While emotionality is often thought of as a risk factor, differential susceptibility theory argues that emotionality reflects susceptibility to both positive and negative environmental influences. The present study explored whether emotional children might be more susceptible to the effects of both high and low maternal responsiveness on allostatic load, a physiological indicator of chronic stress. Participants were 226 mother and child dyads. Mothers reported on children's emotionality at child age 9. Maternal responsiveness was measured at age 13 using self-reports and behavioral observation. Allostatic load was measured at age 13 and 17 using neuroendocrine, cardiovascular, and metabolic biomarkers. Emotionality was associated with higher allostatic load if self-reported responsiveness was low, but with lower allostatic load, when self-reported responsiveness was high.
虽然情绪通常被认为是一个风险因素，但差异易感性理论认为，情绪反映了对积极和消极环境影响的易感性。本研究探讨了情绪儿童是否更容易受到高和低的母亲反应性对所有压力的影响，这是慢性应激的生理指标。参与者是 226 对母婴对子。母亲在孩子 9 岁时报告孩子的情绪。在 13 岁时，使用自我报告和行为观察来测量母亲的反应能力。在 13 岁和 17 岁时，使用神经内分泌、心血管和代谢生物标志物来测量所有压力的负荷。如果自我报告的反应性较低，情绪与更高的所有压力负荷有关，但如果自我报告的反应性较高，则与较低的所有压力负荷有关。
