The extent to which maternal depressive symptoms in the first 6 months of life is linked with internalizing and externalizing behaviors in childhood through specific insensitive maternal behaviors (unresponsive and overtly negative behaviors) was examined in a sample of 259 mother-infant dyads. In addition, the extent to which these paths were moderated by infant negative emotionality was also examined. Maternal depressive symptoms were assessed prenatally and when infants were 6 months and 2 years old. Maternal unresponsive and overtly negative behaviors and infant negative emotionality were observed when infants were 6 months old. Mothers reported on infant's internalizing and externalizing behaviors when infants were 2 years old. Maternal depressive symptoms were directly associated with higher internalizing behaviors; this path was not mediated by maternal behaviors. Depressive symptoms were unrelated to externalizing symptoms. Infant negative emotionality did not moderate these effects, but was related positively to overtly negative maternal behaviors, and temperament interacted with maternal depressive symptoms to predict unresponsive maternal behaviors. Results suggest that early maternal depressive symptoms, infant negative emotionality, and negative maternal behavior pose risk for infants' later internalizing behaviors, but the proposed moderated mediation model was not supported.
在259对母婴样本中，研究了婴儿出生后头6个月内母亲的抑郁症状通过特定的不敏感母亲行为（无反应和明显负面行为）与儿童内化和外化行为之间的关联程度。此外，还研究了这些路径受婴儿消极情绪调节的程度。在孕期、婴儿6个月大以及2岁时评估母亲的抑郁症状。在婴儿6个月大时观察母亲的无反应和明显负面行为以及婴儿的消极情绪。当婴儿2岁时，母亲报告婴儿的内化和外化行为。母亲的抑郁症状与较高的内化行为直接相关；这一路径不受母亲行为的介导。抑郁症状与外化症状无关。婴儿消极情绪并未调节这些影响，但与母亲明显的负面行为呈正相关，并且气质与母亲的抑郁症状相互作用以预测母亲的无反应行为。结果表明，早期母亲的抑郁症状、婴儿消极情绪和母亲负面行为会给婴儿日后的内化行为带来风险，但所提出的调节中介模型未得到支持。
