title: [Factors that influence comorbidity from panic disorder and PTSD after earthquakes].
abstract: OBJECTIVE
  After the earthquake and tsunami in Chile (F-27), we studied the effect of socio-demographic factors, exposure to the event, and state aid received on comorbidity from panic disorder (PD) and posttraumatic stress disorder (PTSD).
  
  
  METHODS
  Surveys that include the administration of the Davidson Trauma Scale (DTS) to 246 inhabitants.
  
  
  RESULTS
  19.1 % comorbidity was found (r=.583, R2=.340, p<.01). Females homeowners have a higher risk of PD and PTSD. State aid is associated with more cases of PD.
  
  
  CONCLUSIONS
  We designed risk/resistance profilesagainst earthquakes/tsunamis and an instrument to detect cases at risk of PTSD. We suggest guidelines so that the government can improve its role after disasters.
