To examine the prevalence of PTSD following homicide and investigate the relationship between PTSD from past traumas, defense styles and PTSD following homicide and psychiatric co-morbidity. 167 male homicide perpetrators participated in the study and completed the Posttraumatic Stress Diagnostic Scale, the General Health Questionnaire-28 and the Defense Styles Questionnaire. 45% met the criteria for PTSD following homicide and 55% for no-PTSD. With the number of times for imprisonment adjusted, regression analyses showed that immature defense style was associated with PTSD following homicide with the severity of PTSD from past traumas as a moderator. Neurotic and immature defense styles and PTSD from past trauma were significantly and independently associated with psychiatric co-morbidity. Homicide perpetrators could develop PTSD following homicide. The severity of PTSD from past traumas could affect PTSD following homicide and other psychological problems, and influence the effect of using immature defense against PTSD from homicide. Past trauma, immature and neurotic defense styles had a unique and specific pattern of influence on psychological symptoms, other than trauma symptoms.
调查凶杀后 PTSD 的流行情况，并探讨 PTSD 来自既往创伤、防御方式与凶杀后 PTSD 及精神共病之间的关系。方法：167 名男性凶杀犯参与了这项研究，他们完成了创伤后应激障碍诊断量表、一般健康问卷-28 和防御方式问卷。结果：45%的人符合凶杀后 PTSD 的标准，55%的人不符合。在调整入狱次数后，回归分析表明，不成熟的防御方式与凶杀后 PTSD 相关，既往创伤的 PTSD 严重程度为调节因素。结论：神经症性和不成熟的防御方式以及既往创伤的 PTSD 与精神共病显著且独立相关。凶杀犯可能会患上凶杀后 PTSD。既往创伤的 PTSD 严重程度可能会影响凶杀后 PTSD 及其他心理问题，并影响使用不成熟防御方式来对抗凶杀所致 PTSD 的效果。既往创伤、不成熟和神经症性防御方式对心理症状（除创伤症状外）有独特和特定的影响模式。
