We investigated circadian mother-child adrenocortical attunement in the context of a maternal history of childhood abuse (HoA). Mothers were screened after birth using the Childhood Trauma Questionnaire. Women reporting moderate or severe abuse formed the HoA group (n = 37; HoAG) and were compared with a non-maltreated comparison group (n = 45; CG). Three years later, cortisol awakening response (CAR) and diurnal slope (DSL) were assessed. Mother-child interaction was coded using the Emotional Availability Scales at 12 months of age. For the CAR, we found adrenocortical attunement only in the HoAG (2-way interaction: p = .004), particularly if mothers scored low on structuring (3-way interaction: p = .042) and children scored low on responsiveness (3-way interaction: p = .044). DSL-attunement was dependent on maternal sensitivity (3-way interaction: p = .012) and child involvement (3-way interaction: p = .012). In the context of a maternal HoA, it seems possible for mother-child-dyads to show less optimal interactional quality but be stronger attuned to each other biologically.
我们在有童年虐待史（HoA）的母亲背景下，研究了昼夜节律的母婴肾上腺皮质协调情况。母亲在产后使用儿童创伤问卷进行筛查。报告有中度或重度虐待的女性组成HoA组（n = 37；HoAG），并与未受虐待的对照组（n = 45；CG）进行比较。三年后，评估皮质醇觉醒反应（CAR）和昼夜斜率（DSL）。在孩子12个月大时，使用情感可及性量表对母婴互动进行编码。对于CAR，我们仅在HoAG组中发现了肾上腺皮质协调（双向交互作用：p = 0.004），特别是当母亲在结构化方面得分较低时（三向交互作用：p = 0.042）以及孩子在反应性方面得分较低时（三向交互作用：p = 0.044）。DSL协调取决于母亲的敏感性（三向交互作用：p = 0.012）和孩子的参与度（三向交互作用：p = 0.012）。在有母亲HoA的背景下，母婴二元组似乎有可能表现出不太理想的互动质量，但在生物学上彼此的协调性更强。
