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.).
