This proposed project is composed of two phases. In Phase I, the investigators will produce an intervention and accompanying manual for the PTSD version of ESS (ESS-P), based upon the strategies and structure of the existing ESS intervention. To this end, the investigators will interview Veterans with a PTSD diagnosis to learn more about their experience with societal and internalized stigma associated with PTSD, plus other considerations and issues in addressing internalized stigma with such Veterans. Information gleaned in these qualitative interviews will form the basis of the investigators' adaption of the ESS intervention to specifically address the needs of Veterans with PTSD. In Phase II, the investigators will pilot-test ESS-P with Veterans who have PTSD, to evaluate the feasibility and acceptability of the intervention. In addition, the investigators will preliminarily estimate the effects of ESS-P through comparison to a control group receiving only an informational brochure on internalized stigma associated with PTSD. These feasibility, implementation and pilot outcome data will be used to further refine the intervention, towards the goal of conducting a future larger scale study of ESS-P within the VA system.
