This study aimed to investigate the relationship between dissociative experiences, post-traumatic stress disorder (PTSD), and psychiatric symptoms exhibited by schizophrenic patients 35 years after the Tangshan earthquake.
Seventy-one schizophrenic patients who had experienced the Tangshan earthquake were selected and evaluated by the Post-traumatic Dissociative Experience Questionnaire (PDEQ), thPTSD Checklist-Civilian Version (PCL-C), and the Positive and Negative Symptom Scale (PANSS).
The score of Group B (re-experiencing symptoms) in PCL-C was significantly positively correlated with age and significantly negatively correlated with the course of schizophrenia. Both gender and marriage were significantly positively correlated with the score of PCL-C Group D (irritability symptoms caused by hyperarousal). The PDEQ score was negatively correlated with thecourse of schizophrenia and positively correlated with the presence of sleep difficulties. Significant differences were found between the PCL-C scores of the positive and negative symptoms of the three core symptom groups; the positive rate of Group B was significantly higher than that of Group D, and the positive rate of Group C was significantly higher than that of Group D. The PCL-C total score was positively correlated with the negative symptom factor score of PANSS; Group C's symptoms were significantly negativelycorrelated with the positive factor score of PNASS; andGroup D's' symptoms were significantly negatively correlated with the PANSS total score and the positive factor score.
When consiering patients with schizophrenia post the Tangshan earthquake, age, gender, and marital status were all positively correlated with PTSD. The course of schizophrenia was negatively associated with PTSD and dissociative experiences. PTSD was positively correlated with the negative symptoms of schizophrenia and negatively correlated with the positive symptoms of schizophrenia. Thus, the conditions and symptoms of PTSD may interact with those of schizophrenia.
本研究旨在探讨唐山地震 35 年后精神分裂症患者的分离体验、创伤后应激障碍（PTSD）和精神症状之间的关系。
选取 71 例经历过唐山地震的精神分裂症患者，采用创伤后分离体验问卷（PDEQ）、创伤后应激障碍检查表-平民版（PCL-C）和阳性和阴性症状量表（PANSS）进行评估。
PCL-C 组 B（再体验症状）评分与年龄呈显著正相关，与精神分裂症病程呈显著负相关。性别和婚姻状况与 PCL-C 组 D（高唤醒引起的易怒症状）评分呈显著正相关。PDEQ 评分与精神分裂症病程呈负相关，与睡眠困难呈正相关。三组核心症状的 PCL-C 评分存在显著差异；组 B 的阳性率明显高于组 D，组 C 的阳性率明显高于组 D。PCL-C 总分与 PANSS 阴性症状因子评分呈正相关；组 C 的症状与 PANSS 阳性因子评分呈显著负相关；组 D 的症状与 PANSS 总分和阳性因子评分呈显著负相关。
在考虑唐山地震后精神分裂症患者时，年龄、性别和婚姻状况与 PTSD 呈正相关。精神分裂症病程与 PTSD 和分离体验呈负相关。PTSD 与精神分裂症的阴性症状呈正相关，与精神分裂症的阳性症状呈负相关。因此，PTSD 的情况和症状可能与精神分裂症的情况和症状相互作用。
