There is currently a crisis in military veteran mental health care. At 5-30% of veterans receive a PTSD diagnosis. Veterans face a large gap that exists in accessing and receiving high quality care. One intervention that is becoming more popular is equine assisted counseling (EAC). The purpose of the present study was to examine the effectiveness of Relational Equine-Partnered Counseling (REPC) in reducing symptoms of PTSD in military veterans. I also examined specific PTSD symptom clusters including intrusion, avoidance, negative alterations in cognitions and mood, and alterations in arousal and reactivity. The present study utilized a single-case design consisting of a baseline phase, intervention phase, and post-intervention phase. Participants included four military veterans presenting for war zone-related PTSD: four males and one female, aged 32-67 years, two White/European non-Hispanic, one African American non-Hispanic, and one mixed ethnicity. Symptoms were assessed weekly using the Clinician-Administered PTSD Scale and the PTSD Checklist (PCL-5). The data were analyzed by visual analysis and statistical effect size. The results were mixed across the participants. All participants experienced decreased means between the baseline and intervention phases. However, interpretation of the results indicated that the intervention was effective in some areas for some of the participants. All participants reported that the intervention was beneficial in targeting specific symptoms. Overall, the results indicated that REPC may have some benefit in reducing distress related to PTSD. More research is needed to further explore the effectiveness of REPC on the reduction of PTSD-related distress.
