Posttraumatic stress disorder(PTSD), which has a life prevalence of 1%, can occur after
exposure to a traumatic event that carries the risk of severe injury or death to self.
The characteristic clinical features of PTSD are reexperiencing the events, increased arousal,
and persistent avoidance or numbing of responsiveness. Authors reported that four survivors
from Sampoong collapse suffered from symptoms of PTSD, guilty feeling, depressed mood,
panic symptoms, claustrophobia, and suicidal threat since their injuries.
Interestingly, the psychotic symptom scale in self rating SCL-90-R(symptom
checklist-90-revision) was somewhat high(<65) in three of them.
