We examined indices of vagal tone and two dimensions of temperament as predictors of emotion regulation (ER) strategies among children (n = 54, ages 4-7) of mothers with a history of depression and control mothers. Children's (adaptive and maladaptive) ER strategies were observed during a delay of gratification (frustration) task in one protocol. In a separate and independent protocol, vagal tone was assessed during rest (baseline), during emotional challenge (reactivity) and post-challenge (recovery) and mothers rated their children's temperament (effortful control, negative affectivity). Lower vagal recovery and higher negative affectivity were associated with maladaptive ER responses to frustration. However, vagal tone and temperament were not associated with adaptive ER responses and maternal depression status did not affect the results. Overall, the findings are consistent with models of vagal tone and temperament as markers of individual differences in ER.
我们研究了迷走神经张力指标和气质的两个维度，以此作为有抑郁病史母亲的孩子（n = 54，4至7岁）及对照母亲的孩子情绪调节（ER）策略的预测指标。在一个方案中，通过延迟满足（挫折）任务观察了儿童（适应性和适应不良性）的ER策略。在另一个独立方案中，在静息状态（基线）、情绪挑战（反应性）期间和挑战后（恢复）评估迷走神经张力，母亲对孩子的气质（努力控制、消极情感）进行评分。较低的迷走神经恢复和较高的消极情感与对挫折的适应不良性ER反应相关。然而，迷走神经张力和气质与适应性ER反应无关，且母亲的抑郁状态不影响结果。总体而言，研究结果与迷走神经张力和气质作为ER个体差异标志物的模型一致。
