunteer who was a military service member not participating in the study.
Participants completed self-assessments four different times: Before the start of the study, at the mid-point, at the end of the treatment and at a two-month follow-up. Participants also identified a person who knew them well, such as a significant other or family member, to complete an assessment of participants’ functioning at the beginning and end of the program.
Varying intervention and treatment options are available within and outside the Veterans Affairs healthcare system, but many veterans do not access help or do not complete the course of treatment for a variety of reasons.
A previous study of PTSD treatments found that a little more than half of the individuals who enrolled in and completed traditional therapy no longer met the criteria for PTSD. While encouraging, the failure rate is still high, and many veterans do not seek traditional therapy for mental issues, Lanning said.
Alternative and complementary interventions should be considered as possible treatments to improve mental and physical health. Animal-assisted activities and therapies, specifically with horses, are viable and potentially effective intervention options for various populations, she said.
The study was published in the Human-Animal Interaction Bulletin.
