This study aimed to investigate the factors associated with parricide in patients with schizophrenia who committed homicide.
Among patients with schizophrenia who were in the National Institute of Forensic Psychiatry between November and December 2007, 88 patients who committed homicides were enrolled; 59 had committed parricide, and 29 had killed strangers. Medical charts, written expert opinions, written records of police or prosecutors, and court decisions were reviewed. Direct interviews with patients were also conducted.
Significant factors associated with parricide among homicidal patients with schizophrenia were living with the victim, female sex of the victim, and offense-provoking events including scolding, threatening forced hospitalisation, and forcing medication on the patient before the homicide. Capgras syndrome was present at a significantly higher rate in the parricide group than in the stranger group. Drug compliance at the time of the offence was low in both groups.
Untreated psychotic symptoms such as Capgras syndrome, living with elderly parents, especially mothers, and conflicts caused by victims' scolding, threatening forced hospitalisation, and forcing medication on the patients are associated with parricide among homicide offenders with schizophrenia.
本研究旨在探讨精神分裂症患者凶杀案中与杀亲相关的因素。
在 2007 年 11 月至 12 月间国立司法精神医学研究所收治的精神分裂症患者中，纳入了 88 名凶杀案患者；其中 59 名患者犯有杀亲罪，29 名患者杀害了陌生人。对患者的病历、书面专家意见、警察或检察官的书面记录和法庭判决进行了审查。还对患者进行了直接访谈。
与凶杀案中患有精神分裂症的杀亲患者相关的显著因素包括与受害者同住、受害者为女性、以及在凶杀案发生前有挑衅性事件，如责骂、威胁强制住院和强迫给患者服药。在杀亲组中，Capgras 综合征的发生率明显高于陌生组。在两组中，犯罪时的药物依从性均较低。
未经治疗的精神病症状，如 Capgras 综合征、与年老的父母同住，尤其是与母亲同住，以及因受害者责骂、威胁强制住院和强迫给患者服药而引发的冲突，与精神分裂症凶杀犯的杀亲行为有关。
