This was a three-arm, non-randomized, controlled trial to examine the effects of a preventative, 4-week resilience training with mobile HRV-BfB on work-related stress in white-collar employees. Participants were asked to exercise autonomously three times per day for five minutes with the mobile HRV-BfB device. They additionally attended three lectures at the beginning of the first, third, and forth week. The aim of the lectures was to mediate a theoretical knowledge and to prepare the participants for the autonomous training. To examine the potential influence of the lecture format, one group attended live lectures (blended learning condition) and one group received access to online lectures (e-learning condition). Results of study's outcome measures were compared with a waitlist control group. Outcome measures were assessed at baseline (T0), after the 4-week intervention (T1), and at 4-week follow-up (T2).
A study to analyze the psychophysiological effects of a preventative, 4-week resilience training with mobile heart rate variability biofeedback (HRV-BfB) in a workplace setting and the influence of the lecture format (digital vs. live) on the training success.
