This randomized controlled study at University of Graz examines the impact of regular practice of an individual self-regulation training on psychophysiological well-being. Participants are randomly assigned to either intervention or control group. Individual self-regulation training is based on a self-regulation method used in NeuroDeescalation®. It combines elements of body movement or touch, breathing and self- encouragement. Participants in the intervention group get videos which support the acquisition of the individual self-regulation training, which should be practiced three times a day over a period of two weeks. In both groups HRV independent of metabolic demands (lmdHRV) is assessed the successive three days before and after intervention period. Furthermore, psychological variables are measured using items of the Positive and Negative Affect Schedule (PANAS), and the Mindful Attention Awareness Scale – State (MAAS – State). We expect that regular practice of an individual self-regulation training leads to higher increases in HRV independent of metabolic demands (lmdHRV), as well as higher increases in positive affect ratings, lower increases in negative affect ratings, and higher increases in state mindfulness from pre- to post- intervention compared to the control group. Statistical analyses will be conducted using mixed Analysis of Variance (ANOVA) to account for between-subjects factor (group) and within-subjects factor (measurement period).
