本研究验证了感知应对自我效能介导环境事件对儿茶酚胺分泌影响的假设。通过建立模型，诱导恐惧被试产生不同程度的自我效能感。他们的儿茶酚胺分泌水平随后被测量，以应对任务的高，中，低范围的自我效能感。高自我效能感伴随着低水平的血浆肾上腺素和去甲肾上腺素，而适度的自我效能感会引起血浆儿茶酚胺的大量增加。当恐惧症患者拒绝他们认为自己完全无效的任务时，两种儿茶酚胺都会急剧下降。相比之下，多巴胺的最大释放是由于对任务要求的统觉，恐惧症患者认为这压倒了他们的应对能力。当自我效能感被参与者模型强化到最大水平后，所有的任务都被执行，没有任何差异的儿茶酚胺反应。
The present research tested the hypothesis that perceived coping self-efficacy mediates the effects of environmental events on catecholamine secretion. Differential levels of perceived self-efficacy were induced in phobic subjects through modeling. Their level of catecholamine secretion was then measured as they were presented coping tasks in their high, medium, and low ranges of perceived self-efficacy. High perceived self-efficacy was accompanied by low levels of plasma epinephrine and norepinephrine during interaction with a phobic object, whereas moderate perceived self-inefficacy gave rise to substantial increases in plasma catecholamines. Both catecholamines dropped sharply when phobics declined tasks for which they judged themselves completely inefficacious. In contrast, dopac was released maximally by mere apperception of task demands that phobics regarded as overwhelming their coping capabilities. After perceived self-efficacy was strengthened to the maximal level by participant modeling, all of the tasks were performed without any differential catecholamine responses.
