Results of three separate studies comparing adult schizophrenic and other psychiatric patients suggest that premature death of a parent may be a contributing factor in the etiology of schizophrenia. This finding was not attributable to a genetically-linked tendency toward suicide in parents. Parental death was found to occur earlier among schizophrenics than other patients and, in two studies, to be most frequent among schizophrenics with predominantly paranoid symptoms.
三项针对成年精神分裂症患者和其他精神疾病患者的独立研究结果表明，父母过早离世可能是精神分裂症病因中的一个促成因素。这一发现并非归因于父母中存在与基因相关的自杀倾向。研究发现，精神分裂症患者的父母死亡时间早于其他患者，并且在两项研究中，主要有偏执症状的精神分裂症患者中父母死亡的情况最为常见。
