Extending the recovery window: Effects of trait rumination on subsequent evening cortisol following a laboratory performance stressor

摘要: Summary Mental rehearsal of past stressors through rumination may extend the physiological stress response and exposure to stress-related mediators, such as cortisol. If repeated over time, this prolonged activation contribute a number chronic health conditions. Findings from emerging literature on tendency ruminate its association with cortisol have been somewhat mixed. In present study, we tested whether trait predicted elevated concentrations in performance stressor, varied by social-evaluative context stressor gender. We also examined associations persisted into evening stressor. Participants (50% female; mean age = 19.83, SD  = 1.62) were randomly assigned complete laboratory speech either (SET; n  = 86) or non-evaluative (non-SET;  = 58). Salivary measured throughout visit later that evening. There was main effect greater total addition, interacted predict declines: night SET high ruminators did not exhibit typical declines Different patterns emerged for men women tendencies ruminate: higher scores had flatter slopes cortisol, whereas initial reactivity Together, these findings suggest relationship between is qualified individual differences (gender) characteristics (social-evaluative threat).
