ABSTRACT

We examined effects of maternal and child lifetime traumatic stress exposures, infant temperament, and caregiving quality on parent ratings of preschoolers’ executive functioning (EF). Maternal lifetime trauma was associated with preschoolers’ EF problems; this association was mediated by greater child trauma exposure. Infant temperament was associated with EF abilities, particularly among females. Among males, infant extraversion/surgency mediated the association of maternal lifetime trauma with poorer child EF. Caregiving quality was negatively associated with maternal and child trauma exposures but did not predict child EF. Findings have implications for interventions to identify children at risk for poor EF and optimize outcomes.

摘要

我们检查了母亲和儿童一生的创伤性应激暴露、婴儿气质和照顾质量对学龄前儿童执行功能 (EF) 家长评级的影响。母亲一生的创伤与学龄前儿童的 EF 问题有关；这种关联是由更多的儿童创伤暴露所介导的。婴儿气质与 EF 能力相关，尤其是在女性中。在男性中，婴儿外向性/外向性介导了母亲终生创伤与较差儿童 EF 的关联。护理质量与母婴创伤暴露呈负相关，但不能预测儿童 EF。研究结果对识别处于 EF 差风险中的儿童并优化结果的干预措施具有影响。
