Abstract:
This paper reviews the present literature examining how hope relates to PTSD and broader functioning after a trauma, including potential underlying mechanisms and significant factors impacting these relationships and the role of hope as a mechanism of change within interventions for PTSD. First, the ways in which trauma impacts hope are discussed. Afterwards, an overview is provided of cross-sectional and prospective research indicating that greater hope reduces the risk of PTSD and promotes positive outcomes of adversity. Next, potential underlying mechanisms and determinants of the relationship between hope and adjustment are explored, including adaptive appraisals, productive coping, and social support. Finally, evidence supporting the role of hope as a mechanism of change in treatments for PTSD is reviewed.
