经历虐待在幼儿期预测不良的副交感神经调节，其特征是低基线副交感神经活动和强烈的副交感神经的影响，在响应任务的撤回。促进第一关系（PFR）计划提高了父母对被认定为虐待家庭中幼儿的敏感性。使用随机对照试验的子样本，我们研究了父母参与PFR是否对幼儿的副交感神经调节产生持久影响，通过呼吸性窦性心律失常（RSA）测量，相对于资源和转诊控制条件。此外，我们还研究了父母的敏感和反应行为是否介导或调节了父母治疗组与儿童RSA之间的关联。在完成治疗6个月后，对29个PFR条件下的家庭和30个对照条件下的家庭进行了家访，并在基线和5个中等挑战性任务期间评估了幼儿的RSA。各组在基线RSA方面没有差异，但在RSA对任务的反应性方面存在差异。在不同的任务中，父母在控制条件下的幼儿比父母在PFR条件下的幼儿表现出更大的RSA下降。父母的行为与父母在PFR与对照条件下的幼儿的RSA变化表现出不同的关联，PFR治疗预测RSA变化范围从小幅度减少到增加，在治疗后6个月内表现出最敏感，反应性行为的父母的幼儿。这项初步研究表明，同样的干预措施，改善养育也改善幼儿的副交感神经调节，以应对日常活动，进一步的实验研究。
Experiencing maltreatment in early childhood predicts poor parasympathetic regulation, characterized by low baseline parasympathetic activity and strong withdrawal of parasympathetic influence in response to tasks. The Promoting First Relationships® (PFR) program improves parental sensitivity toward young children in families identified as maltreating. Using a subsample from a randomized control trial, we examined whether parental participation in PFR had lasting effects on toddlers’ parasympathetic regulation, as measured by respiratory sinus arrhythmia (RSA), relative to a resource and referral control condition. In addition, we examined whether parental sensitive and responsive behavior mediated or moderated associations between parent treatment group and children’s RSA. More than 6 months after completing treatment, 29 families in the PFR condition and 30 families in the control condition were visited at home, and toddlers’ RSA was assessed at baseline and during 5 moderately challenging tasks. Groups did not differ in baseline RSA, but differed in RSA reactivity to the tasks. Across tasks, toddlers of parents in the control condition manifested significantly larger RSA decreases than toddlers of parents in the PFR condition. Parental behavior showed divergent associations with RSA change for toddlers of parents in the PFR versus control condition, with PFR treatment predicting RSA change ranging from small decreases to increases in toddlers of parents who showed the most sensitive, responsive behavior in the 6 months following treatment. This preliminary study showed that the same intervention that improved parenting also improved toddlers’ parasympathetic regulation in response to everyday activities, warranting further experimental investigation.
