Individuals who are high in trait mindfulness are less stressed at work, better adjusted, and healthier than individuals who are low in this trait (Allen et al., 2015; Irving et al., 2009; Lomas et al., 2017) [1-3]. To date, trait mindfulness has not been considered within current, empirically supported, workplace stress models. Therefore, the present study explored if trait mindfulness, when used in conjunction with the Effort-Reward Imbalance model (Siegrist, 1996) (ERI [4]) better explains the links between workplace stress and non-adaptive physiological arousal. Across 2 timepoints (Summer-Winter) direct-care workers completed job stress (ERI), trait mindfulness, and health questionnaires and provided morning saliva samples to assess physiological indices of stress and ill-health. Compared across timepoints, changes in ERI and overcommitment were not associated with changes in the cortisol awakening response, salivary alpha amylase awakening response or secretory immunoglobulin A (sIgA). However, higher trait mindfulness was associated with increased sIgA. Potentially, trait mindfulness may act as a protective factor against ensuing ill-health and further, may be useful in better understanding the underlying mechanisms of the workplace stress-ill-health relationship.
个体特质正念水平高的人在工作中压力较小、适应能力更强、更健康，而特质正念水平低的人则相反（Allen 等人，2015 年；Irving 等人，2009 年；Lomas 等人，2017 年）[1-3]。迄今为止，特质正念尚未被纳入当前具有实证支持的工作场所压力模型中。因此，本研究探讨了特质正念是否与工作压力和非适应性生理唤醒之间的联系，当与努力-回报失衡模型（Siegrist，1996）（ERI[4]）结合使用时，是否能更好地解释这种联系。在 2 个时间点（夏季-冬季），直接护理人员完成了工作压力（ERI）、特质正念和健康问卷，并提供了早晨唾液样本，以评估应激和健康不良的生理指标。与时间点相比，ERI 和过度投入的变化与皮质醇觉醒反应、唾液α-淀粉酶觉醒反应或分泌型免疫球蛋白 A（sIgA）的变化无关。然而，较高的特质正念与 sIgA 的增加有关。特质正念可能是预防随后健康不良的保护因素，此外，它可能有助于更好地理解工作场所压力与健康不良之间的潜在机制。
