Trait and state self-compassion interactively predict cortisol recovery following an acute stressor in healthy males

This study examined the effect of self-compassion induction on cortisol stress recovery following an acute stressor. A total of 67 male university students completed the Maastricht Acute Stress Test and were then randomized to either a self-compassion (a guided self-compassion writing task) or control condition (a writing task just to review the stress test), followed by a 50-minute resting period. Subjective stress and cortisol levels were assessed at - 15, - 10, 0, 10, 20, 30, 40, and 50 min relative to the stress offset. Heart rate and respiratory sinus arrhythmia were monitored throughout the study. Multilevel modeling indicated that self-compassion induction had no significant effect on cortisol recovery. An exploratory analysis examining the moderating effect of trait self-compassion indicated that the effect of self-compassion induction was prominent when trait self-compassion was low but not when it was high. These findings suggest that self-compassion induction may help recovery from stressful experiences, particularly for those who are less self-compassionate.
