Difficulties in emotion regulation are associated with development and maintenance of psychopathology. Typically, features of emotion regulation are assessed with self-report questionnaires. Heart rate variability (HRV) is an objective measure proposed as an index of emotional regulation capacity. A limited number of studies have shown that self-reported difficulties in emotion regulation are associated with HRV. However, results from prior studies are inconclusive, and an ecological validation of the association has not yet been tested. Therefore, further exploration of the relation between self-report questionnaires and psychophysiological measures of emotional regulation is needed. The present study investigated the contribution of self-reported emotion regulation difficulties on HRV in a student sample. We expected higher scores on emotion regulation difficulties to be associated with lower vagus-mediated HRV (vmHRV). Sixty-three participants filled out the Difficulties in Emotion Regulation Scale and their resting HRV was assessed. In addition, a subsample of participants provided ambulatory 24-h HRV data, in order to ecologically validate the resting data. Correlation analyses indicated that self-reported difficulties in emotion regulation was negatively associated with vmHRV in both resting HRV and 24-h HRV. Specifically, when exploring the contribution of the different facets of emotion dysregulation, the inability to accept negative emotions showed the strongest association with HRV. The results are discussed and need for future research is described.
情绪调节困难与精神病理学的发展和维持相关。通常，情绪调节的特征通过自我报告问卷进行评估。心率变异性（HRV）是一种被提议作为情绪调节能力指标的客观测量方法。少数研究表明，自我报告的情绪调节困难与HRV相关。然而，先前研究的结果并不确定，且该关联的生态学验证尚未得到检验。因此，需要进一步探索自我报告问卷与情绪调节的心理生理测量之间的关系。本研究调查了学生样本中自我报告的情绪调节困难对HRV的影响。我们预期情绪调节困难得分越高，与迷走神经介导的HRV（vmHRV）越低相关。63名参与者填写了情绪调节困难量表，并评估了他们的静息HRV。此外，部分参与者提供了24小时动态HRV数据，以便对静息数据进行生态学验证。相关分析表明，自我报告的情绪调节困难在静息HRV和24小时HRV中均与vmHRV呈负相关。具体而言，在探究情绪失调不同方面的影响时，无法接受负面情绪与HRV的关联最为强烈。对研究结果进行了讨论，并描述了未来研究的必要性。
