[Factors that influence comorbidity from panic disorder and PTSD after earthquakes].

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).

METHOD: 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.
