The present study used a longitudinal randomized clinical trial to test whether an early intervention has causal effects on children's autonomic nervous system regulation. When children were infants, parents involved with Child Protective Services received Attachment and Biobehavioral Catch-up (ABC; N = 43), an intervention that promotes sensitive parenting, or a control intervention (N = 53). When children were 9 years old, children whose parents had received ABC exhibited higher respiratory sinus arrhythmia and lower heart rate at rest and during a parent-child interaction than children in the control group. Intervention effects were not detected for children's average skin conductance levels or for indices of autonomic reactivity. Results suggest that a parenting-focused early intervention impacted the development of children's autonomic regulation.
本研究采用纵向随机临床试验，以检验早期干预对儿童自主神经系统调节是否具有因果效应。当儿童尚为婴儿时，涉及儿童保护服务的父母接受了促进敏感育儿的干预措施“依恋与生物行为追赶”（ABC；N = 43），或接受对照干预（N = 53）。当儿童9岁时，与对照组儿童相比，父母接受过ABC干预的儿童在静息状态及亲子互动期间表现出更高的呼吸性窦性心律不齐和更低的心率。未检测到该干预对儿童平均皮肤电导水平或自主反应性指标的影响。结果表明，以育儿为重点的早期干预影响了儿童自主调节的发展。
