这项调查以 9 至 13 岁（N=281）为样本，考察了通过教师评分衡量的社会和身体攻击行为的发展轨迹。首先分别估计这两种形式的攻击轨迹，然后联合估计。总体样本的社会攻击性和身体攻击性的平均水平随着时间的推移而下降，但个体轨迹的变化很大。亚群体在社交和身体攻击方面都表现出较高的轨迹。联合估计产生了六种轨迹：低稳定、低增长、中增长、中除姐妹、高除姐妹和高增长。高增长群体的成员是由男性、未婚父母、非裔美国人以及母亲专制和宽容的养育方式预测的。宽容的养育方式也预示着中等增长群体的成员资格。这是第一个纵向研究整个发育时期的社会攻击行为的研究之一。尽管这些结果挑战了社会攻击行为在青春期早期达到顶峰的说法，但研究结果强调了在试图理解攻击行为的起源和结果时考虑不同发展轨迹的重要性。
For a sample followed from age 9–13 (N=281), this investigation examined developmental trajectories for social and physical aggression as measured by teacher ratings. Trajectories for both forms of aggression were estimated first separately, then jointly. Mean levels of both social and physical aggression decreased over time for the overall sample, but with high variability of individual trajectories. Subgroups followed high trajectories for both social and physical aggression. Joint estimation yielded six trajectories: low stable, low increasers, medium increasers, medium desisters, high desisters, and high increasers. Membership in the high increaser group was predicted by male gender, unmarried parents, African American ethnicity, and maternal authoritarian and permissive parenting. Permissive parenting also predicted membership in the medium increaser group. This is one of the first studies to examine social aggression longitudinally across this developmental period. Though the results challenge the claim that social aggression is at its peak in early adolescence, the findings emphasize the importance of considering different developmental trajectories in trying to understand origins and outcomes of aggression.
