The study examines a sample of 120 male special hospital patients whose index offence was one of homicide. Demographic, criminological and psychiatric details are described and the characteristics of those committing psychotic and non-psychotic homicides are compared. The results generally confirmed most of the findings reported in international studies of abnormal homicide. Compared with other studies on in-patient populations we found a greater than expected proportion of non-psychotic homicide offenders, the majority of whom had a clinical diagnosis of personality disorder. Key factors distinguishing psychotic from non-psychotic homicide included a pre-offence criminal history, the objective relationship between perpetrator and victim and the behaviour after the offence. Psychotic men were less likely to have a prior history of criminality and substance abuse than their non-psychotic pears but they were more likely to have had previous contact with the psychiatric services and to have known their victims. Compared with the non-psychotic group the majority of psychotic offenders remained at the crime scene or summoned help. A marked age differential between psychotic and nonpsychotic offenders was not apparent in this study.
该研究对120名男性专科医院患者进行了抽样调查，这些患者的初次犯罪均为杀人罪。文中描述了他们的人口统计学、犯罪学和精神病学细节，并比较了实施精神病性杀人及非精神病性杀人者的特征。研究结果总体上证实了国际上关于异常杀人研究报告中的大部分发现。与其他针对住院人群的研究相比，我们发现非精神病性杀人罪犯的比例高于预期，其中大多数人临床诊断为人格障碍。区分精神病性杀人和非精神病性杀人的关键因素包括犯罪前科、犯罪者与受害者之间的客观关系以及犯罪后的行为。与非精神病性杀人者相比，精神病性杀人的男性有犯罪和药物滥用前科的可能性较小，但他们更有可能曾接触过精神科服务且认识受害者。与非精神病性组相比，大多数精神病性犯罪者留在犯罪现场或寻求帮助。在本研究中，精神病性和非精神病性犯罪者之间没有明显的年龄差异。
