We explore the limits of the protective function of trait self-control in coping with sources of stress. Inspired by integrative self-control theory (ISCT) we predict that trait self-control only buffers the relationship between self-control demands and irritation when individuals have to cope with one source of stress, whereas in cases of two stressors, trait self-control fails to attenuate adverse effects. Samples consisted of occupational students (N = 163) and partly or fully or not formally employed students (N = 135). Job-related self-control demands (SCDs) did not predict strain when trait self-control was high and the other stressor (academic SCDs or weekly study time) was low, whereas strain was disproportionally higher and predicted by SCDs when trait self-control was low or the other stressor was high.

那些具有较高自我控制能力的人何时会遭受压力？

我们探索应对压力源时特质自我控制的保护功能的局限性。受综合自我控制理论（ISCT）的启发，我们预测特质自我控制仅在个人必须应对一种压力源时才缓冲自我控制需求与刺激之间的关系，而在两个压力源的情况下，特质自我控制无法减轻不良影响。样本包括职业学生（N = 163）和部分或全部或未正式就业的学生（N = 135）。与工作相关的自我控制需求（SCD）不能预测特质自我控制较高时的压力，而其他压力源（学术SCD或每周学习时间）较低，而压力特异地较高，当特质自我控制时压力由SCD预测较低或其他压力源较高。
