Study Details
Study Description

Detailed Description
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).

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Resilience training with mobile HRV-BfB based on an e-learning approach (with digital lectures)
|
Other: Resilience training with mobile HRV-BfB based on an e-learning approach (with digital lectures)
A 4-week resilience training with a mobile HRV-BfB device. Participants received access to three online lectures at the start of the first, third, and forth training week (each lasting 60 minutes) to receive a theoretical base on resilience and to learn how to exercise with the HRV-BfB device. Participants were asked to exercise three times a day for 5 minutes in their occupational and leisure time with the HRV-BfB device.

A 4-week resilience training with a mobile HRV-BfB device. Participants attended three live lectures at the start of the first, third, and forth training week (each lasting 90 minutes) to receive a theoretical base on resilience and to learn how to exercise with the HRV-BfB device. Participants were asked to exercise three times a day for 5 minutes in their occupational and leisure time with the HRV-BfB device.

Outcome Measures
Primary Outcome Measures
- COPSOQ personal burnout after the intervention [After the 4-week intervention (T1)]
Personal burnout was assessed with the adapted German long version of the Copenhagen Psychosocial Questionnaire (COPSOQ) at T1. Six questions were answered on an ordinal scale, transformed to values ranging between 0=minimum value and 100=maximum value (higher values indicate a more severe burnout symptomatology) and averaged to obtain a scale score (0-100).
Secondary Outcome Measures
- Change in the COPSOQ scale personal burnout between baseline (T0) and 4-week follow-up (T2) [Baseline (T0) and 4-week follow-up (T2)]
Personal burnout was assessed with the adapted German long version of the Copenhagen Psychosocial Questionnaire (COPSOQ) at T0 and T2. Six questions were answered on an ordinal scale, transformed to values ranging between 0=minimum value and 100=maximum value (higher values indicate a more severe burnout symptomatology) and averaged to obtain a scale score (0-100).
- Change in the COPSOQ scale subjective general health between baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2) [Baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2)]
The subjective general health was assessed with the adapted German long version of the Copenhagen Psychosocial Questionnaire (COPSOQ, originally derived from the EQ-5D) at T0, T1, and T2 (single question). The question was transformed to a scale ranging from 0=minimum value to 100=maximum value (lower values indicate a worse general health).
- Change in the COPSOQ scale work-privacy conflict between baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2) [Baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2)]
Work-privacy conflict was assessed with the adapted German long version of the Copenhagen Psychosocial Questionnaire (COPSOQ) at T0 and T2. Five questions were answered on an ordinal scale, transformed to values ranging between 0=minimum value and 100=maximum value (higher values indicate a worse conflict) and averaged to obtain a scale score (0-100).
- Change in the COPSOQ scale behavioral stress symptoms between baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2) [Baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2)]
Behavioral stress symptoms were assessed with the adapted German long version of the Copenhagen Psychosocial Questionnaire (COPSOQ) at T0 and T2. Eight questions were answered on an ordinal scale, transformed to values ranging between 0=minimum value and 100=maximum value (higher values indicate more severe stress symptoms) and averaged to obtain a scale score (0-100).
- Change in the COPSOQ scale cognitive stress symptoms between baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2) [Baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2)]
Cognitive stress symptoms were assessed with the adapted German long version of the Copenhagen Psychosocial Questionnaire (COPSOQ) at T0 and T2. Four questions were answered on an ordinal scale, transformed to values ranging between 0=minimum value and 100=maximum value (higher values indicate more severe stress symptoms) and averaged to obtain a scale score (0-100).
- Change in self-reported sleep quality between baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2) [Baseline (T0), after the 4-week intervention (T1), and 4-week follow-up (T2)]
Self-reported sleep quality, latency, and sleep duration were assessed with the Pittsburgh Sleep Quality Index (PSQI) at T0, T1, and T2. Items were averaged to obtain values between 0 and 3 (higher values indicate a poorer sleep).
- HRV analysis: Change in SDNN between baseline (T0) and after the 4-week intervention (T1) [Baseline (T0) and after the 4-week intervention (T1)]
Standard deviation of normal to normal (NN) intervals (ms). Recorded with the software InnerBalanceTM Trainer (HeartMath Deutschland GmbH, Germany) and analyzed with the software HRV-Scanner (BioSign GmbH, Germany).
- HRV analysis: Change in RMSSD between baseline (T0) and after the 4-week intervention (T1) [Root mean square of successive differences (ms). Recorded with the software InnerBalanceTM Trainer (HeartMath Deutschland GmbH, Germany) and analyzed with the software HRV-Scanner (BioSign GmbH, Germany).]
Baseline (T0) and after the 4-week intervention (T1)
- HRV analysis: Change in pNN50 between baseline (T0) and after the 4-week intervention (T1) [Baseline (T0) and after the 4-week intervention (T1)]
Percentage of successive NN intervals that differ from each other by more than 50 ms (%). Recorded with the software InnerBalanceTM Trainer (HeartMath Deutschland GmbH, Germany) and analyzed with the software HRV-Scanner (BioSign GmbH, Germany).
- HRV analysis: Change in Baevsky's stress index between baseline (T0) and after the 4-week intervention (T1) [Baseline (T0) and after the 4-week intervention (T1)]
Baevsky's stress index is computed from the main characteristics of the inter-beat intervals histogram (mode value, mode amplitude, and variation range). Recorded with the software InnerBalanceTM Trainer (HeartMath Deutschland GmbH, Germany) and analyzed with the software HRV-Scanner (BioSign GmbH, Germany).
- HRV analysis: Change in the degree of rhythmization between baseline (T0) and after the 4-week intervention (T1) [Baseline (T0) and after the 4-week intervention (T1)]
A measure that quantifies the respiratory sinus arrhythmia. Recorded with the software InnerBalanceTM Trainer (HeartMath Deutschland GmbH, Germany) and analyzed with the software HRV-Scanner (BioSign GmbH, Germany).
- Training evaluation [After the 4-week intervention (T1)]
