Pain-related cognitive biases have been demonstrated in chronic pain patients, yet despite theoretical predictions are rarely investigated in combination. Combined cognitive biases were explored in individuals with chronic headache ( n = 17) and pain-free controls ( n = 20). Participants completed spatial cueing (attentional bias), sentence generation (interpretation bias) and free recall tasks (memory bias), with ambiguous sensory-pain, disability and neutral words. Individuals with chronic headache, relative to controls, showed significantly greater interpretation and memory biases favouring ambiguous sensory-pain words and interpretation bias favouring ambiguous disability words. No attentional bias was found. Further research is needed exploring the temporal pattern of cognitive biases.
疼痛相关的认知偏差在慢性疼痛患者中已经得到证实，但尽管理论上有预测，这些偏差很少被结合起来进行研究。本研究旨在探讨慢性头痛患者（n=17）和无痛对照者（n=20）是否存在联合认知偏差。参与者完成了空间提示（注意力偏差）、句子生成（解释偏差）和自由回忆任务（记忆偏差），使用的是模糊的感觉-疼痛、残疾和中性词。与对照组相比，慢性头痛患者在解释和记忆偏差上对模糊的感觉-疼痛词更有利，在解释偏差上对模糊的残疾词更有利。没有发现注意力偏差。需要进一步研究来探索认知偏差的时间模式。
