Subjects who were initially free of psychological symptoms completed life event and symptom measures on 3 subsequent occasions 4 months apart. As expected, an association was found between symptoms and life events reported as occurring in the previous 4 months. A path analysis model was then constructed. The association between symptoms and events of the previous 4 months remained, but in neither panel did events reported as occurring more than 4 months previously predict symptoms.
最初没有心理症状的受试者在随后的3次场合中完成了生活事件和症状测量，每次间隔4个月。正如预期的那样，在症状与报告发生在之前4个月内的生活事件之间发现了一种关联。然后构建了一个路径分析模型。症状与之前4个月事件之间的关联依然存在，但在两个小组中，报告发生在4个月以前的事件均未预测到症状。
