基于个体的某些特征可能是易感因素，环境压力因素可能导致易感个体的精神病发作，提出了一种暂定的精神分裂症精神病发作模型。某些信息处理缺陷、自主反应异常、社会能力和应对限制被视为潜在的脆弱性因素。离散生活事件形式的压力源以及普遍的社会环境压力水平被视为与先前存在的脆弱性特征相互作用产生恶性循环的因素，而恶性循环又导致精神病发作。建议区分稳定易感因素、中介易感因素和发作指标，以区分易患或表现为精神分裂症的个体的异常类型。一些主要领域的未解决的问题，有关这一观点的精神分裂症精神病发作进行了讨论。（PsycINFO数据库记录(c) 2016 APA，版权所有）
A tentative model of schizophrenic psychotic episodes is presented, based on the evidence that certain characteristics of individuals may serve as vulnerability factors and that environmental stressors may precipitate psychotic periods in vulnerable individuals. Certain information-processing deficits, autonomic reactivity anomalies, and social competence and coping limitations are viewed as potential vulnerability factors. Stressors in the form of discrete life events as well as the prevailing level of social environmental stress are seen as factors that interact with preexisting vulnerability characteristics to produce vicious circles, which lead, in turn, to psychotic episodes. A distinction among stable vulnerability factors, mediating vulnerability factors, and episode indicators is suggested to differentiate types of abnormalities that characterize individuals prone to or manifesting schizophrenic disorder. Some major areas of unresolved questions in relation to this view of schizophrenic psychotic episodes are discussed.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
