Abstract

Heart rate variability (HRV) is an index of cardiac autonomic function and an objective biomarker for stress and health. Improving HRV through biofeedback has proven effective in reducing symptoms of posttraumatic stress disorder (PTSD) and depression in veteran populations. Brief protocols involving fewer sessions can better maximize limited clinic resources; however, there is a dearth of knowledge on the number of clinical sessions needed to significantly reduce trauma and depression symptoms. We conducted a series of linear regression models using baseline, post-intervention, and follow-up data from intervention group participants (N = 18) who engaged in a pilot waitlist-controlled study testing the efficacy of a 3-session mobile app-adapted HRV biofeedback intervention for veterans with PTSD. Based on Nunan et al. (Pacing and Clinical Electrophysiology 33:1407–1417, 2010) short-term norms, we found that pre-intervention RMSSD in the normal range significantly predicted PTSD and depression symptom improvement. Findings suggest the utility of baseline RMSSD as a useful metric for predicting HRV biofeedback treatment outcomes for veterans with PTSD and comorbid depression. Those with below-normal baseline RMSSD may likely need additional sessions or an alternative treatment to show clinically meaningful symptom improvement.

简要报告：基线心率变异时域参数可预测接受生物反馈治疗的创伤后应激障碍退伍军人的创伤和抑郁症状变化。

心率变异性（HRV）是心脏自律神经功能的指标，也是压力和健康的客观生物标志物。事实证明，通过生物反馈改善心率变异能有效减轻退伍军人的创伤后应激障碍（PTSD）和抑郁症状。涉及较少疗程的简短方案可以更好地最大限度地利用有限的诊所资源；然而，对于显著减轻创伤和抑郁症状所需的临床疗程数量，我们还缺乏足够的了解。我们使用干预组参与者（18 人）的基线、干预后和随访数据建立了一系列线性回归模型，这些参与者参与了一项试验性候补名单对照研究，该研究测试了针对创伤后应激障碍退伍军人的 3 个疗程的移动应用程序心率变异生物反馈干预的效果。根据 Nunan 等人（《起搏与临床电生理学》33:1407-1417，2010 年）的短期标准，我们发现干预前 RMSSD 在正常范围内可显著预测创伤后应激障碍和抑郁症状的改善。研究结果表明，基线 RMSSD 是预测患有创伤后应激障碍和合并抑郁症的退伍军人心率变异生物反馈治疗效果的有用指标。基线 RMSSD 低于正常值的退伍军人可能需要额外的疗程或其他治疗方法才能显示出有临床意义的症状改善。

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.
