皮质醇觉醒反应（英语：Cortisol awakening response，CAR）是一种自然的代谢反应，可以被负面的认知情绪过程所强化，包括压力评估、负面情绪和沉思。然而，心理困扰和CAR并不总是相关的。性格正念的个体差异反映了人们如何与消极思想和情绪联系起来，这可能有助于解释这种不一致。我们测试了1）标记和描述内心体验的倾向以及2）不加判断地接受消极思想和感受的倾向是否会调节心理困扰与CAR之间的关联。自我报告的气质正念，感知压力，焦虑，负面影响，和反刍，和CAR超重/肥胖妇女进行了评估。回归分析进行了检查是否气质正念调节心理困扰和CAR的指标之间的关系。虽然心理困扰一直与CAR呈正相关，但这些关联通过与气质正念的两个组成部分的显著相互作用来限定。心理困扰与CAR在较低水平的气质正念，但不是在较高水平。这些发现支持了这样一种观点，即描述和接受痛苦经历的倾向可能会缓冲心理痛苦对生理唤醒的影响。这些元认知过程可能是解开心理困扰和生理应激反应之间复杂关系的重要调节剂。建议进一步研究，在其他人群中复制这种方法。
The cortisol awakening response (CAR) is a natural metabolic response that can be potentiated by negative cognitive-emotional processes, including stress appraisals, negative affect, and rumination. Psychological distress and the CAR are not consistently related, however. Individual differences in aspects of dispositional mindfulness which reflect how people relate to negative thoughts and emotions may help explain such inconsistencies. We tested whether the tendency to 1) label and describe inner experiences and 2) accept negative thoughts and feelings without judgment moderated the association between psychological distress and the CAR. Self-reported dispositional mindfulness, perceived stress, anxiety, negative affect, and rumination, and the CAR were assessed among overweight/obese women. Regression analyses were conducted to examine whether dispositional mindfulness moderated the relationship between indicators of psychological distress and the CAR. While psychological distress was consistently positively related to the CAR, these associations were qualified by significant interactions with both components of dispositional mindfulness. Psychological distress was associated with the CAR at lower levels of dispositional mindfulness but not at higher levels. These findings support the idea that the tendency to describe and accept distressing experiences may buffer the impact of psychological distress on physiological arousal. These metacognitive processes may be important moderators in unraveling the complex relationship between psychological distress and physiological stress reactivity. Further research is recommended to replicate this approach in other populations.
