title: A new psychological intervention: "512 Psychological Intervention Model" used for military rescuers in Wenchuan Earthquake in China.
abstract: OBJECTIVE
  We sought to compare the efficacy of the "512 Psychological Intervention Model" (that is, "512 PIM", a new psychological intervention) with debriefing on symptoms of post-traumatic stress disorder (PTSD), anxiety and depression of Chinese military rescuers in relation to a control group that had no intervention.
  
  
  METHODS
  We conducted a randomized controlled trial with 2,368 military rescuers 1 month after this event and then at follow-up 1, 2 and 4 months later to evaluate changes in symptoms of PTSD, anxiety and depression based on DSM-IV criteria, respectively.
  
  
  RESULTS
  Baseline analysis suggested no significant differences between the study groups. Severity of PTSD, anxiety and depression decreased over time in all three groups, with significant differences between the groups in symptoms of PTSD (P < 0.01). Compared with the debriefing and control group, significant lower scores of PTSD and positive efficacy in improving symptoms of re-experiencing, avoidance and hyperarousal were found in the "512 PIM" group.
  
  
  CONCLUSIONS
  "512 PIM" was an effective psychological intervention for military rescuers in reducing symptoms of PTSD, anxiety and depression after a crisis.
