Participants are asked to think of three strength which have helped them in prior stressful events. They then have to think of ways how these strength may help them in future stressful situations, i.e. a test in this experiment.
Participants listen to an audio-instruction on cognitive defusion. They shall observe the thoughts and feelings of stress and, with the help of the instruction, distance themselves from it.
No Intervention: Control
Participants wait for the stress-test to start.
- Change in Subjective Stress Ratings [ Time Frame: at baseline, before the intervention, after the intervention; during the stressor, after the stressor; in total 45 minutes ]VAS (visual analogue scale)
- Change in Cortisol Levels [ Time Frame: at baseline (min. -37), after the intervention (min. -19), after the stressor (min. 0), recovery 1 (min. +15), recovery 2 (min. +30); in total 67 minutes ]saliva sample
- Changes in Heart-Rate-Variability (HRV) [ Time Frame: during baseline (duration 10 minutes), during the stressor (duration 20 minutes), during recovery (duration 10 minutes); in total 40 minutes ]electrocardiogram
- Changes in Affect [ Time Frame: at baseline, after the stressor; in total 45 minutes ]VAS (visual analogue scale)
- Self-Efficacy [ Time Frame: at baseline, after the recovery-phase; in total 55 minutes ]questionnaire (self-efficacy scale; Schwarzer & Jerusalem, 1999)
- Positivity [ Time Frame: at baseline, after the recovery-phase; in total 55 minutes ]questionnaire (positivity scale; Caprara et al., 2012, König, 2012)
