Brief Summary

Veterans with PTSD often have impaired social relationships and poor social support. The negative outcomes associated with poor social support are of particular concern for Veterans with PTSD, who often perceive the world to be dangerous, view their social support network as a threat to their safety, and avoid members of their support network in order to increase their perceived safety. The goal of this project is to evaluate the efficacy of Acceptance and Commitment Therapy to Improve Social Support for Veterans with PTSD (ACT-SS), a treatment focused on helping Veterans with PTSD to increase social support with family relationships, partners, and peers by targeting maladaptive patterns of interpersonal difficulties, feelings of detachment from others, irritability, and avoidance of social situations. The primary aim of this study is to conduct a two-site randomized controlled trial of ACT-SS (n=75) vs. PCT (n=75), a common treatment for social support difficulties. If positive, this study will provide a critically-needed treatment for Veterans with PTSD to improve their social functioning and social reintegration in the community.

Outcome Measures

Primary Outcomes (2)

  • Change in the Social Adjustment Scale-Self Report

    The Social Adjustment Scale-Self Report (SAS-SR) is a 54-item measure of current social functioning in 6 domains: Work; Social and Leisure; Extended Family; Primary Relationship; Parental; and Family Unit. The Social and Leisure scale is the primary measure of change in social functioning for the study. Lower scores indicate better functioning. Scores on this scale range from 1-5.

    Baseline, End of Treatment (12 weeks), 3-month follow-up, and 6-month follow-up

  • Change in the MOS Social Support Survey

    Social Support: The MOS Social Support Survey is a 19-item multidimensional, self-administered survey of social support for individuals with chronic conditions. It includes four functional support scales, including emotional/informational, tangible, affectionate, and positive social interaction. A higher score for an individual scale or for the overall support index indicates more support. Scores range from 1-5.
