Drawing on theories of attachment and family instability, this study examined associations between early mother-child separation and subsequent maternal parenting behaviors and children's outcomes in a sample of 2080 families who participated in the Early Head Start Research and Evaluation Project, the vast majority of whom were poor. Multiple regression models revealed that, controlling for baseline family and maternal characteristics and indicators of family instability, the occurrence of a mother-child separation of a week or longer within the first two years of life was related to higher levels of child negativity (at age three) and aggression (at ages three and five). The effect of separation on child aggression at age five was mediated by aggression at age three, suggesting that the effects of separation on children's aggressive behavior are early and persistent.
本研究借鉴依恋和家庭不稳定理论，在参加早期开端研究和评估项目的 2080 个家庭样本中，考察了早期母婴分离与随后的母性育儿行为和儿童结果之间的关系。这些家庭绝大多数都很穷。多元回归模型显示，在控制基线家庭和母亲特征以及家庭不稳定指标的情况下，生命头两年内发生一周或更长时间的母婴分离与儿童的消极性（三岁时）和攻击性（三岁和五岁时）水平较高有关。分离对五岁儿童攻击性的影响是通过三岁时的攻击性来介导的，这表明分离对儿童攻击行为的影响是早期的、持续的。
