Two interrelated cross-sectional studies were conducted to expand earlier findings about correlates of outwardly directed aggressive behavior in children with mental retardation. In Study 1 we compared children with mental retardation, 27 with and 23 without aggression. Aggression was best predicted by concurrent self-injurious behavior (SIB). In Study 2 we examined the likelihood that aggression was predicted by concurrent SIB and other nondestructive maladaptive behaviors in an archival cohort of 701 children younger than 21 with IQs below 70. Self-injurious behavior significantly predicted outwardly directed aggression for all children regardless of age. Additional predictors besides SIB showed only minimal improvements in model R2 values. Results were discussed in light of recent research proposing a common basis for aggression and SIB.
我们开展了两项相互关联的横断面研究，以拓展早期关于智力障碍儿童外向攻击性行为相关因素的研究结果。在研究1中，我们比较了智力障碍儿童，其中27名有攻击行为，23名没有攻击行为。同时存在的自伤行为（SIB）最能预测攻击行为。在研究2中，我们在一个档案队列中，对701名年龄小于21岁、智商低于70的儿童，研究了同时存在的自伤行为和其他非破坏性行为对攻击行为的预测可能性。无论年龄大小，自伤行为都能显著预测所有儿童的外向攻击行为。除自伤行为外的其他预测因素，仅使模型R2值有极小的提升。我们根据最近提出攻击行为和自伤行为有共同基础的研究对结果进行了讨论。
