产妇创伤是一个复杂的危险因素，与不良儿童结局有关，但这种关联背后的机制尚不清楚。这项研究包括收养家庭和亲生家庭，研究了母亲创伤和相关抑郁症状与儿童内化和外化行为之间的遗传和环境机制。使用通径分析来分析 541 个养母-养子 (AM-AC) 二人组和 126 个亲生母亲-亲生子 (BM-BC) 二人组的数据；这两种家庭类型通过同一个亲生母亲联系在一起。在AM-AC和BM-BC二元组中，养育母亲的创伤与孩子的内化和外化行为有关，这种关联是由养育母亲的抑郁症状介导的，但亲生孩子的外化行为除外，亲生母亲的创伤对其有直接影响。在仅共享环境的二人组（即 AM-AC 二人组）中，母亲创伤与儿童行为之间存在显着关联，这表明环境机制对母亲创伤有影响。在仅与遗传相关、没有共享环境的二人组中（即 BM-AC 二人组），还观察到母亲抑郁症状与儿童内化和外化行为之间存在显着关联，这表明通过母亲抑郁症状产生影响的遗传途径。
Maternal trauma is a complex risk factor that has been linked to adverse child outcomes, yet the mechanisms underlying this association are not well understood. This study, which included adoptive and biological families, examined the heritable and environmental mechanisms by which maternal trauma and associated depressive symptoms are linked to child internalizing and externalizing behaviors. Path analyses were used to analyze data from 541 adoptive mother–adopted child (AM–AC) dyads and 126 biological mother–biological child (BM–BC) dyads; the two family types were linked through the same biological mother. Rearing mother’s trauma was associated with child internalizing and externalizing behaviors in AM–AC and BM–BC dyads, and this association was mediated by rearing mothers’ depressive symptoms, with the exception of biological child externalizing behavior, for which biological mother trauma had a direct influence only. Significant associations between maternal trauma and child behavior in dyads that share only environment (i.e., AM–AC dyads) suggest an environmental mechanism of influence for maternal trauma. Significant associations were also observed between maternal depressive symptoms and child internalizing and externalizing behavior in dyads that were only genetically related, with no shared environment (i.e., BM–AC dyads), suggesting a heritable pathway of influence via maternal depressive symptoms.
