About this study

This study seeks to examine feasibility, acceptability, safety, and preliminary efficacy of Equine-Assisted Therapy for veterans with posttraumatic stress disorder (EAT-PTSD). While several well-studied, validated treatments for PTSD exist, some individuals find these treatments ill-suited, ineffective, or undesirable. EAT is an alternative therapy widely used by organizations, such as PATH International Equine Services, that endorse its effectiveness for treating a variety of mental health issues. These claims have drawn criticism because the published research contains glaring methodological flaws, making it difficult to assess how effective these therapies actually are (Anestis et al., 2014). Equine-assisted therapies present a unique treatment modality that might effectively treat PTSD, particularly for individuals who have difficulty with other treatment modalities. In EAT, a psychotherapist and equine specialist work together to help the patients negotiate interactions with a horse using structured interventions or activities.

Read the detailed description

In this pilot study the investigators will develop the EAT intervention and determine whether research methods (evaluation interviews, assessment measures, videotaping procedures) are acceptable to participants. Specifically, the investigators will focus on issues such as session length, appropriateness of the "content" for treatment of PTSD, ordering of session content, adherence to the manual of the equine therapeutic team (based on observations made during supervision and feedback from the consultants), and will detail logistics of data collection and how best to record the sessions (camera angles, etc.).
