Self-reports and physiological indicators of stress such as cortisol levels are correlated in maternal and child samples. This relationship is likely to be influenced by maternal emotion regulation. Herein, we investigate the moderating role of maternal regulation strategies on the association between maternal and child hair cortisol levels. Mother-child dyads (N = 63, child mean age = 49.74 months) participated in the study. Hair samples were collected from mother and child, and cortisol was assayed. Mothers reported on their own emotion regulation strategies, namely expressive suppression and cognitive reappraisal. As expected, mother and child hair cortisol levels were significantly correlated. Interestingly, the relation between maternal and child hair cortisol was moderated by maternal suppression of emotion. Mother and child hair cortisol levels were related at low levels of maternal suppression, but not at higher levels of suppression. Maternal cognitive reappraisal of emotion was not associated with cortisol levels.
在母婴样本中，压力的自我报告和生理指标（如皮质醇水平）是相关的。这种关系可能会受到母亲情绪调节的影响。在此，我们研究母亲调节策略对母婴头发皮质醇水平之间关联的调节作用。母婴二元组（N = 63，儿童平均年龄 = 49.74个月）参与了该研究。采集了母亲和孩子的头发样本，并检测了皮质醇。母亲报告了她们自己的情绪调节策略，即表达抑制和认知重评。正如预期的那样，母婴头发皮质醇水平显著相关。有趣的是，母婴头发皮质醇之间的关系受到母亲情绪抑制的调节。在母亲低水平的抑制下，母婴头发皮质醇水平相关，但在高水平抑制下则不相关。母亲对情绪的认知重评与皮质醇水平无关。
