本文对125对父婴和141对母婴进行了陌生情境程序（SSP）中的父婴和母婴（1奥尔兹）肾上腺皮质协调的研究。在基线（T1）、第一次亲子分离后20分钟（T2）和40分钟（T3）评估皮质醇。初始相关性表明，父亲-婴儿和母亲-婴儿皮质醇之间的显着关联在每个时间。皮质醇的相互依赖性进一步探讨使用演员-合作伙伴相互依赖模型。一旦稳定性和交叉滞后路径得到控制，没有证据支持基于亲子皮质醇之间的时间内残余相关性的皮质醇相互依赖性。婴儿皮质醇在T2预测T3皮质醇的父亲和母亲导致一系列后续的探索性分析，以检查中介过程中发现，婴儿痛苦在SSP预测婴儿T2皮质醇，这反过来又预测婴儿消极在15分钟的母婴教学任务，随后SSP。在父亲-婴儿二人组中，婴儿T2皮质醇预测婴儿在父亲-婴儿互动过程中的消极性，婴儿表达更多的消极性，父亲不太敏感。研究结果提供了一点支持的父母-婴儿肾上腺皮质协调无论是父亲-婴儿或母亲-婴儿的二对在SSP，但初步证据表明，婴儿的痛苦作为一个潜在的调解。未来的研究可能会集中在情感和行为过程的基础上的概念，父母-婴儿肾上腺皮质协调。
Father-infant and mother-infant (one-year-olds) adrenocortical attunement was explored during the Strange Situation Procedure (SSP) among 125 father-infant and 141 mother-infant dyads. Cortisol was assessed at baseline (T1), 20 (T2) and 40 minutes (T3) after the first parent-infant separation. Initial correlations indicated significant associations between father-infant and mother-infant cortisol at each time. Cortisol interdependence was further explored using Actor-Partner Interdependence Models. There was no evidence supporting cortisol interdependence based on within-time residual correlations between parent-infant cortisol, once stability and cross-lagged paths were controlled. Infant cortisol at T2 predicted T3 cortisol for fathers and mothers resulting in a series of follow-up exploratory analyses to examine mediating processes which revealed that infant distress during the SSP predicted infant T2 cortisol, which, in turn, predicted infant negativity during the 15-minute mother-infant teaching task that followed the SSP. Among father-infant dyads, infant T2 cortisol predicted infant negativity during father-infant interaction, with infants expressing more negativity having less sensitive fathers. Findings provide little support of parent-infant adrenocortical attunement across either father-infant or mother-infant dyads during the SSP, but preliminary evidence indicates infant distress as a potential mediator. Future research may want to focus on affective and behavioral processes that underlie the concept of parent-infant adrenocortical attunement.
