Abstract

Resting heart rate variability (HRV) is typically higher in those with better emotional well-being. In the current study, we examined whether changes in resting HRV mediated changes in negative emotions during a 7-week clinical trial of HRV biofeedback. Younger and older adults were randomly assigned to one of two daily biofeedback practices for 5 weeks: (1) engage in slow-paced breathing to increase the amplitude of oscillations in heart rate at their breathing frequency (Osc+); or (2) engage in self-selected strategies to decrease heart rate oscillations (Osc-). We assessed negative emotion using the State Anxiety Inventory (SAI) and Profile of Mood States (POMS). Resting HRV at pre-intervention was significantly higher among those with lower negative emotion scores. Those participants showing greater increases in resting HRV showed greater decreases in negative emotion. In a mediation model with all participants, resting HRV changes significantly mediated the relationship between training performance (i.e., heart rate oscillation during practice sessions) and changes in negative emotion. However, additional analyses revealed this mediation effect was significantly moderated by condition and was only significant in the Osc+ condition. Thus, resting HRV changes mediated how biofeedback to increase amplitude of heart rate oscillations reduced negative emotion.

在为期五周的心率变异生物反馈干预中，消极情绪的变化受静息心率变异性变化的调节。

情绪较好的人静息心率变异性（HRV）通常较高。在当前的研究中，我们研究了在为期 7 周的心率变异生物反馈临床试验中，静息心率变异的变化是否介导了负面情绪的变化。年轻和年长的成年人被随机分配到两种每日生物反馈练习中的一种，为期 5 周：（1）进行慢节奏呼吸，以增加呼吸频率下的心率振荡幅度（Osc+）；或（2）进行自我选择策略，以减少心率振荡（Osc-）。我们使用状态焦虑量表（SAI）和情绪状态档案（POMS）评估负面情绪。在干预前，消极情绪得分较低者的静息心率变异显著较高。静息心率变异增加较多的参与者消极情绪减少较多。在所有参与者的调解模型中，静息心率变异显著调解了训练表现（即练习过程中的心率振荡）与消极情绪变化之间的关系。然而，额外的分析表明，这种中介效应受到条件的显著调节，只有在 Osc+ 条件下才显著。因此，静息心率变异对生物反馈如何增加心率振荡幅度以减少负面情绪起着中介作用。

期刊介绍： Applied Psychophysiology and Biofeedback is an international, interdisciplinary journal devoted to study of the interrelationship of physiological systems, cognition, social and environmental parameters, and health. Priority is given to original research, basic and applied, which contributes to the theory, practice, and evaluation of applied psychophysiology and biofeedback. Submissions are also welcomed for consideration in several additional sections that appear in the journal. They consist of conceptual and theoretical articles; evaluative reviews; the Clinical Forum, which includes separate categories for innovative case studies, clinical replication series, extended treatment protocols, and clinical notes and observations; the Discussion Forum, which includes a series of papers centered around a topic of importance to the field; Innovations in Instrumentation; Letters to the Editor, commenting on issues raised in articles previously published in the journal; and select book reviews. Applied Psychophysiology and Biofeedback is the official publication of the Association for Applied Psychophysiology and Biofeedback.
