Objective:To explore the prognosis of posttraumatic stress disorder (PTSD) in flood survivors 13 years after they had been diagnosed with PTSD symptoms,and investigate the relationship between their personality traits and the prognosis of PTSD.Method:In this cross-sectional study,the survivors of Dongting Lake flood in 1998-1999 in Hunan in China,who were investigated and screened as PTSD symptoms positive in 2000 were selected as the target population,from which a sample of 200subjects was drawn using amulti-stage random sampling method.The Posttraumatic Stress Disorder Scale Civilian Version (PCL-C) was used to examine and re-screen the participants of PTSD symptoms in order to explore the prognosis of PTSD.Participants whose PCL-C scores were equal to 44 or higher were classified as the PTSD symptoms positive group,while those with PCL-C scores less than 44 were classified as the recovered group.Personality traits were then assessed,using the Revised Eysenck Personality Questionnaire Short Scale for Chinese (EPQ-RSC),in both the recovered group and the PTSD symptoms positive group.Finally,the multivariate logistic regression analysis was used to investigate the relationship between the prognosis of PTSD and personality traits.Results:Totally 200 subjects were eligible for this study and completed the questionnaires,but 16 of them had their questionnaires excluded from data analysis because they provided incomplete information.Thus,the response rate was 92.0％.According to the PCL-C's cut-off score,22 participants were still screened as PTSD symptoms positive and were classified as the PTSD symptoms positive group,whereas the other 162 participants were screened as PTSD symptoms negative and were classified as the recovered group.Compared with the recovered group,the EPQ-RSC extroversion scores for the PTSD symptoms positive group were significantly lower [(51.8 ± 10.7) vs.(45.1 ± 13.2),P ＜ 0.05] and their neuroticism scores were significantly higher [(46.5 ± 10.1) vs.(58.3 ± 12.2),P ＜ 0.05].The multivariate logistic regression analysis showed,after adjusting for the variables such as gender and age,that higher neuroticism (OR ＝ 3.63,95％ CI:1.05 -12.54) was a risk factor for the persistent PTSD symptoms in the flood survivors.Conclusions:It suggests that neuroticism is associated with prognosis of PTSD in flood survivors,those with higher neuroticism scores appear to have problems to recover from PTSD.%目的:了解洪灾13年后创伤后应激障碍症状阳性者的预后情况,以及人格特征与创伤后应激障碍预后的关系.方法:本研究为横断面研究,采用多阶段随机抽样法,对200例经历1998-1999年湖南省洞庭湖区特大洪灾且经2000年流行病学调查被归类为创伤后应激障碍症状阳性的灾民再次进行调查.采用创伤后应激障碍量表平民版(PCL-C)对创伤后应激障碍再次进行筛查,实际入组184例,将研究对象分为康复组(n＝ 162例)和PTSD症状阳性组(n＝22例);采用艾森克人格问卷简式量表中国版(EPQ-RSC)测查两组的人格特征.用logistic回归模型分析人格特征与创伤后应激障碍预后的关系.结果:洪灾13年后PTSD症状持续阳性比率为12.0％ (22/184).康复组EPQ-RSC外向人格得分高于PTSD症状阳性组[(51.8±10.7) vs.(45.1±13.2),P＜0.05],神经质人格得分低于PTSD症状阳性组[(46.5±10.1) vs.(58.3±12.2),P＜0.05].Logistic回归分析显示,在调整性别、年龄等变量后,神经质高是创伤后应激障碍症状持续阳性的危险因素(OR＝ 3.63,95％CI:1.05～ 12.54).结论:洪灾后创伤后应激障碍症状阳性持续存在的情况值得重视,神经质人格与创伤后应激障碍预后相关.
