疼痛恐惧对疼痛的影响及其认知机制

疼痛恐惧是把将要出现的疼痛刺激视为主要威胁而产生的一种恐惧,它会影响与疼痛相关的感知觉、注意、回避行为以及安慰剂止痛的效果.疼痛恐惧的认知模型主要有活动回避模型、恐惧-回避模型以及内感受性恐惧条件模型.未来的研究要进一步探究疼痛恐惧的认知机制,完善疼痛恐惧的认知模型并扩展疼痛恐惧的研究方法.

Fear of Pain: Effects on Pain Perception and Hypothesized Cognitive Mechanisms

Fear of pain refers to fear triggered by noxious stimuli appraised as potential threats to physical integrity. This paper reviews research on its' effects on pain perception, attention towards pain, avoidance behavior and placebo analgesia. In addition, leading explanations of fear of pain are outlined: the activity avoidance model, the fear-avoidance model and the interceptive fear conditioning model. Finally, select future research directions are discussed, particularly exploration of cognitive mechanism underlying fear of pain via applications of research methods from cognitive neurosciences.
