A sample of child guidance clinic cases with a young adult onset of schizophrenia were followed into middle age. Outcome ratings and marital status were used as predictive criteria for childhood measures of IQ, aggressiveness, and severity of disturbance. The interaction of IQ and levels of aggressive symptomatology revealed a subgroup of preschizophrenics with low IQ and below average aggressiveness who had disproportionately unfavorable adult outcomes and never-married status. The results demonstrated the important moderating effects of a second variable on the predictive statements made about an initial predictor.
对一组青少年期起病的精神分裂症儿童指导诊所病例进行了追踪，直至中年。将结果评分和婚姻状况用作儿童期智商、攻击性和障碍严重程度测量指标的预测标准。智商与攻击症状水平的相互作用揭示了一个亚组的精神分裂症前驱者，他们智商低且攻击性低于平均水平，成年后的结果异常不利且从未结婚。结果表明了第二个变量对关于初始预测因素所做预测陈述的重要调节作用。
