Most of the relatively firm evidence on the causal significance of recent stressful life events in episodes of schizophrenia comes from a handful of retrospective case-control studies of schizophrenic patients and from comparisons of schizophrenic patients with patients suffering from affective disorders. Some important additional evidence is available from studies of the occurrence of psychotic symptomatology in extreme situations such as combat during wartime and in nonwesternized societies. On the basis of our analyses of the case-control studies, the literature on extreme situations, and the cross-cultural findings, we conclude that the consensus that stressful life events play only a trivial role in causing schizophrenic episodes is premature.
关于近期应激性生活事件在精神分裂症发作中的因果意义，大多数相对确凿的证据来自少数针对精神分裂症患者的回顾性病例对照研究，以及精神分裂症患者与情感障碍患者的比较研究。从对战时战斗等极端情况以及非西方化社会中精神病症状发生情况的研究中，可获得一些重要的额外证据。基于我们对病例对照研究、极端情况文献以及跨文化研究结果的分析，我们得出结论，认为应激性生活事件在引发精神分裂症发作中仅起微不足道作用的共识为时过早。
