Abstract：
UNASSIGNED: Heart rate variability biofeedback (HRVB) is a well-studied intervention known for its positive effects on emotional, cognitive, and physiological well-being, including relief from depressive symptoms. However, its practical use is hampered by high costs and a lack of trained professionals. Smartphone-based HRVB, which eliminates the need for external devices, offers a promising alternative, albeit with limited research. Additionally, premenstrual symptoms are highly prevalent among menstruating individuals, and there is a need for low-cost, accessible interventions with minimal side effects. With this pilot study, we aim to test, for the first time, the influence of smartphone-based HRVB on depressive and premenstrual symptoms, as well as anxiety/stress symptoms and attentional control.
UNASSIGNED: Twenty-seven participants with above-average premenstrual or depressive symptoms underwent a 4-week photoplethysmography smartphone-based HRVB intervention using a waitlist-control design. Laboratory sessions were conducted before and after the intervention, spaced exactly 4 weeks apart. Assessments included resting vagally mediated heart rate variability (vmHRV), attentional control via the revised attention network test (ANT-R), depressive symptoms assessed with the BDI-II questionnaire, and stress/anxiety symptoms measured using the DASS questionnaire. Premenstrual symptomatology was recorded through the PAF questionnaire if applicable. Data analysis employed linear mixed models.
UNASSIGNED: We observed improvements in premenstrual, depressive, and anxiety/stress symptoms, as well as the Executive Functioning Score of the ANT-R during the intervention period but not during the waitlist phase. However, we did not find significant changes in vmHRV or the Orienting Score of the ANT-R.
UNASSIGNED: These findings are promising, both in terms of the effectiveness of smartphone-based HRVB and its potential to alleviate premenstrual symptoms. Nevertheless, to provide a solid recommendation regarding the use of HRVB for improving premenstrual symptoms, further research with a larger sample size is needed to replicate these effects.

摘要：
■心率变异性生物反馈（HRVB）是一种经过充分研究的干预措施，以其对情绪的积极影响而闻名。认知，和生理健康，包括缓解抑郁症状.然而,它的实际使用受到高成本和缺乏训练有素的专业人员的阻碍。基于智能手机的HRVB，这消除了对外部设备的需求，提供了一个有希望的替代方案，尽管研究有限。此外,经前症状在经期个体中非常普遍，需要低成本，可获得的干预措施，副作用最小。通过这项试点研究，我们的目标是测试，第一次,基于智能手机的HRVB对抑郁和经前症状的影响，以及焦虑/压力症状和注意力控制。
27名具有高于平均水平的经前或抑郁症状的参与者使用等待列表控制设计进行了为期4周的基于智能手机的光电体积描记术HRVB干预。在干预前后进行了实验室会议，相隔4周。评估包括静息性迷走神经介导的心率变异性（vmHRV），通过修订的注意力网络测试(ANT-R)进行注意力控制，用BDI-II问卷评估抑郁症状，和使用DASS问卷测量的压力/焦虑症状。如果适用，通过PAF问卷记录经前症状。数据分析采用线性混合模型。
■我们观察到经前的改善，抑郁,和焦虑/压力症状，以及ANT-R在干预期间的执行功能评分，而不是在等待列表阶段。然而,我们没有发现vmHRV或ANT-R的定向评分有明显变化。
■这些发现很有希望，无论是基于智能手机的HRVB的有效性还是其缓解经前症状的潜力。然而，提供关于使用HRVB改善经前症状的可靠建议，需要更大样本量的进一步研究来复制这些效应.
