Previously we demonstrated that stressors varying on the dimension of mental effort and controllability have distinctive effects on cardiovascular, endocrine and immune system responses. The purpose of the present study was to relate individual differences in physiological stress responsivity to task appraisal and stress-induced mood changes (issue 1), trait characteristics (issue 2) and daily hassles (issue 3). Appraisal and mood changes did not mediate the differential effects of the stressors. The trait characteristics, aggression and external locus of control and daily hassles moderated the effect of the stressor on physiological parameters, especially immune parameters. Moreover, the moderation effect was different in the high versus the low effort stress task. High aggression, high external locus of control and more daily hassles were associated with increased reactivity in the low effort condition and decreased reactivity in the high effort condition, which is suggested to reflect less differentiated responding to changing task demands and hence, less flexibility in the immune system.

通过个性特征和日常麻烦调节生理压力反应：免疫系统反应的灵活性较低

此前，我们已经证明，在精神努力和可控性方面不同的压力源对心血管、内分泌和免疫系统反应具有独特的影响。本研究的目的是将生理压力反应的个体差异与任务评估和压力引起的情绪变化（问题 1）、特质特征（问题 2）和日常麻烦（问题 3）联系起来。评估和情绪变化并没有调节压力源的不同影响。性状特征、攻击性和外部控制点以及日常麻烦缓和了压力源对生理参数，尤其是免疫参数的影响。此外，在高强度压力任务和低强度压力任务中，调节效果是不同的。高攻击性，
