Effects of HRV Biofeedback, Interoceptive Training, and Mindfulness on Stress in University Students and Staff

This mindfulness training program is based on the Mindfulness-Based Stress Reduction (MBSR) model developed by Jon Kabat-Zinn, incorporating elements of self-compassion and acceptance. What sets this program apart is its integration of both formal and informal practices. Participants engage in 45-minute guided sessions focused on breath awareness and the observation of thoughts, emotions, and physical sensations. Additionally, informal practices include brief daily moments of present-moment awareness. Participants will also receive 10 audio recordings for at-home practice, enhancing the program's accessibility and supporting consistency.

This HRV biofeedback training program is distinguished by its combination of advanced technology and a novel at-home methodology. Participants will engage in five weekly sessions, with four conducted at home using a heart rate sensor and the EliteHRV mobile app, which provides real-time feedback on heart rate variability. One session per week will take place in the lab, utilizing the Procomp Infiniti biofeedback system. The at-home approach is based on recent research (Schumann et al., 2021), offering participants a flexible yet structured method to practice biofeedback and improve heart rate variability over the six-week program.

The interoception training program stands out by its focus on developing internal body awareness through structured guided sessions. Participants will engage in weekly 45-minute formal sessions at the university, where they will learn to focus on internal sensations like breath and muscle tension using specific techniques. Additionally, participants will receive 10 guided interoceptive exercises to practice at home, four times a week. This program not only focuses on the physical sensations but also integrates these practices into daily life, aiming to improve self-care and self-regulation over the six weeks, with personalized feedback provided.
