学龄前儿童的家庭参加了两个二元家庭访问，一次与母亲（56对），一次与父亲（59对）。二分体的每个成员提供了三个皮质醇样本，并参与了几个互动任务，行为编码。大约一半的儿童被诊断患有自闭症谱系障碍（ASD），而另一半则是典型的发展（TD）。在多水平模型中，父亲的皮质醇水平在每个时间点预测儿童皮质醇。父亲与孩子的联系在互惠性较低的二人组中更强，父亲表现出较低的敏感性，而孩子表现出较低的自我调节和更多的退缩。皮质醇水平在母子二人组中没有显著相关性，并且通过ASD诊断有适度的趋势，这样TD儿童的联系更大。母子联系在表现出较少的行为协调性和敏感性的二人组中更强。HPA轴联动可能是较强的行为协调的二对。
Families of preschoolers participated in two dyadic home visits, once with mother (56 dyads) and once with father (59 dyads). Each member of the dyad provided three cortisol samples and participated in several interaction tasks that were behaviorally coded. Approximately half of the children had been diagnosed with autism spectrum disorders (ASD), whereas half were typically developing (TD). In a multilevel model, father's cortisol level at each timepoint predicted child cortisol. Father-child linkage was stronger in dyads that showed less reciprocity, in which fathers showed less sensitivity, and in which children showed less self-regulation and more withdrawal. Cortisol levels were not significantly correlated in mother-child dyads, and there was a trend toward moderation by ASD diagnosis, such that linkage was greater in TD children. Mother-child linkage was stronger in dyads that showed less behavioral coordination and less sensitivity. HPA axis linkage may be stronger in less behaviorally attuned dyads.
