Comparative Study
Incidence and prediction of posttraumatic stress disorder symptoms in severely injured accident victims.
This study was designed to assess the incidence of posttraumatic stress disorder (PTSD) in severely injured accident victims and to predict the presence of PTSD symptoms at a 12-month follow-up. ⋯ In severely injured accident victims who were healthy before experiencing trauma, the incidence of PTSD was low. One-third of the variance of PTSD symptoms at 1-year follow-up could be predicted by mainly psychosocial variables.
