| Based on the current situation about posttraumatic stress disorder, depression and resiliency, this study with the help of children's posttraumatic stress diagnostic scale (CPSS),Children's Depression Scale and other scales,the relation- ships among disaster exposure degree, resiliency, posttraumatic stress disorder and depression were explored among students from middle schools'of Wenchuan and Maoxian. SPSS16.0 were adopted to analyze the data, and multivariate analysis of variance, correlation analysis and multiple linear regression and so on were cond- ucted.The major findings were as follows:(1) The detection rate of PTSD and depreesion among middle school students in earthquake striken area is relatively high, respectively 45.26%, 76.86%, and girls were significantly higher than male students. In addition, level of PTSD has the greatest impact on student learning, followed by entertainment, leisure, while the least impact on the relationship among the family members. Gender and the degree of disaster exposure were the two main factors of PTSD and depression, the degree of disaster exposure and PTSD, depression showed a significant negative correlation.(2) The relationship between depression and PTSD were significantly negative related, and depression can predict the level of PTSD, depression play an intermediary role between the degree of disaster exposure and PTSD. (3) The overall level of resilience increase as the grades, senior school students'resilience was significantly higher than junior high school students'.In high-exposure group, the optimism level of the Tibetan students was significantly lower than the Han and Qiang; optimistic about the level of secondary school students with exposure to the escalation of the disaster,the optimistic level of Han showed a significant reduction in the degree of disaster exposure;while the optimistic level of Tibetan students was manifested as highest when the level of exposure was middle level; In addition, moderate levels of disaster exposure has the largest impact on the level of optimistic among the students from junior middle school.(4) Resilence can directly and indirectly reduce the degreed of PTSD and depre- ssion. Specifically, strength has a protective effect for PTSD, Intrusion, Avoidance, Hyper; while tenacity can reduce symptoms of traumatic experiences and strength, tenacity will change the degree of influence between subjective fear and PTSD. In addition, the overall level of resilience, strength, tenacity and optimism were played a protective role between the degree of depression and subjective fear. |
