Adolescent mothers often come from vulnerable backgrounds which might impact the quality of both maternal and infant behavior. Despite the negative impact of adolescent motherhood for maternal and infant behavior, social support may decrease the risks and promote maternal behavior toward the infant. The aim of this study was to investigate longitudinally the effects of proximal (maternal behavior) and distal (mother's perceived social support) variables on infant development in a sample of Brazilian adolescent mothers and their infants. Thirty-nine adolescent mothers (Mage=17.26years; SD=1.71) were observed interacting with their infants at 3 and 6 months postpartum and reported on social support. Results revealed that maternal and infant behavior were associated within and across times. Mothers' perceived social support at 3 months had an indirect effect on infant behavior at 6 months, totally mediated by maternal behavior at 6 months. Our findings revealed the mutual influence between maternal and infant behavior, revealing a proximal process. The results also underscored the importance of the passage of time in the interplay between mother-infant interactions and their developmental context.
青少年母亲往往来自弱势群体，这可能会影响母婴行为的质量。尽管青少年母亲身份对母婴行为有负面影响，但社会支持可能会降低风险并促进母亲对婴儿的行为。本研究的目的是纵向调查近端（母亲行为）和远端（母亲感知到的社会支持）变量对巴西青少年母亲及其婴儿样本中婴儿发育的影响。观察了39名青少年母亲（平均年龄=17.26岁；标准差=1.71）在产后3个月和6个月与婴儿互动的情况，并报告了社会支持情况。结果显示，母婴行为在不同时间内和不同时间之间都存在关联。母亲在3个月时感知到的社会支持对婴儿在6个月时的行为有间接影响，完全由母亲在6个月时的行为介导。我们的研究结果揭示了母婴行为之间的相互影响，揭示了一个近端过程。研究结果还强调了时间推移在母婴互动及其发展背景之间相互作用中的重要性。
