Background: While perceived stress management skills attenuate peripheral endocrine stress responses, potential associations with central stress responses are unknown. Here, we investigated whether perceived stress management skills relate to neural activation changes in response to psychosocial stress induction using functional magnetic resonance imaging (fMRI).<br /><br />Methods: 26 healthy, middle-aged men (M = 53 years, SD = 13) underwent a standardized psychosocial stress task (Montreal Imaging Stress Task (MIST)) during a functional imaging scan. Perceived stress management skills were assessed using the Inventory for Assessment of Stress Management Skills (ISBF). Blood pressure was measured pre and post task.<br /><br />Results: Whole brain regression analyses of stress-related brain activations (compared to a control condition without social evaluative stress) showed a neural correlate within the insular cortex (t = 4.57, p = 0.005, uncorrected, k = 12), with a positive linear relationship with perceived stress management skills (r = 0.68, p < 0.001). Whereas participants with lower perceived stress management skills showed a stress-related reduction in brain activity within the right posterior insular cortex, participants with higher perceived stress management skills showed an increase in stress-related activity of this brain region.<br /><br />Conclusions: Our results indicate a specific stress-induced neural correlate of perceived stress management skills within the right posterior insular cortex. This suggests a central mechanism for stress protection with elevated perception of stress management skills.
