Background and study aims
Stress is common and has negative effects on mental and physical health. This study aims to use a stress management method called heart rate variability biofeedback to reduce levels of stress in healthy adults. During a heart rate variability biofeedback training participants learn to control the activity of their heart. In order to teach participants, virtual reality technology is used to visualize changes in the heart’s activity in an engaging way. Practising this for a longer period of time can reduce stress levels and improve other stress-related symptoms such as anxiety or depression.

Who can participate?
Healthy volunteers aged 18-40 years

What does the study involve?
Participants are randomly allocated to one of two groups. Participants doing the heart rate variability biofeedback training will be compared to participants in a wait-list control group, which will receive the training only after the assessments. Both groups will be compared at three timepoints: before the training, 1 week after the training and 4 weeks after the training. During these assessments, the researchers measure the psychological and biological effects of the training.

What are the possible benefits and risks of participating?
Comparable studies show that several weeks of heart rate variability biofeedback training reduce stress significantly. This includes reducing perceived stress, anxiety, and depression, as well as improving quality of life and well-being. The training can also improve participants’ heart activity. Even if randomly assigned to the waitlist, participants have the option to do the training after the study to benefit from its effects. There are no direct disadvantages to participating, and there are no serious health risks. During the training short-term hyperventilation may occur, leading to dizziness and lightheadedness. Additionally, the use of virtual reality technology may temporarily cause a condition known as cybersickness, which includes symptoms such as eye strain, headaches, paleness, sweating, dry mouth, fullness, disorientation, dizziness, impaired coordination, nausea, and vomiting. However, these potential side effects of the training and virtual reality technology are rare and harmless.

Scientific titleEvaluating the psychobiological effectiveness and user experience of virtual reality heart rate variability biofeedback intervention programme for stress management in healthy individuals: a randomized wait-list control trial
Study objectivesThe virtual reality-supported heart rate variability biofeedback intervention programme will improve primary and secondary outcomes (i.e., stress and stress-related measures) from pre-intervention to post-intervention and from pre-intervention to follow-up compared to the wait-list control group.
Ethics approval(s)Approved 15/03/2022, Ethics Commission of ETH Zurich (ETH Zürich, Stab Forschung, Weinbergstrasse 11, WEC E 15/17, 8092 Zürich, Switzerland; +41 (0)44 632 85 72; ethics@sl.ethz.ch), ref: 2022-N-35
Health condition(s) or problem(s) studiedReduction of stress and stress-related symptoms in healthy individuals
InterventionThe 4-week intervention programme investigated in this study includes four training sessions of heart rate variability biofeedback in virtual reality conducted weekly in the laboratory, which are supplemented by brief daily at-home exercises supported by a mobile application. The study also includes a wait-list control group. Participants (50% male and 50% female) will be randomly assigned to either the intervention group or the wait-list control group, which will both simultaneously undergo three assessments (pre-assessment during week 1 of the intervention, post-assessment in the week after the intervention and follow-up-assessment 4 weeks after the intervention). Randomisation takes place when participants sign up for their sessions. Experimenters have already pre-assigned groups to a specific day and time. Participants will only be informed about their group assignment after they have signed up.

Randomisation was achieved by hidden pre-assigned groups (intervention or wail-list control) for each session participants could sign up for. Specifically, participants were able to select one of ten possible first sessions (i.e. in the first week), without knowing the hidden pre-assigned group of each sessions. Only after signing up for the study were the participants informed about the assigned group.
Intervention typeBehavioural
