Objective: To investigate the posttraumatic symptom of survivors in the "5.12" earthquake and its influencing factors.
Methods: Six hundred and five earthquake survivors from Beichuan District were interviewed by systematic sampling method. Posttraumatic symptoms and demographic source were measured using the PTSD Checklist Civilian Version (PCL-C) and self-questionnaire.
Results: The prevalence of PTSD is 11.2%. Survivors who suffer from PTSD commonly behave re-experiencing trauma and hyper arousal. The logistic regression shows that victims who have lost family members, who are females, and who suffered huge losses of property in this earthquake are the dangerous factors of PTSD. The results of OR are 2.848, 1.778 and 3.297 respectively.
Conclusion: Posttraumatic symptoms are still common among victims three years after "5.12" Earthquake. Some efficient measures regarding the different survivors should be taken. Victims who have lost family members, who are females, and who suffered huge losses of property, should be paid more attention. Re-experiencing trauma and hyper arousal are symptoms that deserve our main concern.
