地震情景再现对灾民创伤后应激障碍影响

Effect of reliving of earthquake on PTSD among disaster-stricken people of Wenchuan earthquake

目的了解汶川地震情景再现对灾民创伤后应激障碍的影响。方法先用创伤后应激障碍自评量表(PTSD-ss)和受灾暴露情况调查表对188名灾民测试,灾民观看短片"无情的地震"之后,再用前测量表进行即时测试。结果短片前测的PTSD-ss量表总分、主观评定、反复重现、警觉性提高得分分别为(42.87±20.27)、(3.43±1.89)、(11.96±7.11)、(7.80±5.71)分,均低于观看短片后测试得分(48.18±14.62)、(4.07±1.46)、(15.77±5.48)、(12.35±4.55)分,差异均有统计学意义(P<0.05)。结论地震情景再现可能会增强灾民创伤后应激障碍程度,但对回避等症状以及人身受伤害灾民的创伤后应激障碍却有一定的疗效。

Objective To examine the effects of earthquake reliving on post-traumatic stress disorder（PTSD） among the disaster-stricken people of Wenchuan earthquake.Methods Totally 188 disaster-stricken persons were tested with Post-traumatic Stress Disorder-self scoring（PTSD-ss） before and after a short film watching and were investigated with a questionnaire on the earthauake exposure conditions.Results Before watching the short film,the total score for PTSD-ss,the scores for subjective evaluation,reappearance,and alertness were 48.27±20.27,3.43±1.89,11.96±7.11,and 7.80±5.71,respectively,and obviously lower than those of after watching the film（48.18±14.62,4.07±1.46,15.77±5.48,and 12.35±4.55,respectively） with significant differences（P0.05 for all） among the disaster-stricke people.Conclusion The reliving of earthquake maybe strengthen PTSD symptoms among disaster-stricken people,but it has therapeutic effect on some PTSD symptoms such as avoidance for disaster-stricken people.
