非稳态负荷理论假设压力和身体对压力源的反应会随着时间的推移导致多个系统的长期生理变化（非稳态），并且这些系统功能的变化对调整和健康有影响。我们调查了这些假设的纵向数据从两个独立的样本（n = 413，219名女孩，194名男孩）在8岁，9岁，10岁和11岁的重复测量。最初的父母的婚姻冲突及其随时间的变化索引儿童暴露于一个重要的家庭压力源，这是在相互作用与儿童的呼吸性窦性心律失常（RSA）反应实验室任务（压力反应）预测儿童的基础水平的RSA随着时间的推移进行了检查。我们还调查了儿童性别作为额外可能的调节因素。我们的第二个研究问题集中在检查是否初始水平和变化，在休息RSA随着时间的推移预测儿童的外化行为。一个强大的RSA抑制反应，一个令人沮丧的实验室任务的男孩经历了更高的初始婚姻冲突或随着时间的推移增加婚姻冲突显示，随着时间的推移，他们的休息RSA下降。此外，男孩的初始静息RSA（但不是静息RSA随时间的变化）与外化症状随时间的变化呈负相关。对女孩的调查结果更为复杂。结果进行了讨论的背景下，发展心理生物学，allostatic负荷，精神病理学的发展和影响。
Allostatic load theory hypothesizes that stress and the body’s responses to stressors contribute to longer term physiological changes in multiple systems over time (allostasis), and that shifts in how these systems function have implications for adjustment and health. We investigated these hypotheses with longitudinal data from two independent samples (n = 413; 219 girls, 194 boys) with repeated measures at ages 8, 9, 10, and 11. Initial parental marital conflict and its change over time indexed children’s exposure to an important familial stressor, which was examined in interaction with children’s respiratory sinus arrhythmia (RSA) reactivity to laboratory tasks (stress response) to predict children’s basal levels of RSA over time. We also investigated children’s sex as an additional possible moderator. Our second research question focused on examining whether initial levels and changes in resting RSA over time predicted children’s externalizing behavior. Boys with a strong RSA suppression response to a frustrating laboratory task who experienced higher initial marital conflict or increasing marital conflict over time showed decreases in their resting RSA over time. In addition, boys’ initial resting RSA (but not changes in resting RSA over time) was negatively related to change over time in externalizing symptoms. Findings for girls were more mixed. Results are discussed in the context of developmental psychobiology, allostatic load, and implications for the development of psychopathology.
