Background: Older Veterans with Posttraumatic Stress Disorder (PTSD) are often socially isolated and have complex comorbid physical health problems. Aging-related stressors can exacerbate PTSD symptoms. These factors contribute to greater impairment in social functioning and decreased quality of life (QoL). Evidence-based psychotherapies for PTSD often address these issues, but not all older Veterans with PTSD seek help for these challenges, some don't want to engage in trauma-focused treatment, some drop out prematurely, and some still have residual symptoms upon completion. Thus, additional interventions that directly target social functioning among older Veterans with PTSD are needed.

Methods: In this paper we describe the development of and feasibility evaluation plan for, "Enhancing Social Functioning for older Veterans with PTSD (ESVP)," a social functioning group intervention for older (>60 years) Veterans with PTSD. This project involved four phases of work: 1) Intervention development, 2) Review of intervention and potential modifications using focus groups, 3) Intervention pilot testing and modification, and 4) A randomized feasibility trial comparing the intervention with a support group control. Intervention modules address interpersonal relationships, effective communication, anger management, social skills, social support/activities, and behavioral activation.

Conclusion: This project details the iterative process used to develop the ESVP intervention designed to enhance social functioning in older Veterans with PTSD, and to evaluate feasibility. Analyses are underway to examine feasibility of conducting ESVP with a sample of older Veterans with PTSD. Findings from the final project phase, the randomized feasibly trial, will inform the design and implementation of a future trial. CLINICALTRIALS: gov Identifier: NCT02803125.
