背景 在自我报告的不容忍不确定性 (IU) 方面得分较高的个人中,观察到将威胁关联更新为安全关联的困难。在此,我们试图确定基于认知行为治疗基本原理的指导是否可以促进 IU 水平较高的个体的安全学习,同时控制自我报告的特质焦虑 (STICSA)。方法 我们在一项关联威胁学习任务中测量了皮肤电导反应、瞳孔扩张和预期评级,其中参与者在威胁消除之前要么接受认知行为指令,要么不接受任何指令(n = 92)。结果分析显示,自我报告的 IU 和 STICSA 都类似地预测了皮肤电导反应的差异。只有在认知行为指导条件下 IU/STICSA 较低的个体才能通过皮肤电导反应表现出成功的安全学习。结论 这些初步结果提供了一些见解,让我们了解简单的认知行为指令与暴露相结合如何在不同程度的自我报告焦虑的个体中以不同的方式应用。结果进一步加深了我们对基本认知行为原则和自我报告的焦虑在安全学习中的作用的理解。
Background Difficulty updating threat associations to safe associations has been observed in individuals who score high in self-reported Intolerance of Uncertainty (IU). Here we sought to determine whether an instruction based on fundamental principles of Cognitive Behavioural Therapy could promote safety learning in individuals with higher levels of IU, whilst controlling for self-reported trait anxiety (STICSA). Methods We measured skin conductance response, pupil dilation and expectancy ratings during an associative threat learning task in which participants either received a cognitive behavioural instruction or no instruction prior to threat extinction ( n  = 92). Results Analyses revealed that both self-reported IU and STICSA similarly predicted differences in skin conductance response. Only individuals with lower IU/STICSA in the cognitive behavioural instruction condition displayed successful safety learning via skin conductance response. Conclusions These initial results provide some insight into how simple cognitive behavioural instructions combined with exposure are applied differently in individuals with varying levels of self-reported anxiety. The results further our understanding of the role of basic cognitive behavioural principles and self-reported anxiety in safety learning.
