title: Peritraumatic reactions associated with the World Trade Center disaster.
abstract: OBJECTIVE
  The World Trade Center disaster was of unprecedented magnitude and impact in U.S. history. The authors conducted a pilot survey investigating these effects.
  
  
  METHODS
  A questionnaire regarding the disaster was sent to responders to an advertisement. It included demographic and disaster-exposure questions and three scales applied to "during and shortly after" the disaster.
  
  
  RESULTS
  Despite widely ranging exposure, scores for distress (Peritraumatic Distress Inventory), dissociation (Peritraumatic Dissociative Experiences Questionnaire), and posttraumatic stress (Impact of Event Scale-Revised) were markedly elevated (N=75). After covariance for exposure, the distress factor of loss of control most strongly predicted both early dissociation and posttraumatic stress. Life threat specifically contributed to arousal. Dissociation did not contribute beyond distress to posttraumatic stress, with the exception of re-experiencing.
  
  
  CONCLUSIONS
  This survey of reactions to the World Trade Center disaster revealed high levels of early symptoms and suggested similar but independent pathways toward dissociation and posttraumatic stress.
