The way in which a mother and her preterm baby interact, especially in moments preceding or following stressful events, is fundamental in shaping the infant's autoregulation. Patterns of mutual sequential coordination constitute stress regulation competences and provide foundation for later socio-emotional development. Maternal affective touch has been postulated as an essential regulatory factor in early social exchange. In this study we aimed to better understand the interplay between maternal affective tactile behaviors and physiological synchrony between mother and child, with possible implications for early bonding processes. Fifteen mother-premature infant dyads were video-recorded during a free interaction and directly after a skin-interrupting medical procedure (vaccination or blood sampling) in the Neonatal Intensive Care Unit. The proportion of maternal affective touch was coded both in free and post-stress interactions. Parasympathetic response was assessed simultaneously in mothers and neonates in order to observe physiological synchrony in dyads. Finally, interactional misattunement during mothers' comforting actions and infant behavior after stress was evaluated as a potential indicator of risk in early bonding processes. Results indicated a positive association between the duration of maternal affective touch and adaptive autonomic synchrony patterns in dyads. Correlations were found between maternal affective touch both before and after stress-inducing procedure and several synchrony measures from free interaction phase (Spearman ρ = -0,57 do 0,72, p < 0,05) Additionally, the study revealed a positive correlation between the level of interactional misattunement and the duration of maternal affective touch after stress (ρ = 0,47, p < 0,05). The quality of synchrony was better in free interactions than during post-stress kangaroo care phase (p < 0,05).
母亲与早产婴儿的互动方式，尤其是在压力事件之前或之后的时刻，对于塑造婴儿的自我调节至关重要。相互顺序协调的模式构成了压力调节能力，并为后期的社会情感发展奠定了基础。母亲的情感触摸被假定为早期社会交流中的一个重要调节因素。在本研究中，我们旨在更好地理解母亲情感触觉行为与母婴生理同步之间的相互作用，及其对早期亲密关系形成过程的潜在影响。在新生儿重症监护病房，对15对母婴进行了自由互动期间以及皮肤穿刺医疗程序（接种疫苗或采血）刚结束后的视频记录。在自由互动和压力后互动中都对母亲情感触摸的比例进行了编码。同时评估母亲和新生儿的副交感神经反应，以观察二元组中的生理同步情况。最后，将母亲安慰行为期间的互动失调以及压力后婴儿的行为评估为早期亲密关系形成过程中风险的潜在指标。结果表明，母亲情感触摸的持续时间与二元组中适应性自主同步模式之间存在正相关。在压力诱导程序之前和之后的母亲情感触摸与自由互动阶段的几种同步测量之间都发现了相关性（斯皮尔曼ρ=-0.57至0.72，p<0.05）。此外，研究还发现互动失调程度与压力后母亲情感触摸的持续时间之间存在正相关（ρ=0.47，p<0.05）。自由互动中的同步质量优于压力后袋鼠式护理阶段（p<0.05）。
