Touch is a primary form of communication for mother-infant dyads in the infant's first year of life. Stressors such as intimate partner violence (IPV) and maternal depression experienced during the perinatal period may interfere with mother-infant touch via prenatal programming of the stress response and disrupted parenting. Mother-infant touch research typically focuses on maternal touch, while research on infant touch is limited. However, research suggests that infants sometimes lead interactive behavior, with mothers responding and adapting to their infants. Therefore, the aim of the present study was to examine the effects of IPV and maternal depression on infant-led touch interactions and maternal touch responses. Touch behaviors were coded in 174 mother-infant dyads while they engaged in a free play. ANCOVA analyses indicated that male infants with pre- or postnatal IPV exposure initiated more negative touch (e.g., hitting, kicking, pushing) with their mothers than female or nonexposed male infants. IPV did not predict differences in maternal touch responses to infants, while postpartum depressive symptoms were associated with maternal decreased touch responsiveness to male infant touch. The results suggest that male infant touch behavior is particularly susceptible to prenatal or postnatal exposure to IPV. Importantly, aggressive behavior in early childhood predicts more aggressive behavior across time, and these early negative touch behaviors may be indicative of the beginning of a trajectory of increased physical aggression into childhood, adolescence, and adulthood. Moreover, the results support extant findings that prenatal life is a sensitive period for postnatal development, including postnatal socially interactive behavior. Finally, depressed mothers of male infants exhibited decreased touch responsiveness, suggesting that depression may alter maternal interpretation of male infant cues, resulting in maternal withdrawal.
触摸是婴儿生命的第一年母婴对子的主要交流形式。压力源,如亲密伴侣暴力(IPV)和围产期经历的母亲抑郁,可能通过产前应激反应编程和育儿中断来干扰母婴触摸。母婴触摸研究通常侧重于母亲的触摸,而婴儿触摸的研究则有限。然而,研究表明,婴儿有时会主动进行互动行为,母亲会对其做出反应并适应他们。因此,本研究旨在探讨 IPV 和母亲抑郁对婴儿主导的触摸互动和母亲触摸反应的影响。在 174 对母婴对中,他们在自由玩耍时进行了触摸行为编码。ANCOVA 分析表明,与女性或未暴露的男性婴儿相比,经历过产前或产后 IPV 暴露的男婴与母亲的消极触摸(例如,打、踢、推)更多。IPV 并没有预测到母亲对婴儿触摸反应的差异,而产后抑郁症状与母亲对男婴触摸的反应性降低有关。结果表明,男婴的触摸行为特别容易受到产前或产后 IPV 的影响。重要的是,幼儿期的攻击行为预示着随着时间的推移会出现更多的攻击行为,这些早期的消极触摸行为可能表明攻击性增加的轨迹开始进入儿童期、青春期和成年期。此外,研究结果支持现有研究发现,产前生活是产后发展的敏感时期,包括产后社交互动行为。最后,患有抑郁的男婴母亲表现出触摸反应性降低,这表明抑郁可能会改变母亲对男婴线索的解释,从而导致母亲回避。
