在慢性疼痛中，精神挫败被认为是由反复发作的衰弱疼痛引发的一种致残类型的自我评估。这项探索性研究通过实验测试了激活的失败感对疼痛和情绪的影响，以及它与疼痛灾难的相互作用。参与者(N=71)被分配到高或低疼痛灾难组，然后随机分配接受失败或中性操作。在思维操作前后进行一项冷升压任务，测量疼痛阈值，同时测量精神失败、注意力、疼痛强度、疼痛预期以及情绪的视觉模拟评分。思维操控检查支持成功的失败激活。失意激活与增加的负面情绪和从伤害性刺激中的注意力分离有关，与疼痛灾难性倾向无关。疼痛阈值、疼痛或疼痛预期评级没有变化。结果表明，精神挫败可以通过自传体记忆任务在实验中被激活，激活的失败感似乎独立于疼痛、灾难性地影响情绪和注意力脱离伤害性刺激而运作。未来的研究可以利用我们的实验方法来评估激活的精神失败感对慢性疼痛患者的影响，对他们来说，疼痛的程度、情绪和注意力反应可能更强烈和更广泛。
In chronic pain, mental defeat is considered as a disabling type of self-evaluation triggered by repeated episodes of debilitating pain. This exploratory study experimentally tested the effect of an activated sense of defeat, as well as its interaction with pain catastrophizing, on pain and mood. Participants (N = 71) were allocated to either high or low pain catastrophizing groups and then randomly assigned to receive either defeat or neutral manipulations. A cold pressor task administered before and after the thought manipulation measured pain threshold, alongside visual analogue scales for mental defeat, attention, pain intensity, pain anticipation as well as mood. Thought manipulation checks supported successful defeat activation. Defeat activation was associated with increased negative mood and attentional disengagement from the nociceptive stimuli, irrespective of pain catastrophizing tendency. There were no changes in pain threshold, pain or pain anticipation ratings. The results suggest that mental defeat can be experimentally activated using an autobiographical memory task and that an activated sense of defeat appears to operate independently from pain catastrophizing in influencing mood and attentional disengagement from the nociceptive stimuli. Future research can utilize our experimental approach to evaluate the effect of an activated sense of mental defeat in people with chronic pain, for whom the magnitude of pain, mood and attentional responses may be stronger and broader.
