Key result
A 2-week HRV-biofeedback intervention did not significantly increase heart rate variability or general self-efficacy in unemployed subjects with adjustment disorder compared to a waiting control group.

Does HRV-biofeedback training improve heart rate variability and general self-efficacy in unemployed subjects with adjustment disorder?
A 2-week HRV-biofeedback training did not significantly improve heart rate variability or self-efficacy in unemployed individuals with adjustment disorder.
No support for 2-week HRV-biofeedback in unemployed patients with adjustment disorder; challenges short-term efficacy and warrants extended-protocol trials.
Background: Unemployment is a chronic stressor which is associated with higher levels of impaired physical and mental wellbeing, e.g. reduced heart rate variability (HRV) and decline in self-esteem and self-efficacy. The present study investigated the effectivity of a HRV-biofeedback-training in increasing HRV and general selfefficacy.

Petrowski et al. (2017) conducted an RCT in Adjustment disorder in unemployed individuals (n=22). HRV-biofeedback vs. Waiting control group was evaluated on Heart rate variability (RMSSD) and general self-efficacy. A 2-week HRV-biofeedback intervention did not significantly increase heart rate variability or general self-efficacy in unemployed subjects with adjustment disorder compared to a waiting control group.
