Studies of live events and schizophrenia are few. Most have such methodological limitations that make any causal interpretation of their findings impossible. Of the three studies with appropriate methodology and controls, Brown and Birley (1968) found very recent life events trigger onset, Leff et al. (1983) found events were capable of precipitating relapse, under certain restricted circumstances, while Jacobs and Myers (1976) found independent events appear to have no significant effect. The widely held view that life events can precipitate schizophrenic episodes may be supported by our own clinical impressions; it is as yet not well supported by empirical data. Future research should perhaps focus on other definitions of these psychoses, such as is now embraced by DSM-III. Perhaps then a relation between stressful events and some of the non-depressive functional psychoses might be demonstrated.
关于现实生活事件与精神分裂症的研究很少。大多数研究存在方法学上的局限性，使得无法对其研究结果进行任何因果解释。在三项采用适当方法和对照的研究中，布朗和伯利（1968年）发现近期的现实生活事件会引发发病，莱夫等人（1983年）发现，在某些特定情况下，事件能够促使复发，而雅各布斯和迈尔斯（1976年）发现独立事件似乎没有显著影响。生活事件可促使精神分裂症发作这一广泛持有的观点可能得到了我们自身临床印象的支持；但目前尚未得到实证数据的充分支持。未来的研究或许应聚焦于这些精神病的其他定义，比如现在《精神疾病诊断与统计手册》第三版所采用的定义。或许到那时，压力事件与某些非抑郁性功能性精神病之间的关系就能够得到证实。
