Research Traumatic Event Memory Content Changes After A Trauma

Object: To acquaintance the change of the wounded about memory content of a trauma event,and the correlation between changes of the occurrence of PTSD after trauma. Methods: 1.The object of research: 100 participants with met the standard of trauma group and 100 individuals who had neither experienced significant trauma nor met criteria for current PTSD were collected who came from the first affiliated hospital of medical college of Shihezi university between September 2013 and December 2014. 2.The tools of research: General information questionnaire, the Chinese Wechsler memory scale-revised(WMS-RC), Posttraumatic Stress Disorder Check-list-Civilian Version(PCL-C), Eysenck personality Questionnaire(EPQ). 3.The implementation process: collected 100 individuals with met the standard of trauma group and 100 individuals with met the standard of control group.Trauma group filled in the general data questionnaire、EPQ and evaluated the individuals’ memory function with CWM-RC in seventh days after experienced trauma. However, control group filled in the general data questionnaire、EPQ evaluated the participants’ memory function with CWM-RC when into the group. Follow up the general information questionnaire to all individuals in 14 days、30 days、60 days and 90 days, and follow up PCL-C questionnaire in 30 days,and again evaluated the participants’ memory function with CWM-RC in 90 days. 4.Statistical analysis: The establishment of a database, using SPSS17.0 statistical software for data processing, all tests were two-sided test, the level of a =0.05. Result: 1.No significance in the general information and EPQ scale scores between trauma group and the control group(P>0.05). 2.At different time points, compared the CWM-RC of each memory subtest comparison between the two groups. In the first measured, significance(P <0.05) in visual recognition,visual reproduction, associative memory,tactile memory,intelligent memory,immediate memory between trauma group and the control group. However, 90 days again measured two groups of each memory subtest, no significant(P>0.05) in two groups of each memory subtest. But at different time points, significance(P <0.05) in experience, picture memory, visual recognition,visual reproduction, associative memory,tactile memory,intelligent memory,immediate memory between the two groups.3.Trauma group and control group on the memory contents are changed, only increase in the number of memory content trauma group and reduce the PTSD. 4.Image memory and emotional memory group in PTSD, but no statistical difference between two groups. 5.After four times follow-up, significance(P <0.05) in the distribution of two groups’ total deviation frequency; and significance(P <0.05) in the distribution of the two groups’ different frequency deviation of individual number; and significance(P <0.05) in the distribution of the two groups’ deviation individual number. 6.Comparison of PCL-C scores between the trauma group and the control group in the second follow-up, no significance in PCL-C scores between the two groups. And, no significance in PCL-C scores between memory bias and memory non deviation of the two groups. However, significance(P<0.05)in PCL-C scores between memory bias of the trauma group and memory bias of the control group, but no significance in PCL-C scores between memory non deviation of the trauma group and memory non deviation of the control group. 7. Within 90 days after trauma, 6 individuals grew into PTSD in 100 individuals of trauma group; there is no participant development of PTSD in 100 participants of control group. The probability of occurrence of PTSD is 6% in trauma group. Further, there are 6 participants development of PTSD in memory deviation 88 participants of trauma group, so the probability of occurrence of PTSD is 6.82%. Conclusion: 1. After a trauma, a wounded memory function obvious drop in short time, but after 90 days, the memory function almost recovered to the normal level. 2. PTSD patients mainly from memory content increase and decrease 3. People with PTSD mainly from image and emotional memory. 4.The individuals experienced trauma had higher PCL-C scores compared to the normal participants. The trauma experienced and memory bias participants had higher PCL-C scores relative to the normal of memory bias individuals. And, there is significant difference. 5.The individuals experienced trauma and appeared memory bias have a certain relationship to PTSD.
