- Clinical Trial
- Journal Article
Summary
This research article studies the effects of Equine-Assisted Therapy (EAT-PTSD) for Posttraumatic Stress Disorder (PTSD) among military veterans. The study found EAT-PTSD to be a promising, safe, and feasible treatment method that could potentially improve PTSD symptoms.
Overview
In this study, an 8-session group method of Equine-Assisted Therapy for Posttraumatic Stress Disorder (EAT-PTSD) was tested on military veterans who were seeking treatment for PTSD. The research was conducted between July 2016 to July 2019 amongst 63 veterans, with PTSD diagnoses confirmed through established clinical and assessment tools.
Methods
- The mean age of the participants was 50 years c and 37% of them (23 patients) were women.
- PTSD diagnosis was confirmed using the Structured Clinical Interview for, Research Version (SCID-5-RV) and further reaffirmed using the Clinician-Administered PTSD Scale (CAPS-5).
- The researchers then recorded clinician and self-reported measurements of PTSD and depression before, during, and after the treatment, with a follow-up at 3 months.
Results
- Only 8% of the patients (5 individuals) chose to withdraw from the treatment, indicating high compliance and acceptance rate for this therapy.
- Post-treatment results revealed significant reductions in both clinician-rated and self-reported PTSD and depression symptoms, which was found to have persisted even after 3 months of concluding the therapy. Specifically, the mean CAPS-5 scores dropped from 38.6 to 26.9 after the treatment ended.
- Approximately half of the participants exhibited clinically significant changes, demonstrated as at least 30% decrease in CAPS-5 score at both post-treatment and follow-up stages.
Conclusion
Based on the encouraging preliminary results, the manualized EAT-PTSD therapy was found to be a feasible, safe, and effective treatment option for PTSD among military veterans. The authors of the study recommend conducting larger and more controlled trials to further examine the effectiveness of EAT-PTSD in managing PTSD symptoms among veterans.
