内化和外化疾病通常与呼吸性窦性心律失常 (RSA) 的低基线水平相关，尽管在幼儿研究中不一致。因此，RSA 被认为反映了灵活和调节情感反应的能力以及精神病理学的一般倾向。然而，评估 RSA 对情绪挑战反应性的研究倾向于报告与内化障碍的关联性比与外化障碍的关联性更一致，尽管尚不清楚这是否与所使用的情绪挑战类型有关。在本研究中，我们以 273 名患有精神病理学症状的幼儿（5-6 岁）为样本，检查了基线 RSA 是否与内化和/或外化严重程度相关。根据基于动机的情绪模型，我们还测试了基于退缩（恐惧、悲伤）和基于接近（快乐、愤怒）的情绪诱导期间 RSA 反应是否分别与内化和外化症状存在差异相关。基线 RSA 与外化或内化症状的严重程度无关。然而，RSA 对特定情绪挑战的反应与每个症状领域有不同的相关性。正如预期的那样，在恐惧和悲伤的电影片段中，内化症状的严重程度与更大的 RSA 撤退（唤醒增加）相关。相反，外化症状的严重程度与观看快乐电影片段时 RSA 的减弱有关。使用理论上衍生的刺激可能对于表征情感处理缺陷的性质很重要，这些缺陷区分了精神病理学的内化和外化领域。
Internalizing and externalizing disorders are often, though inconsistently in studies of young children, associated with low baseline levels of respiratory sinus arrhythmia (RSA). RSA is thus considered to reflect the capacity for flexible and regulated affective reactivity and a general propensity for psychopathology. However, studies assessing RSA reactivity to emotional challenges tend to report more consistent associations with internalizing than with externalizing disorders, although it is unclear whether this is a function of the type of emotion challenges used. In the present study, we examined whether baseline RSA was associated with internalizing and/or externalizing severity in a sample of 273 young children (ages 5–6) with elevated symptoms of psychopathology. Following motivation-based models of emotion, we also tested whether RSA reactivity during withdrawal-based (fear, sadness) and approach-based (happiness, anger) emotion inductions was differentially associated with internalizing and externalizing symptoms, respectively. Baseline RSA was not associated with externalizing or internalizing symptom severity. However, RSA reactivity to specific emotional challenges was associated differentially with each symptom domain. As expected, internalizing symptom severity was associated with greater RSA withdrawal (increased arousal) during fearful and sad film segments. Conversely, externalizing symptom severity was related to blunted RSA withdrawal during a happy film segment. The use of theoretically derived stimuli may be important in characterizing the nature of the deficits in emotion processing that differentiate the internalizing and externalizing domains of psychopathology.
