Abstract:
Social support after a traumatic event is linked to posttraumatic stress disorder (PTSD). However, little is known about the ways in which social support influences the adaptation to trauma and development of PTSD. The aim of the present article is threefold: to outline the various processes by which social support is linked to PTSD, to review the most relevant research in the field, and to suggest potential future research.
